RESUMO

The aim of this work is to study the behavior of the castor bean alloplastic polymer bone graft on ridge preservation. The dental extraction cicatrization process is an atrophy process. There are preventive techniques for maintenance of the dimensions of the alveolar ridge. These techniques are: dental implant, guided bone regeneration, bone graft and the combination of these techniques. The technique of bone graft is based on filling the space with the biomaterial. The castor bean alloplastic polymer bone graft surpasses the alloplastic because it is of vegetable origin and shown efficient biomaterial in the odontological area. Eighteen rats had the left lateral incisor extracted and fourteen of them received castor bean alloplastic polymer bone graft in the extraction socket, forming the experimental group. These were divided in two groups with different sacrifice time, 30 and 45 days. The control group that did not receive any treatment. The last animal is the standard gold group that served as example of complete structure. The animals were killed and they had the tissue fragments removed in order to have histological analysis under optical microscopy. It was taken occlusal radiographs and lateral cefalometric radiographs in odontological films profile immediately after the extraction and after the death. The anatomical pieces were removed and processed for making of slices. It was evaluate histologically and radiographically the wound of the extraction sockets with the graft compared to physiologic repair. The result evidenced the maintenance dimension alveolar dental sockets in the groups that received castor bean alloplastic polymer bone graft. The graft technique showed to be efficient, resulting in a minimum decrease of the dimensions of the extraction sockets. In this present work the graft technique with castor bean alloplastic polymer bone graft came effective in the maintenance of the dimensions of the alveolar bone
