Abstract

Background

Using the sandwich osteotomy technique in the posterior mandible is delicate. This study aimed to assess the safety and the amount of bone gain using a full digital workflow versus the conventional procedure.

Patients and methods

This split mouth study included 10 patients with bilateral vertically deficient posterior mandible. One side received conventional sandwich interpositional bone grafting (control group), while the other side received the same protocol using two patient-specific guides. The first guide (cutting guide) was used to place the osteotomies safely and accurately according to the predetermined dimensions and locations, and the second guide was used to fix the mobilized bony segment, leaving the desired gap to be filled with a particulate xenogenic bone graft.

Results

Full neurosensory recovery was documented at 2 months postoperative for all patients and bilaterally. After 4 months, there was a statistically significant difference in vertical bone gain between both groups (p = 0.001), measuring an average of 3.76 ± 0.72 mm in the study group and 2.69 ± 0.37 mm in the control group. No statistically significant difference was found between the planned vertical augmentation (3.85 ± 0.58 mm) and the obtained vertical bone gain (3.76 ± 0.72 mm) in the study group (p = 0.765) proving the accuracy of the guided procedure.

Conclusion

Computer-guided sandwich interpositional grafting is predictable regarding the execution of the osteotomies and the accuracy of fixation of the transport segment.

采用全数字化工作流程与传统方案对比，评估三明治截骨术治疗垂直缺损后下颌骨的骨增量和神经感觉：随机分口研究。

背景：在下颌后部使用三明治截骨技术是很微妙的。本研究旨在评估使用全数字化工作流程与传统手术的安全性和骨增量：这项分口研究包括10名双侧下颌后部垂直缺损的患者。一侧患者接受传统的三明治夹层植骨术（对照组），另一侧患者则使用两种患者专用的导板接受相同的方案。第一种导板（切割导板）用于按照预定的尺寸和位置安全准确地放置截骨，第二种导板用于固定被移动的骨段，留下所需的间隙，用颗粒状异种骨移植填充：结果：所有患者术后 2 个月双侧神经感觉完全恢复。4 个月后，两组患者的垂直骨增量差异有统计学意义（P = 0.001），研究组平均为 3.76 ± 0.72 mm，对照组平均为 2.69 ± 0.37 mm。研究组计划的垂直骨增量（3.85 ± 0.58 毫米）和获得的垂直骨增量（3.76 ± 0.72 毫米）之间没有明显的统计学差异（p = 0.765），证明了引导程序的准确性：结论：计算机引导下的三明治夹层植骨术在截骨的实施和运输段固定的准确性方面具有可预测性。

期刊介绍： The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
