Material and methods: Eight completely edentulous patients were enrolled in this study to receive maxillary and mandibular complete denture (CD) sets made by conventional method, they worn these CD for three months constituting the first group (Group I) followed by two weeks as 1st wash out period. Then within the following three months, the patients received 3dimensional (3D) printed computer aided design computer aided manufacturing CAD/CAM CD sets made by indirect digital technique using extra- oral scan to capture patient clinical data to be analogical-digital technique constituting the second group (Group II), the patients left out their dentures for another two weeks for a 2nd washout period that was followed by another three months during which the patients worn 3D printed CAD/CAM CD sets made digitally by direct intra-oral scanning impression (IOSI) in combination with 3D face scan to constitute the third group (Group III). The retention force was measured as well as the patient satisfaction level was evaluated for every group two times, one and three-month post-insertion of CD. Results: The results of this study showed that there was significant differences between CD sets of Group II and that of Group III when compared to conventional CD sets .
