A removable complete denture is the only proven non-invasive treatment modality that is readily available to an edentulous patient and should be made in such a manner that these feel at home in the mouth of the individual.All dentures which depend on edentulous ridge areas for all or part of their support must be accepted as temporary dental restorations. This is because edentulous ridge areas continue to decrease in size throughout the life of the patient. All denture wearers should be advised of the importance of regular dental examinations and any necessary servicing if they are to obtain a maximum period of efficient service from such restorations.To maintain the prosthesis-tissue relationship, reline or rebase procedures are commonly required. Relining is the procedure in which the tissue side of the denture is resurfaced with new base material where as in rebasing entire denture base material is replaced with a new base material. The aim of this in-vivo study was to compare retention of maxillary denture bases before and after relining with different hard relining materials. MATERIALS AND METHODS The present study was conducted on twenty edentulous subjects, both males and females who reported in the Department of Prosthodontics, H.P Government Dental College, Shimla, Himachal Pradesh.The study was carried out in the following manner: 1.Evaluation of the patient 2.Fabrication of denture base from old denture. 3.Fabrication of cast from old denture 4.Duplication of cast I Background: The present study was to compare the retentive qualities of two hard chair side relining materials on maxillary denture base, and compare the retention of relined and un-relined denture. Material and method: Twenty healthy subjects with edentulous maxillary ridge and good oral hygiene and a complaint of loose denture were selected as a part of this study. After using the old denture as denture base, three new denture bases were fabricated for each subject and then these denture bases were relined using materials B and C. A specially designed retention apparatus consisting compact force gauge was used to measure the retention values of denture bases before and after relining with three hard chair side relining materials. Results:There was a statistically significant increase in retention of denture bases after relining with material B, C as compared to the retention of old denture base (A). Among all the relining materials, material (C) has shown best results.Conclusion: Relining the denture bases with hard reliners significantly improved the retention of the denture base. Further studies with time based functional analysis on clinical performance of hard relining agents especially as related to colour stability, resistance to fracture and surface condition are required.
