INFLUENCE OF DENTURE ADHESIVES ON ORAL HEALTH QUALITY OF LIFE , OCCLUSION AND DISOCCLUSION TIMESOF DIGITALLY FABRICATED AND DESIGNED REMOVABLE COMPLETE DENTURES (CLINICAL CROSS OVER STUDY)

Background: The efficiency of adhesives in enhancing the retention of complete denture has been well recognized.Yet the correlation of using adhesives with occlusal equilibration has not been investigated especially after introducing digitally fabricated complete dentures in order to overcome the drawbacks of the conventional processing technique of complete dentures.In addition, the competence of the prosthesis and its ability to improve the quality of life of the patient should be given great attention as improvement of patient`s life is the main goal of any medical intervention. Objective:The purpose of this crossover clinical study was to evaluate the influence of using adhesives with the digitally fabricated (3D printed) dentures on occlusal equilibrationandOral Health Quality of Life (OHRQoL) Materials and Methods: The Study was designed as crossover clinical trial, total of 27 subjects participated in the study, all the patients received digitally fabricated (3D Printed)set of complete dentures First: The patients were instructed to wear the complete denture for the first two weeks after that occlusal equilibration was evaluated in terms of occlusion time (OT) and dis-occlusion time (DT). Second: After two weeks the patients were instructed to use the same (3D printed) complete denture for another two weeks after application of denture adhesive then occlusal equilibration was evaluated again in terms of occlusion time (OT) and disocclusion time (DT). Oral Health-related Quality of Life (OHQoL) questionnairewas used to evaluate the patient satisfaction at the end of the follow up period of each denture set. Results:Regarding occlusion time,there was significant difference for all timings as mean ± standard deviation without adhesive and with adhesive were (0.56±0.018) and (0.31±0.024) respectivelyas P-value < 0.05.Regarding oral health effect on the quality of life, the studied domains revealed a significant improvement after adhesive application as the denture with adhesive showed lower scores than without adhesive. Conclusion: Within the limitations of this study and the given specific patient population, denture adhesives were found to significantly reduce occlusion time (OT) and disocclusion time (DT) durations in CAD/CAM complete dentures with fairly balanced occlusion, further improving denture stability and the patients Oral Health Quality of Life.
