RESUMO
Between 1987 and 1990, 57 edentulous patients were treated with overdentures supported by 2 endosseous IMZ implants connected by a bar in the lower jaw. The condition of the peri-implant tissue was evaluated for a loading period ranging from 12 to 57 months (mean 30 months and median 24 months). The evaluation parameters included Plaque Index, Bleeding Index, Gingiva Index, pocket depth, dysesthesia of chin or lip, peri-implant bone loss and loss of implants. During the healing phase prior to the construction of an overdenture, 3 implants were lost. After a healing period of 6 months, these implants were successfully replaced. During the follow-up period, a Plaque Index < or = 1 was observed in 45 patients and an abundance of plaque and calculus was observed in 1 patient. Heavy or profuse bleeding and severe gingival inflammation was observed in 3 patients. The mean pocket depth was 3.6 +/- 1.7 mm. None of the patients experienced lip or chin dysesthesia. Marginal bone loss was observed around 30 (26%) implants. From this study it is concluded that, once proper osseointegration is obtained, 2 IMZ implants connected with a bar in the lower jaw supply a proper base for the support of an overdenture; the condition of the peri-implant tissues is steady and independent of the follow-up time.

Placement of endosseous implants in the atrophic maxilla is often restricted because of lack of supporting bone. In this article, experience with augmentation of the maxillary sinus floor with autogenous bone grafts to enable insertion of endosseous implants is described. The technique is aimed at providing a cortical layer on top of the graft to ensure a reliable seal of the maxillary sinus and to achieve optimal stability of the bone graft in case of simultaneously placement of dental implants. The procedure was used in 25 patients, using iliac crest grafts (22 patients, 86 implants), symphyseal bone grafts (two patients, six implants), or a maxillary tuberosity bone graft (one patient, one implant). Ninety-three Brånemark implants (Nobelpharma, Götenburg, Sweden) were inserted in 47 grafted maxillary sinuses. The mean follow-up was 16 months (range, 6 to 36 months). No inflammation of the bone grafts nor of the maxillary sinus occurred. The sinus membrane was perforated accidentally in eight cases during the surgical procedure. Five implants (5.4%), all inserted in iliac crest grafts, were lost during the healing period. The patients received implant supported overdentures (16 patients) or bone-anchored bridges (nine patients). From this preliminary study it is concluded that augmentation of the maxillary sinus floor with bone grafts for the insertion of endosseous implants is a promising solution for patients with atrophic maxillae and functional problems with their partial or full dentures.

Two cases of pemphigus vulgaris in which oral lesions were the first signs of the disease are reported. The clinical signs and symptoms, histologic characteristics, and immunohistochemistry are discussed. Early recognition of oral lesions associated with the disease is of the utmost prognostic value. Treatment, which can only be symptomatic, usually consists of a combination of a corticosteroid and immunosuppressive medication. Because side effects may be serious, these medications should be prescribed and monitored by an experienced dermatologist.

An attached and keratinized mucosa is often preferable or necessary around the abutments of dental implants. This can be created by means of a free mucosal graft from the hard palate. A simple method to achieve this situation is described.

In case of an unsuccessful endodontic treatment apicectomy often may cure the periapical inflammation. If for technical reasons periapical surgery is not possible, many of these teeth can be preserved by means of intentional replantation. The indications and contra-indications, the technical procedure and two case histories are described.
