About this study

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.

    stability of each implant measured using Osstell® device

Secondary outcomes

  1. Radiographic outcome

    Time frame: 12 months

    measuring bone resorption using the long-cone standardized periapical radiography
