Brief summary

the study is concerned with assessing retrospectively the survival and complication rates of monolithic zirconia implant-supported fixed full arch dental restoration scanned using scan ladder scan body over a follow-up period of 1 year.

Interventions

DEVICEscan ladder

Prosthetic steps with a digital workflow by placing horizontal scan bodies "scan ladder" and using of intraoral scanner "Medit i900" will be done. The final restoration is designed and a monolithic zirconia full arch titanium free restoration was milled and delivered after ensuring passivity and occlusion.

Inclusion criteria

* \- Any completely edentulous patient (mandible) with an old satisfactory denture requiring an implant-supported restoration. * Patients aged from 40 to 70, able to sign an informed consent will be considered eligible for this trial. * Implant sites must allow the placement of four implants. * Non- heavy Smokers will be included (smoking up to 10 cigarettes/day) * In case of post-extractive sites, they must have been healed for at least 3-month before being treated in the study. * Patients with no systemic condition that may interfere with implant placement (e.g., Immunosuppressed or immunocompromised patients, patients under treatment of intravenous amino-bisphosphonates)

Exclusion criteria
