Fifty six patients were randomly enrolled in the study. Participants were randomly stratified into two control groups and two test groups, from which conventional pick up and digital impressions were made respectively. Patients of group 1 (CIG Axial) and 3 (DIG Axial) received 4 axial implants whereas, group 2 patients (CIG Tilted), and group 4 (DIG Tilted) received two anterior axial implants and two distal tilted implants. All participants received hybrid dentures. Bone loss, implant loss, maintenance of prosthesis were evaluated at 6m,12m, and 24 months follow up period.
