Dental implants are an artificial substitute for extracted or missing teeth in the oral cavity and are valuable for improving dental health and quality of life. While many studies on implants can be found, few studies examine their effects on adjacent teeth and tissues. The study aimed to examine complications of teeth adjacent to dental implants in the posterior region.
In this retrospective case-control study, clinical data of patients treated with implants in the posterior segment were extracted from the medical records in a single community dental clinic between January 9, 2010 and January 9, 2020. The patients were examined clinically and radiographically every 6 months. Data on the adjacent teeth to the dental implants were collected and divided into two groups, complications ("study group") versus no-complications ("control group"). Multivariate logistic regression analysis was performed to find a possible correlation between the complications and the variables checked, followed by checking specific variables in the complication group.
A total of 1072 patients were included in the study. There were 179 patients (16.7%) with complications in adjacent teeth, while 893 patients had no documented complications. Predisposing factors for secondary caries were smoking (OR = 2.2, CI = 1.3-3.8) and a higher number of implants (OR = 1.6, CI = 1.1-2.5). Tooth crack and tooth fracture were analyzed together and found to be related to osteoporosis (OR = 8.9, CI = 2.9-27.6), whereas males were more prone to teeth fracture (OR = 2.8, CI = 1.1-7.4). Tooth mobility was related to a higher number of implants (OR = 16.5, CI = 3.7-73.8). Further analyzing the complication group solely, there was a statistical significance for age in primary caries and tooth mobility (p = 0.045). In addition, a higher number of implants was more prevalent with tooth mobility (p = 0.002), wider implant platform was more significant with primary caries (p = 0.012), and periodontal Stage III was more prone to tooth mobility (p < 0.001). The distance between the implant and adjacent tooth was also statistically significant-close proximity with tooth mobility and high distance with dental caries (p = 0.04).
We found a relatively high rate of complications in teeth adjacent to dental implants. Secondary caries was the most common complication. Good understanding and proper position of the implants is essential to avoid adjacent teeth complications.
种植牙是口腔中缺失或拔除牙齿的人工替代品，对改善口腔健康和生活质量具有重要价值。虽然有许多关于种植牙的研究，但很少有研究关注它们对相邻牙齿和组织的影响。本研究旨在检查后牙区种植牙的相邻牙齿并发症。
在这项回顾性病例对照研究中，从一家社区牙科诊所的病历中提取了 2010 年 1 月 9 日至 2020 年 1 月 9 日期间接受后牙段种植牙治疗的患者的临床数据。每 6 个月对患者进行临床和影像学检查。收集种植牙相邻牙齿的数据，并分为两组，有并发症（“研究组”）和无并发症（“对照组”）。对可能与并发症相关的变量进行多变量逻辑回归分析，然后检查并发症组中的特定变量。
共有 1072 名患者纳入研究。179 名（16.7%）患者的相邻牙齿出现并发症，893 名患者无记录并发症。继发龋的易感因素包括吸烟（OR=2.2，CI=1.3-3.8）和植入物数量增加（OR=1.6，CI=1.1-2.5）。牙裂和牙折合并分析发现与骨质疏松症有关（OR=8.9，CI=2.9-27.6），而男性更容易发生牙折（OR=2.8，CI=1.1-7.4）。牙齿松动与植入物数量增加有关（OR=16.5，CI=3.7-73.8）。进一步单独分析并发症组，发现原发性龋和牙齿松动与年龄有关（p=0.045）。此外，牙齿松动与植入物数量增加更常见（p=0.002），种植体平台较宽与原发性龋的相关性更显著（p=0.012），牙周炎 III 期与牙齿松动更相关（p<0.001）。种植体与相邻牙齿的距离也具有统计学意义，接近与牙齿松动有关，而距离较远与龋齿有关（p=0.04）。
我们发现种植牙相邻牙齿的并发症发生率相对较高。继发龋是最常见的并发症。良好的理解和正确的植入物位置对于避免相邻牙齿并发症至关重要。
