目的探讨下牙槽嵴严重吸收的无牙颌全口义齿修复的固位和稳定方法。方法选择下牙槽嵴严重吸收的无牙颌患者41例,采用二次印模法,通过转移颌位关系、排牙、试牙、装合、去蜡、填胶等制作程序,而在制作过程中基托蜡形做成凹面形,填胶时义齿基托内安放金属网村。结果 41例患者均获得临床需要的固位要求,满意占90.2%,较满意占7.3%,一般占2.4%。修复效果良好。结论对于下牙槽低平且无牙颌患者总义齿修复时,唇颊基托做成凹面形,基托内加入金属网衬,加大基托的重量,增加了基托的附着力,提高了固位和稳定性,使患者感觉舒适。
Objective To investigate the method of retention and stabilization of maxillary complete dentures with inferior alveolar ridge absorption. Methods Forty-one edentulous patients with severe absorption of the alveolar crest were selected. The secondary impressions were made by transferring the jaw position, arranging teeth, trying out the teeth, fitting, dewaxing and filling. During the process, the base wax was made into a concave shape, and the metal mesh net was placed in the denture base when filling. Results All the 41 patients received clinically needed retention requirements, with 90.2% satisfaction, 7.3% satisfaction, and 2.4% overall. The repair effect is good. Conclusions For the total denture with low level and without edentulous mandibular alveolar, the cheek base made concave shape, and the metal mesh lining was added into the base to increase the weight of the base and increase the adhesion of the base, The retention and stability, so that patients feel comfortable.
