Primary stability is an important factor for dental implant success. In the past years, a new method for bone site preparation was introduced, named osseodensification (OD). OD produces a condensation of the trabecular portion of the bone, increasing bone-to-implant contact and primary stability. This study aims to compare the effect of OD in cylindrical and conical implants to conventional instrumentation. A total of forty implants, divided into four groups, were placed in porcine tibia: cylindrical conventional (1a), cylindrical OD (1b), conical conventional (2a) and conical OD (2b). Each implant was measured for implant stability quotient (ISQ), insertion torque (IT) and removal torque (RT). Group 2b showed the higher values for each of the evaluated parameters; groups 1b and 2b showed better results than 1a and 2a, respectively. Regarding the IT and RT, group 1b achieved higher values than group 2a, but not for ISQ. The inter-group comparison showed significant difference between groups 1a vs 2a, 1a vs 2b and 1b vs 2b for ISQ and 1a vs 1b and 1a vs 2b for RT analysis. OD resulted in improved ISQ, IT and RT of both cylindrical and conical implants.
初期稳定性是牙种植成功的一个重要因素。在过去几年中，引入了一种新的骨位点制备方法，称为骨致密化（OD）。OD可使骨小梁部分致密化，增加骨与种植体的接触以及初期稳定性。本研究旨在比较OD应用于圆柱形和锥形种植体时与传统器械操作的效果。总共40枚种植体被分为四组，植入猪胫骨中：圆柱形传统组（1a）、圆柱形OD组（1b）、锥形传统组（2a）和锥形OD组（2b）。对每枚种植体测量种植体稳定性商数（ISQ）、植入扭矩（IT）和取出扭矩（RT）。2b组在每个评估参数上均显示出较高的值；1b组和2b组分别比1a组和2a组显示出更好的结果。关于IT和RT，1b组的值高于2a组，但ISQ并非如此。组间比较显示，在ISQ方面，1a组与2a组、1a组与2b组以及1b组与2b组之间存在显著差异；在RT分析方面，1a组与1b组以及1a组与2b组之间存在显著差异。OD可提高圆柱形和锥形种植体的ISQ、IT和RT。
