Abstract

Although vertical guided bone regeneration (v-GBR) is a popular technique for treating alveolar bone deficiency, there are no long-term studies analyzing the longevity and success of the results. This retrospective study analyzes the clinical and radiographic outcomes of oxidized implants placed after v-GBR, with a follow-up period of 4 to 15 years. The study considers 41 v-GBR patients receiving one or more dental implants between 2001 and 2013 (115 implants total). Clinical and radiographic outcomes were recorded during follow-up visits. A multiple logistic regression model was used to analyze the correlation between peri-implantitis and demographic, surgical, and clinical variables, as well as the length of the follow-up period. The cumulative survival rate of the implants over the mean follow-up period of 9.6 ± 3.4 years was 95.7%, with peri-implantitis observed in 26.1% of the implants. The variables that correlated with the occurrence of peri-implantitis were smoking (OR = 8.5, 95% CI = 1.6 to 44.5, P < .01), posterior mandible implant position (OR = 2.1, 95% CI = 1.2 to 3.9, P < .01), and the length of the follow-up period (OR = 1.5, 95% CI = 1.1 to 2.2, P < .01). In this study, smoking, time since the surgery, and the implant position were associated with peri-implantitis developing on rough surface implants. Along with with previous long-term follow-up studies, this suggests that oxidized surface implants have a higher risk of peri-implantitis than machined ones.

粗糙种植体垂直增强骨:一项4至15年随访的回顾性研究
虽然垂直引导骨再生(v-GBR)是治疗牙槽骨缺乏的一种常用技术,但目前还没有长期的研究分析结果的寿命和成功率。本回顾性研究分析了v-GBR术后放置氧化植入物的临床和影像学结果,随访时间为4至15年。该研究考虑了2001年至2013年间接受一次或多次种植牙的41例v-GBR患者(总共115例种植牙)。在随访期间记录临床和影像学结果。采用多元logistic回归模型分析种植体周围炎与人口统计学、外科和临床变量以及随访时间的相关性。在平均9.6±3.4年的随访期间,种植体的累计存活率为95.7%,26.1%的种植体出现种植体周围炎。与种植体周围炎发生相关的变量为吸烟(OR = 8.5, 95% CI = 1.6 ~ 44.5, P < 0.01)、后下颌种植体位置(OR = 2.1, 95% CI = 1.2 ~ 3.9, P < 0.01)、随访时间(OR = 1.5, 95% CI = 1.1 ~ 2.2, P < 0.01)。在本研究中,吸烟、手术后时间和种植体位置与种植体周围炎在粗糙表面种植体上发生有关。与之前的长期随访研究一起,这表明氧化表面种植体比机械种植体有更高的种植体周围炎风险。

期刊介绍: The International Journal of Periodontics & Restorative Dentistry will publish manuscripts concerned with all aspects of clinical periodontology, restorative dentistry, and implantology. This includes pertinent research as well as clinical methodology (their interdependence and relationship should be addressed where applicable); proceedings of relevant symposia or conferences; and quality review papers. Original manuscripts are considered for publication on the condition that they have not been published or submitted for publication elsewhere.
