Brief Summary

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

Conditions

Dental Wear

Keywords

Wear measurements, resin matrix ceramic, Bulk fill composite, Digital scanner.

Outcome Measures

Primary Outcomes (1)

• Amount of Enamel Wear

  amount of enamel wear measured through superimposition of STL files exported from intraoral scanner then using geomagic Control X 3D

  two years follow up

Study Arms (2)

Resin matrix ceramic block

EXPERIMENTAL

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

Direct Restoration

ACTIVE COMPARATOR

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

Interventions

Resin matrix ceramic block PROCEDURE

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.

Also known as: CAD/CAM Reinforced composite overlay

Direct Restoration; Resin matrix ceramic block
