Amalgam has been used to restore teeth Federal, state and local environmental agencies regulate for levels of affected by decay for more than a hundred years. More recently, “total mercury” because it does not degrade and can change from other materials, such as composite resins, have provided dentists one form to another, allowing it to migrate through the environment, and patients with an option other than amalgam, and because though there is insufficient scientific evidence that dental amalgam in composite restorations can match tooth color, they have become more the environment is a significant source of methylmercury. popular than the silver colored dental amalgam. However, because of its greater durability and adaptability than alternative materials, Nonetheless, it is prudent for dentistry to take steps to reduce the amalgam is still considered the best option for certain restorations, release of amalgam waste or any potentially harmful materials to the especially where the filling may be subjected to heavy wear, or where environment because dentistry’s role as a public health profession it is difficult to maintain a dry field during placement. Also, because naturally includes environmental stewardship. Organized dentistry amalgam material is less costly than composite material, it often encourages and supports constructive dialogue with individuals and represents a more economical choice for patients. -
THE GERALD D. STIBBS GOLD FOIL SEMINAR MANUAL (Updated 2017)
THE GERALD D. STIBBS GOLD FOIL SEMINAR MANUAL (Updated 2017) COPYING: Any and all are welcome to use the contents of this manual in their efforts to improve their own restorative service and competence. This does not give or imply the right to reproduce the material as being the product of any other individual or group. If copied please continue to give credit to those who produced the work. DR. GERALD D. STIBBS This course is dedicated to the memory of Dr. Gerald D. Stibbs, who in the course of his career influenced the development of so many dentists, and carried on the tradition of excellence that began with Dr. W. I. Ferrier. Some insight into Dr. Stibbs character can be gained from the preface to one of his manuals: “To achieve competence with gold foil, one must read and more importantly, practice repeatedly the steps involved. While it is possible to become adept on one’s own initiative it is more practical to become an operating member of a study club that meets regularly, under the close supervision and coaching of a competent instructor. Courses of various time lengths have been given in these procedures. In general it is best for the beginner to plan on a ten-day program, given in either a single course, or in two five –day courses. With less than a five-day exposure, there is a tendency for the inevitable problems to surface in two or three days, and there is not enough time to overcome the difficulties. For refresher courses, three to five days of exposure are advisable. -

General& Restorative Dentistry
General& Restorative Dentistry Fillings 1. Amalgam restorations ( for small, medium large restorations) 2. Direct composite restorations (for small – medium restorations) 3. Glass ionomer restorations (for small restorations) 4. CEREC all ceramic restorations ( for medium – large restorations) Amalgam restorations: Every dental material used to rebuild teeth has advantages and disadvantages. Dental amalgam or silver fillings have been around for over 150 years. Amalgam is composed of silver, tin, copper, mercury and zinc. Amalgam fillings are relatively inexpensive, durable and time-tested. Amalgam fillings are considered un-aesthetic because they blacken over time and can give teeth a grey appearance, and they do not strengthen the tooth. Some people worry about the potential for mercury in dental amalgam to leak out and cause a wide variety of ailments. At this stage such allegations are unsubstantiated in the wider community and the NHMRC still considers amalgam restorations as a safe material to use in the adult patient. Composite restorations: Composite fillings are composed of a tooth-coloured plastic mixture filled with glass (silicon dioxide). Introduced in the 1960s, dental composites were confined to the front teeth because they were not strong enough to withstand the pressure and wear generated by the back teeth. Since then, composites have been significantly improved and can be successfully placed in the back teeth as well. Composite fillings are the material of choice for repairing the front teeth. Aesthetics are the main advantage, since dentists can blend shades to create a colour nearly identical to that of the actual tooth. Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage and insulate the tooth from excessive temperature changes. -
FAQ's for PORCELAIN VENEERS
NEW YORK SMILE INSTITUTE AESTHETIC & IMPLANT DENTISTRY FAQ’s for PORCELAIN VENEERS Q & A. Q. What happens to my teeth after veneers, and will I ever get cavities? A. The integrity of veneered teeth is only marginally compromised, and the veneer is bonded to the existing teeth. There is no higher incidence of decay provided that the veneers are properly cared for as detailed above, regular brushing with toothpaste, and flossing. Keep your sugar consumption low and confined to meal times, good dental advice generally to prevent decay. Q. How long does porcelain veneers last? A. In my experience they can last from 7 to 20 years. While the veneer itself is inert and non-living, the tooth or teeth to which they are attached, and the surrounding gum tissues are living and may change. For example, gum line shrinkage may expose or reveal root surfaces. If a veneer comes off it can generally be rebounded. If it chips it can sometimes be rebounded or otherwise replaced. Q. Do porcelain veneers stain with normal things like tea, coffee and wine? A. Porcelain veneers should never stain, however if your teeth have a propensity to stain you should try to avoid or minimize the behaviors that lead to staining, and look after them as recommended above with normal hygiene and maintenance procedures. NEW YORK SMILE INSTITUTE AESTHETIC & IMPLANT DENTISTRY Q. If I have my upper teeth treated with porcelain veneers will my lower teeth still be a different color, or more yellow? A. This is certainly a factor that will be discussed during your evaluation and smile design so that everything matches and blends well. -
DENTAL MATERIALS FACT SHEET June 2001
DENTAL MATERIALS FACT SHEET June 2001 Received from the Dental Board of California As required by Chapter 934, Statutes of 1992, the Dental Board of California has prepared this fact sheet to summarize information on the most frequently used restorative dental materials. Information on this fact sheet is intended to encourage discussion between the patient and dentist regarding the selection of dental materials best suited for the patient’s dental needs. It is not intended to be a complete guide to dental materials science. The most frequently used materials in restorative dentistry are amalgam, composite resin, glass ionomer cement, resin-ionomer cement, porcelain (ceramic), porcelain (fused-to-metal), gold alloys (noble) and nickel or cobalt-chrome (base metal) alloys. Each material has its own advantages and disadvantages, benefits and risks. These and other relevant factors are compared in the attached matrix titled “Comparisons of Restorative Dental Materials.” A “Glossary of Terms” is also attached to assist the reader in understanding the terms used. The statements made are supported by relevant, credible dental research published mainly between 1993 - 2001. In some cases, where contemporary research is sparse, we have indicated our best perceptions based upon information that predates 1993. The reader should be aware that the outcome of dental treatment or durability of a restoration is not solely a function of the material from which the restoration was made. The durability of any restoration is influenced by the dentist’s technique when placing the restoration, the ancillary materials used in the procedure, and the patient’s cooperation during the procedure. Following restoration of the teeth, the longevity of the restoration will be strongly influenced by the patient’s compliance with dental hygiene and home care, their diet and chewing habits. -
