Fatores predisponentes da perda óssea primária ao redor de implantes dentários: um estudo clínico observacional descritivo

Abstract

Controlled implant therapy has proven to be a reliable treatment option for single, multiple and total edentulism. There is a wide range of implant systems available, with different macro and microscopic characteristics. The long-term survival rates of the implants have being experienced as excellent. Despite advances in implant dentistry, marginal bone loss occurs in all types of implants associated with different causal factors. This initial bone loss can result in implant surface exposure and, consequently, implant surface colonization. Bone loss also affects the gingival contour. This study aims to identify the predictive variables of peri- implant bone loss, through longitudinal clinical follow-up, evaluating the influence of brands, installation times, relationship between the platform and the bone crest, insertion torque, patient's oral condition, type of load and presence of parafunction or negative habits. The results show out that the loading moment of the implants, being immediate, can be considered a predisposing variable for less primary bone loss compared to late implants.
