Introduction The use of dental implants provides a revolutionary solution to the problem of missing teeth in the oral cavity. The aim of this study was to assess the early implant survival rate in relation to implant diameter and site of placement. Methods The data were collected from 186 patients treated between January 2019 and June 2021. All the implants were evaluated and restored after three months of implant placement. The early implant survival was calculated for different implant diameters with the odds ratio (OR). Results A total of 373 implants were placed. Implants were placed in the following areas: upper posterior area (UPA), n = 123, upper anterior area (UAA), n = 49, lower posterior area (LPA), n = 184, and lower anterior area (LAA), n = 17. Implants of the following diameters were placed: 3.5 mm (n = 129), 4.3 mm (n = 166), and 5 mm (n = 78). The overall early survival rate was 97.32% after three months of placement. The highest early survival rate was at LAA (100%) and the lowest early survival rate was at UAA (95.9%). The implants 5 mm in diameter had the highest early survival rate (98.72%), while the implants 3.5 mm in diameter had the lowest early survival rate (94.57%). The ORs of the early implant survival were 4.7 [95% confidence interval (CI): 0.96-23.05)] and 4.42 (95% CI: 0.53-36.61) for the 4.3 mm and 5 mm implants, respectively, with no statistical significance. Conclusions The implants placed in the oral cavity had acceptable survival rates regardless of implant diameter or site of placement.
引言 牙种植体的使用为口腔内牙齿缺失问题提供了一种革命性的解决方案。本研究的目的是评估与种植体直径和植入部位相关的早期种植体存活率。方法 收集了2019年1月至2021年6月期间接受治疗的186例患者的数据。所有种植体在植入三个月后进行评估和修复。采用比值比（OR）计算不同种植体直径的早期种植体存活率。结果 共植入373枚种植体。种植体植入以下区域：上颌后牙区（UPA），n = 123；上颌前牙区（UAA），n = 49；下颌后牙区（LPA），n = 184；下颌前牙区（LAA），n = 17。植入的种植体直径如下：3.5 mm（n = 129）、4.3 mm（n = 166）和5 mm（n = 78）。植入三个月后的总体早期存活率为97.32%。早期存活率最高的是LAA（100%），最低的是UAA（95.9%）。直径5 mm的种植体早期存活率最高（98.72%），而直径3.5 mm的种植体早期存活率最低（94.57%）。4.3 mm和5 mm种植体早期种植体存活的OR分别为4.7 [95%置信区间（CI）：0.96 - 23.05]和4.42（95% CI：0.53 - 36.61），无统计学意义。结论 无论种植体直径或植入部位如何，口腔内植入的种植体均具有可接受的存活率。
