| Objectives: This research was carried out to evaluate the bite force distribution of the maxillary complete dentures processed by injection molded (IM) and compression molded(CM) techniques opposed by implant retained over denture(IOD) using T-scan. Materials and Methods: Ten completely edentulous patients were rehabilitated by mandibular (IOD) and maxillary complete denture. Each patient received two maxillary dentures, one was formed of thermoplastic acrylic resin processed by (IM) technique and the other was formed of conventional acrylic resin processed by (CM) technique. The bite force distribution on the two maxillary dentures was evaluated by T-scan one week and three months after denture insertion. Results: In this study, at the end of the follow up period there was statistically significant difference in the bite force distribution between the (IM) &(CM) complete dentures. After one week of denture insertion, the means of difference of bite force distribution between the right and left posterior edentulous areas of (IM) &(CM) complete dentures were (7.700±3.860) and (15.80 ±4.984) consequently. While the means of bite force distribution for anterior edentulous areas of (IM) &(CM) complete dentures were (10.80 ±2.658) and (17.60 ±3.239) respectively. After three months, the means of difference of bite force distribution between the right and left posterior edentulous areas of (IM) &(CM) complete dentures were (9.400±4.695) and (18.40 ±7.106) consequently, and the means of bite force distribution in the anterior region were (16.40 ±2.591) and (23.80 ±3.824) in (IM) &(CM) complete dentures respectively. Conclusion: Within the limitation of this study, it could be concluded that IM complete dentures showed even bite force distribution along the posterior area of both sides of the edentulous arch and less bite force on the anterior edentulous area compared by CM complete denture. Both dentures showed increased bite force distribution by time on the anterior edentulous area. | ||||
