Study Overview

Brief Summary

The goal of this clinical trial is to evaluate the clinical performance of Class II restorations of a thermoviscous nanohybrid materials , of a bulk-fill composite resin, and of conventional nanohyribrid bulk-fill composite resins .

Class II restorations will be performed in patients using three different restorative materials.And restorations will be evaluated using modified US Public Health Service criteria Resorations will be photograped and restorations will be evaluated for 6,12 months.

Detailed Description

The aim of this clinical study was to evaluate the clinical performance of Class II restorations of a thermoviscous nanohybrid materials , of a bulk-fill composite resin, and of conventional nanohyribrid bulk-fill composite resins.

Methods and Materials: Class II restorations will be performed in patients using three different restorative materials: VisCalor Thermoviscous Bulk-Fill (VCB; a thermoviscous nanohybrid bulk-fill composite resin) , Admira Fusion x-tra ( AFT: a conventional nanohybrid bulk-fill composite resin) and 3M Filtek One Bulk-Fill Restprative (FOB: a conventional bulk-fill nanocomposite ) Futura Bond U adhesive will be used for both conventional bulk-fill composite resin restorations and thermoviscous bulk-fill composite resin restorations.

Criteria for inclusion of patients in the study : Healthy individuals without any systemic disease, patients who is between 18 and 60 years old, patiens who brush their teeth 2 times a day,voluntary individuals who have agreed to participate in the study and signed the illuminated consent form, who have been given initial periodontal treatment.

Criteria for not inclusion of volunteers in research:Women who are pregnant or breastfeeding ,patienrs with advanced periodontial disease,patiens using a moving segmental prosthesis,patiens who have maloclusions,patiens who have bruxism,patients with known allergies to resin-based restorative materials and binding agents

The restorations will be evaluated using modified US Public Health Service criteria in terms of retention, color match, marginal discoloration, anatomic form, marginal adaptation, secondary caries, postoperative sensitivity, and surface texture. Resorations will be photograped and restorations will be evaluated for 6,12 months

Arms & Interventions

VisCalor Bulk

Active Comparator

Thermoviscous Bulkfill composite resin Warming of the material makes it flowable for the application and then sculptable immediately afterwards (thermoviscous technology) Optimal flowing to margins and undercut regions One universal and three aesthetic shades Cannula form

Intervention: VisCalor Bulk,VOCO,Germany (Device)

Admira Fusion x-tra

Active Comparator

Ormocer based bulkfill composite Purely ceramic-based, bulk fill restorative material Reliable curing of 4 mm layersby far the lowest polymerisation shrinkage (1.25 % by volume) and particularly low level of shrinkage stress, providing optimal marginal integrity.

inert, so excellent biocompatible and extremely resistant to discolouration Easy handling, simple high-lustre polishing procedure coupled with high surface hardness guarantee first-class long-term results Universal shade with chameleon effect

Intervention: Admira Fusion x-tra,VOCO,Germany (Device)

Filtek One Bulk

Active Comparator

Conventional bulkfill compositeFocused options powered by 3M technology help you complete posterior restorations in a single bulk placement.

5 shades avaible : A1, A2, A3, B1, and C2. Excellent adaptation and sculptability for fast, easy placement. One-step placement : Tackle deep cavities with up to 5 mm depth of cure

Intervention: Filtek One Bulk,3M,Germany (Device)
