About Me:
New York City Cosmetic Dentist Dr. Judy Johnson founded the Dentalvisits website in 2001 as a technology improvement resource for dentists, and now more than 90,000 medical and dental professionals with expertise in retrieving, interpreting, and applying the results from scientific studies developed in cosmetic and implant dentistry, endodontic and periodontic care, pediatric and prosthodontic care, oral surgery and restorative dentistry, promote overall search engine recognition of public evidence-based medicine by publishing informed decision public health articles to the rapidly accumulating body of research that constitutes our website's education development initiative in communicating the risks, diagnosis and treatment benefits of different clinical courses of action. Ultimately, better dental choices facilitate improvements in patient care at Dental Visits Cosmetic Dentistry Centers.

Do you have ten (10) MySpace family members, co-workers, business associates, neighbors, civic, church or gym buddies with really bad teeth, who could benefit immediately from community cosmetic dentistry services? We would love to hear more stories about their overdue cosmetic smile makeovers... Please write to us, submit posts on our comments and tell us their stories! Happily, we'll be managing the responsibility and aggressively funding the treatment for ten thousand (10,000) MySpace smilemakeover models until the expiration date December 31, 2008.

For MySpace Friends to become eligible candidates and models for the cosmetic dentistry smile makeover, the qualifications are:

(1) Post letters on Dr. Johnson's Friends Comments requesting cosmetic treatment.
(2) Reference "HELP ME DENTIST! I NEED A SMILEMD 160 RESTORATION" in the title statement of the letter.
(3) Each individual post must include a photo for positive identification (no exceptions).
(4) Only Dr. Johnson's friends can benefit or make requests for community cosmetic service.

That's equivalent to a full mouth thirty-five thousand dollar ($35.000.00) community service value which may include the ZOOM One-Hour Professional Teeth Whitening. It will enable one MySpace friend to take a step closer to those beautiful brighter smiles that are seen on ABC's hit television show Extreme Makeover.

MySpace has about 70 million registered users in the United States. Any statistical reference would represent estimates relative to approximately 10 million uninsured health insurance users nationally. At the very least, we believe 500,000 (5% percentile) have untreated dental conditions and therefore anticipate identifying on or before April 7th, 2008, a true sampling estimate of 25,000 potential candidates within the MySpace registered user population.

The deadline to complete the initial diagnosis for the 25,000 potential candidates is established for May 19th, 2008. We have decided that our treatment benefit ratio for the different clinical courses of action, be capped at 2 to 5 (40%) candidate applicants or 10,000 community service models, with the provision that all our dentists provide cosmetic treatment records and every patient fully discloses the relavent proceedural content of each visit as a Dr. Johnson's Friends Comment during the year January 1, 2008 through December 31, 2008.

Rising prices for medical care are making it harder for the average American to afford health insurance, leaving 47 million uninsured. We're seeking ten thousand (10,000) community cosmetic dentistry candidates for whole new smilemakeovers, just post us a comment and we'll give you an opportunity to have a multi-national news's media smile.

The "SmileMD 160" service mark represents a guaranteed smile makeover because each doctor owns and independently controls the clinical operations at each http://www.dentalvisits.com facility where a professional team of restorative dentists annually contribute community cosmetic dentistry services to make the difference in the everyday life of at least one (1) MySpace friend.

Dental Visits permanent membership dentists will only be permitted to select their potential patients for the beneficiary cosmetic dentistry smile makeover from posts to Dr. Johnson's Friends Comments. The final decision and the rights to determine the selection of any MySpace friend is reserved for the sole custody and entrusted to the judgment of the team of doctors along with the preparation of the cosmetic dentistry smile makeover treatments.

Dental Visits inherently desires to consistently contribute resolutions to fix those dental problems that develop because of restrictions and limitations imposed on healthcare resources, these dental procedures are just standard, available in-office practices at Dental Visits Cosmetic Dentistry Centers.

The primary disadvantages confronting many of today's young adults and teenagers are dental braces, bad breath, gum disease treatment, root canals, dentures, dental implants, amalgam and composite fillings, sealants, orthodontics, oral surgery, pediatric dentistry, crowns and bridges, TMJ therapy, tobacco cessation, veneers, cosmetic teeth whitening and nutrition counseling.

All compilations from posts will collectively represent samplings of the list of bona fide volunteers. Observance and adhering to this criterion will provide the viewing public with evidence and the supporting documentation to facilitate necessary overviews of any "Oprah Winfrey Cosmetic Smile Makeover!"

How cosmetic dentistry restoratives advanced dental care.
by Judy Johnson DDS

Traditionally, metallurgical materials were used for restorations. This was a very well established practice for the best part of 150 years. In the case of fillings, silver amalgams were used to a large extent worldwide. These amalgams are 50 percent powder - composed of silver, tin, copper and a trace amount of zinc, and 50 percent liquid - which is pure mercury - amalgamated to form a paste, which is placed into the cavity. The silver amalgamates by reacting with the free mercury, while the copper interacts with the tin to create a cupric-tin complex strengthening/hardening interphase and the zinc acts like a scavenger to rid any unreacted metallic oxide residue. This material is not very technique sensitive, with near zero handling/manipulation error characteristics, so it's advantageous to the clinician due to the fact that it can be placed in a slightly moist environment, forgiving to isolation technique acuity, in lieu of deleterious effects to its tooth-margin interfacial integrity. However, there are serious disadvantages to this type of silver amalgam material in comparison to the modern poly-ceram composite fillings.

The importance and advantages of using optimum materials and products with high aesthetic quality and state of- the-art materials in modern restorative dentistry. Firstly, they are easier to use, secondly, they require less machinery and equipment in the laboratory and thirdly, chair-side time is significantly reduced. There are other advantages of modern restorative materials, if we look at dental restorations in a chronological manner from infancy to adulthood, from pediatric dentistry to geriatric dentistry. We start out with a little tiny one-surface cavity, that escalates to a two-surface filling, then possibly leaks and has to be repaired and becomes a pin-retented three - or four-surface silver amalgam filling undermining the surrounding enamel, and then onward to a crown (usually poorly adapted or sealed), followed by endodontic treatment and a post/core build-up encapsulated by a crown prosthesis and possibly an extraction, even a bridge, usually non precious alloy (porcelain fused to metal), subsequent alveolar bone resorption and then possibly a removable prosthesis; partial or denture followed by ridge augmentation and possibly an implant.

The main disadvantages to this more sophisticated material is that it requires a dry field of operation during the momentary placement procedure, however, I think the advantages outweigh the disadvantages due to the fact that one has a material that is functional, aesthetic, matches tooth color, that is serviceable and is biocompatible, healthier overall compared to the traditional silver amalgam fillings and the standard crown and bridge alloys; nickel chrome, chrome-cobalt and silver-palladium products. With traditional materials it takes two to three days and an innumerable amount of equipment, instruments and adjunct materials before a crown or a bridge is fabricated, whereas with our materials one is able to fabricate a rather vast or large restoration in less than one hour. So from a time, effort and equipment perspective, this is the preferred methodology for the laboratory.

Because silver amalgams are very limited they usually have to be repaired somewhere down the line. By the time they have to be repaired, the carious lesion site usually has progressed so vastly that it invariably turns into a three-quarter crown or a full crown. On occasions, one even has to resort to crown and bridgework. The approach with the new modern poly-ceram restorative materials is that if one can achieve a very good seal at a tooth restorative interface, which is really the hub or area of concentration of the technology, and then one can reduce the possibility of having to remake the restoration and ensue this very tedious and complicated voyage. This is not the case with the advanced restorative materials. If there is a failure it tends to be rather minor and require very quick patch-up and repair at the adhesive interface and so the incidences of secondary caries, remakes or repairs is significantly lower in potential expenditure and tooth loss. Which is a massive advantage whether you are in Prague, London or New York City.

There is a propensity to judge today's restoratives of the poly-ceram category by 'bunching them' with those of 40 years ago, particularly among dentists who were accustomed to those products then. However, composites or bonding materials from 40 years ago are a far cry from what is available today. Since then, we have gone through about seven generations of products and probably tens of thousands of research projects documented in the form of manuscripts and patents, so there has been a good deal of innovative progression in this field of technology.

Consequently, today there are several products that are very reliable. From the perspective of wear resistance, today's restoratives are able to sustain wear that is as low as three micrometers per year - which rivals actual enamel. This compares with 40 years ago when it was 150 micrometers per year. According to statistics from pooled clinical data, today's restoratives have an average half-life of 17-22 years, which is very close to a silver amalgam restoration and or porcelain fused to metal crown. From a color stability perspective these products no longer have residual oxide by-products, they tend to be very stable and tend to maintain their anatomical form, contour and texture and overall physico-mechanical functional state. So yes, there are still some materials today that are not very reliable, and then, there are a few materials that are extremely advanced and are capable of rivaling any metallurgical or ceramic adjunct material.

In the long run they save so much time that they work out to be more economical. Cost is certainly one element, but in today's society people are more health conscious and aesthetically aware, which are also factors that need to be considered. I think that a silver restoration for a posterior molar tooth is 50/50. No one looks back there so it may not be too important. However, for an anterior restoration there is really no choice in the matter, the thought of seeing gold or silver as you smile is rather awkward, therefore, more aesthetically pleasing materials become a matter of necessity. So for the anterior sector of the intra-oral environment it is a necessity. Furthermore, as far as the laboratory technician is concerned, modern materials are quicker and easier to use so there is really no reason why they should not be chosen.

The silver amalgam is not tooth colored and is rather obvious when placed in the anterior sector of the oral environment. However, the modern poly-ceram composite can attain a near perfect tooth color match. Further, in the event the silver amalgam is applied beyond one third of the cuspal incline, it tends to undermine the surrounding thin-walled remaining enamel leading to cuspal fracture and/or radial cracks compromising the retentive surrounding tooth aspects, or the restoration itself. The poly-ceram is capable of achieving a chemical bond-linkage to the underlying organic dentin and a micro-mechanical bond to the surrounding enamel honeycomb prismatic structure with the aid of modern seventh generation adhesive technology.

This allows for a more conservative approach to tooth preparation guidelines criteria, with a greater emphasis on conservation of sound non-carious tooth structure. Conversely, such advances in adhesion technology have allowed for more substantial, larger restorations, in lieu of hampering the strength of the remaining tooth structure, especially with the advent of extra-oral processed inlay-onlay (three-quarter)-crown luted cemented restorations.

The metallurgical silver-amalgam product is electrically conductive, so it is not the most pleasant material to have in your mouth. By contrast, the poly-ceram composite filling is electrically non-conductive. The silver amalgam also undergoes an abrasion phenomenon leading to degradation, allowing the leaching of certain mercuric contents from the filling, which have been known to affect certain kidney and liver enzymes and even permeate the blood brain barrier. Although, the mercuric salt differs from the free mercury in its unamalgamated form, this remains a controversial issue.

Whereas the poly-ceram composites of the 1960s ensued upward of 150 micron wears per year, today's (circa 1993-2003) modern poly-ceram composites are able to sustain a clinical wear rate of 3-35 microns per year, a pivotal improvement. The corrosion by-product of the dental silver amalgam serendipitously seals the tooth restoration margin, in lieu of chemical adhesion, otherwise known as the Gamma-II Phase. In order to passivate this corrosion phenomena, both marginal breakdown, surface pit-corrosion patterns and tarnish, high copper amalgams were innovated, however, a clear disadvantage of the accentuation of the Gamma-I Phase is that it leads to more prevalent bulk fracture and facilitated mercuric salt by-product release.

The G.V. Black rules of cavity preparation protocol innovated in 1898, and still practiced today, state the necessity of 'extension for prevention', in other words extending the cavity preparation/excavation beyond the carious limit zone in order to prevent recurring caries, thereby, consuming more tooth structure. In addition, due to the fact that silver amalgams do not chemically adhere to tooth structure, creating diatoric forms, undercuts, channeling and macro-mechanical retentive sites during the cavity preparation is both necessary to retent the amalgam as well as deleterious in sacrificing more sound tooth structure. On such occasion that the tooth preparation has been compromised to a great extent, the tendency is to use gold retentive pins in order to anchor and sustain the silver-mercury admix, a further unnecessary invasive step.

Previous research has shown that a silver amalgam 'MOD' 3- surface, slot-like cavity preparation, restored class II molar tooth, sustains only 50 percent of a sound unrestored molar intercuspal flexural strength. Further, a modern poly-ceram composite restoration strengthens the tooth to 2xfold its potential intercuspal transverse strength. Silver amalgams used in large class II molar restorations; invariably cause a tattoo phenomenon of permanent tooth discoloration to a violet-gray/green tinge and even brown/black tint, this is quite evident when a clinician attempts the removal, replacement or repair of a failing old silver-amalgam restoration. This is not the case with modern poly-ceram composite filling materials. As a consequence, such restorations have, over the past 20-25 years, become less and less popular and alternatives, otherwise known as bonding or white fillings (or more prevalently known as composites) are now available.

A particular area of specialty lies with these alternative restorations, which are composed of polymeric materials and glass ceramic fillers for reinforcement. Such restorations are used for a plethora of intraoral care including liners, cement, sealants, class V cervical erosion sites, and direct fillings, class I, II, III and IV in anterior and posterior tooth restoration. They were originally available in auto cure format (2-part systems) throughout the 1950-60s, then in photo cure UV-light initiated (200-400 nanometers). In the early 1970s and in the late 1970s the entire industry merged to photo cure blue or halogen light cure materials, which are initiated by a blue light ranging from 400 to 700 nanometers wavelength irradiated for 10-40 seconds. The light triggers a free-radical addition reaction in the material that converts it from a monomer (liquid state) to a polymer (solid form), hardened material.

Such materials have experienced a lot of problems, most of which have been resolved over the years, as the technology has become more refined. Our area of concentration and original innovation is the semi-crystalline poly-ceram nano-reinforced technology, and the particular line adjunct and borne of this pivotal innovation is the Diamond product line. There is an entire series affiliated with this ranging from the advanced adhesive, DiamondBond, the liner/cement/sealant, DiamondLink, the filling material, DiamondLite to the prosthodontic, crown and bridge system, DiamondCrown. It is the crystalline morphology and special oligomer-ceram interfacial characteristics that affords these materials certain physical, mechanical, optical and wear resistance properties that rival the standard amorphous polymer composites.

This special technology has afforded improved color stability, better tooth color matching ability, significantly higher fracture strength resistance, near-zero leaching/solubility, tremendous wear resistance, negligible polymerization-contraction forces, shrinkage, substantially improved tooth-adhesive marginal integrity due to advanced bonding mechanisms, biocompatible formulation and remarkable toughness, shock absorbing character, carrying this technology above the norm of the restorative niche into the realm of reconstructive materials, including prosthetics and implantology.

Of special interest is field prosthodontics and implantology due to the fact that the traditional superstructure encapsulating or crowning the underlying metallic alloy substructure is usually dental porcelain characterized as a very hard and brittle surface that is relatively unforgiving and complex in its laboratory application methodology. The PFM (porcelain fused to metal) restoration, although very popular, is infused with a spectrum of relative disadvantages:

i. The mechanical properties of dental porcelain exhibit an unusually hard material, four times that of natural tooth structure, which is rather non-forgiving, wears opposing dentition, weak in tension and flexure mode (low strength), and most importantly attains very low toughness, hence, unable to dissipate cyclic masticatory energy. Therefore, it is prone to fracture, delamination from the underlying retentive metal framework, eventually necessitating complex intra/extra-oral repair.

ii. This is further complicated by the use of popular dental alloys as the copings or frameworks for these dental porcelains such as nickel chrome and silver-palladium, which have been documented to ensue cytotoxic reactivity with the intraoral epithelial mucous membrane soft tissue contact zones, leading to cervical erosion, pocket formation, degradation of the interdentinal papillae and loss of periodontal ligature attachment, accelerating mobility and jeopardizing the overall stability of tooth structural-architectural ergonomics.

iii. The underlying metallic substructure lack of aesthetic quality or tooth color matching ability necessitates greater tooth structure compromise in order to plunge the metallic collar of the crown restoration, yielding a cervical margin below the gingival gum-tissue line, sub gingival. This leads to further bio-interaction at the sulcus with perio-ligature deterioration and poor hygienic maintenance due to inaccessibility to tooth brushing and dentifrice activity.

iv. These factors collectively are of great ramification when such materials, dental porcelain, are used in implant prosthodontics. Especially in single implants and the more popular immediate loading techniques, where the shock absorbing, high toughness, form and functional maintenance coupled with superb aesthetics of the semi-crystalline poly-ceram nano-reinforced DiamondCrown technology rivals any dental porcelain titanium implant superstructure. This is of great importance in particularly frail osseo integration transitional implant-prosthesis (crown) loading periods that will dictate the eventual success rate of the implant prosthesis integration and maintenance thereof.

Further, in complicated cases where temporomadibular joint disorder is prevalent and eventual characteristic tooth bruxism and jaw-clenching phenomena are evident, the semi-crystalline DiamondCrown technology, serves its purpose par excellence as the restorative of choice for occlusal rehabilitation. Whereby the shock-absorbing, cyclic masticatory energy dissipating special micro morphology of the crystalline lamellae leads to a micro elastic behavior, the reinforcing poly-ceram interdendritic structure allows for macro rigidity and architectural stability in spite of the tormented occlusal disappropriation. Further, enhanced by the ability to repair and maintain intra-orally opposed to the standard of the industry, dental gold.Workshops undertaking specific training with an entire team of technologists, clinicians and scientists would be advisable before using new restorative materials.

Training and education brings about the real success in this restorative science and is a key factor in disseminating the proper methodology and operative techniques affiliated with this new generation of materials. The learning curve associated with the older generation metallurgical materials, from an intra-oral placement care point of view, is not very steep, so in order to become more adept at this type of restorative dentistry, it is very important to hold clinics, workshops and get-togethers or even chair-side practical workshops to bring about greater awareness as to what is the proper either surgical, operative or technical protocols that bring about a higher chair-side success rate, their corresponding clinical indications and material ramifications, help generate a greater awareness of the proper clinical methodologies associated with advanced biomaterials chemical engineering. http://www.dentalvisits.com

Artistic Vision

Posted by Stacy Esch on November 6, 2023 at 8:15pm 10 Comments

Is an artist's "vision" primarily a product of experience or imagination? I don't want to pursue the simple answer that it's both. Is it primarily one or the other, of if it's just plain old both, how do they interact to create an imaginary world?

Is it true that some people have more artistic vision than others, or is this kind of seeing equally available to all?

Trying to find treatment.
