Abstract

Objectives

Autogenous bone ring technique (BRT) is a one-stage vertical augmentation approach with simultaneous implant placement. The aim of this study was to compare the accuracy and efficacy of autogenous BRT assisted by dynamic navigation (DN) with freehand approach (FA) for vertical ridge augmentation.

Materials and Methods

Twenty-four patients eligible for autogenous BRT were randomly assigned to DN or FA groups. Digital preoperative design was conducted for both groups. BRT surgeries were executed with or without the aid of DN in the two groups. Accuracy outcomes evaluated angular and linear deviations at the bone ring in the donor site (BR-D), recipient site (BR-R), and implant entry/apex between planned and actual positions revealed by cone-beam computed tomography. Vertical augmentation-related outcomes, surgical complications, and patient-reported outcomes were assessed over 6 months.

Results

Twenty-four patients underwent surgery while one was lost to follow-up. The DN group showed significantly lower mean (SD) BR-R angular (3.58 [2.07] vs. 8.77 [4.20]°) and entry deviation (1.43 [0.51] vs. 2.01 [0.70] mm). For BR-D, the DN group had significantly lower angular (4.80 [2.62] vs. 12.97 [6.26]°), entry (1.45 [0.96] vs. 3.52 [1.54] mm), and apex deviation (1.28 [0.64] vs. 3.50 [1.47] mm) compared to the FA group. Implant angular deviation (3.74 [2.14] vs. 9.17 [4.39]°) and apex deviation (1.75 [0.44] vs. 2.35 [0.82] mm) was significantly lower in the DN group. In the FA group, one patient exhibited temporary lower lip hypoesthesia. No significant differences were observed in vertical bone gain, resorption, or patient-reported outcomes.

Conclusions

Compared to FA, DN may improve the accuracy of autogenous BRT procedures for vertical ridge augmentation while minimizing invasiveness.

评估动态导航对自体骨环技术垂直嵴增强的准确性和结果的影响：一项随机对照试验。

目的：自体骨环技术（BRT）是一种同时植入种植体的单阶段垂直增强方法。本研究的目的是比较动态导航（DN）辅助下的自体BRT与徒手入路（FA）用于垂直脊增强的准确性和有效性。材料和方法：24例符合自体BRT条件的患者随机分为DN组或FA组。两组术前均进行数字化设计。两组分别在DN辅助下或不辅助下进行BRT手术。准确度结果评估供体部位（BR-D）、受体部位（BR-R）骨环的角度和线性偏差，以及锥束计算机断层扫描显示的种植体进入/尖端与计划位置之间的偏差。垂直隆胸相关结果、手术并发症和患者报告的结果在6个月内进行评估。结果：手术24例，失访1例。DN组BR-R角均值（SD）（3.58[2.07]比8.77[4.20]°）和入线偏差（1.43[0.51]比2.01 [0.70]mm）显著降低。对于BR-D，与FA组相比，DN组的角度（4.80[2.62]比12.97[6.26]°），入口（1.45[0.96]比3.52 [1.54]mm）和顶点偏差（1.28[0.64]比3.50 [1.47]mm）显著降低。DN组种植体角偏差（3.74[2.14]比9.17[4.39]°）和尖偏差（1.75[0.44]比2.35 [0.82]mm）明显降低。在FA组中，一名患者表现出暂时的下唇感觉减退。在垂直骨生长、骨吸收或患者报告的结果方面没有观察到显著差异。结论：与FA相比，DN可以提高自体BRT垂直嵴增强手术的准确性，同时减少侵入性。试验注册：本研究在中国临床试验注册中心注册(https://www.chictr.org.cn；没有注册。ChiCTR2200065585;报名日期：2022/11/09)。
