Abstract

Objective

To analyse marginal bone level changes at implants placed using high-speed drilling (800 rpm) with irrigation versus low-speed drilling (150 rpm) without irrigation. Peri-implant soft-tissue parameters were assessed and the influence of bone density and vertical dimensions of supracrestal soft tissue on marginal bone level changes was evaluated.

Material and Methods

Patients with a single posterior edentulous area were included in a randomized parallel single-blinded clinical trial. The study groups were: high-speed drilling with irrigation (CG:control group) and low-speed drilling without irrigation (TG:test group). Marginal bone level changes were measured using parallelized periapical radiographs during 12-months. Probing depth, bleeding on probing, plaque index, buccal keratinized mucosa, suppuration and recession were measured. The mean total bone density was evaluated in Hounsfield Units. Mann–Whitney U-test for non-parametric variables and t-test for parametric variables were employed.

Results

A total of 66 patients were included (33 per group). The implant success rate was 100% for both groups according to Misch classification. No statistically significant differences were found regarding marginal bone loss (CG: −0.03 (0.17); TG: −0.01 (0.05)), bone remodeling (CG: 0.81 (0.64); TG: 0.86 (0.54)), or peri-implant soft tissue parameters (p > 0.05). Bone density showed no significant correlation with the peri-implant bone and soft-tissue changes. The vertical supracrestal soft tissue was inversely correlated to peri-implant bone remodeling.

Conclusions

Within the limits, high-speed drilling with irrigation and low-speed drilling without irrigation had no statistically significant influence on the peri-implant marginal bone and soft tissue changes during 12 months of follow-up. These variables were not significantly influenced by bone density.

高速钻孔加冲洗与低速钻孔不加冲洗对种植体周围边缘骨改变的影响：一项随访12个月的随机临床试验。

目的：分析高速钻孔（800转/分）和低速钻孔（150转/分）不冲洗种植体的边缘骨水平变化。评估种植体周围软组织参数，评估骨密度和截骨上软组织垂直尺寸对边缘骨水平变化的影响。材料和方法：将单侧无牙区患者纳入随机平行单盲临床试验。研究组分为高速钻孔灌洗组（CG：对照组）和低速钻孔不灌洗组（TG：试验组）。在12个月内使用平行根尖周围x线片测量边缘骨水平变化。观察探诊深度、探诊出血、菌斑指数、口腔角化黏膜、化脓及萎缩情况。以Hounsfield单位评估平均总骨密度。非参数变量采用Mann-Whitney u检验，参数变量采用t检验。结果：共纳入66例患者，每组33例。根据Misch分类，两组种植成功率均为100%。两组在边缘骨质流失方面差异无统计学意义(CG: -0.03 (0.17)；TG: -0.01(0.05))，骨重塑(CG: 0.81 (0.64)；TG: 0.86(0.54))或种植体周围软组织参数（p < 0.05）。骨密度与种植体周围骨及软组织变化无显著相关性。垂直的耻骨上软组织与种植体周围骨重塑呈负相关。结论：在限定范围内，高速钻孔灌洗与低速钻孔不灌洗对种植体周围边缘骨及软组织变化的影响无统计学意义。这些变量不受骨密度的显著影响。试验注册：唯一识别号：NCT05286866。
