Abstract

Introduction: This study evaluated whether drill shape and bone preparation influences the primary stability of the implant using resonance frequency analysis and insertion torque values.

Materials and methodology: In this study, four most common, commercially available drill systems were used in this study. Bovine bone was chosen for the study. All the implants were chosen of the same dimension (3.5 mm ȕ 13 mm) to avoid bias and error. For convenience the study was divided into two parts. Part I of the study included performing osteotomy per manufacturer's instructions with a variability in the speed of the drilling at 300 rpm and 800 rpm, respectively. All the implants were placed at bone level, which was checked by taking radiographs. The primary stability of the implants of all the four different companies were measured using an ISQ machine (Penguin, Sweden). Part II of the study involved single drilling kit for the study. Sequential drilling protocol is selected for the second part of the study. All the four-implant system are placed using the same set of drill system. The implants are placed at 300 rpm. ISQ values are recorded using RFA machine (Penguin, Sweden) for each implant. IOPA was also recorded for the study.

Results: The results were subjected to analysis.

Conclusion: The results of this study suggest that implant drill shape did not have any significant effect on the overall primary stability of the implant. However, in certain implants, due to their unique design, custom drilling kits might be more feasible to use.

确定钻头形状对种植体初级稳定性的影响:一项体外试验研究。
本研究通过共振频率分析和插入扭矩值来评估钻头形状和骨准备是否影响种植体的初级稳定性。材料和方法:在本研究中,使用了四种最常见的商用钻头系统。研究中选择了牛骨。所有种植体均选择相同尺寸(3.5 mm ~ 13 mm),以避免偏差和误差。为方便起见,研究分为两部分。研究的第一部分包括根据制造商的说明进行截骨术,钻孔速度分别为300转/分和800转/分。所有的植入物都放置在骨水平,通过x线片检查。使用ISQ机器(Penguin, Sweden)测量所有四家不同公司种植体的初级稳定性。研究的第二部分涉及单个钻井工具的研究。研究的第二部分选择了顺序钻井方案。所有四种植体系统使用同一套钻系统放置。植入物以每分钟300转的速度放置。使用RFA机器(Penguin, Sweden)记录每个植入物的ISQ值。该研究还记录了IOPA。结果:对结果进行了分析。结论:本研究结果提示种植体钻孔形状对种植体整体初级稳定性无显著影响。然而,在某些植入物中,由于其独特的设计,定制的钻孔套件可能更可行。

期刊介绍: MEDICAL IMPLANTS are being used in every organ of the human body. Ideally, medical implants must have biomechanical properties comparable to those of autogenous tissues without any adverse effects. In each anatomic site, studies of the long-term effects of medical implants must be undertaken to determine accurately the safety and performance of the implants. Today, implant surgery has become an interdisciplinary undertaking involving a number of skilled and gifted specialists. For example, successful cochlear implants will involve audiologists, audiological physicians, speech and language therapists, otolaryngologists, nurses, neuro-otologists, teachers of the deaf, hearing therapists, cochlear implant manufacturers, and others involved with hearing-impaired and deaf individuals.
