Brief Summary
After a dental extraction, the osseous alveoli fill naturally of a blood clot which is transformed some month later into osseous tissues. Even if the alveolar walls remain intact at the end of the intervention, the healing always comes along with a physiological reduction at the level of the site. The reduction of the alveolar crests is a continuous, cumulative and inexorable phenomenon This reduction entails in the long term aesthetic and functional damages which complicate the prosthetic rehabilitation of the dental articulate. That the prosthetic rehabilitation is removable or fixed, implanto-carried or not, it is made more difficult and less comfortable for the patient. In oral surgery, certain pathologies require for their treatment the use of materials of filling generating an activity of reduction / osseous replacement ending in the formation of a physiological calcified neo-tissue. Numerous products of osseous replacement were already used to realize alveolar fillings to avoid this inevitable and strongly harmful osseous loss.The purpose of the present study is to quantify the physiological osseous loss due to the dental extraction with or without filling by a randomized study and with calibrated criteria of evaluation. The current standard of care is no filling (healing from the blood clot) and we know the consecutive osseous loss during the aging. The technique by filling with an osseous substitute is more and more used in Europe and in Asia because of the decrease of the osseous loss. At first, these substitutes were constituted by bone grafts (autografts, allografts, xenografts) that tend to be replaced by synthetic materials. To realize these fillings according to countries, various materials are used (bovine bone, coral, bio glasses, phosphates of calcium). The most used synthetic materials are calcium ortho phosphates, the composition of which is close to mineral phases of calcified tissues. Ceramic of phosphate of calcium and more particularly the Biphasic Phosphate Calcium (BCP) was already used in numerous clinical applications.We chose as this study MBCP gel ™, same product beforehand used in 2 clinical studies for which the Nantes University Hospital was the sponsor.The perspectives of this study are to be able to propose the systematization of the alveolar filling to be able to decrease the osseous reduction after an extraction and to be able to propose more functional prosthetic rehabilitation (improvement of the masticatory power), more aesthetic and comfortable. When we know the effect of the under nutrition due to masticator difficulties notably at the aged persons, we measure all the importance of this major problem of Public health.
