The maxillary posterior teeth are most often the first to be lost in chronic periodontal disease. Not only does periodontal disease reduce the maxillary bone height but, as we age, the maxillary sinus expands into the alveolar ridge. This reduces the alveolar ridge height beyond that which may occur during the repair of an extraction socket and the subsequent alveolar ridge resorption. This is ...

Residual ridge resorption has been considered as an inevitable consequence after extraction of the teeth. There is a gradual loss of the alveolar bone due to the pattern of bone remodeling. In spite of the availability of newer treatment modalities like endodontic restoration and periodontic procedures for preservation of the remaining teeth they are not feasible for the patients in severe stag...

introduction: gold standard for alveolar cleft bone grafting is autogenous bone. advantage of adding the growth factors to the bone is established, so adding prf to the autogenous bone may have beneficial effects. methods:  platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. results:  autogenous bone in all (four cases) was...

Background: One of the most significant factors in the success of dental implant procedures, can be mentioned by the quality and quantity of jaw bone. The occurrence of some problems such as trauma, infection, pathological lesions and the long-term absence of teeth in patients, it causes irregularities in the jaw bone and can get bone resorption. Sever defects after trauma or tumor resection ne...

A 24-kDa protein was isolated from the outer membrane vesicles of Porphyromaonas gingivalis W50. This protein, referred to as fibroblast-activating factor (FAF), was examined for its bone-resorptive ability by the rat long-bone assay and the mouse bone marrow cell culture system. FAF resulted in a significant release of 45Ca from cultured bones, as well as the formation of tartrate-resistant ac...

C linical decision making in elderly patients is becoming increasingly challenging as our society ages. 1 Edentulism was once considered normal for anyone entering the seventh decade of life, as was so eloquently declaimed by Jaques in Shakespeare's As You Like It : " sans teeth, sans eyes, sans taste, sans everything. " 2 Today, however, preservation of the natural dentition has been so succes...

Background The goal of this study is to evaluate complication and effectiveness of alveolar ridge augmentations using a hydroxyapatite-based alloplastic bony substitute with rhBMP-2. Methods A total of 10 patients (4 males, 6 females; 58.5 ± 8.6 years) participated in this clinical research. Alveolar ridge augmentations were performed in edentulous (4 maxillary posterior, 5 mandibular posteri...

The purpose of this review was to analyze publications related to augmentation procedures using autologous onlay grafts and to evaluate the survival/success rates of implants placed in the augmented areas. An automated search was made in Medline, of clinical publications from 2002 to 2007, including at least 5 patients and with a minimum follow-up of 6 months. Ten papers were included. These su...
