I. Study materials : The 74 subjects consisting of 34 males from 40 to 76 years old and 40 females from 39 to 81, are devided into the three groups, that is, A, B and C groups. The A group consisting of 12 males and 11 females has been the experience since the subjects adapted the case of the complete dentures, were inserted the new ones by the author. The B group consists of the edentulous subjects (11 males, 14 females) having the experience in inserting the old ones. Furthermore, the C group is composed of the edentulous subjects (11 males, 15 females) having the experience from five to thirteen years. Both of B and C groups have been the denture experience since the new ones constructed by the author, were inserted. The A, B and C groups are classified by sex, and devided into under and over sixty ages groups by age. The new complete dentures inserted in the subjects, are constructed by the author with his hand, using the Okino's articulator and face-bow. The subjects are the complete dentures wearers having effectively carried out on the masticatory function, as the dentures were got to fit their mouth macous membrane after the adjustment. The measuring times in A group are before and after the insertion of the first complete dentures. That in B and C groups are before and after the insertion of the new ones. That in A, B and C groups after the insertion are eight times in total, i.e., third day, first week, second week, third week, first month, second month, third and six month. From the results of measuring by the method as mentioned above, the sample mean values and the confident intervals of mean values of population in 95% confidence conficient are computed at. The differences between the sample mean values are decided not to be significant, when there are nothing in common between the two confident intervals of that. II. Conclusions : 1. The total mean value of the sensory threshold before the insertion in A group is lower than that in B group and C groups. Therefore, the sensitivity of the mucous membrane in B and C groups is less dulled than that in A group. The confident difference of each sensory thre shold value between Band C group is not significantly recognized. 2. Each total mean value of that in A, B and C groups decreases gradually after the insertion. After its value once showes minimum decrease, and increase slowly on the other hand. This chance in A group is after second month, in B group after first month and in C group after third week. Order of the degrees of shortness in the latent period is the first dentures wearer, the short and longer experience wearing of dentures. But, regarding each threshold value, there are significant differences between A and B, C group, however, the difference between B and C groups is not significant. 3. Regarding the total mean value of that in each measuring time after the insertion, A group is higher than B group and B group higher than C group. According to the experience of dentures is lengthened, the sensitivity of mucous membrane becomes to be dulled. 4. The total mean value of that in each group for sixth month after insertion is the same valueas that before the insertion. It is pointed that the sensitivity of that recovers to be the same value before insertion. 5. In common to every measuring times in A, B and C groups, the sensitivity of that in male has tendency of being less dulled. Furthermore, that under sixty ages has tendency of being more active than that over sixty.
