Prosthesis Durability
Conditions
Brief summary
This study will compare the occlusal accuracy of different techniques for recording maxillomandibular relationships in a Complete digital workflow to construct full arch implant-supported screw-retained restoration.
Interventions
DEVICEImplant supported screw retained prosthesis
All patients will receive six maxillary and mandibular implants for full arch screw retained prosthesis

Intervention model description
digital impressions will be made for each patient,3 technique will be used to determine intermaxillary relation. Occlusal prematurties of final prosthesis will compared using occlusense device and all patients will be followed up for one year
