Abstract

Objectives: To analyze the effects of three osteotomy drill designs (conventional [CON], reverse helix [REX], and densification [DEN]) and running directions on heat generation, primary implant stability (PS), block-to-implant contact (BIC)%, peri-implant block volume (BV), and resistance to unscrewing forces in a low-density alveolar bone model.

Method and materials: Eighty-eight dental implants were inserted into artificial bone blocks using manual and computer-controlled osteotomies. Temperature changes (Δ°C), insertion torque value (ITV), resonance frequency analyses (ISQ), BIC%, and BV were measured. Statistical analyses used ANOVA and Kruskal-Wallis tests (p<0.05).

Results: DEN drilling produced the lowest Δ°C (17.52±2.57°C and 28.06±4.35°C for 2nd and 3rd drills), while CON had the highest (27.53±5.17°C and 38.03±8.08°C). Counter-clockwise (CCW) CON drilling significantly reduced Δ°C compared to clockwise (CW). DEN achieved highest PS (38.01±1.87 N/cm, 65±4.69 ISQ) and removal torque (25.4±5.08 N/cm), while CON CW had lowest (33.23±2.91 N/cm, 61.83±4.28 ISQ). DEN showed the highest BV (87.71±4.23 mm³) but the lowest BIC (49.12%±2.93%). CCW CON drilling improved ITV over CW (36.21±3.63 vs 33.23±2.91 N/cm).

Conclusion: DEN drilling demonstrated superior performance in heat reduction, PS, and BV, but had lower BIC%. CCW running of CON drills showed improvements over CW in several parameters. While DEN excelled in most aspects, its lower BIC% and the positive outcomes of CCW CON drilling warrant further investigation.

植体植入截骨钻设计的热、力学和密度分析：对代表IV型骨的泡沫块的分析。

目的：分析常规[CON]、反螺旋[REX]和致密化[DEN]三种截骨钻头设计及运行方向对低密度牙槽骨模型产热、初级种植体稳定性（PS）、块体与种植体接触（BIC）%、种植体周围块体体积（BV）和抗旋脱力的影响。方法与材料：采用人工截骨术和电脑截骨术将88颗种植体植入人工骨块中。测量温度变化（Δ°C）、插入扭矩值（ITV）、共振频率分析（ISQ）、BIC%和BV。统计分析采用方差分析和Kruskal-Wallis检验(结果：DEN钻孔产生的最低Δ°C（第2次和第3次钻孔分别为17.52±2.57°C和28.06±4.35°C）， CON最高（27.53±5.17°C和38.03±8.08°C）。与顺时针钻井（CW）相比，逆时针钻井（CCW）可显著降低Δ°C。DEN的最大扭矩（38.01±1.87 N/cm, 65±4.69 ISQ）和最大扭矩（25.4±5.08 N/cm）， CON CW的最小扭矩（33.23±2.91 N/cm, 61.83±4.28 ISQ）。DEN的BV最高（87.71±4.23 mm³），BIC最低（49.12%±2.93%）。与CW相比，CCW CON钻井提高了ITV（36.21±3.63 N/cm vs 33.23±2.91 N/cm）。结论：DEN钻孔在热还原、PS和BV方面具有较好的性能，但BIC%较低。CON钻头的CCW下入在几个参数上都优于CW。虽然DEN在大多数方面都表现出色，但其较低的BIC%和CCW CON钻井的积极成果值得进一步研究。
