Implant therapy aims at providing the patient with a functional and esthetically pleasing rehabilitation in a long-term perspective. The loss of an implant constitutes a major complication, which may have an impact on the treatment plan and/or jeopardize the longevity of the restoration. Implant loss may occur during the phase of osseointegration (early) or at a later time when the previously achieved osseointegration is lost (late). The present work evaluates the evidence on the occurrence of both events and discusses etiology, risk factors, and consequences.

种植体丢失的病因、发生和后果

植入治疗旨在从长远的角度为患者提供功能性和美学上令人愉悦的康复。种植体的丢失是一种主要的并发症，可能会影响治疗计划和/或危及修复体的寿命。植入物丢失可能发生在骨整合阶段（早期）或在先前实现的骨整合丢失（晚期）的后期。目前的工作评估了这两种事件发生的证据，并讨论了病因、风险因素和后果。
