Study Overview
Brief Summary
A triple function scan Body were done on healed dental implant, thus simplifying the workflow for full arch cases and reducing the number of visits to only 3 visits. In this technique, scan bodies were utilized for implant position scanning, facial scan alignment and as stoppers for jaw relation capturing as scan bodies were used as stoppers for jaw relation registration.
Detailed Description
The present article describes a novel technique for merging a patient's facial scan with implant scan body and in the same time utilizing the same scan body for recording the jaw relation in only one visit. As a result, a facially driven full-arch implant-supported interim prosthesis can be fabricated first followed by the final restoration in a simplified approach. The aim of this study is to determine whether there is a difference between virtual design and reality using scan body technique (triple function scan body which reflects the accuracy of the scanning protocol. The null hypothesis established that there was consistency between the virtual design and prosthesis in patient's mouth. The scan body was placed in the edentulous arch in the jaw scan step so that bite registration would be easier for the intraoral scanner (IOS) in order to be able to capture both the teeth of the antagonist and part of the scan body in the edentulous jaw simultaneously.

Arms & Interventions
Triple Function Scan Body
Full arch implants were placed, a triple function scan Body and thus simplifying the workflow for full arch cases and reducing the number of visits to only 3 visits. Scan bodies were utilized for implant position scanning, facial scan alignment and as stoppers for jaw relation capturing as scan bodies were used as stoppers for jaw relation registration.
Intervention: Triple function scan body (Procedure)
Outcomes
Primary Outcomes
percentage of consistency in simultaneous contacts in maximal intercuspal position
Time Frame: 2 months following the final prosthesis
At 2 months follow up after final prostheses delivery, a frontal photo was taken and an intra oral scan was made for each patient in order to assess the degree of consistency between initial virtual design and reality using Exocad Software, The intra oral Scan of the full arch restoration is inserted into Exocad Software and the interocclusal contacts for all teeth were detected, classifying them in a dichotomy variable (yes/no) contact or not per tooth.
Secondary Outcomes
No secondary outcomes reported
