为固定下颌骨远端骨折片并恢复其功能,作者提出应用自凝塑胶帽状夹板进行治疗。优点是可以即刻完成,无需在技工室操作,在缺牙处设(牙合)垫以恢复功能。夹板制作方法任选印模材料,取下颌牙列印模,深度只达牙冠长度的1/3,于印模内放入调合好的自凝塑胶,再次进行印模,在硬固前取出,将塑胶部分修整磨平,即得到夹板雏形。在夹板上相当缺牙的部位,再放置自凝塑胶,根据正确的咬合关系形成(牙合)堤面。最后作重衬,磨平磨光后即告完成。
To fix the distal mandibular fracture and restore its function, the authors propose the use of self-plastic cap splint for treatment. The advantage is that it can be done instantly, without the need to operate in the technician's office, and to restore the function of the occlusal pad at the missing tooth. Plywood production methods Optional impression material, remove the jaw dentition impressions, the depth of only the crown length of 1/3, in the mold into a good blend of self-curing plastic, re-impression, in hard solid Remove, trim the plastic part polished, that plywood prototype. Patellar considerable lack of teeth in the site, and then place the self-setting plastic, according to the correct occlusion relationship (occlusion) embankment surface. Lastly, the lining is finished, polished and finished.
