Evaluation of Composite Veneers Fabricated by 3D Printing and Milling Technologies (Randomized Controlled Clinical Trial & In-Vitro Study)
The clinical study aimed to evaluate the clinical performance, color stability, and wear of indirect composite veneers produced using 3D printing and milling technologies.
Panoramica dello studio
Stato
Completato
Descrizione dettagliata
A total of fifty-six anterior indirect veneers will be fabricated using 3D printing and milling technologies.
The veneers will be divided into two groups according to the technique of fabrication.
Group I: 28 veneers will be done using 3D printing technology (VarseoSmile TriniQ, Bego), and group II: 28 veneers will be done using milling technology (Cerasmart 270, GC).
Veneer restorations will be fabricated checked, and cemented, then will be evaluated using the modified FDI criteria at baseline, three months, six months, and one year.
Moreover, color stability and surface wear of the restorations will be evaluated in each follow-up session.

Lasso di tempo |
|---|---|---|
|
The functional properties of the examined veneer restorations
Lasso di tempo: 1 year
|
All veneers were assessed clinically at 1 week (baseline) and subsequently at 3, 6, and 12 months, following the FDI evaluation criteria and scoring system, which indicates: Functional properties: (F1) Fracture of material and retention.
(F2) Marginal adaptation.
(F3) Proximal contact point.
(F4) Form and contour.
(F5) Occlusion and wear.
Each evaluated property was scored according to the FDI criteria using the following clinical scores: Score 1: Clinically excellent/very good (VG), Score 2: Clinically good (CG), score 3: Clinically satisfactory (CS), score 4: Clinically unsatisfactory (CU), score 5: Clinically poor (PO).

The biological properties of the examined veneer restorations
Lasso di tempo: 1 year
|
All Veneers were assessed clinically at 1 week (baseline) and subsequently at 3, 6, and 12 months, following the revised FDI evaluation criteria and scoring system, which indicates: Biological properties (B1) Caries at restoration margins.
(B2) Dental hard tissue defects at the restoration margin.
(B3) Postoperative hypersensitivity and pulpal status.
Each evaluated property was scored according to the FDI criteria using the following clinical scores: Score 1: Clinically excellent/very good (VG), Score 2: Clinically good (CG), Score 3: Clinically satisfactory (CS), Score 4: Clinically unsatisfactory (CU), Score 5: Clinically poor (PO).

The color stability of the examined veneers
Lasso di tempo: 1 year
|
All Veneers were assessed clinically at 1 week (baseline) and subsequently at 3, 6, 9, and 12 months using the vita easy shade spectrophotometer.
The CIEDE2000 formula will be used to measure the color change.

Wear resistance of the examined veneers
Lasso di tempo: 1 year
|
All Veneers were scanned clinically using an intra oral scanner at 1 week (baseline) and subsequently at 3, 6, and 12 months.
The different scans were compared to baseline scan to assess the volume loss and accordingly the wear resistant.
