Abstract

Purpose

This prospective case series aimed to investigate the effect of vertical alveoloplasty on the changes in keratinized mucosa width (KMW) following full-arch immediate implant placement and rehabilitation.

Materials and Methods

A total of 17 potential edentulous patients were enrolled and received implant placement and full-arch implant-supported immediate rehabilitations. The main outcome was to analyze the effect of vertical alveoloplasty on the changes in KMW. The amount of vertical alveoloplasty during implant surgery as well as the changes in KMW at buccal aspects from the day of surgery to 6 months post-surgery were recorded on the implant-level using a periodontal probe. The secondary outcome was to analyze the other possible factors that affected the changes in KMW. The included factors were the initial KMW, the distribution of implants in the maxilla and mandible, the distribution of implants in the anterior and posterior regions, the distribution of implants in extraction sockets and healed ridges, and gender. Mann-Whitney non-parametric tests and multiple linear regression adjusted by generalized estimating equations (GEE) were used to statistically analyze the data.

Results

A total of 121 implant positions were analyzed. The KMW was 4.1± 2.0 mm on the day of the surgery and 4.1± 1.7 mm 6 months post-surgery. The mean changes in KMW following 6 months were −0.1± 1.6 mm (p = 0.824). From the results of GEE, the vertical amount of alveoloplasty had no significant effect on changes in KMW. Both initial KMW and the distribution of implants in the anterior and posterior regions had significant impacts on the changes in KMW (p < 0.0001).

Conclusion

The amount of vertical alveoloplasty during implant surgery has no significant impact on the KMW. The KMW remained stable from baseline to 6 months after alveoloplasty, implant placement, and immediate rehabilitations in potential edentulous arches. The initial KMW and the distribution of implants in the anterior and posterior regions were the possible factors affecting changes in KMW.

垂直肺泡成形术对全牙弓即刻种植体植入和修复后角化粘膜宽度变化的影响：前瞻性病例系列。

目的：本前瞻性病例系列旨在研究垂直肺泡成形术对全牙弓即刻种植体植入和修复后角化粘膜宽度（KMW）变化的影响：共纳入 17 名潜在无牙颌患者，他们接受了种植体植入和全牙弓种植体支持即刻修复。主要结果是分析垂直肺泡成形术对 KMW 变化的影响。使用牙周探针记录种植手术过程中垂直牙槽成形术的量以及从手术当天到术后 6 个月期间颊侧 KMW 的变化。次要结果是分析影响 KMW 变化的其他可能因素。这些因素包括初始 KMW、种植体在上颌骨和下颌骨的分布、种植体在前部和后部的分布、种植体在拔牙窝和愈合脊的分布以及性别。采用曼-惠特尼非参数检验和经广义估计方程（GEE）调整的多元线性回归对数据进行统计分析：共分析了 121 个种植体位置。手术当天的 KMW 为 4.1±2.0 mm，术后 6 个月的 KMW 为 4.1±1.7 mm。6 个月后 KMW 的平均变化为 -0.1± 1.6 mm (p = 0.824)。从 GEE 的结果来看，肺泡成形术的垂直量对 KMW 的变化没有显著影响。初始 KMW 和种植体在前后区域的分布对 KMW 的变化均有显著影响（p 结论：种植体在前后区域的分布对 KMW 的变化无显著影响：种植手术中垂直肺泡成形术的数量对 KMW 没有明显影响。在潜在缺牙弓进行牙槽成形术、种植体植入和即刻修复后，KMW 从基线到 6 个月保持稳定。初始 KMW 以及种植体在前后区域的分布是影响 KMW 变化的可能因素。

期刊介绍： The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. The journal publishes evidence-based original scientific articles presenting information that is relevant and useful to prosthodontists. Additionally, it publishes reports of innovative techniques, new instructional methodologies, and instructive clinical reports with an interdisciplinary flair. The journal is particularly focused on promoting the study and use of cutting-edge technology and positioning prosthodontists as the early-adopters of new technology in the dental community.
