[Masticatory rhythms in persons wearing a postsurgical complete denture (using 4-META resin and improved press-plate) as observed on EMG and MKG].

A postsurgical upper complete denture was constructed with metal press-plate specially improved for applying the acrylic resin containing 4-META in the hemimaxillary edentulous patient. The whole process of denture construction is described and the resultant denture effect is evaluated by our test method in this paper. The main findings are: 1. The internal surface is quite smooth and clean 2. Due to the thinness (0. 4 mm) the denture is not heavy and is almost the same as an acrylic resin denture 3. Bonding of the acrylic resin to the metal press-plate is strong In order to evaluate the acceptability of this prosthesis, masticatory rhythms were analyzed by means of EMG and MKG. The results showed that the rhythms were similar to the group wearing a normal complete denture and it is considered that this prosthesis functioned well during mastication.
