Simple preservation of a maxillary extraction socket using beta-tricalcium phosphate with type I collagen: preliminary clinical and histomorphometric observations.

Alveolar atrophy following tooth extraction remains a challenge for future dental implant placement. Immediate implant placement and postextraction alveolar preservation are 2 methods that are used to prevent significant postextraction bone loss. In this article, we report the management of a maxillary tooth extraction socket using an alveolar preservation technique involving placement of a cone of beta-tricalcium phosphate (beta -TCP) combined with type I collagen without the use of barrier membranes or flap surgery.

Maxillary sinus floor augmentation: comparing osteotome with lateral window immediate and delayed implant placements. An interim report.

Objective: A retrospective study was performed to observe clinical outcomes of dental implants placed in augmented maxillary sinuses using an osteotome or a lateral approach technique with synchronous or delayed implant placement.

Study Design: A total of 61 patients were enrolled in the study. The distribution and frequency of sinus augmentation techniques and implant placements were evaluated according to the implant site and Cawood-Howell classifications.

[Preimplant preparation of the extraction alveolus with the deproteinized bovine bone and calcium-sulphate].

Background: Different materials are used to prevent the resorption of alveolar bone. The aim of this report was to show the radiographical and histological results prior to implant insertion, when a deproteinized bovine bone mineral (BioOss) and calcium-sulphate were placed into the extraction socket immediatelly after the tooth removal.

Case Report: A 22-year-old woman was scheduled for the removal of the second lower molar when the extraction socket was filled with BioOss covered with calcium-sulphate as a resorbable membrane.
