About this study

Official title: Clinical Comparison of Prefabricated Resin Composite Veneers and Direct Resin Composite Veneers Over 6-years

The aim of this study is to compare the clinical performance of composite veneers performed in two different ways, indirect and direct methods over a period of 6-year.

30 volunteer patients without systemic diseases and who applied to Ege University School of Dentistry for the esthetic restoration of their anterior diastema (gap) were selected according to inclusion and exclusion criteria. The closure of 102 diastema was randomly performed with prefabricated composite resin veneers (n=15; indirect method- Componeer, Coltène, Altstätten, Switzerland) or direct composite resin veneers (n=15; direct method- Essentia, GC, Japan). These restorations were clinically evaluated at baseline, 1-2-6-year by two experienced and blind examiners according to modified Ryge criteria (USPHS criteria). Color match, marginal discoloration, anatomic form, marginal adaptation, secondary caries, surface roughness, retention, and polishing retention were evaluated for that purpose. Statistical analysis was performed with McNemar and Chi-square tests (p<0.05).

Read the detailed description

The aim of this study is to compare the clinical performance of composite veneers performed in two different ways, indirect (Componeer) and direct methods (Essentia) over a period of 6-year.

The study protocol was approved by the Ethical Committee of Ege University, Izmir, Turkey (16-2.1/8; 01.04.2016). 30 patients without any systemic diseases (10 males, 20 females, mean age: 34) and with aesthetic complaints on their anterior teeth were treated with 102 restorations (48 Componeer and 54 Essentia).

In Group 1; 48 teeth (15 patients) were restored with Componeer prefabricated veneers (Coltène, Altstätten, Switzerland) in combination with Synergy D6 nanohybrid resin composite (Coltène) and One Coat Bond (Coltène) adhesive system. In Group 2; 54 teeth (15 patients) were restored with Essentia (GC, Japan) micro-hybrid resin composite in combination with G-Premio Bond (GC) adhesive system.

Periodontal treatments, fillings, and bleaching treatments were performed, if necessary, before any veneer treatment. For the pre-treatment records; 3 photographs (smile, anterior occlusion, and upper anterior teeth alone) were taken from each patient. Both groups used the "Button Try" technique for color selection. Componeer sizing guide was used for size selection in Group 1. Then teeth were cleaned with non-fluoride pumice (Cleanic; Kerr Dental, ABD) using a polishing brush. Isolation of the teeth and retraction of the lips were achieved with a rubber dam (OptraDam, Ivoclar Vivadent, Liechtenstein). Prefabricated veneers were prepared for the cementation process in Group 1. Then the labial surfaces were etched using 36% phosphoric acid for 30 s. The etched surfaces were rinsed for 30 s and dried. One Coat Bond (Coltene) adhesive system was applied on the labial surfaces of the teeth in accordance with user instructions in both groups. In Group 1; Synergy D6 nano hybrid resin composite was placed on the inner surfaces of the prefabricated veneers before being applied on appropriate teeth. Then the restorations were light-cured for 40 s from each surface (D-Light Pro, GC) and polished with a polishing paste (Prisma Gloss Extra Fine, Dentsply, NY, ABD) and a felt wheel.

In Group 2; Essentia (GC) micro-hybrid resin composite with dentin color was placed on the labial surfaces of the teeth and light-cured (D-Light Pro, GC). After that layer, Essentia enamel shades were placed over the labial surface of the tooth and light-cured for 20 s from each surface. The diamond bur contouring was performed and polishing discs (Super-Snap Rainbow Technique Kit, SHOFU) were used. For polishing purposes, a polishing paste (Prisma Gloss Extra Fine, Dentsply, NY, ABD) and a felt Wheel were used.

In group 1; gingival borders were adapted with contouring and polishing discs (Super-Snap Rainbow Technique Kit, SHOFU). Then proximal surfaces were polished using proximal sandpaper strips. Occlusion was checked for premature contacts. Two calibrated observers who were blinded to the objective of this study performed the evaluations. Color match, marginal adaptation, marginal discoloration, anatomic form, retention, secondary caries, and gloss retention were the properties evaluated for the restorations at baseline, 1-2-6-year using Modified Ryge Criteria (USPHS Criteria). Statistical analysis was performed with McNemar and Chi-square tests (p<0.05).

Study groupRoleWhat they receive
Componeer Prefabricated VeneersActive comparatorComponeer veneers (device 1) were randomly applied to patients. The teeth were evaluated in terms of color and size matching in order to select the correct veneers. Componeer sizing guide was used for size selection. Prefabricated veneers were adapted to the teeth' surfaces. Then, the inner surfaces of the prefabricated veneers were roughened to obtain better mechanical retention. Then the labial surfaces of the teeth were etched using 36% phosphoric acid. The etched surfaces were rinsed and dried. An adhesive system was applied to the teeth. Prefabricated veneers' inner surfaces were cleaned with alcohol, and One Coat dental adhesive was applied. Synergy D6 nanohybrid resin composite was placed on the inner surfaces of the veneers and transferred to the teeth. The restorations were light-cured for 40 s Gingival borders were adapted with contouring and polishing discs (intervention 1).
Receives: Procedure: Componeer prefabricated veneers
Essentia resin composite vennersActive comparatorDirect resin composite restorations were randomly applied to patients. Essentia resin composite (device 2) shade guide was used for color selection. After the preparation, the labial surfaces of the teeth were etched using 36% phosphoric acid. The etched surfaces were then rinsed and dried. An adhesive system G-Premio Bond was applied to the teeth. Then Essentia micro-hybrid resin composite with dentin shade was placed on labial surfaces of teeth and was light-cured. Then enamel shade was placed on the tooth. After that, the resin composite veneer was light-cured for 20 s from each surface. Proximal surfaces were polished using proximal sandpaper strips (intervention 2).
