Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this observational study is: producing complete dental prosthesis with the aid of CAD-CAM (Computer aided design \& manufacturing) - 3D printing (Stereolithography) technology - using as printable material Poli(methylmetacrylate) - PMMA - with Nano TiO2 nanoparticles composite completely characterized.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In order to improve complete dentures fabrications an experimental model for optimizing the composite material and the execution technique for the 3D printed dental prosthesis was developed.

* A new polymer - nano-TiO2 composite system for dentures printing was obtained by adding 0,4-1%TiO2 nanoparticle in the commercially available E-Dent 100 (EnvisionTEC, Germany).
* The new polymer was completely characterized and biocompatibility tests were perform.
* A stereolithography technique was set-up for CAD-CAM complete dentures manufacturing.
* 3D printed dental prosthesis will be inserted to a number of 35 complete edentulous patients from a target group;
* Clinical follow-up at 6, 12 and 18 months and quality assessment of the dentures will be recorded in a specific chart.
* A statistical evaluation of data recorded during the entire follow-up period will be performed.
