Stress distribution in the transitional peri-implant bone in a single implant-supported prosthesis with platform-switching under different angulated loads.

A 3D finite element analysis was conducted to evaluate and compare the stress distribution in the peri-implant bone (transitional cortical and trabecular bone) of one single implant-supported crown with platform switching and another without platform switching, under a vertical and an oblique load. Two models were created, simulating an osseointegrated implant (4 × 13 mm, platform 4.1 mm) embedded in the jaw bone.

Orthodontic and prosthodontic treatment in dental avulsion cases.

A clinical case of traumatic dental avulsion with endodontics, replantation and bracket fixation is presented. Subsequent follow-up led to extraction of the replanted teeth. The edentulous space was restored with a Maryland bridge.
