Transitional bonding allows dentists to make major or minor changes in occlusion and esthetics with little or no reduction of tooth structure. It can be often done in one visit. With this approach it is possible to address cases with various esthetic problems, and, perhaps more important, health issues can often be treated. Examples include wear from grinding of clenching; loss of chewing tooth structure from erosion, decay, or fractures; and numerous teeth missing. Such situations may cause a decrease in vertical dimension leading to esthetic and functional problems. Restoring teeth that have worn down or are developmentally small so that the teeth are long enough or large enough to look more attractive without opening the bite could create a very deep overbite or other negative change. By increasing the bite opening one can often compensate for that. Opening the bite allows more space or clearance for restoring wear and lengthening the teeth. Most people will experience some collapse in their bite with age. Many adults by the age of 50 could benefit from treatment that lengthens teeth for esthetic and/or functional improvements.
A significant advantage of using composite and the transitional bonding procedure is that it is possible to be extremely conservative in maintaining tooth structure. The great majority of cases require little or no preparation. If preparation is needed, it is more conservative than with any other option. Another advantage is that these restorations are very easy to adjust as the dentist is refining occlusion or completing esthetic contouring. The composite can be reduced quite quickly or can be added to without much difficulty, if necessary.
