What this trial measures
- Evaluation of the depth of the shape of the intaglio surface of full-arch and its association with increased marginal bone level.The measurements will be assessed during the unique visit of the patient in the study.
After the prosthesis is scanned, and evaluation of the 3D file of the prosthesis will occur. A virtual line will be traced between the Buccal to the Palatal/Lingual flange of the prosthesis. In the middle point of this line, a perpendicular line will be traced in direction of the fitting surface of the prosthesis, intaglio, and this distance will be measured in mm.
