Abstract

The alveolar ridge is the bone around the root portion of the tooth. Various environmental and physiological effects accompany or disassemble, influence their fullness and performance. As such, its production as well as its conservation is linked to a constant presence of the tooth. Bone resorption in the socket after dental extraction is an undesirable natural and physiological occurrence, which often makes it difficult to place a dental implant in the selected position. The use of bone grafts has the function of creating a matrix in which the coagulated blood will form and enable the healing process. Xenografts are biomaterials of animal origin, they are deproteinized totally eliminating the organic component and avoiding immunogenicity. The present study aimed to evaluate the influence of equatorial graft on the speed of technical repair as preparation for rehabilitation with osseointegrated implants. This paper presents a case report of a patient who underwent tooth extraction, with immediate placement of equine xenograft and radiographic follow-up for recent days. Bone of equine origin when reproduced in bovine origin and ovine was the one that most showed similarity with human bone tissue, in relation to visual roughness, also related to porosity. Through radiographic follow-up, it was possible to evaluate if the equine xenograft is effective in bone neoformation in the socket after extraction and grafting. Further research should be performed with computed tomography to better evaluate the efficacy of equine xenograft.
