In the treatment of orthodontic patients with idiopathic condylar resorption, symptoms of temporomandibular joint disorders and constantly changing occlusions caused by an instability of mandibular position make it difficult for orthodontists to confirm definitive orthodontic diagnosis and treatment plans. Therefore, these patients' temporomandibular joint (TMJ) structures need to be stabilized with splint therapy before active tooth movement to identify and maintain the true mandibular position. For some idiopathic condylar resorption patients, orthognathic surgery can cause further resorption on the vulnerable condyles of the mandible; thus, effective orthodontic camouflage treatment after joint stabilization should be considered. During the orthodontic camouflage treatment, adverse loads on the TMJ structures, which could change the position of condyles, should be avoided, and TMJ-friendly mechanics must be applied.
在治疗特发性髁突吸收的正畸患者时，由于颞下颌关节紊乱症状和不断变化的咬合关系（由下颌位置不稳定引起），正畸医生难以确定明确的正畸诊断和治疗计划。因此，这些患者的颞下颌关节（TMJ）结构需要在主动牙齿移动之前通过夹板治疗来稳定，以确定并维持真正的下颌位置。对于一些特发性髁突吸收患者，正颌手术可能会导致下颌脆弱的髁突进一步吸收；因此，关节稳定后应考虑进行有效的正畸掩饰治疗。在正畸掩饰治疗过程中，应避免 TMJ 结构承受可能改变髁突位置的不利负荷，并应采用对 TMJ 友好的力学。
