title: Asymptomatic hypoesthesia of the maxillary alveolar ridge in complete denture wearers.
abstract: This study was carried out to investigate the effect of compression induced by complete dentures on the function of the nerves underlying the dentures. The influence of compression induced by complete dentures on nerve function was analysed using current perception threshold (CPT) in 33 complete denture wearers aged 50-80 at Nihon University School of Dentistry (Matsudo, Japan). Based on the age range of the complete denture group, dentate subjects were selected as a control. Because the group characteristics (such as subject age, gender, body mass index) and oral mucosal thickness were not matched, a multiple regression analysis was used to adjust for the influence of heterogeneous characteristics on the CPT. Statistically significant differences were found between subject groups for the nasopalatine and the greater palatine nerve. The results of the study were that complete denture wearers experience asymptomatic hypoesthesia mainly affecting the nasopalatine and greater palatine nerves, but not the infraorbital nerve.
