Wear Measurement of Opposing Enamel to Milled Resin Matrix Ceramic Versus Bulk Fill Resin Composite After 2 Years

Intraoral Wear Measurement of Opposing Enamel to Indirect Milled Resin Matrix Ceramic Versus Direct Bulk Fill Resin Composite in Posterior Teeth After Using 2 Years: Randomized Clinical Trial

This clinical trial conducted to measure the amount of wear of opposing enamel to indirect milled resin matrix ceramic versus direct bulk fill resin composite intraorally using Digital Scanner after two years of using

Study Overview

• Status: Completed
• Conditions: Dental Wear
• Intervention / Treatment: Procedure: Resin matrix ceramic block

Detailed Description

Indirect milled resin matrix ceramic overlay versus direct bulk fill resin composite overlay was utilized in a clinical trial to compare the amount of enamel wear on endodontically treated molars using a Panda P2 digital scanner and Geomagic Control X 3D software. After one and two years, measurements of enamel wear were taken.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Resin matrix ceramic block; BRILLIANT Crios is the ideal choice for single-tooth restorations, both in the anterior and the posterior region. It is composed of dental glass (barium glass ˂ 1.0 μm), amorphous silica (Sio2 ˂ 20 nm), resin matrix (cross-linked methacrylates) and pigments (inorganic pigments such as ferrous oxide or titanium dioxide).	Procedure: Resin matrix ceramic block; Milled resin composite block for fabrication of permanent, indirect restorations using a CAD/CAM grinding process. shock absorbing affect due to the dentin- like modulus of elasticity makes BRILLIANT Crios will suited or indirect restoration.; Other Names: CAD/CAM Reinforced composite overlay
Active Comparator: Direct Restoration; 3M™ Filtek™ One Bulk Fill Restorative is a visible light activated, restorative composite optimized to create fast and easy restorations. The material can be placed and cured up to 5 mm deep, enabled by a stress relieving resin system and optimized optical properties. It is composed of fillers which are a combination of a non-agglomerated/non-aggregated 20 nm silica filler. 4 to 11 nm zirconia filler, zirconia/silica cluster filler and ytterbium trifluoride filler consisting of 100nm particles. The inorganic filler loading is about 76.5% by weight (58.5% by volume). It contains AFM (dynamic stress-relieving monomer), AUDMA, UDMA and 1, 12-dodecane-DMA. 3M™ Filtek™ Bulk Fill Posterior Restorative is applied to the tooth following use of a methacrylate-based dental adhesive	Procedure: Resin matrix ceramic block; Milled resin composite block for fabrication of permanent, indirect restorations using a CAD/CAM grinding process. shock absorbing affect due to the dentin- like modulus of elasticity makes BRILLIANT Crios will suited or indirect restoration.; Other Names: CAD/CAM Reinforced composite overlay
