Brief summary

This clinical study will aim to compare and evaluate zygomatic implant stability, occlusal contact, and bone level changes around dental implants

Detailed description

The aim of this study will be to compare and evaluate zygomatic implant stability, occlusal contact, and bone level changes around dental implants and that of the atrophied maxilla rehabilitated with immediate loaded hyprid prosthesis supported by 4 zygomatic implants.

Interventions

DEVICEImplant supported hybrid maxillary prosthesis

All patients will receive immediately loaded hybrid prosthesis supported by 4 zygomatic implants.

Primary purpose

TREATMENT

Masking

NONE

Intervention model description

All patients will receive conventional maxillary and mandibular complete dentures The implant size will be selected for each area according to the available bone length and width as measured by CBCT radiograph. All implants will be surgically installed guided by steriolethognathic stents \- Multi-unit abutments will be connected to implants and will be immedietly loaded by fixed full arch screw retained provisional acrylic restoration. Final prosthesis will be delivered 6-8 months later
