目的
本研究旨在探讨下颌剩余牙槽嵴形态对全口义齿患者咀嚼能力的影响。
方法
受试者组由199名全口义齿佩戴者组成。使用重体硅橡胶印模材料获得的牙槽嵴复制品对每个受试者的下颌骨剩余牙槽嵴进行评价。用数字化仪测量每个复制品的基底面积。还计算了每个复制品的体积和高度。采用25项食物摄入量调查表对受试者的咀嚼能力进行评价。计算每个受试者的咀嚼评分以代表咀嚼能力。根据基底面积的大小将所有受试者分为S、M、L三组。
结果
剩余牙槽嵴底面积与咀嚼功能评分之间存在显著相关性（r = 0.366，p <0.01），剩余牙槽嵴体积与咀嚼功能评分之间存在显著相关性（r = 0.314，p <0.01）。L组（29人）的剩余牙槽嵴底面积、剩余牙槽嵴体积和咀嚼评分均显著大于M组（136人）和S组（34人）（p <0.05），M组的这些值显著大于S组（p <0.05）。
结论
结果表明，下颌基托基底面积对全口义齿患者的咀嚼能力有一定的影响。
PURPOSE
The purpose of this study was to investigate the influence of mandibular residual ridge shape on the masticatory ability in complete denture wearers.
METHODS
The subject group consisted of 199 complete denture wearers. The mandibular residual ridge of each subject was evaluated using a replica of the ridge which was obtained with heavy-body silicone impression material. The basal area of each replica was measured with a digitizer. The volume and the height of each replica were also calculated. The masticatory ability of each subject was evaluated using a-25-item food intake questionnaire method by authors. The masticatory score of each subject was calculated to represent the masticatory ability. Furthermore, all subjects were divided into three groups (S, M, L group) according to the value of the basal area.
RESULTS
There were statistically significant correlations between the basal area of the residual ridge and the masticatory score (r = 0.366, p < 0.01), and also the volume of the residual ridge and the masticatory score (r = 0.314, p < 0.01). The basal area of the residual ridge, the volume of the residual ridge, and the masticatory score of the L group (29 persons) were statistically larger than those of the M group (136 persons) and the S group (34 persons) (p < 0.05), and those values in the M group were statistically larger than those of the S group (p < 0.05).
CONCLUSION
It was confirmed that the basal area of denture foundation of the mandible had an influence on the masticatory ability in complete denture wearers.
