Overview
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.

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).
Arms & Interventions
IOP will be performed using a specialized photogrammetry system. The photogrammetry data will be use
Intervention: Intraoral photogrammetry (IOP) (Device)
IOS will be performed using commercially available IOS device. The scan data will be used to design
Intervention: Intraoral scanner (IOS) (Device)
Outcomes
Primary Outcomes
Scan time
Time Frame: At week 1 during the clinical visit of scanning the arch and bite registration.
Secondary Outcomes
- Prosthetic complications(At 3, 6 months of delivery of final prosthesis.)
