| Abstract Aim: This study aimed to evaluate the retention of digital mandibular complete dentures constructed from two different impression techniques for flat resorbed mandibular ridges. Subjects and Methods: sixteen completely edentulous patients with resorbed mandibular arch were selected. The patients were divided into two equal groups, group I (intervention group), in which the mandibular definitive impression was taken using all green impression technique, and group II (control group) where the definitive impression was taken using conventional impression technique. For both groups the master casts and the recorded jaw relation were laboratory scanned and the designed dentures were 3D printed. The retention of the mandibular complete denture was assessed at baseline (one week following denture insertion) and after 6 months using a digital force gauge. Statistics were done using Independent t test to compare retention in both groups. Significant difference was obtained when p value was set at < 0.05. Result: It was found that at baseline there was statistically insignificant difference between both groups. At six months, there were also insignificant difference between them, yet greater values regarding the all green technique was observed. Conclusion: Although there was insignificant difference between both impression techniques, printed complete dentures produced by final impression using all green technique could be beneficial for resorbed mandibular ridges regarding retention and ease of manipulation. | ||||
