Natural Tooth as the Permanent Reconstruction After Immediate Implantation in the Esthetic Zone of Periodontally Compromised Patients.

This case series describes a treatment method in which the natural tooth was used as the temporary and permanent reconstruction after immediate implantation in the esthetic zone of periodontally compromised patients. Five patients with a hopeless tooth in the esthetic zone due to periodontal causes were included. The tooth was extracted, and immediate implantation protocol was followed. The extracted tooth was adapted over a temporary abutment during the osseointegration period, and the same tooth served as...

Immediate One-Time Low-Profile Abutment to Enhance Peri-implant Soft and Hard Tissue Stability in the Esthetic Zone.

Reductions in peri-implant bone height have been acknowledged as a normal consequence of implant therapy. Various restorative factors contribute to this phenomenon. One is repeated abutment retightening, which causes a mechanical disruption at the implant-abutment interface, leading to soft tissue recession. Several investigators proposed placement of the definitive abutment after implant placement as a solution to the problem. The definitive use of an intermediate abutment after implant placement seems to ...

The compression dome concept: the restorative implications.

Evidence now supports the concept that the enamel on a tooth acts like a compression dome, much like the dome of a cathedral. With an overlying enamel compression dome, the underlying dentin is protected from damaging tensile forces. Disruption of a compression system leads to significant shifts in load pathways. The clinical restorative implications are significant and far-reaching. Cutting the wrong areas of a tooth exposes the underlying dentin to tensile forces that exceed natural design parameters. The...
