研究目的: |
本研究拟开展前瞻性随机对照临床试验,比较导板配准与牙面配准在机器人辅助种植手术中三维定位精度、术前准备效率和操作便捷性方面的表现,以验证牙面配准在适宜牙列条件下的临床可行性及应用价值,为机器人种植的标准化推广提供科学依据。 |

|
Objectives of Study: |
This study intends to conduct a prospective randomized controlled clinical trial to compare the performance of guide plate alignment and tooth surface alignment in terms of three-dimensional positioning accuracy, preoperative preparation efficiency, and operational convenience in robotic-assisted implant surgery. The aim is to verify the clinical feasibility and application value of tooth surface alignment under suitable dental arch conditions, and to provide a scientific basis for the standardized promotion of robotic implantation. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用分层区组随机化以保证组间可比性并控制关键预后因素。以“缺牙区域”(前牙/后牙区)为分层因素,因其可能影响手术精度。随机序列由独立统计人员通过计算机生成,每层内按区组长度4或6以1:1比例分配至导板配准组或牙面配准组。分配结果存入密封编号信封或中心随机系统,仅在患者入组并签署知情同意后由主刀医生开启,以实现分配隐藏。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This study used stratified block randomization to ensure comparability between groups and control key prognostic factors. “Tooth loss region” (anterior/posterior) was used as the stratification factor, as it may affect surgical precision. The randomization sequence was generated by an independent statistician using a computer, with blocks of 4 or 6 within each stratum and a 1:1 allocation to either the guide-registration group or the tooth-surface registration group. Allocation results were kept in sealed, numbered envelopes or a central randomization system and were only revealed to the surgeon after patient enrollment and informed consent, ensuring allocation concealment. |
