Abstract

Purpose: To assess the radiographic and histomorphometric outcomes of horizontally augmented maxillary alveolar ridges using solid nonperforated customized titanium barriers.

Materials and methods: This case series study included patients who received guided bone regeneration treatment in the anterior maxillary esthetic zone (eight patients, 18 dental implants) using patient-specific solid titanium barriers loaded with a mix of autogenous and xenogenic particulate bone grafts. A radiographic comparison between three time periods (immediately postoperative, 4 months, and 10 months) included software-aided calibration of the linear changes in the horizontal dimensions on CBCT cross-sectional cuts after being standardized. Bone core specimens were retrieved for histomorphometric analysis by the time of implant insertion.

Results: Wound healing was uneventful, except for two patients who showed soft tissue breakdown that did not affect the outcome. There was a statistically significant difference between the mean horizontal bone change at the different time intervals (P < .001), with a 79.6% ± 29.2% mean area of newly formed bone.

Conclusion: GBR using customized solid titanium barriers appears to be efficient and promising concerning the final horizontal bone gain and the quality of the augmented sites.

使用患者特异性固体钛屏障引导的水平上颌牙槽嵴增强骨再生:一个案例系列
目的:评价非穿孔定制型固体钛屏障水平增强上颌牙槽嵴的影像学和组织形态学效果。材料和方法:本病例系列研究包括在上颌前美观区接受引导骨再生治疗的患者(8例患者,18颗牙种植体),使用患者特异性固体钛屏障加载自体和异种颗粒骨移植物的混合物。三个时期(术后立即,4个月和10个月)的x线片比较包括软件辅助校准CBCT横截切面标准化后水平尺寸的线性变化。在植入时取出骨芯标本进行组织形态学分析。结果:除两例患者出现软组织破裂外,伤口愈合顺利,不影响预后。不同时间间隔的平均水平骨变化差异有统计学意义(P < 0.001),平均新骨面积为79.6%±29.2%。结论:使用定制的固体钛屏障的GBR在最终的水平骨增加和增强部位的质量方面是有效和有前途的。

期刊介绍: Edited by Steven E. Eckert, DDS, MS ISSN (Print): 0882-2786 ISSN (Online): 1942-4434 This highly regarded, often-cited journal integrates clinical and scientific data to improve methods and results of oral and maxillofacial implant therapy. It presents pioneering research, technology, clinical applications, reviews of the literature, seminal studies, emerging technology, position papers, and consensus studies, as well as the many clinical and therapeutic innovations that ensue as a result of these efforts. The editorial board is composed of recognized opinion leaders in their respective areas of expertise and reflects the international reach of the journal. Under their leadership, JOMI maintains its strong scientific integrity while expanding its influence within the field of implant dentistry. JOMI’s popular regular feature "Thematic Abstract Review" presents a review of abstracts of recently published articles on a specific topical area of interest each issue.
