摘要/Abstract

摘要： 颞下颌关节（temporo-mandibular joint，TMJ）髁突生长的组织学核心机制是软骨内成骨，而髁突软骨的适应改建是SGTB（sagittal-guided twin block）矫形技术的生物学基础。对于含有颌位因素的突面畸形，SGTB通过下颌前导启动髁突适应性改建应答，使下颌稳定在新的位置，从而以重塑颌骨关系的治疗机制纠正深覆与深覆盖。SGTB等矫形技术诱发髁突改建的原理也可应用于颞下颌关节紊乱病（tempromandibular joint disorders，TMD）的治疗，通过部分修复病理性吸收的髁突及盘-突-窝关系的重构，达到缓解或抑制TMD的目标。

Abstract: Endochondral ossification constitutes biological and phenotypic foundation for condylar growth. Adaptive response of condylar cartilage to mandibular advancement, on the other hand, facilities condylar remodeling generated by SGTB （sagittal-guided twin block）orthopedic therapy. This enables SGTB to correct increased overjet and overbite by eliminating jaws discrepancy. It is also an encouraging advance that SGTB therapy is used to intervene temporo-mandibular joint disorders (TMD) by regenerating the degraded condylar cartilage.

Key words: Condylar cartilage, Adaptive remodeling, SGTB orthopedics, Facial prognathism
