患者一直未能较好的戴用义齿的原因:我们认为1980年,1987年所作上局义齿设计制作不妥,因为在戴用期间3次折断,使4Ⅲ°松动。患者一般体健,有心前区疼痛史,平日喜进硬食,患者的咀嚼肌群功能好,如果当时设计注意右侧增加支持,左侧缩小4～7颊舌径,将义齿尽量排在牙槽脊内侧与下颌牙成对刃(牙合),以上问题就不会出现。 The reason why patients have not been able to wear dentures well has been: We think the design of the dentures made in 1980 and 1987 is not suitable because of 3 breaks during wearing and 4 ° loosen. Patients generally have a healthy body, there is a history of pain in the anterior pituitary, happy to eat hard meals on weekdays, the patient's masticatory muscle function is good, if the design was to pay attention to the right to increase support for the left to narrow 4 ~ 7 buccal diameter, the denture as far as possible ranked in the teeth The inner side of the ridge and the mandibular teeth paired edge (occlusion), the above problems will not occur.
