Abstract

Objectives

This study aimed to assess the effects of deproteinized bovine bone mineral with collagen (DBBMC) combined with deproteinized bovine bone mineral (DBBM) on facial alveolar bone augmentation in the anterior maxillary region.

Materials and Methods

Patients receiving dental implant placement with simultaneous lateral bone augmentation using DBBM (control group) or DBBMC combined with DBBM (test group) were included in the study. The radiographic assessment of facial alveolar bone, such as facial horizontal bone thickness (FHBT), facial vertical bone level (FVBL), and square of facial bone (SFB), was taken by cone beam computed tomography (CBCT). Generalized estimated equation (GEE) was performed to identify influencing factors associated with the contraction in square of facial bone (SFBC).

Results

A total of 164 implants from 164 patients were included in this study. After 6 months post-surgery, the SFBC and the alterations of FHBT and FVBL in the test group were significantly higher than those in the control group (p < 0.05). After 1–2 years after restorations, the SFBC and the alterations of FHBT and FVBL in the test group were significantly lower than those in the control group (p < 0.05). Spearman correlation analysis demonstrated a positive correlation between the alterations of FVBL and FHBT at the implant platform level in the test group (r_s = 0.322, p = 0.001; r_s = 0.349, p = 0.002). Implant timing of early loading (p = 0.014) and the implant site of the central incisor (p = 0.040) were significantly associated with the SFBC.

Conclusions

The applications of DBBMC combined with DBBM achieved better facial alveolar bone augmentation in the anterior maxillary region, especially in early implant placement.

脱蛋白牛骨矿物质与胶原蛋白用于上颌前嵴隆胸：一项回顾性队列研究。

目的：探讨胶原脱蛋白牛骨矿物质（DBBMC）联合脱蛋白牛骨矿物质（DBBM）对上颌前区面牙槽骨增强的影响。材料和方法：采用DBBM种植牙同时侧骨增强术的患者（对照组）或DBBMC联合DBBM（试验组）。采用锥形束计算机断层扫描（CBCT）对面牙槽骨进行面水平骨厚度（FHBT）、面垂直骨水平（FVBL）、面骨方尺（SFB）等影像学评价。应用广义估计方程（Generalized estimation equation， GEE）确定影响骨方收缩的相关因素。结果：本研究共纳入164例患者的164颗种植体。术后6个月，试验组SFBC及FHBT、FVBL变化显著高于对照组(p s = 0.322, p = 0.001；Rs = 0.349, p = 0.002)。种植时间的早期加载（p = 0.014）和种植位置的中切牙（p = 0.040）与SFBC显著相关。结论：DBBMC联合DBBM在上颌前区获得了较好的面牙槽骨增强效果，特别是在早期种植中。

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.
