ABSTRACT: Introduction: Denture technology is constantly moving forward and providing denture wearers with better and better options for denture comfort and fit. There are some products and systems in the market that will raise the denture retentionAim: (1) To fabricate an innovative suction device [Unidirectional air flow device] (2) To assess the effectiveness of innovative suction device on retention of maxillary complete denture. Materials and methods Materials and equipments were used in this study are commonly used for the fabrication of complete denture prosthesis in dentistry like autopolymerizing acrylic resin (DPI-RR cold cure, Denture base polymer resin), Nickel titanium (Ni-Ti) spring, medicated silicone rubber disc, digital spring weighing machine (guage), micromotor, straight handpiece, porcelain jar, wax knife, bard Parker knife, straight bur, alpine stone and sand paper. Result: The mean of retentive force in control group (without suction device) is 2.3 kg and the mean of retentive force with suction device cases is 2.7 kg. The mean were compared by using two tailed paired t test. The results showed that retention in the maxillary complete denture is significantly improved with the use of custom made suction device with a p value of 0.039. Conclusion: Within the limitation of this study it can be concluded that the custom made suction device improved the retention of the maxillary complete denture. Custom made fabrication of suction device was very cost effective and methodology of this study was very much comfortable for the patient.
