Les implants: où, quand, comment, pourqoui?

The concept of osseointegration which means direct contact between bone and implant has provided new possibilities for implantology and a much more serious approach of the method. Implants are placed following a two phases schedule: first a surgical procedure with a sophisticated insertion of the implants and 3 to 6 months later a prosthetic procedure. Implants can be used in many applications: single tooth replacement, partial and total edentulism. Osseous grafts can be added if needed. Connected and non-connected bridges are built on implants with a tendency to use more non-connected bridges. If all the conditions of placement of the implants and of realisation of the prosthetic supra-structures are respected, there are very few complications. Implants are actually the unique possibility to give the patient fixed oral rehabilitation while preserving the remaining bone and teeth.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Marginal bone levels at Brånemark system implants used for single tooth restoration. the influence of implant design and anatomical region

In this retrospective study of Brånemark™ system oral implants, 75 consecutive patients were treated with 84 implants for single-tooth replacement from 1988 to 1993. Two implants were lost and not replaced: the first one before the abutment connection, the latter during the first year in function. The cumulative failure rate reached 2.4% during the 5-year period. Seventy-one percent of the implants were located in the incisor/canine region of both jaws. Twenty-six per cent of the implants were inserted in special presurgical or surgical conditions. The mean annual bone loss as scored on radiograph, was 0.8 mm during the first year and 0.1 mm the following years. Different implant designs were used, a more pronounced bone loss was observed for the conical implant. The present data shows that the cumulative failure rate for single Brånemark™ implants and the radiographic bone loss is similar to that found around implants used for the treatment of complete and partial edentulism.

Mandibular metastasis of neuroblastoma (Case report)

The authors present a case of neuroblastoma of which the first symptom was mandibular metastasis. They emphasize the relatively benign nature of the intrabuccal swelling. It is remarkable how well this metastasis responded to radiotherapeutic treatment. All authors are in agreement that jaw bones are a rare area of localization for neuroblastoma metastases. In 1972, Angelopoulos, in reporting such a case, surveyed the literature and found 12 cases. Chakzabart reported one case in 1975, as did Snyder. This is one more.SCOPUS: NotDefined.jinfo:eu-repo/semantics/publishe

A surgical stent for the Branemark Novum bone reduction procedure

Background: The Brånemark Novum® concept (Nobel Biocare AB, Göteborg, Sweden) was introduced to load implants immediately with a definitive fixed prosthesis in the edentulous mandible. This concept is based on the use of prefabricated templates to allow precise placement of three implants and a prefabricated bar structure for the prosthetic procedure. To obtain three-dimensional stability in these prefabricated templates, surgical bone reduction may be necessary to obtain a stable adaptation between the templates and the recipient bone site. Purpose: The aim of this work was to design a surgical stent for predictable reduction of the residual alveolar crest prior to the implant placement procedures. Materials and Methods: A predetermined alveolar crest platform based essentially on a lateral cephalometric radiographic evaluation was simulated on a cast in order to design a transparent resin surgical guide. The predictability potential of the procedure was then evaluated in 10 patients. The prosthetic outcomes were compared with those of a similar group of 10 patients treated without the presented stent by evaluating two factors, namely, the anterior dimensions of the prostheses and the required posterior adjustments of the upper bar. Results: Correlation analysis of our series suggested a good predictability potential for this procedure (r = 0.9215). The mean anterior prosthetic dimension was 32% lower and was more predictable (narrow range of 8-12 mm vs broad range of 8-21 mm) when the stent was used. Furthermore, since half as many posterior adjustments of the upper bar were required, the laboratory procedure was facilitated. Conclusion: This individualized guide allows appropriate bone reduction for obtaining a predictable surgery and prosthetic stage.SCOPUS: ar.jFLWINinfo:eu-repo/semantics/publishe
