Maxillary sinus and ridge augmentation were performed using the allograft cellular matrix containing live stem cells (Osteocel)*. The results were evaluated via a postoperative Cone Beam Computer Tomography (CBCT) scans and periepical radiographs. The sinus augmentation case was evaluated in 10 weeks in which the radiographic bone tomography was similar to that of the native bone. The ridge aug...

BACKGROUND Guided bone regeneration (GBR) is a widely used procedure for augmenting alveolar ridge width prior to placement of endosseous implants. Various graft materials and barrier membranes (non-resorbable and bioabsorbable) have been used in GBR. The aim of this study was to assess the performance of a new bioabsorbable, synthetic polyglycolic acid/trimethylene carbonate (PGA/TMC) barrier ...

Installation of dental implants is often hindered by compromised alveolar ridge which requires augmentation. Several methods including autogenous bone graft, guided bone regeneration, and distraction osteogenesis are implied to restore the compromised alveolar ridge. This chapter reviews treatment modalities and techniques of alveolar ridge augmentation. Recent development and updates in this f...

Key Clinical Message The continuing resorption of the alveolar ridge will eventually result in insufficient bone height superior to the IAN, making dental implant placement impossible. The augmentation procedure above the IAN in terms of height provides sufficient bone for implant placement and allows long-term successful restoration of missing teeth with implant-supported prosthesis.

In the maxillary anterior region, reconstruction of the localized alveolar ridge defect is very important in enhancing the esthetics of fixed partial denture. A 40-year-old female patient presented with a chief complaint of the inconvenience and unesthetic problem of 3-unit maxillary anterior prosthesis due to alveolar ridge resorption. After removal of old prosthesis, intraoral examination rev...

This case report demonstrates a two-...

The maxillary posterior area is the most challenging site for the dental implant. Although the sinus graft is a predictable and successful technique for rehabilitation of atrophic and pneumatized posterior maxilla, when there is severe destruction of alveolar bone, a very long crown length remains challenging after successful dental implants installation with sinus graft. We performed vertical ...

The goal of all prosthetic treatment is to obtain a satisfying functional and esthetical oral status. In a fixed bridge, the pontic frequently give the impression that they rest on the top of the ridge rather than emerge from within the alveolar process & lack marginal gingiva & interdental papillae. Black triangles, which almost always interfere with dentofacial esthetics, are present in the e...

Measurements of seafloor asymmetry at about 360000 pairs of conjugate points along 1250 profiles across the midAtlantic Ridge (MAR) provide new constraints on models for the upwelling of the buoyant asthenosphere. The sign and amplitude of the asymmetry vary systematically and are functions of the distance between the spreading center and the location of the inferred location of maximum regiona...
