研究目的:

种植区骨量不足是影响种植效果的关键因素,牙槽骨垂直骨吸收的患者骨缺损修复尤为困难。近年来,GBR技术逐渐成为骨缺损修复的常规技术,但目前临床上常用GBR膜均存在无足够机械强度导致成骨空间塌陷、骨吸收等问题。个性化3D打印钛网单独或联合生物膜被逐渐应用于大面积垂直骨缺损,其具有良好的机械性能,可精准设计骨增量的体积和外形。但是钛网较易暴露,造成成骨量明显下降,需二次手术取出。通过不同技术及方法打印3D羟基磷灰石(HA)支架并应有于骨再生取得了巨大的成功。立体光刻技术(SLA)已被证明是制造具有复杂结构的3D陶瓷零件的高性能工艺。鉴于前期我们课题组打印许多复杂HA三维支架,其证实其良好的生物学性能并取得较好的实验效果。通过CT影像数据及计算机软件设计的3D打印个性化HA屏障膜,具有精确的骨表面拟合性能及精准的骨增量轮廓和体积,且不用二次手术取出,减低并发症的发生,成为治疗该类临床疾病的创新性新技术,并且推动相关上游产业的发展。  

Objectives of Study:

Bone deficiency in the planting area is the key factor affecting the implant effect, and bone defect repair is particularly difficult for patients with vertical bone absorption of alveolar bone. In recent years, GBR technology has gradually become a conventional technique for bone defect repair. However, currently, GBR membrane in common clinical practice has problems such as lack of sufficient mechanical strength leading to osteogenic space collapse and bone absorption. Personalized 3D printed titanium mesh alone or in combination with biofilm has been gradually applied to large vertical bone defects. With good mechanical properties, the volume and shape of bone increment can be precisely designed. However, titanium mesh is easy to be exposed, resulting in a significant decline in bone formation, requiring a second operation. Printing 3D hydroxyapatite (HA) scaffolds with different techniques and methods has achieved great success in bone regeneration. Stereo lithography (SLA) has proven to be a high-performance process for manufacturing 3D ceramic parts with complex structures. In view of the fact that our research group printed many complex HA 3D scaffolds in the early stage, it confirmed its good biological performance and achieved good experimental results. By CT image data and computer software to design the 3 d print personalized HA barrier membrane, has a precise bone surface fitting performance and precision of bone incremental contour and the volume, and don't have to out the second operation, reduce the occurrence of complications, become innovative new technology in the treatment of the clinical diseases, and to promote the development of upstream industry.
