摘要:

目的 探讨窄直径种植体植入后早期失败情况,为临床牙种植修复提供参考。方法 对2017年4月至2020年4月于某口腔医院种植科因牙列缺损行Straumann 3.3 mm窄直径种植体种植修复的725例患者(男性353例,女性372例)植入的1 001颗窄直径种植体的早期失败进行回顾性分析。采用单因素和多因素广义估计方程分析年龄、性别、种植位点、植体材料、表面处理、长度、骨增量与否、愈合方式等因素与窄直径种植体早期失败的相关性。结果 725例患者中早期失败34例,共计38颗窄直径种植体,窄直径种植体的早期失败率在患者水平为4.69%,种植体水平为3.80%。不同年龄、性别、植体材料、表面处理、长度、愈合方式之间的窄直径种植体早期失败率差异无统计学意义(P>0.05)。单因素分析结果显示:种植体水平,上颌前牙区失败率为2.16%,显著低于下颌前牙区的失败率8.64%(P<0.001);上颌前牙区失败率与后牙区失败率3.35%差异无统计学意义(P>0.05)。此外,在前牙区,窄直径种植体植入同期行骨增量组的早期失败率显著低于未进行骨增量组(P<0.05)。然而,多因素广义估计方程分析结果表明窄直径种植体早期失败率仅与下颌前牙区呈显著正相关(P<0.01)。结论 Straumann 3.3 mm窄直径种植体早期总体存活率大于95%, 在下颌前牙区的早期失败率显著高于上颌前牙区及后牙区。

Abstract:

Objective To explore the early failure of narrow-diameter implants (NDIs) and to provide a reference for clinical implant restoration. Methods From April 2017 to April 2020, data from a total of 725 patients (with 1 001 NDIs) who accepted implant restoration due to dentition defects were collected from the department of dental implantology in a stomatological hospital; 353 males and 372 females were included. The early failure rate of 1 001 NDIs was retrospectively analyzed. Univariate generalized estimated equation (GEE) and multivariate GEE were used to explore risk factors, including age, sex, implant location, materials, surface modification, length, bone augmentation and healing procedure, associated with early failure of NDIs. Results There were 34 cases of early failure among 725 patients, including 38 NDIs. The early failure rate of NDIs was 4.69% at the patient level and 3.80% at the implant level. There was no significant difference in the early failure rate of NDIs among different age groups, sexes, implant materials, surface modifications, lengths, and healing procedures (P>0.05). Univariate analysis showed that there was a significant difference between the early failure rate of NDIs in the anterior maxilla group (2.16%) and the anterior mandible group (8.64%) at the implant level (P<0.001). However, there was no significant difference in the early failure rate between the anterior maxilla group and the posterior group (3.35%) (P>0.05). In addition, in the anterior region, the early failure rate of NDIs in the group with simultaneous bone augmentation was significantly lower than that of the group without bone augmentation (P<0.05). However, multivariate GEE analysis showed that the early failure rate of NDIs was only significantly positively correlated with implants in the mandibular anterior region (P<0.01). Conclusion The overall early survival rate of Straumann 3.3 mm NDIs is greater than 95%. The early failure of NDIs in the anterior mandible region is much higher than that in the anterior maxilla region and posterior region.
