摘要

目的 牙科界广泛接受种植牙。尽管多项研究报告显示种植牙的存活率很高,但并发症仍有可能发生。种植失败与不同的风险因素有关,包括种植体的长度和直径。然而,目前尚未达成明确的共识。本研究旨在评估与种植失败相关的不同风险因素的影响。纳入标准为 2005 年 1 月 1 日至 2022 年 12 月 31 日期间植入的牙科植入物。我们收集了患者和种植体相关变量的数据。我们使用边际 Cox 比例危险模型来研究潜在因素与种植失败之间的关系。147 位患者中有 11 位种植失败,而 479 个种植体中有 17 个失败。种植体在最后时间点的累积存活率为 95.3%。多变量边际 Cox 分析显示,有提示性证据表明,与种植体长度(≥10 毫米)相比,种植体长度(<10 毫米)大大增加了种植失败的风险(参考值:<10 毫米,危险比,0.07;95% 置信区间,0.01-0.34;p = 0.001)。虽然种植失败是由多种因素造成的,而种植体长度只是导致种植体缺失的众多因素之一,但临床医生必须意识到种植体长度的潜在影响,并做出治疗决定。

Influence of implant length and diameter on implant failure: A retrospective study

Objective

Dental implants are widely accepted in the dental community. Although several studies have reported high dental implant survival rates, complications can still occur. Implant failure is associated with different risk factors, including implant length and diameter. However, no clear consensus has yet been reached. This study aimed to evaluate the influence of different risk factors associated with implant failure.

Methods

This study included patients who received dental implants at Kyoto University Hospital. The inclusion criteria were dental implants placed between January 1, 2005 and December 31, 2022. Data on patient- and implant-related variables were collected. We used a marginal Cox proportional hazards models to investigate the association between the potential factors and implant failure.

Results

This study included 147 patients who received 479 dental implants. Eleven of the 147 patients experienced implant failure, whereas 17 of the 479 implants failed. The cumulative survival rate of dental implants at the final time point was 95.3%. Multivariable marginal Cox analysis showed suggestive evidence that implant length (<10 mm) greatly increased the risk of implant failure compared with implant length (≥10 mm) (reference: <10 mm, hazard ratio, 0.07; 95% confidence interval, 0.01–0.34; p = 0.001).

Conclusions

A cumulative survival rate comparable to that reported in other studies was achieved over prolonged periods of time. Although implant failure is multifactorial and implant length is only one of many factors contributing to implant loss, clinicians must be aware of the potential influence of implant length and make treatment decisions.
