Brief summary

This study aims to evaluate the effect of intra-oral scanning and intra-oral photogrammetry on scan time and prosthetic complications in patients receiving full-arch titanium framework with zirconium overlay implant screw-retained prostheses. Participants will: Receive a full arch implant prosthesis and scan time will be recorded. Prosthetic complications (e.g., screw loosening, framework fracture, zirconia chipping) will be recorded at 3 and 6-month follow-up period post-delivery and we will manage complications at the time of prosthetic complication occurrence.

Interventions

DEVICEIntraoral photogrammetry (IOP)

IOP will be used in the study to take a digital impression for the implants. The scanner will be used to record the soft tissue anatomy and trans-mucosal abutments. 3D Scan bodies will be fitted on the trans-mucosal abutments that are screwed on the implants to capture their position and scanning will be done. A scan of the soft tissue and scan bodies will finally be conducted.

DEVICEIntraoral scanner (IOS)

Intra-oral scanner will be used in the study to take a digital impression for the implants. 3D printed generic Scan bodies with unified shape and length replacing the traditional transfer copings will be press fitted on the trans-mucosal abutments and pickup cylinders that are screwed on the implants to capture their position and intra-oral scanning will be done.

Inclusion criteria

* Patients requiring maxillary and/or mandibular full arch screw-retained implant-supported prosthesis. * Number of implants placed per arch ranging from 4-6 implants per arch. * Completely edentulous patients with sufficient inter-arch space to receive fixed prosthesis (Crown height space 9-15 mm per arch). * Adequate zone of keratinized mucosa (\> 2mm width). * Both genders. * Acceptable oral hygiene. * Cooperative patients. * Controlled systemic diseases (Diabetes, hypertension).

Exclusion criteria

* Completely edentulous patients with insufficient inter-arch space to receive fixed prosthesis (Crown height space lesser than 9mm per arch). * Completely edentulous patients with in-adequate zone of keratinized mucosa (\< 2mm). * Un cooperative patients. * Poor oral hygiene. * Uncontrolled systemic diseases (Diabetes, hypertension).
