چکیده

UNLABELLED The aim of this study is to analyze the success of extraoral osseointegrated implants used to support designed to rehabilitate craniofacial deformities. METHOD This study was based on the retrospective assessment of charts from 59 patients submitted to cancer surgery and who received 164 extraoral implants to contain facial prosthesis. RESULTS Among 164 implants, 42 were fixed in previously irradiated regions. Eight of the implants did not have osseointegration; and from these, two were fixed in irradiated bone. The result show 116 (95.1%) successfully osseointegrated implants in non-irradiated sites. The success rate among 42 implants fixed in previously irradiated bones was 40 (95.3%) osseointegrated implants. CONCLUSION The use of extraoral craniofacial implants represents a safe and effective approach to treat facial deformities as a support for the rehabilitation prosthesis. Radiotherapy treatment does not prevent osseointegration.

Integration of periorbital titanium implants in irradiated bone: case report and histologic evaluation.

Extraoral implants are used increasingly frequently in the wake of ablative tumor surgery and adjuvant radiation or chemotherapy for craniofacial rehabilitation with facial prostheses and epitheses. However, high rates of nonintegration and implant loss have been reported for extraoral implants, especially for those in the periorbital region following irradiation. This case report and correspon...

Auricular rehabilitation by means of bone grafting from the iliac crest in combination with porous extraoral implants: a case report.

BACKGROUND Maxillofacial defects caused by cancer treatment are a huge problem affecting the quality of life of patients. Some of these deformities are minimized using facial epitheses, which need some additional retention devices like glasses or skin adhesives. The use of extraoral fixtures as bone anchorage was introduced many years ago and since then many patients were rehabilitated with bet...

Purpose: Epithetic solutions in the maxillofacial region are indicated if plastic surgery reconstruction is not a valid option for an extensive defect. The purpose of this study was to examine whether the extraoral implants used provided sufficient retention to be used as anchoring aids. Materials and Methods: Between November 1999 and September 2002, 33 identical modified Ankylos implants for ...

The impact of oral implants - past and future, 1966-2042.

This paper traces the history of oral implants, beginning with their early undocumented use in the mid-1960s. Although early experimentation with the Brånemark system of osseointegration was unsuccessful, significant improvements and scrupulous documentation of the 1970s led to their general acceptance. George Zarb spearheaded their introduction into North America and application of the osseoin...

The Use of a Trephine Biopsy Needle to Obtain Autogenous Corticocancellous Bone from the Iliac Crest: A Technical Note

In the absence of adequate bone height, augmentation of the maxillary antrum prior to placement of endosseous implants is a well–-established procedure. Although there is a debate among clinicians as to which grafting materials are the most advantageous, autogenous bone is still considered by many to be the gold standard. Often patients require more graft material than is generally available fr...
