role of periodontal receptors during learning period of denture wearing

ABSTRACT

A study was conducted to investigate the role of periodontal receptors in sensory input and muscles activity during a learning period of denture wearing. Six volunteers were treated at first with maxillary complete dentures and m and ibular overdentures with canine or premolar serving as abutments on each side. The abutment teeth were then extracted, reimplanted and submerged. EMG activity of the muscles and proprioceptive studies were carried out within the first week of dentures insertion before and after reimplantation of teeth. Results showed that there was a significant decrease in EMG activity of the muscles and a reduction in sensory input of the patients after reimplantation of teeth
