Reconstruction of segmental defects and the atrophic maxilla and mandible is performed using various techniques. Bone substitutes have received a wealth of reports in the literature demonstrating a long-term success when used in alveolar bone augmentation procedures.
We reviewed articles comparing TiMesh GBR technique with different percentage of bone: autogenous bone alone (AB); anorganic bovine bone alone (ABB); 50:50 or 70:30. From an initial pool of 122, we selected 14 studies. ANOVA followed by Tukey HSD test was used for statistical analysis.
We present a table analysing fundamental parameters to value a successful GBR therapy. Autogenous bone remains the gold standard in GBR technique with TiMesh; however, the combination between AB/ABB in relation 50:50 and 70:30 allows reducing surgical cost exploiting properties of eterologous bone.
The use of autologous bone is associated with a height and width gain of bone, which are greater compared to other techniques, with a lower exposure of the mesh and a lower bone resorption. The use of heterologous graft leads to a lower bone earn and to percentage of resorption greater than autologous graft but does not differ from the gain and resorption of the bone of AB/ABB in percentage 50:50 and 70:30.
采用多种技术对节段性骨缺损以及萎缩性上颌骨和下颌骨进行重建。骨替代物在文献中已有大量报道，表明其用于牙槽骨增量手术时具有长期的成功效果。
我们回顾了比较TiMesh引导骨再生技术与不同比例骨的文章：单纯自体骨（AB）；单纯无机牛骨（ABB）；50:50或70:30比例。从最初的122篇文章中，我们筛选出14项研究。采用方差分析及后续的Tukey HSD检验进行统计分析。
我们列出了一个表格，分析评估引导骨再生治疗成功的基本参数。在使用TiMesh的引导骨再生技术中，自体骨仍是金标准；然而，50:50和70:30比例的AB/ABB组合利用异体骨的特性可降低手术成本。
使用自体骨与骨高度和宽度的增加相关，与其他技术相比增加幅度更大，网片暴露率更低，骨吸收更少。使用异体移植物导致骨增量较低，吸收百分比高于自体移植物，但与50:50和70:30比例的AB/ABB骨增量和吸收情况无差异。
