Summary

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

Detailed 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.

Conditions

• Prosthesis Durability

Interventions

Type	Name	Description
OTHER	impression techniques for implant used for maxillary screw retained hybrid prosthesis	conventional splinted open tray impression technique was done for maxillary implants to fabricate screw retained hybrid prosthesis and digital intra oral impression was done for the same patients after screwing scan bodies to the implants intra orally. evaluation of accuracy and 3D deviation between the two techniques was done
