Stereolithographic Technique for Dentures

Corina Marilena Cristache35 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

Evaluation of changes in Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT)

OHIP-EDENT-RO, validated for Romanian language questionnaire will be administrated at denture insertion and at 6, 12, 18 month follow-up

Time frame: up to 18 months

Secondary Outcomes

Evaluation of changes in masticatory performances assessed with Visual Analogue Scale (VAS)

At 6, 12 and 18 months clinical follow-up masticatory performance will be evaluated using VAS with units from 0 to 10 where 0 is "totally satisfied" and 10 is "not at all satisfied".

Time frame: up to 18 months

Evaluation of changes in denture retention with VAS

At 6, 12 and 18 months denture retention will be evaluated using VAS with units from 0 to 10 where 0 is "strong retention" ("totally satisfied") and 10 is "poor retention"("not at all satisfied").

Time frame: up to 18 months

Evaluation of denture changes in aesthetic aspect with VAS

At 6, 12 and 18 months denture aesthetic will be evaluated using VAS with units from 0 to 10 where 0 is "totally satisfied" and 10 is "not at all satisfied".

Time frame: up to 18 months
