Avaliação do enxerto ósseo autógeno e estudo da osseointegração de implantes nos períodos de incorporação e maturação óssea em áreas submetidas a cirurgia de enxerto ósseo em elevação de seio maxilar

Abstract

The implantology in order to provide better aesthetic and functional results, presented numerous innovations and technologies to achieve these goals associated with reduced treatment time. However patients who have the need for reconstructive surgery associated with bone grafts seeking the proper installation of these implants remain as challenges. Thus, this work presents two studies described in the following chapters. Article I: Histological analysis of existing resources in the process of development and maturation in areas prone to bone graft surgery in sinus floor elevation. It was observed in both periods analyzed, bone repair, which were similar in both the periods. Thus, it can be concluded that autogenous grafts has similar characteristics in the incorporation phase (2 months) and mature (6 months), allowing the tissue manipulation in the initial stage without their involvement. Article II: The objective of this chapter was to evaluate the osseointegration in two different periods being, incorporation (2 months) and maturity (6 months) bone in areas subjected to bone graft surgery in sinus floor elevation and stability of the installed prosthesis. It was observed in both study periods, the bone ingrowth (2 months) and maturation (6 months), although at different stages of bone healing that showed similar results for bone integration and stability of the prosthesis. Thus, it can be concluded that the insertion of dental implants in these regions in the shortest repair, namely on bone growth phase (2 months) does not jeopardize the osseointegration or long-term stability of the prosthesis. The reduction in the treatment of patients undergoing reconstructive surgery with bone grafting time in sinus floor elevation is possible to perform the installation of implants in bone growth period.
