Management of the protrusive premaxilla in patients with bilateral cleft lip is challenging for the reconstructive team. Several intra- and extraoral orthopedic techniques to reposition the protrusive premaxilla prior to bilateral cleft lip repair have been presented in the literature. A modification to a previously described tissue-borne palatal plate with a latex strap is presented. In the modified plate, the latex strap is replaced by an orthodontic elastomeric chain, and the chain over the prolabium is covered with soft denture liner. This appliance is effective in retracting the premaxilla, noninvasive, easy to construct and adjust, economic, well tolerated by the patient, and accepted by the parents.
对于重建团队而言，双侧唇裂患者前突前颌骨的管理颇具挑战性。文献中已介绍了几种在双侧唇裂修复术前重新定位前突前颌骨的口内和口外正畸技术。本文介绍了一种对先前描述的带有乳胶带的组织支持式腭板的改良方法。在改良后的腭板中，乳胶带被正畸弹性链取代，唇前的弹性链用软义齿衬垫覆盖。该矫治器能有效回缩前颌骨，无创，易于制作和调整，经济实惠，患者耐受性良好，且为家长所接受。
