Brief summary

This study will aim to evaluate the effect of two different implant positions, lateral incisors, and canine areas, on anterior and posterior ridge resorption and bone remodeling after different periods of denture insertion.

Detailed description

Twelve patients will be recruited from a previous study (14), having two-implant mandibular overdentures. Patients recalled from the database set of the clinic of the Removable Prosthodontic Department, Faculty of Dentistry, Mansoura University. The patients will be grouped based on the position of the two implants. All patients will be informed about all prosthetic procedures that will be done. Also, they will sign the consent form of the ethical committee of the faculty of dentistry, at Mansoura University. 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 excluded from the study Patients will be divided into two groups Group A (6 patients): Patients having two mandibular implants in lateral incisor positions. Group B (6 patients): Patients having two mandibular implants in canine positions.
