简要总结
the study aims to investigate the clinical influence of different implant locations; lateral incisor, canine, and first premolar areas; supporting 2-implant retained mandibular over-dentures with locator attachment on prosthesis retention and peri-implant health.
详细描述
the study aims to investigate the clinical influence of different implant locations; lateral incisor, canine, and first premolar areas; supporting 2-implant retained mandibular over-dentures with locator attachment on prosthesis retention and peri-implant health.
- Thirty-six edentulous patients will be recalled from the database set of the clinic of the removable prosthodontic department, Faculty of Dentistry, Mansoura University. Patients will be recruited from previous studies, having two-implant mandibular overdentures.
- All selected patients with the following criteria: mandibular two implants retained overdenture opposing complete edentulous maxillary arch, attended the previous follow-up recalls with previous CBCT examination. Patients who didn't attend previous follow-up recalls, didn't perform radiographic follow-up, or had para-functional habits will be excluded from the study.
- The patients will be grouped based on the implant position:
Group I (12 patients): patients having mandibular two implants in lateral incisor positions.
Group II (12 patients): patients having mandibular two implants in the canine positions.
Group III (12 patients): patients having mandibular two implants in the premolar positions.
