Abstract

Background

Guided bone regeneration (GBR) is a predictable approach for managing severe alveolar ridge deficiencies prior to implant placement. Resorbable collagen membranes supported by tenting screws are widely used, although space maintenance in non-contained defects may be challenging. Customized CAD/CAM titanium meshes have been introduced to enhance graft stability and surgical workflow, but comparative clinical evidence remains limited.

Objective

To compare clinical, radiographic, procedural, and peri-implant outcomes of customized CAD/CAM titanium meshes versus resorbable collagen membranes supported by tenting screws for horizontal and/or vertical alveolar ridge augmentation.

Materials and Methods

This retrospective study included 40 patients with severe alveolar ridge defects, allocated to two groups (n = 20 each). Both groups received particulate bone grafts stabilized either with tenting screws and a resorbable collagen membrane or with a patient-specific CAD/CAM titanium mesh. Cone-beam computed tomography (CBCT) scans at baseline and 6 months were used to assess vertical and horizontal bone gain. Intraoperative time, complications, pseudo-periosteum formation, implant survival, and peri-implant marginal bone levels at prosthetic loading and at 5-year follow-up were recorded.

Results

At 6 months, mean bone height reached 8.7–8.93 mm in the maxilla and 9.25–9.35 mm in the mandible, while mean ridge width ranged from 4.7 to 5.3 mm, with no significant intergroup differences (p > 0.05). Mean peri-implant marginal bone loss was limited and remained stable from prosthetic loading to the 5-year follow-up in both groups. Mean operative time was significantly shorter in the customized mesh group, 72.7 min (range: 60–85) for the Tent-pole group and 62.4 min (range: 60–65) for the Ti-mesh group. All 60 implants placed in 40 augmented sites survived, with no implant failures and no need for additional grafting procedures.

Conclusions

Both GBR techniques provided comparable bone regeneration and long-term peri-implant stability, while customized CAD/CAM titanium meshes were associated with reduced operative time.

定制钛网与螺钉-帐篷杆移植术的临床和影像学结果：回顾性研究。

背景：引导骨再生（GBR）是治疗种植体植入前严重牙槽嵴缺陷的可预测方法。可吸收的胶原膜支持的帐篷螺钉被广泛使用，尽管空间维护的非包含缺陷可能是具有挑战性的。定制CAD/CAM钛网已被引入，以提高移植物的稳定性和手术流程，但比较临床证据仍然有限。目的：比较定制CAD/CAM钛网与支架螺钉支持的可吸收胶原膜在水平和/或垂直牙槽嵴增强中的临床、影像学、手术和种植周围效果。材料与方法：回顾性研究40例重度牙槽嵴缺损患者，分为两组，每组20例。两组患者均接受颗粒骨移植物，用帐篷螺钉和可吸收胶原膜或患者专用CAD/CAM钛网固定。锥形束计算机断层扫描（CBCT）在基线和6个月时用于评估垂直和水平骨增重。记录术中时间、并发症、假骨膜形成、假体存活、假体装填和5年随访时种植体周围边缘骨水平。结果：6个月时，上颌平均骨高为8.7 ~ 8.93 mm，下颌骨平均骨高为9.25 ~ 9.35 mm，脊宽为4.7 ~ 5.3 mm，组间差异无统计学意义（p < 0.05）。两组的平均种植体周围边缘骨损失有限，并且从假体装载到5年随访期间保持稳定。定制补片组的平均手术时间明显缩短，Tent-pole组为72.7 min（范围：60-85），ti补片组为62.4 min（范围：60-65）。所有放置在40个增强部位的60个植入物都存活了下来，没有植入物失败，也不需要额外的移植手术。结论：两种GBR技术提供了相当的骨再生和长期种植体周围稳定性，而定制的CAD/CAM钛网可减少手术时间。

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.
