Implante imediato: revisão de literatura.

Immediate implant placement in fresh extraction sockets has become a well-established approach in contemporary implant dentistry, particularly in the esthetic zone of the anterior maxilla. This study aimed to review the literature on immediate implants, addressing biological, technical, and clinical factors associated with treatment success. Classical studies and recent evidence, including systematic reviews and meta-analyses, were analyzed to better understand peri-implant tissue behavior, success predictors, and limitations of the technique. The findings indicate that although immediate implants show survival rates comparable to conventional protocols, they do not prevent physiological bone remodeling, especially of the buccal bone plate. Adjunctive strategies such as proper three-dimensional implant positioning, use of biomaterials, connective tissue grafts, and immediate provisionalization play a key role in achieving predictable esthetic outcomes. It can be concluded that the success of immediate implants depends on careful case selection, multidisciplinary planning, and technical expertise, making it a reliable treatment option when properly indicated.
