The survival of dental implants has been linked to primary stability. The aim of this study is to analyse the factors that influence the survival of dental implants placed without primary stability.
A cohort study of implants placed without primary stability was carried out between September 2011 and July 2016. All cases with registered information on the patient and surgical intervention were used. Cases that did not have a 12-month follow-up after implant placement were excluded.
Out of 2,400 analysed implants, 92 were placed without primary stability. The absence of primary stability was classified as B in 49 cases, C in 38 cases and D in 5 cases. No statistically significant influence of the patient's age, primary stability, brand, or implant size in terms of implant survival was established. A tendency towards greater early implant loss was observed in implants whose absence of primary stability was classified as C.
Poor primary stability is not statistically significant in the loss of dental implants of the characteristics studied. Any of the factors studied are related with early implant loss as a main factor. Primary stability, survival, dental implants.
牙种植体的存留与初期稳定性相关。本研究旨在分析影响未获得初期稳定性的牙种植体存留的因素。
于2011年9月至2016年7月对未获得初期稳定性的种植体进行队列研究。纳入所有有患者及手术干预登记信息的病例。排除种植后未进行12个月随访的病例。
在分析的2400颗种植体中，92颗种植时未获得初期稳定性。其中，初期稳定性缺失被分类为B级的有49例，C级的有38例，D级的有5例。就种植体存留而言，未发现患者年龄、初期稳定性、品牌或种植体尺寸有统计学意义的影响。初期稳定性缺失被分类为C级的种植体有早期种植体丢失增加的趋势。
在所研究特征的牙种植体丢失方面，初期稳定性差无统计学意义。所研究的任何因素均与以早期种植体丢失为主要因素相关。初期稳定性、存留、牙种植体。
