Abstract

Background

In recent years, platform switching implant treatment has been increasing, which is believed to minimize bone loss around the implant after placement. However, there have been no reports on the relationship between keratinized mucosa width (KMW) and bone loss and soft tissue recession in platform switching implants.

Objective

We evaluated the effect of the KMW on the amount of bone loss and soft tissue recession around a platform switching implant retrospectively using multivariate analysis.

Materials and Methods

This one-year retrospective study included 91 implants in 48 patients. Age, sex, a history of periodontitis, implant location, oral hygiene status, and the KMW were included as explanatory variables to evaluate bone loss (BL) and buccal gingival height (GH). Generalized estimating equations (GEEs) were used to evaluate the effect of the KMW on platform switching peri-implant tissues.

Results

The mean bone loss on the mesial (ΔBLm), distal (ΔBLd), and buccal (ΔBLb) sides of the implant were 0.16 ± 0.27 mm, 0.19 ± 0.34 mm, and 0.24 ± 0.50 mm, respectively, at 1 year after superstructure placement. The mean amount of change of GH (ΔGH) on the buccal side was 0.30 ± 0.47 mm. After correcting for confounders using GEEs, the results suggested that KMW <1.5 mm was a significant factor (P < 0.001) for bone loss over time in ΔBLm, ΔBLd, and ΔBLb. In addition, for soft tissues on the buccal side, KMW <1.5 mm was a significant factor for ΔGH reduction over time (P < 0.001).

Conclusions

Keratinized mucosa width ≥1.5 mm was associated with a higher probability less hard and soft tissue recession around the platform switching implant after 1 year from superstructure placement.

角化粘膜对种植体周围组织影响的多变量分析：一项回顾性研究。

背景：近年来，平台转换种植治疗越来越多，这种治疗方法被认为可以最大限度地减少种植体植入后周围的骨质流失。然而，目前还没有关于平台切换种植体的角化粘膜宽度（KMW）与骨质流失和软组织退缩之间关系的报道：我们使用多变量分析法回顾性地评估了角化粘膜宽度对平台转换种植体周围骨量损失和软组织退缩的影响：这项为期一年的回顾性研究包括 48 名患者的 91 个种植体。将年龄、性别、牙周炎病史、种植体位置、口腔卫生状况和 KMW 作为解释变量，以评估骨量（BL）和颊龈高度（GH）。使用广义估计方程（GEEs）评估 KMW 对平台切换种植体周围组织的影响：结果：上部结构植入 1 年后，种植体中侧（ΔBLm）、远侧（ΔBLd）和颊侧（ΔBLb）的平均骨量损失分别为 0.16 ± 0.27 mm、0.19 ± 0.34 mm 和 0.24 ± 0.50 mm。颊侧 GH 的平均变化量（ΔGH）为 0.30 ± 0.47 毫米。在使用 GEE 对混杂因素进行校正后，结果表明 KMW角化粘膜宽度≥1.5 毫米与上部结构植入 1 年后平台切换种植体周围软硬组织衰退的可能性较低有关。

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.
