Conventional alveoloplasty procedure using manual instruments results in higher resorption of the residual alveolar ridge, which is unsuitable for denture construction. The purpose of this study was to evaluate the effect of piezosurgery-assisted alveoloplasty using minimally invasive technique compared to that of the conventional technique.
This was a comparative study. The study sample consisted of 35 edentulous patients with bilateral bony spicules requiring alveoloplasty. The primary outcome variables assessed were time required for alveoloplasty, postoperative pain using visual analogue scale (VAS), and postoperative healing using Landry, Turnbull, and Howley healing index. The differences between the outcome variables were statistically analyzed using paired -test.
The participants consisted of 35 patients (25 men and 10 women; age range: 38-83 years) diagnosed with bilateral bony spicules on the edentulous alveolar ridge. There was a statistically highly significant difference between both groups with respect to the outcome variables such as time required, VAS at 2 day, and healing index at 7 day with higher mean of time required (in sec), higher mean of VAS, and lower healing index for conventional group as compared to piezo group ( < 0.05).
Alveoloplasty done using piezosurgery not only reduces patient's postoperative discomfort but also maintains the alveolar bone integrity by not disturbing the soft-tissue and hard-tissue architecture, allowing faster healing of tissues, which makes the future prosthesis replacement easier.
使用手动器械进行的传统牙槽骨修整术会导致剩余牙槽嵴更高程度的吸收，这不适用于义齿修复。本研究的目的是评估与传统技术相比，采用微创技术的压电手术辅助牙槽骨修整术的效果。
这是一项对比研究。研究样本包括35例双侧存在骨尖且需要进行牙槽骨修整术的无牙患者。评估的主要结果变量包括牙槽骨修整术所需时间、使用视觉模拟量表（VAS）评估的术后疼痛以及使用兰德里、特恩布尔和豪利愈合指数评估的术后愈合情况。使用配对t检验对结果变量之间的差异进行统计学分析。
参与者包括35例患者（25名男性和10名女性；年龄范围：38 - 83岁），诊断为无牙牙槽嵴双侧存在骨尖。两组在诸如所需时间、第2天的VAS以及第7天的愈合指数等结果变量方面存在统计学上的高度显著差异，传统组的所需时间平均值（以秒为单位）更高、VAS平均值更高且愈合指数更低，与压电组相比（P < 0.05）。
使用压电手术进行牙槽骨修整术不仅能减轻患者术后不适，还能通过不干扰软组织和硬组织结构来维持牙槽骨完整性，使组织愈合更快，这使得未来的义齿修复更容易。
