The purpose of the present study was to determine the rate and extent of complications associated with using titanium mesh for bone regeneration and to identify which factors might be associated with postoperative complications, such as infection, soft tissue exposure, and graft failure.
A retrospective study design was used to analyze the treatment outcomes of 27 consecutive surgical sites in the maxilla and mandible that were treated with bone grafting in conjunction with fixation of titanium mesh. The primary study variable was whether the surgical sites treated with titanium mesh presented with any postoperative complications such as exposure of the titanium mesh and/or graft failure. A secondary study variable was whether treatment with bone grafting and fixation of titanium mesh provided the necessary bone augmentation required for subsequent dental implant placement. The predictor variables of maxillary versus mandibular surgical site and the type of bone graft material used were studied to determine whether any relationship exists between these variables and the aforementioned postoperative complications.
A total of 27 consecutive sites in the maxilla and mandible that required substantial bone augmentation and were treated with titanium mesh were evaluated for 6 to 24 months after surgical treatment. Exposure of titanium mesh was seen in 7 (26%) of the 27 surgical sites evaluated. No significant difference in the exposure rate was seen between the maxilla and mandible or according to the type of graft material used. All 69 implants placed were in function, and the success rate was 100%.
The findings from the present study indicate that substantial bone augmentation can be achieved using titanium mesh in conjunction with bone grafting. Furthermore, exposure of titanium mesh during healing does not necessarily compromise the final treatment outcome.
本研究旨在确定使用钛网进行骨再生相关并发症的发生率和程度，并确定哪些因素可能与术后并发症相关，如感染、软组织暴露和移植失败。
采用回顾性研究设计，分析上颌骨和下颌骨连续27个手术部位的治疗结果，这些部位采用骨移植联合钛网固定治疗。主要研究变量是接受钛网治疗的手术部位是否出现任何术后并发症，如钛网暴露和/或移植失败。次要研究变量是骨移植联合钛网固定治疗是否提供了后续牙种植体植入所需的必要骨增量。研究上颌与下颌手术部位以及所用骨移植材料类型的预测变量，以确定这些变量与上述术后并发症之间是否存在任何关系。
对27个上颌骨和下颌骨连续部位进行了评估，这些部位需要大量骨增量并采用钛网治疗，术后随访6至24个月。在评估的27个手术部位中，有7个（26%）出现了钛网暴露。上颌骨和下颌骨之间或根据所用移植材料类型，暴露率无显著差异。所有植入的69颗种植体均功能良好，成功率为100%。
本研究结果表明，钛网联合骨移植可实现大量骨增量。此外，愈合过程中钛网暴露不一定会影响最终治疗结果。
