The aim of this study was to carry out a bibliographic review of all available literature addressing the issue of whether or not the connection of teeth to implants by means of a prosthesis is a viable treatment alternative. Twenty articles from a variety of sources were analyzed and classified in order to draw conclusions. Articles were classified by type and an analysis was made of the different variables considered in each study, obtaining percentages of implant survival ranging from 84.4% to 100%, prosthetic complications ranging from 80% to 90%, and the incidence of dental intrusion ranging from 0 to 5.6%. Biomechanical studies: Some articles studied models in order to assess different connections subjected to force, in which varying results were obtained. Rigid connections appeared to produce the most stress to the natural tooth, periodontal ligament and peri-implant bone; non-rigid connections reduced the stress to the bone, but increased stress to the prosthesis.
The results obtained were disparate. Studies in the medium or short-term show this as a viable treatment alternative, whereas some studies point to a greater risk of complications, although the use of rigid connection decreases the percentage of intrusion. Other bibliographic reviews have concluded that there is a need for more longitudinal studies on the viability of tooth-implant connection, also concluding that complications are greater when this is the chosen treatment. As a viable alternative with an acceptable success rate, this course of treatment is always associated with rigid connection rather than non-rigid connection. Although intrusion is avoided with rigid connection, this nevertheless remains inadvisable as the primary treatment choice.
对所有关于通过义齿将牙齿与种植体连接是否可行的文献进行综述。
分析并分类了来自不同来源的 20 篇文章，以得出结论。文章按类型分类，并对每项研究中考虑的不同变量进行了分析，得出的种植体存活率从 84.4%到 100%不等，修复体并发症从 80%到 90%不等，牙齿侵入的发生率从 0 到 5.6%不等。生物力学研究：一些文章研究了模型，以评估不同连接在受力时的情况，结果有所不同。刚性连接似乎对天然牙、牙周韧带和种植周骨产生最大的应力；非刚性连接减少了对骨的应力，但增加了对修复体的应力。
结果各不相同。中期或短期的研究表明这是一种可行的治疗选择，而一些研究指出存在更大的并发症风险，尽管刚性连接减少了侵入的百分比。其他文献综述得出的结论是，需要进行更多关于牙齿-种植体连接可行性的纵向研究，并得出结论认为，当选择这种治疗方法时，并发症更多。作为一种可行的替代方法，具有可接受的成功率，这种治疗方法始终与刚性连接相关，而不是非刚性连接。尽管刚性连接可以避免侵入，但作为主要治疗选择仍然是不可取的。
