The implant primary stability is a fundamental condition for avoiding implant micro-motions that might result in fibrous encapsulation; its achievement is facilitated by macro- and micro-geometry of the implant, and by the bone density and architecture at the intended implant site. The aim was to evaluate an osteocondensing drilling protocol for dental implant positioning compared to standard protocol on polyurethane block. A total of 40 implants, 20 for each osteocondensing group (Test) and 20 for standard drilling group (Control), were positioned. Insertion torque (IT), removal torque (RT), and Periotest were measured. A IT, RT, and Periotest significant difference was present in favor of the implant osteocondensing protocol. The results suggested that osteocondensing protocol represents a useful technique for implant placement in poor density bone.

在不同密度的聚氨酯块中使用骨浓缩钻孔方案进行植入物初步稳定性

种植体的初级稳定性是避免可能导致纤维包封的种植体微动的基本条件；它的实现得益于植入物的宏观和微观几何形状，以及预期植入部位的骨密度和结构。目的是评估用于牙种植体定位的骨浓缩钻孔方案与聚氨酯块的标准方案相比。总共放置了 40 个种植体，每个骨浓缩组（测试）20 个，标准钻孔组（对照组）20 个。测量了插入扭矩 (IT)、移除扭矩 (RT) 和 Periotest。IT、RT 和 Periotest 存在显着差异，有利于植入骨浓缩方案。
