The purpose of the study was to evaluate the magnitude of ridge augmentation with titanium mesh, overall graft success, anatomic location of ridge defects and their relationship to mesh exposure.
This retrospective study evaluated 44 patients who received mandibular or maxillary reconstruction with autogenous particulate bone graft and titanium mesh for the purpose of implant placement. Autogenous bone graft was harvested from the iliac crest, tibia, and mandibular symphysis. A total of 45 sites were included in the study. Average augmentation bone heights were measured and compared. Statistical analysis was done with ANOVA and Student's t test. Histomorphometric analysis was performed on the soft tissue specimen found between the mesh and the bone graft.
Twenty-nine sites underwent mandibular reconstruction and 16 underwent maxillary reconstruction. The mean augmentation in partial maxillary defects was 11.33 +/- 1.56 mm, and in complete maxillary augmentation, the height achieved was 14.3 +/- 1.39 mm. In the mandible, mean increase in height for partial defects was 14 +/- 1.42 mm and for complete augmentation it was 13.71 +/- 1.14 mm. The mean augmentation for all sites was 13.7 mm (12.8 mm in the maxilla and 13.9 mm in the mandible). A total of 82 implants were placed in the maxilla and 92 implants were placed in the mandible. In the maxillary group, 7 sites had exposure of the titanium mesh and 16 sites were exposed in the mandible. The success of the bone grafting procedure was 97.72%.
Porous titanium mesh is a reliable containment system used for reconstruction of the maxilla and the mandible. This material tolerates exposure very well and gives predictable results.
本研究旨在评估钛网增高牙槽嵴的程度、整体植骨成功率、牙槽嵴缺损的解剖位置及其与钛网暴露的关系。
本回顾性研究评估了44例接受自体颗粒骨移植和钛网进行下颌或上颌重建以植入种植体的患者。自体骨取自髂嵴、胫骨和下颌联合处。本研究共纳入45个部位。测量并比较平均增高骨高度。采用方差分析和学生t检验进行统计分析。对钛网与骨移植之间的软组织标本进行组织形态计量分析。
29个部位进行了下颌重建，16个部位进行了上颌重建。部分上颌骨缺损的平均增高为11.33±1.56mm，完全上颌骨增高时达到的高度为14.3±1.39mm。在下颌骨中，部分缺损的平均高度增加为14±1.42mm，完全增高时为13.71±1.14mm。所有部位的平均增高为13.7mm（上颌骨为12.8mm，下颌骨为13.9mm）。上颌骨共植入82枚种植体，下颌骨植入92枚种植体。在上颌骨组中，7个部位出现钛网暴露，下颌骨有16个部位暴露。骨移植手术的成功率为97.72%。
多孔钛网是一种用于上颌骨和下颌骨重建的可靠容纳系统。这种材料对暴露耐受性良好，结果可预测。
