This clinical report illustrates how an active traction appliance was made for a patient with severe microstomia by attaching custom-made lip retractors to an orthodontic headgear. A steady, light tensile force was imparted to the lips with the elastic bands between the retractors and the headgear.
本临床报告展示了如何通过将定制的唇部牵开器连接到正畸头帽上,为一名患有严重小口畸形的患者制作一种主动牵引装置。通过牵开器与头帽之间的弹力带,对唇部施加稳定、轻柔的拉力。
