简要总结
Patients will be selected from the outpatient clinic of Removable Prosthodontic Department. Faculty of Dental Medicine for Girls, Al-Azhar University..
Each patient will be assessed for eligibility and Informed consent will be obtained from patient after explanation of the treatment protocols and expected outcomes or alternative management.
详细描述
All 10 patients will receive upper complete dentures and lower complete overdentures. The upper complete denture will be mucosa supported and the lower complete denture will be supported and retained for all patients by two dental implants in the inter-foraminal region. Patients will be divided into two groups, one group will be loaded by Novaloc attachment. While the other group will be loaded by Equator attachment. Implants will be functionally loaded after three months of insertion.
