Abstract

Introduction

There is evidence that the apico-coronal implant position and the mucosal phenotype can affect the extent of peri-implant bone loss. This clinical trial analyzes the bone remodeling and marginal bone loss that occur around conical-connection implants placed equicrestally and subcrestally, assessing the effect of the peri-implant soft-tissue phenotype.

Methods

Fifty-one patients received 56 implants of distinct diameters (3.5 mm Ø n = 6; 4.3 mm Ø n = 41; 5 mm Ø n = 9) in the posterior part of the maxilla or mandible. The implants were placed equicrestally, 1 mm subcrestally and >1 mm subcrestally, depending on the initial supracrestal tissue height (STH). After 3 months of non-submerged healing, single metal-ceramic screw-retained implant-supported crowns were placed. Longitudinal measurements of STH, mucosal thickness and keratinized mucosa width (KMW) were made at the time of implant placement (T0), crown placement (T1), and after 3 (T2) and 6 months (T3) of prosthetic loading. At each of these points, a radiographic evaluation of bone remodeling and marginal bone loss was also performed.

Results

STH was significantly greater for implants placed >1 mm subcrestally than for those placed 1 mm subcrestally. After 12 months of follow-up, a very significant (p < 0.001) loss of KMW was observed, in addition to a marginal bone loss of 0.08 ± 0.1, 0.15 ± 0.2, and 0.14 ± 0.2 mm in the groups placed equicrestally, 1 mm subcrestally and >1 mm subcrestally, respectively. After the multiple linear regression, marginal bone loss was found to depend primarily on KMW (β = −0.43), while also being affected by STH (β = 0.32) and implant diameter (β = −0.28).

Conclusions

Marginal bone loss may be influenced by the position with respect to the bone crest, as well as the KMW, STH, and implant diameter. However, more well-controlled studies are needed to verify these above-mentioned findings with different implant designs and connections.

种植体周围粘膜的尺寸如何影响种植体等高和等低位置的边缘骨质流失？为期一年的临床试验。

引言：有证据表明，尖冠种植体的位置和粘膜表型会影响种植体周围骨质流失的程度。这项临床试验分析了等间隙和下间隙锥形连接种植体周围的骨重塑和边缘骨缺失情况，评估了种植体周围软组织表型的影响：51名患者在上颌或下颌后部接受了56颗直径不同的种植体（3.5 mm Ø n = 6；4.3 mm Ø n = 41；5 mm Ø n = 9）。根据最初的上嵴组织高度（STH），种植体分别植入等高、上嵴下1毫米和上嵴下>1毫米处。经过 3 个月的非浸水愈合后，植入单个金属陶瓷螺丝固位的种植体支撑冠。在种植体植入（T0）、牙冠植入（T1）、修复体加载 3 个月（T2）和 6 个月（T3）后，对 STH、粘膜厚度和角化粘膜宽度（KMW）进行纵向测量。在上述每个时间点，还对骨质重塑和边缘骨质流失进行了放射学评估：结果：种植体植入嵴下大于 1 mm 时，STH 明显大于植入嵴下 1 mm 时。经过 12 个月的随访，结果显示，种植体在胸骨下 1 毫米处的 STH 明显高于种植体在胸骨下 1 毫米处的 STH。多元线性回归后发现，边缘骨质流失主要取决于 KMW（β = -0.43），同时也受到 STH（β = 0.32）和种植体直径（β = -0.28）的影响：边缘骨质流失可能会受到相对于骨嵴的位置以及 KMW、STH 和种植体直径的影响。然而，还需要进行更多有良好对照的研究，通过不同的种植体设计和连接方式来验证上述结论。

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.
