To analyze the fracture resistance of zirconia implants within the anterior region and evaluate whether zirconia-zirconia implants can be a viable alternative to titanium implants.
Four online databases (Cochrane Library, Ovid, PubMed, and Scopus) were searched for the period of January 2011 to July 2021. All studies that analyzed the in vivo clinical outcome of two-piece implants in the anterior region in English language were included.
The search strategy identified 242 studies. Of these studies, three studies were included for qualitative synthesis based on the pre-determined eligibility criteria. The results showed that there is significant difference in biological results, fractal behavior and other complications between one-piece and two-piece zirconia implants. Two-piece zirconia implants demonstrated favorable longevity and success rates within anterior maxillary in short-term trials.
Although factors involved in fractures have been identified-sandblasting, implant diameter, occlusal load, age and implant coating-there is limited quantitative assessment to gauge the fracture resistance of two-piece zirconia implants. Hence, further research with long-term clinical evidence is required.
分析前牙区氧化锆种植体的抗折性能，并评估氧化锆-氧化锆种植体是否可作为钛种植体的可行替代方案。
检索了四个在线数据库（Cochrane图书馆、Ovid、PubMed和Scopus），检索时间为2011年1月至2021年7月。纳入所有分析前牙区两件式种植体体内临床结果的英文研究。
检索策略共识别出242项研究。其中，三项研究根据预先确定的纳入标准被纳入定性分析。结果表明，一体式和两件式氧化锆种植体在生物学结果、分形行为和其他并发症方面存在显著差异。在短期试验中，两件式氧化锆种植体在上颌前部显示出良好的长期效果和成功率。
虽然已经确定了与骨折相关的因素——喷砂、种植体直径、咬合负荷、年龄和种植体涂层——但对两件式氧化锆种植体抗折性能的定量评估有限。因此，需要进一步开展具有长期临床证据的研究。
