Brief Summary
On of the main fixed prosthetic options of completely edentulous patients is the screw-retained implant supported prosthesis which was constructed on transmucosal abutments with its encountered problems such as: hardness to make it passively seated with multiple screw fracture and loosening problems and multiple encountered veneer material fracture and so there effect on patient satisfaction with multiple maintenance recalls.so, the investigators want to try a new technique of fabrication which was proposed for reducing the problems of lack of passivity which is the intraoral luting cement technique on titanium bases with reduced screw number but, with luting cement problems as de-cementation and cement biological effects on soft tissues and bone and there effect on number of patient recall visits and maintenance and so there effect on patient satisfaction

Eligibility Criteria
You may qualify if:
- \- Completely edentulous patients
- Patients with completely edentulous ridges have an opposing natural dentition or implant supported overdenture
- Completely edentulous patients (with the above mentioned criteria) who have proper amount of attached gingiva (≥2 mm) or to be created
- Completely edentulous patients (with the above mentioned criteria) who have no history of bruxism
- Completely edentulous patients (with the above mentioned criteria) who were free or controlled diabetic assessed by measuring glycosylated haemoglobin (HbA1c). (lesser than or equal to 6.4 percent )
You may not qualify if:
- \- Patients having a medical condition that absolutely contraindicates implant placement.
- Patients with uncontrolled diabetes, assessed by measuring glycosylated haemoglobin (HbA1c). (greater than to 6.4 percent )
- Potentially uncooperative patients who are not willing to go through the proposed interventions. - Moderate-to-heavy daily smokers\* (who report consuming at least 11 cigarettes/day).
- Patients who are having complete lower denture
- Patients who have history of bruxism
