PRIMARY Changes in Soft Tissues Around Implant	243.89	—
SECONDARY Discrepancy (Trueness) Between STL Files in Teeth Adjacent to Implant	51.08	—

Summary

Six patients with a single unit implant in the anterior maxilla (from premolar to premolar), after at least 3 months with provisional implant supported restoration will be submitted to definitive implant impressions. Informed consents and local ethical committee clearance will be obtained. Patients will be submitted to a silicon impression with a customized impression coping from which a conventional cast will be obtained and scanned with D2000 (3Shape) and to an intraoral scan with Trios (3Shape). Standard Tessellation Language (STL) files will be obtained from both procedures and imported to reverse engineering software Geomagic Control X (3D Systems) and the distance between both scans will be calculated in a colored 3D map. From this map, two outcomes will be analyzed: the changes in soft tissues around implants with the two techniques (primary outcome) and the discrepancy between both scans in the teeth adjacent to the implants (secondary outcome).

Eligibility Criteria

Patients with single implant with adjacent teeth in the anterior esthetic area (Pre-Molar to Pre-Molar) of the upper arch with provisional implant crown use and indication for rehabilitation for definitive implant supported crown.

Exclusion Criteria

Patients without soft tissue contouring or without provisional implant supported use
