Anatomic consideration for preventive implantation.

The aim of preventive implant therapy is to prevent or delay loss of alveolar ridge bone mass. For use in an anatomic study of 60 mandibles, resorption of the alveolar ridge was classified into four preventive stages: (1) after extraction of teeth; (2) after initial resorption; (3) when the ridge has atrophied to a knife-edge shape; and (4) when only basal bone remains. Implantation in stage 3 necessitates removal of the knife-edge ridge to create space for cylindrical implants. Therefore, implantation in stage 2 is advocated to prevent the development of stage 3. The aim of implantation in stage 4 is to prevent total loss of function of the atrophic mandible.

All porcelain anterior veneer bridges.

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.
