Abstract :

Various physical changes causes alterations in the fit of the denture. Since most of the recipients of the complete denture prosthesis are the geriatric population,a time saving procedure is paramount for the satisfaction of the patient. Thus the need for dimensionally accurate relining and rebasing was established . This study estimates the changes in the linear dimensions of 28 dentures before and after relining and rebasing. Two groups with 14 dentures each for relining and rebasing were selected .Pre reline and pre–rebase measurements were recorded .Impressions were recorded using closed mouth technique. Post reline and post rebase measurements were recorded. The collected data was statistically compared and analyzed. Statistically significant variation was seen in change of dimensions compå reline and rebase. The dimensional differences between pre and post reline/rebase did not hinder the attained support and retention of the denture. Relined and rebased dentures had negligible variations
