The aim of this study was to evaluate the use of a flexible synthetic polymer bone graft to provide implant stability during implant placement in a dense cortical bone model. In the control group (Group 1), sockets were prepared on polyurethane blocks according to the standard implant socket drilling protocol; both oversizing and deepening were applied in Group 2; and only oversizing was applied in Group 3. In Groups 2 and 3, flexible synthetic polymer bone grafts were placed in the sockets prior to implant placement. The implants were placed at the bone level in all groups. The highest torque value obtained was recorded as the insertion torque. In this study, 75 implant sites were included across three groups. The torque values of the implants in the control group were significantly higher than those of the implants with the oversized and deepened sockets and the oversized-only sockets ( < 0.05; < 0.01). The torque values of the implants with the oversized and deepened sockets were significantly higher than those of the implants with the oversized-only sockets ( < 0.01). In this study, a flexible synthetic polymer bone graft was shown to be effective in achieving implant stability in the management of implants where there has been a loss of primary stability.
本研究的目的是评估在致密皮质骨模型中植入种植体时,使用柔性合成聚合物骨移植材料来提供种植体稳定性的效果。在对照组(第1组)中,按照标准种植体窝洞钻孔方案在聚氨酯块上制备窝洞;第2组同时采用了扩大孔径和加深窝洞的操作;第3组仅采用了扩大孔径的操作。在第2组和第3组中,在植入种植体之前将柔性合成聚合物骨移植材料放入窝洞中。所有组的种植体均放置在骨水平位置。获得的最高扭矩值记录为植入扭矩。本研究共纳入了三组的75个种植位点。对照组种植体的扭矩值显著高于扩大孔径并加深窝洞组和仅扩大孔径组的种植体(<0.05;<0.01)。扩大孔径并加深窝洞组种植体的扭矩值显著高于仅扩大孔径组的种植体(<0.01)。在本研究中,柔性合成聚合物骨移植材料被证明在处理失去初始稳定性的种植体时,对于实现种植体稳定性是有效的。
