Abstract

Purpose

The purpose of this study was to verify the effect of our previously proposed mesiodistal distance for multiple posterior implants on preserving peri-implant bone, and to provide a measurable criterion for predicting implant prognosis.

Methods

One hundred and two patients with dental implants placed in the posterior free-end edentulous arches were recruited in this cross-sectional study. Calibrated X-rays (peri-apical [PA] or bite-wing x-ray) were collected to measure the mesiodistal space as well as the corresponding bone resorption of implants after prosthesis placement. Implants were assigned to the test/control group according to whether their mesiodistal distance following our proposed algorithm. After adjusting covariates, logistic multivariate regression analyses were performed to examine the relationship between inter-implant distance and marginal bone loss (MBL) during each follow-up interval. The effect of smoking habits was also analyzed.

Results

Every observation period exhibited great significance between experimental and control group on peri-implant bone level (p = 0.006, 0.005, 0.001, 0.025, 0.001, correspondingly) and the difference had a tendency to grow as time went by except 4-year (MD = −0.19, −0.39, −0.43, −0.30, −1.26, correspondingly). While no significant difference was observed between smokers and nonsmokers in the same group (p > 0.05).

Conclusion

The mesiodistal algorithm of 4–4.6 mm (implant to adjacent canine tooth), 7–7.4 mm, 8–8.5 mm, and 9–9.5 mm was proved to be effective for maintaining peri-implant bone level. It was also observed in our study that the impact of inter-implant distance outweighed that of smoking. This study provided clinicians predictable prognostic outcomes for implants and reference for deciding treatment plans.

种植体近远端距离对种植体周围骨丢失的影响：横断面回顾性研究。

目的：本研究的目的是验证我们之前提出的多个后路种植体中远端距离对保留种植体周围骨的影响，并为预测种植体预后提供一个可测量的标准。方法：采用横断面研究方法，对102例在无牙后端游离弓种植牙的患者进行研究。收集校准过的x线（尖周x线或咬翼x线）测量假体放置后种植体的中远端间隙以及相应的骨吸收。根据种植体的中远端距离是否符合我们提出的算法，将种植体分配到试验组/对照组。在调整协变量后，进行logistic多变量回归分析，以检查每个随访期间种植体间距离与边缘骨质流失（MBL）的关系。对吸烟习惯的影响也进行了分析。结果：各观察期实验组与对照组种植体周围骨水平差异均有显著性意义（p = 0.006、0.005、0.001、0.025、0.001），且除4年差异有随时间增加的趋势（MD = -0.19、-0.39、-0.43、-0.30、-1.26）。而同一组吸烟者与非吸烟者之间无显著差异（p < 0.05）。结论：4-4.6 mm（种植体至邻近犬牙）、7-7.4 mm、8-8.5 mm、9-9.5 mm的中远端算法可有效维持种植体周围骨水平。在我们的研究中也观察到种植体间距离的影响大于吸烟的影响。本研究为临床医生预测种植体的预后和制定治疗方案提供参考。

期刊介绍： The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
