OLATE, Sergio et al. Descriptive Analyses of Osseous Repair Related to Endosseous Dental Implant Installed in Dogs with Submerged Technique in Two Evaluation Period. Int. J. Morphol. [online]. 2009, vol.27, n.2, pp. 453-458. ISSN 0717-9502. doi: 10.4067/S0717-95022009000200023.
Osseointegrated implants are a part of clinical practice in different areas of the aesthetic and functional human rehabilitation where dentistry is not an exception; being like that, dental implants are a responses to great necessity of patient with partial or total dental lost. Exist an important and crescent research in implantology, being very important to recognize the histological characteristic of the osseous repair when dental implant are installed. The aim of this research was to recognize the histological descriptive characteristic of the osseous repair in two evaluation period. The experimental model in this research was five dogs submitted to dental extraction of mandibular bilateral bicuspid. After three month were installed bilateral implants with two implants design and different load protocols. The animals' sacrifices were realized three and six weeks after implants installation. The histological evaluation was realized in a tissue of implant with submerged techniques. Was observed osseous repair characteristic for two evaluation period. For three weeks period was observed mineralized tissue in contact with implant and non mineralized connective tissue in increase from superior to inferior areas. Reparation areas were related to adjacent angiogenic phenomena. For sex weeks period, was observed a major osseous formation, change connective tissue for mineralized tissue. Was observed too matures osseous tissue with well formed Havers channel. We conclude that exist a biological sequence of osseous repair present for a two evaluation period, where in a sex weeks is observed osseous tissue with good definition, theoretically capable for stress support.
