Dental or skeletal anchoring plays a significant role in the orthodontic treatment of various malocclusions. Miniscrews are now regarded as stable skeletal anchoring. Despite their popularity, miniscrew success rates in studies range from 83.9 to 93.3%. Surface treatment is one of its properties that is now being extensively researched and enhanced. Consequently, the purpose of this systematic review is to ascertain how miniscrew surface treatment affects insertion torque, success rate, and removal torque.
The protocol for conducting a systematic literature review followed the PRISMA criteria. The keywords "mini-implant", "mini-screw", "orthodontic mini screws", "survival rate", and "surface treatment" were used to search electronic databases. This systematic review included human studies published in English within the previous five years that compared the success rates of miniscrews with and without changed surfaces.
Four included studies assessed the effect of surface modification on the success rate; two of them examined the impact on insertion torque, one the removal torque, and one assesed the periotest value. The rough surface group achieved a higher success rate than the non-modified group, although the difference was not statistically significant. The treated surface group had higher removal torque than the non-treated group, but the difference was not statistically significant.
Quantitative and qualitative analysis revealed that surface-treated miniscrews had a greater success rate and insertion torque than non-treated ones, although the difference was not statistically significant.
牙支抗或骨支抗在各类错牙合畸形的正畸治疗中发挥着重要作用。微型螺钉现被视为稳定的骨支抗。尽管其广受欢迎，但在各项研究中微型螺钉的成功率在83.9%至93.3%之间。表面处理是目前正在广泛研究和改进的特性之一。因此，本系统评价的目的是确定微型螺钉表面处理如何影响植入扭矩、成功率和拆除扭矩。
进行系统文献综述的方案遵循PRISMA标准。使用关键词“微型种植体”“微型螺钉”“正畸微型螺钉”“存活率”和“表面处理”检索电子数据库。本系统评价纳入了过去五年内发表的英文人体研究，这些研究比较了表面改变与未改变的微型螺钉的成功率。
四项纳入研究评估了表面改性对成功率的影响；其中两项研究考察了对植入扭矩的影响，一项研究考察了对拆除扭矩的影响，一项研究评估了牙周探测值。粗糙表面组的成功率高于未改性组，尽管差异无统计学意义。处理表面组的拆除扭矩高于未处理组，但差异无统计学意义。
定量和定性分析表明，表面处理的微型螺钉比未处理的微型螺钉具有更高的成功率和植入扭矩，尽管差异无统计学意义。
