A core was obtained from 17 sockets prior to implant placement for histomorphometry at 5 to 6 months postextraction. Radiographic analysis during the same postextraction healing period showed radiopaque tissue in all sockets.

Extra oral cementation of implant prosthesis: a case report.

Extraoral cementation is a technique that utilizes a stock abutment and a laboratory fabricated crown that is cemented extra orally; the advantage of this technique is that the retained excess luting agent during intraoral cementation, which can be a source of bacterial retention and cannot be observed radio graphically and is not possible to remove with explorer all the time, does not get accumulated and can be trimmed off easily before the final placement of the crown. Thus this technique allows no retention of luting cement, providing better soft tissue contours, no soft tissue inflammation, no retention of plaque and no bone loss. In short it prevents implant failure related to retained cement around implants.

Peri-implant and periodontal tissues: a review of differences and similarities.

The health and vitality of an osseointegrated implant depends on the surrounding supporting tissues, which not only anchor the implant to the bone but also have the important function of providing a protective seal. The aim of this article is to provide a basic understanding of differences and similarities between the periodontal and peri-implant tissues at the histologic, clinical, and immunologic levels; it is essential to know these differences and similarities during the clinical handling of these similar-looking tissues. The comparative features are of clinical relevance because it is critical to understand the behavior of the soft tissue found around the tooth and implant.

Alveolar ridge preservation with the socket-plug technique utilizing an alloplastic putty bone substitute or a particulate xenograft: a histological pilot study.

Following tooth extraction, ridge preservation procedures are employed to regenerate bone in the extraction socket, limit consequent ridge resorption, and provide a stable base for implant placement. The purpose of this study is to histologically evaluate and compare bone regeneration in extraction sockets grafted with either a putty alloplastic bone substitute or particulate anorganic bovine xenograft utilizing the socket-plug technique. Nineteen patients underwent 20 tooth extractions and ridge preservation following a standardized protocol.

Socket preservation with alloplast: discussion and a descriptive case.

Soon after tooth extraction the bone resorption takes place reducing the height and width of alveolar ridge. This produces an altered morphology of the bone unfavorable for implant placement and implant placement becomes impossible without surgical correction. Socket grafting maintains and preserves ridge for implant placement.

Socket grafting with calcium phosphosilicate alloplast putty: a histomorphometric evaluation.

Background: Socket grafting with a bone graft substitute immediately after extraction is essential to preserve the ridge architecture for implant placement. Several bone graft substitutes have been tested for their ability to effectively regenerate osseous tissue in the sockets. Evidence suggests that socket bone typically regenerates during a period of 6 to 8 months or longer, depending on several factors including the original ridge dimensions, type of graft, and the overall systemic health of the individual.

Improving oral rehabilitation through the preservation of the tissues through alveolar preservation.

When performing a tooth extraction, imminent collapse of the tissue by resorption and remodeling of the socket is a natural occurrence. The procedure for the preservation of the alveolar ridge has been widely described in the dental literatures and aims to maintain hard and soft tissues in the extraction site for optimal rehabilitation either with conventional fixed or removable prosthetics or implant-supported prosthesis.
