» Prosthodontic Implant Rehabilitation After the Treatment of a Pathologic Lesion in the Mandible: A Case Report

A case is reported of an extensive ossifying fibroma involving the mandible and its successful rehabilitation by using an osseointegrated implant. The lesion was enucleated under general anesthesia along with involved teeth Nos. 35, 36, 37, and 38. Regular radiographic follow-up showed complete bone healing within the period of two years. A free-end saddle removable partial denture was avoided by the appropriate use of root-form implants.
» The Adaptation of Implant-Supported Superstructures to the Alveolar Crest: A Follow-Up of 49 Cases

A prospective clinical and radiographic study has been carried out in 49 patients with a total of 252 implants. In a mixture of 17 edentulous mandibles, 20 edentulous maxillas, nine partial edentulous cases, and three single-tooth cases, prosthetic treatments were aimed at getting as close an adaptation as possible between gingival tissues and superstructure. The shortest possible abutments were used, and the implants were surgically positioned subcrestally. The results during a 5-year follow-up showed a success rate of 98.9% for fixtures in the lower jaw and 96.3% for the upper jaw with a total success rate of 97.3%. The marginal bone reduction during five years with closely adapted superstructures was 0.11 mm in the mandible and 1.1 mm in the maxilla. Our results support the use of close gingivally adapted superstructures, although oral hygiene controls and instructions are regularly advisable.
» Complications After Maxillary Sinus Augmentation: A Case Report
By JDI editor | Published 04/3/2009| Dental Implant 3| Unrated

The maxillary sinus grafting procedure has been routinely performed with predictable results. The procedure has proven to be an acceptable modality for bone augmentation to provide a base for endosseous implant placement. Several complications have been documented in the literature. They vary from sinus membrane perforation to formation of a mucocele inside the bony graft mass. This report describes a serious complication after a maxillary sinus augmentation that resulted in obliteration of the sinus.
» Computer Analysis of Titanium Implants in Atrophic Arch and Poor Quality Bone: A Case Report
By JDI editor | Published 04/1/2009| Dental Implant 3| Unrated

Private Practice, Dormagen, Germany.

The oral implantologist usually uses a panoramic radiograph for the evaluation of bone tissue around implants. The development of computed tomography combined with computer software has allowed for the bone-to-implant interface to be illustrated in greater detail with cross-sectional and pseudo-color images. An implant patient has titanium fixtures in an atrophic arch and poor quality bone four years after implantation. The implants were loaded with fixed metal/resin restorations seven days after surgery. Integration of the implants and the anatomic structures near the implant sites are described with an imaging technique.
» A Survey Of Clinical Members Of The Association Of Dental Implantology in the United Kingdom. Part II. The Use Of Augmentation Materials In Dental Implant Surgery

This survey shows that a wide range of materials is used in the United Kingdom for bone augmentation in relation to oral implantology, and it is reassuring that long-term survival rates for implants inserted into sites that have been augmented are high. In the first instance, there is a pressing requirement for a systematic review to be carried out with regard to the efficacy of autogenous bone and DFDB in this context. However, it remains apparent that RCTs (including clinical and histological outcomes) are required to compare the long-term success rates for implants inserted into sites grafted with different augmentation materials. Until the evidence base for augmentation materials in oral implantology is clearly established, the choice of an augmentation material will remain heavily influenced by the training, experience, and preferences of the individual clinician30 and presumably by the effects of marketing by companies that produce augmentation materials.
