Intra-operator reliability for the evaluation of the retention of maxillary denture bases constructed through close mouth impression technique

ABSTRACT

This study was conducted to establish the reliability of the results by three operators for evaluation of retention in maxillary denture bases constructed by closed mouth impression technique. A cross-sectional comparative study was carried out in the Department of Prosthodontics, de, Montmorency College of Dentistry/ Punjab Dental Hospital, Lahore.

Denture base constructed by closed mouth impression technique was evaluated by three operators in the anterior, right and left canine area using Kapur index.3 Results were analyzed and compared using descriptive statistical analysis protocol. In 73.97% of the results, retention of upper complete denture base constructed through closed mouth technique showed the intra operator reliability. Intra operator reliability was seen among the results showing retention of the upper complete denture base constructed through closed mouth technique
