The palatal subepithelial connective tissue flap method for soft tissue management to cover maxillary defects: a clinical report.

This article presents a technique for soft tissue reconstruction and covering defects associated with maxillary implant-supported restorations. A pedicle subepithelial connective tissue flap is prepared from the palatal mucosa near the area to be treated and is displaced into the receptor site. The donor site remains primarily covered. An increase in soft tissue volume is achieved at the receptor site, which is advantageous for various reasons. The pedicle graft has been used for different indications: closure of the alveolus after immediate implant placement, papilla reconstruction, defect and dehiscence repair, and multiple-layer closures after bone grafting and treatment of peri-implantitis. Over a 32-month period, 103 patients were treated with this method. Partial flap necrosis occurred in only 2 patients. All other patients showed significant improvement over the preoperative condition.

Soft tissue management in oral implantology: a review of surgical techniques for shaping an esthetic and functional peri-implant soft tissue structure.

Along with osseointegration and restoration of function, the patient's subjective satisfaction with the esthetic result is a touchstone of the success of implant therapy. Although esthetic restoration of natural teeth can be achieved routinely through appropriate tooth preparation and a natural-looking design on the part of the dental laboratory, the road to success is much more complicated with implants, because of atrophy of bone and mucosa. Surgical techniques, paths of incision, and useful instruments for implant therapy are described, from implant placement to exposure. These methods help to provide durable, functional, and esthetic results.

[Mesothelioma--asbestos in Lebanon: a problem to be considered].

To estimate the incidence of pleural mesothelioma and its relationship with the occupational and environmental exposure to asbestos in Chekka region. Between 1991 and 2000, 22 cases of malignant mesothelioma were diagnosed at Hôtel-Dieu de France Hospital. Eighteen cases were epidemiologically investigated. Fifteen among these 18 patients (83%) had a positive exposure history: exposure was occupational in 11 cases and environmental in 4 cases. The tumor was attributable to Eternit Company in 12 cases among the exposed 15 (80%). These 12 cases were secondary to occupational exposures in 8 and to environmental exposure in 4 cases. Mean latency period between exposition and diagnosis was 29 years. Fifteen patients died from the progression of their disease after a median survival of 8 months. The relationship between pleural mesothelioma and Eternit Company with the related occupational and environmental risk in Chekka region is obvious. The assessment of the incidence needs a national cancer registry. Despite the protective measures taken by the government since 1996, an increase in the incidence is suspected in the coming ten years because of the long latency period of the disease.

[Maxillary antrum surgery with or without bone lid formation. Retrospective comparative study].

A long-term study was performed after conservative maxillary antrum surgery with (50) and without (106) bone lid formation including a total of 154 patients. While no differences were found regarding the patients' sensitivity to changes in the weather, neurological disorders, or complaints of pressure sensations, considerably better results were obtained with respect of the time until a stable postoperative condition was achieved, the radiographic and the local findings, after surgery with the use of a bone lid.
