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

Experimental

Intervention: Intraoral photogrammetry (IOP) (Device)

IOS will be performed using commercially available IOS device. The scan data will be used to design

Active Comparator

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.)
