Accuracy of Conventional and Digital Impression Techniques Used for Maxillary Hybrid Prosthesis

Prosthesis Durability Clinical Trial

Official title:
Accuracy of Digital and Conventional Impression Techniques for Maxillary Full Arch Screw Retained Hybrid Prosthesis

Clinical Trial Summary

evaluation and comparison of the accuracy of conventional and digital impression for full arch screw retained prosthesis for edentulous maxilla.

Clinical Trial Description

Each patient received 6 implants in the maxillary ridge (widely distributed across the arch) in the following positions: central incisors, canines/first premolar teeth and first molar teeth aided by surgical stent. then each patient received 2 types of impression techniques Technique 1 :conventional impression conventional open tray impression technique with splinted transfers using vinylpolysiloxane and Technique2 : Digital impression taken using original scan bodies torqued to the implants .three dimensional accuracy of impression techniques was evaluated using linear measurements and 3D deviation between the two techniques was measured. ;
