Brief summary
Objectives: evaluate the success rate, prosthetic maintenance , clinical and radiologic results of vertical implants with straight abutments versus inclined implants with angled abutments to retain locator maxillary overdentures. There were two groups : 1) The control group 2) The study group
Detailed description
the aim of the present investigation was to evaluate the success rate, prosthetic maintenance , clinical and radiologic results of vertical implants with straight abutments versus inclined implants with angled abutments to retain locator maxillary overdentures. Materials and Methods conducted on 12 patients (6 males and 6 females) aged 58 to 68 years with completely edentulous maxillary ridges opposing implant-retained mandibular overdentures. Patients admit to the prosthodontic department, Faculty of Dentistry, Mansoura University for oral rehabilitation by implant-supported maxillary prostheses. Patients were allocated into one of two treatment groups: 1) The control group ; included 6 patients (3 males and 3 females) who will receive 4 vertical implants with straight trans mucosal abutments retaining locator maxillary overdenture 2) The study group; include 6 patients (3 males and 3 females) who will receive 4 inclined implants with angled trans mucosal abutments for retaining locator maxillary overdenture. Randomization and allocation of patients into treatment groups was made by dental personnel who is blind to treatment groups.

Intervention model description
Randomized controlled clinical trial study conducted on 12 participants with completely edentulous maxillary ridges. Patients were allocated into one of two treatment groups: 1) The control group ; included 6 patients (3 males and 3 females) who will receive 4 vertical implants with straight trans mucosal abutments retaining locator maxillary overdenture 2) The study group; include 6 participants (3 males and 3 females) who will receive 4 inclined implants with angled trans mucosal abutments for retaining locator maxillary overdenture. A new maxillary conventional dentures will be constructed with a bilateral balanced occlusal concept for all patients. Maxillary dentures were duplicated into heat cure acrylic resin dentures to be used as a radiographic template. Four implants were inserted in the maxilla . For both groups, locator abutments were screwed to the abutments .Clinical and radiographic evaluations were done.
