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.
Eligibility Criteria
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).
