目的观察圆锥型套筒冠义齿对中老年患者牙列缺损伴有重度磨耗进行咬合重建的临床疗效。方法通过对21例有牙列缺损且伴有重度磨耗的中老年人辅以俄亥俄型咬合板、圆锥型套筒冠义齿等序列治疗,重建中老年人咬合功能。客观临床检查及问卷调查患者主观满意度。结果经过圆锥型套筒冠义齿等序列咬合重建治疗,患者主观感觉满意,修复前牙周膜增宽的基牙,修复后牙周膜宽度基本恢复正常,修复后基牙牙槽嵴顶高度未见降低,部分角形吸收牙槽骨可见牙槽嵴顶高度增加。结论圆锥型套筒冠义齿可有效地重建正常的咬合关系,使口颌系统恢复正常的生理功能,对中老年伴有重度磨耗的牙列缺损的患者是一种较为理想的修复方法。
Objective To observe the clinical effect of cone-shaped canopy dentures on occlusion reconstruction of dentition defects with severe abrasion in middle-aged and elderly patients. Methods The occlusion function of middle-aged and elderly patients was reconstructed by treating 21 middle-aged and elderly patients with dentition defect and severe abrasion supplemented with Ohio-type occlusal plate and conical sleeve denture. Objective clinical examination and questionnaire subjective satisfaction. Results After the conical sleeve denture and other sequence occlusion reconstruction treatment, the patient subjective feeling satisfied, repair anterior periodontal ligament broaden the width of the periodontal ligament after repair basically returned to normal, the alveolar crest height of the abutment was not restored Lower part of the angular absorption of alveolar bone showed alveolar crest height increased. Conclusion Conical telescopic crown denture can effectively rebuild the normal occlusal relationship and make the oral and maxillary system return to normal physiological function. It is an ideal method for the repair of dentition defect in middle-aged and elderly patients with severe wear.
