Abstract
This paper reports the comparison of impression design between the following two techniques: an open-mouth impression technique with a provider centric approach, which is a mandibular complete denture impression technique involving border molding for separate blocks with the use of a compound; and an impression technique with a patient centric approach, which involves impression molding in a closed-mouth position during which the patient himself/herself is allowed to perform functional jaw movement for the attachment by suction of a mandibular complete denture. The results for comparison and observation revealed that there are characteristic differences relative to individual parts in the mouth. Based on such characteristics, it is suggested that the impression technique with a provider centric approach is focused on the support of a mandibular denture and thus is intended to extend a denture base while keeping the supporting tissue free from functional problems, and that the impression technique with a patient centric approach involves the attachment by suction of a mandibular complete denture to residual ridges and thus is intended to sufficiently fill a defect space with a denture.
