Nowadays, patients find much information on dental treatment from the Internet. There is a vast amount of information on dental implants, in contrast to the limited information available on natural teeth. This review addresses research on survival of natural teeth and dental implants, and discusses factors affecting the survival rate of implants, as well as certain dogmas in implant dentistry. To simplify treatment planning, the article presents a classification system in which teeth are classified as secure, doubtful, or irrational to treat. Secure teeth should last for a long period of time without need for complex treatment. Doubtful teeth are teeth that might need complicated treatment and additional maintenance in order to be maintained. Teeth irrational to treat are teeth that cannot be saved and for which extraction is the only treatment option. Multiple risk factors might decrease the survival probability of teeth. The survival and success rates of dental implants will never succeed the survival rates of healthy, clean teeth. Dental implants and implant-supported restorations are an excellent treatment modality, but it must always be kept in mind that it is associated with a risk of biological and technical complications. Implants are supposed to replace missing teeth - they are not supposed to replace teeth.
如今，患者可从互联网上获取大量有关牙科治疗的信息。与天然牙有限的信息相比，种植牙方面的信息海量。本综述探讨了天然牙和种植牙留存情况的研究，讨论了影响种植体留存率的因素以及种植牙科学中的某些教条。为简化治疗计划，本文提出一种分类系统，将牙齿分为治疗安全、存疑或不合理三类。安全的牙齿应能长期留存，无需复杂治疗。存疑的牙齿可能需要复杂治疗和额外维护才能留存。治疗不合理的牙齿是无法保留的牙齿，拔牙是唯一的治疗选择。多种风险因素可能会降低牙齿的留存概率。种植牙及其支持的修复体的留存率和成功率永远无法超过健康、清洁牙齿的留存率。种植牙和种植支持式修复体是一种出色的治疗方式，但必须始终牢记，它们存在生物和技术并发症的风险。种植体旨在替代缺失牙——而不是替代牙齿。
