Abstract

Objective

To compare collected bone weight and the frequency of autologous bone harvesting from the flutes of surgical drills used for implant bed preparation using two different drilling techniques. A comparative evaluation of radiographic bone density and bone quality was also made.

Materials and Methods

A randomized clinical trial was made of 66 dental implants in patients with a single posterior edentulous site. The compared drilling techniques were high-speed drilling with irrigation (control group) and low-speed drilling without irrigation (test group). The bone collected in both groups was dried and weighed with a precise electronic balance. The frequency of harvesting was calculated. The median radiographic bone density of each implant site was measured using cone-beam computed tomography (CBCT) pixel values. Patient sex, age, implant position and dimensions, as well as the last drill diameter were analyzed as independent variables. The level of significance was 5%.

Results

The harvesting of bone chips from drill flutes proved possible in 51.5% of the procedures in the control group and in 100% in the test group (p < 0.001). There were also statistically significant differences in bone weight between the control group (6.7 ± 10.6 mg) and the test group (41.9 ± 30.3 mg) (p < 0.001). The CBCT pixel values were directly correlated with the collected bone weight in both groups. The median radiographic bone density, arch and last drill diameter were significantly associated with harvesting bone frequency and collected bone weight (p < 0.05).

Conclusions

Our findings suggest that the frequency and weight of autologous bone harvested from drills are greater with low-speed drilling without irrigation than with high-speed drilling with irrigation. Radiographic bone density, arch and last drill diameter also significantly influenced the harvesting outcomes.

种植床准备过程中的自体骨采集：带灌洗的高速钻孔与不带灌洗的低速钻孔的随机临床试验比较。

目的比较使用两种不同钻孔技术制备种植床时，从手术钻头的凹槽中采集的骨重量和自体骨的采集频率。此外，还对放射骨密度和骨质量进行了比较评估：对单侧后部缺牙患者的 66 颗牙科种植体进行了随机临床试验。比较的钻孔技术是高速钻孔加灌洗（对照组）和低速钻孔不灌洗（试验组）。两组采集的骨质都经过干燥处理，并用精密的电子天平称重。计算采集频率。使用锥束计算机断层扫描（CBCT）像素值测量每个种植部位的放射骨密度中值。将患者性别、年龄、种植体位置和尺寸以及最后一次钻孔直径作为自变量进行分析。显著性水平为 5%：结果：对照组有 51.5%的手术可以从钻槽中获取骨屑，而试验组则为 100%（P）：我们的研究结果表明，不灌洗的低速钻孔与灌洗的高速钻孔相比，从钻孔中获取自体骨的频率和重量更大。放射学骨密度、牙弓和最后钻孔直径也对取骨结果有显著影响。

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.
