Implants placed in immediate function in periodontally compromised sites: a five-year retrospective and one-year prospective study.

Statement Of Problem: Placing implants in periodontally compromised sites is generally considered a risk factor. Good results have been reported when rehabilitating partial or complete edentulous sites in patients with a history of periodontitis. However, there is a need for more documentation of this treatment modality.

Tilting of splinted implants for improved prosthodontic support: a two-dimensional finite element analysis.

Statement Of Problem: Presence of the maxillary sinus or the mental foramen may prevent implant treatment in the posterior maxilla or mandible. Tilting of distal implants supporting fixed restorations may be a valid treatment alternative.

Purpose: The aim of this study was to evaluate if tilting of splinted implants affects stress distribution in the bone surrounding the implant cervix, and to investigate if the use of tilted implants as distal abutments is biomechanically superior to the use of distal cantilevers.

Immediate and early function of implants placed in extraction sockets of maxillary infected teeth: a pilot study.

Statement Of Problem: Infection in tooth extraction sites has traditionally been considered an indication to postpone implant placement until the infection has been resolved.

Purpose: The aim of this study was to evaluate the survival rate of immediate and early-loaded implants placed immediately after extraction of teeth with endodontic and periodontal lesions or root fracture in the maxilla.

Material And Methods: Thirty-three patients with teeth judged to be unrestorable because of endodontic or periodontal lesions or root fracture were included in the study.

Short implants placed one-stage in maxillae and mandibles: a retrospective clinical study with 1 to 9 years of follow-up.

Background: The use of short implants (7-8.5 mm) has historically been associated with lower survival rates than for longer implants. However, recent clinical studies indicate that short implants may support most prosthetic restorations quite adequately, but still clinical documentation is sparse.

Immediate function with the zygomatic implant: a graftless solution for the patient with mild to advanced atrophy of the maxilla.

Purpose: In many edentulous maxillae, posterior alveolar atrophy calls for bone grafting. Patient treatment acceptance is increased by eliminating grafting using tilted implants, especially the zygomatic implant in combination with immediate function. The purpose of this study was to evaluate a protocol for immediate function (within 2 hours) of 2 zygomatic and 4 standard implants (Nobel Biocare) supporting a fixed prosthesis in the completely edentulous maxilla.
