摘　　要：目的探讨高精度3D整合数字化种植导板对错颌畸形牙列缺损患者口腔种植修复效果、咬合关系及咀嚼功能的影响。方法选取2021年1月至2023年12月郑州大学第一附属医院收治的107例错颌畸形牙列缺损患者纳入研究,按照随机数表法分为观察组54例和对照组53例。观察组患者给予高精度3D整合数字化种植导板行口腔种植修复,对照组患者给予常规口腔种植修复。比较两组患者种植体偏差情况、修复后6个月修复效果、修复前及修复后6个月的咬合关系[咬合力值(TOF)、力中心点位置(COF)、力不对称指数(AOF)、力中心点最大位移(MMCOF)]、咀嚼功能、牙周指标[探诊深度(PD)、龈沟出血指数(SBI)、菌斑指数(PLI)],同时比较两组患者修复后6个月内的并发症发生率和满意度。结果观察组患者的种植体顶部、根部、角度、深度偏差值分别为(0.48±0.13)mm、(0.50±0.15)mm、(0.14±0.04)°、(0.41±0.10)mm,明显小于对照组的(0.61±0.17)mm、(0.64±0.18)mm、(0.20±0.06)°、(0.57±0.12)mm,差异均有统计学意义(P<0.05);修复后6个月,观察组患者的修复优良率为98.11%,明显高于对照组的82.35%,差异有统计学意义(P<0.05);修复后6个月,观察组患者的TOF、咀嚼效率分别为(13.62±2.36)×10^(3)、(84.62±5.01)%,明显高于对照组的(11.09±1.78)×10^(3)、(77.08±5.84)%,COF、AOF、MMCOF分别为(-4.52±0.63)mm、(11.35±1.26)%、(6.93±1.06)mm,明显低于对照组的(-3.71±0.45)mm、(13.87±1.71)%、(8.22±1.34)mm,差异均有统计学意义(P<0.05);修复后6个月,观察组患者的PD、SBI、PLI分别为(3.13±0.34)mm、(1.36±0.30)分、(1.05±0.17)分,明显低于对照组的(4.38±0.49)mm、(2.07±0.42)分、(1.48±0.23)分,差异均有统计学意义(P<0.05);修复后6个月内观察组患者的并发症发生率为5.66%,明显低于对照组的21.57%,差异有统计学意义(P<0.05);观察组患者的满意度为96.23%,明显高于对照组的80.39%,差异有统计学意�Objective To investigate the impact of high-precision 3D integrated digital implant guides on oral implant restoration,occlusal relationship,and masticatory function in patients with malocclusion and dentition defects.Methods A total of 107 patients with malocclusion and dentition defects admitted to the First Affiliated Hospital of Zhengzhou University from January 2021 to December 2023 were enrolled in the study.They were randomly divided into an observation group(54 cases)and a control group(53 cases)using a random number table.Patients in the observation group received oral implant restoration using high-precision 3D integrated digital implant guides,while those in the control group received conventional oral implant restoration.Implant deviation,restoration outcomes at 6 months post-restoration,occlusal relationship(occlusal force[TOF],center of force position[COF],asymmetry index of force[AOF],maximum displacement of the center of force[MMCOF]),masticatory function,periodontal indicators(probing depth[PD],sulcus bleeding index[SBI],plaque index[PLI]),complication rates within 6 months post-restoration,and patients’satisfaction were compared between the two groups.Results The deviations at the implant apex,root,angle,and depth in the observation group were(0.48±0.13)mm,(0.50±0.15)mm,(0.14±0.04)°,and(0.41±0.10)mm,respectively,significantly smaller than(0.61±0.17)mm,(0.64±0.18)mm,(0.20±0.06)°,and(0.57±0.12)mm in the control group(P<0.05).At 6 months post-restoration,the excellent and good rate of restoration in the observation group was 98.11%,significantly higher than 82.35%in the control group(P<0.05).The TOF and masticatory efficiency in the observation group were(13.62±2.36)×10^(3) and(84.62±5.01)%,respectively,significantly higher than(11.09±1.78)×10^(3) and(77.08±5.84)%in the control group,while COF,AOF,and MMCOF were(-4.52±0.63)mm,(11.35±1.26)%,and(6.93±1.06)mm,respectively,significantly lower than(-3.71±0.45)mm,(13.87±1.71)%,and(8.22±1.34)mm in the control group(P<0.05).The PD,S
