Objective: To explore the clinical effects of treatment denture on difficult edentulous cases before complete denture restoration.
Methods: Thirty-six patients who experienced unsuccessful restoration of conventional complete dentures were included in this study. Treatment dentures were fabricated to solve issues such as abnormal occlusion, tissue surface problems, and neuromuscular dysfunction of the stomatognathic system caused by systemic diseases. The final complete dentures were fabricated by duplicating the treatment dentures. Jaw relation index, stability, and retention were evaluated at different stages. Oral health-related quality of life was measured using the Chinese version of Oral Health Impact Profile for edentulous subjects (OHIP-EDENT).
Results: Among the 36 patients, 33 successfully completed the final restoration with positive effects.
Conclusions: Treatment denture is an effective pre-restorative option that can be used to correct abnormal occlusion, improve tissue surface problems, and aid in neuromuscular rehabilitation training. Treatment dentures contribute to the successful restoration of the final complete dentures and is worthy of clinical applications.
目的 探讨治疗义齿在疑难全口义齿修复前的临床应用价值。方法 选择36例疑难全口病例修复困难或失败的患者，针对修复困难或失败的原因，应用治疗义齿改善不利于义齿修复的多种因素，通过治疗义齿复制，完成最终义齿修复。采用颌位关系指数、固位力及稳定性评分、口腔健康影响程度-EDENT量表评价治疗过程的有效性。结果 36例患者中，33例患者获得有效治疗，顺利完成最终义齿修复，且修复效果良好。结论 治疗义齿是一种行之有效的治疗方法，能纠正咬合和黏膜面问题并作为口颌系统神经及肌肉康复训练的工具，有助于最终义齿修复，值得临床推广和应用。.
