摘要:

The technique of reattaching traumatically fractured crownsegmentsusing bonded tooth‐colored materials has improved over the last decade. The latest advancement is the use of a new visible light‐hardened glass ionomer material for rapid initial replacement of detached coronal structure. This paper demonstrates a step‐by‐step procedure for coronal repair using light‐hardened glass ionomer material and application of broad plane bonded composite resin for strength and natural a

摘要:

Shade guides that are included in most composite kits are not made of the actual resin material. Therefore the true shade, translucency, or opacity of the composite resin is not readily apparent with stock shade guides. Due to this fact, it has become evident that the best solution to the shade guide problem is to construct a custom shade guide from the actual resin. Until recently, fabrication of custom shade guides has been a time‐consuming, inefficient task. Now, a simple and efficient method of forming accurate shade guides for composites is available. With its unique handle/template design, T‐TABsTMenable a dentist to create a precise, labeled shade guide within minutes. There are many advantages to both dentist and patient when T‐TABs are employed in the construction of custom shade g

摘要:

The use of an acid‐etch enamel resin bonded Class III restoration allows for a more conservative cavity design. The acid‐etch technique's benefits include retention without dentinal undercuts and creating reinforcement of undermined enamel. When a controlled method of acid‐etched enamel resin‐bonding with a syringe technique is used with a visible light curing composite resin, a durable, esthetic Class III restoration is a

摘要:

The use of today's highly sophisticated dental materials has required a corresponding increase in the technical skills of the operator. Surgical telescopes with high resolution and contrast are replacing plastic lenses of somewhat lesser quality. Moreover, depending on their frame mounting, these ground glass magnifiers are also offering the operator additional comfort and safety. The problem for the dentist, however, is to assess properly the products currently being presented by manufacturers. A detailed description of each device offered by four major suppliers is given relative to true field width and depth, working distance or range, “down time” during prescription changes, usefulness with correction, operator positioning, light admittance, degrees of magnification available, and expense. Photographs of the operator practicing without magnification and then using each of three devices is shown and analyzed. With some exceptions, those instruments providing the most flexibility as regards the above factors are most worthy of the dentist's considerat

摘要:

The introduction of new porcelain materials used in combination with vastly improved bonding materials and techniques have virtually revolutionized the use of conservative esthetic bonded prosthetic restorations fabricated without the need for metal substructures. Missing anterior teeth in selected cases may be replaced by all porcelain veneer bridges that are accomplished with more conservation of natural tooth structure of the abutment teeth as compared to traditional procedures. A total of 12 all porcelain veneer bridges were monitored for varying periods up to 24 months postoperatively, during which time no fractures occurred. The authors have attributed this high early success rate primarily to several factors, namely (1) case selection, (2) bulk of porcelain at the sides of the major connectors, and (3) adjustment of occlusion and articulation with the opposing teeth.
