Abstract

Background

The horizontally insufficient posterior mandibular ridge frequently restrains dental implant insertion.

Patients and Methods

A modified ridge split procedure was innovated to separate, convey laterally, and fix the buccal cortical plate in 20 patients with posterior horizontal mandibular alveolar deficiency. Meanwhile, the intercancellous space was obliterated with autogenous bone particulates for the test group patients and Anorganic bone bovine mineral (ABBM) for those of the control group. Following a comparison of the horizontal bone gain and the histomorphometric bone area percent among both groups after 6 months of graft consolidation, 40 implants were inserted during the second surgical stage.

Results

All of the grafts were consolidated. A statistically insignificant difference was found between the control group's mean 6-month postoperative horizontal bone width of (8.10 ± 0.83) and that of the study one of (7.90 ± 0.77). The control group's mean bone gain was recorded (4.76 ± 0.81) versus (4.63 ± 0.78) for the study group, with a statistically insignificant difference. Both groups showed histological evidence of a moderate number of osteoblasts, mature trabecular bone, and lamellae encircling large fatty marrow spaces. A statistically significant difference (p = 0.021) was found between the control group's mean bone area percentage of new bone formation (38.83% ± 1.17%) and that of the study group (34.40% ± 3.71%).

Conclusion

The modified ridge split with either autogenous or (ABBM) graft was deemed reliable for reconstructing the horizontally deficient posterior alveolar ridge with appropriate volumetric stability and bone quality.

评估改良脊裂与自体与异种增强：随机临床试验

背景下颌骨后嵴水平不足是制约种植体植入的常见原因。对20例下颌后水平牙槽缺损患者采用改良脊裂法分离、侧移、固定颊皮质钢板。与此同时，实验组和对照组分别用自体骨颗粒和无机骨牛矿物（ABBM）填塞松质间隙。比较两组在植骨巩固6个月后的水平骨增重和组织形态学骨面积百分比后，在第二手术阶段插入40个植骨体。结果所有移植物均得到巩固。对照组术后6个月平均水平骨宽度为（8.10±0.83），实验组术后6个月平均水平骨宽度为（7.90±0.77），差异无统计学意义。对照组平均骨增重为（4.76±0.81），研究组平均骨增重为（4.63±0.78），差异无统计学意义。两组均有组织学证据显示成骨细胞数量适中，骨小梁成熟，片层环绕大脂肪骨髓间隙。对照组平均骨面积新生骨形成率（38.83%±1.17%）与研究组平均骨面积新生骨形成率（34.40%±3.71%）比较，差异有统计学意义（p = 0.021）。结论改良牙槽嵴劈开与自体或（ABBM）移植均可有效重建水平缺损的后牙槽嵴，具有良好的体积稳定性和骨质量。试验注册：在www.clinicaltrials.gov上注册（注册号：NCT05286541）

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.
