抄録

Various types of occlusal scheme have been developed for a complete denture. Some investigators recommended lingualized occlusion as the scheme of occlusion for acomplete denture, but how to determine the buccal interocclusal distance in lingualized occlusion isunclear. The purpose of this study was to investigate the influence of the buccal interocclusal distance in lingualized occlusion on the pressure distribution under a complete denture. In this study, eight pressure transducers were placed in the basal surface of a mandibular denture. The pressure distribution under a complete denture and the required force were recorded when crushing three different foods: kamaboko, carrot, and peanuts.<BR>The results were as follows:<BR>1. The required force for crushing all test foods decreased as the buccal interocclusal distance increased.<BR>2. During the food crushing tests the positive pressure values were observed mainly on the working side and the positive pressure values decreased as the buccal interocclusal distance increased.<BR>3. The negative pressure values were observed on the non-working side, and the negative pressure values decreased as the buccal interocclusal distance increased.<BR>4. The required force for crushing test foods and the pressure applied to supporting tissues greatly decreased when crushing hard foods.
