Implant fracture is an infrequent and late biomechanical complication with a serious clinical outcome. In effect, such fractures pose important problems for both the patient and the dental surgeon. According to most literature sources, the prevalence of dental implant fractures is very low (approximately 2 fractures per 1000 implants in the mouth). Considering that implant placement is becoming increasingly popular, an increase in the number of failures due to late fractures is to be expected. Clearly, careful treatment can contribute to reduce the incidence of fracture. An early diagnosis of the signs alerting to implant fatigue, such as loosening, torsion or fracture of the post screws and prosthetic ceramic fracture, can help prevent an undesirable outcome. The present literature review describes the management options and discusses the possible causal mechanisms underlying such failures, as well as the factors believed to contribute to implant fracture.
种植体骨折是一种罕见且迟发的生物力学并发症，具有严重的临床后果。实际上，这种骨折会给患者和牙医带来重大问题。根据大多数文献资料，牙种植体骨折的发生率非常低（大约每 1000 个植入物中有 2 个骨折）。考虑到种植体的应用越来越普及，预计由于迟发性骨折导致的失败数量将会增加。显然，仔细的治疗可以有助于降低骨折的发生率。早期诊断种植体疲劳的迹象，如松动、扭转或种植体螺丝和修复体陶瓷断裂，有助于预防不良后果。本文复习了相关文献，描述了处理方案，并讨论了导致这些失败的可能的因果机制，以及被认为会导致种植体骨折的因素。
