Direct cuspal-coverage posterior resin composite restorations: A case report.
The clinical success of direct composite restorations is the result of the correct use and performance of adhesive systems, resin composites and light curing systems. Total-etch adhesive systems and microhybrid resin composites have seen continuous improvement; various clinical techniques have been introduced to address polymerization shrinkage. Manufacturers have introduced sophisticated light...
متن کاملClinical evaluation of direct cuspal coverage with posterior composite resin restorations.
BACKGROUND Composite resins have esthetic properties; they join the ability to preserve and reinforce sound tooth structure. Conservation is becoming popular for both small to medium defects and more compromised teeth. PURPOSE This study aimed to evaluate the clinical performance of Class II cuspal coverage direct composite restorations. MATERIALS AND METHODS Twenty patients, 18 years or ol...
متن کاملCuspal deflection and depth of cure in resin-based composite restorations filled by using bulk, incremental and transtooth-illumination techniques.
BACKGROUND Restoration techniques affect shrinkage stress and depth of cure. The authors tested cuspal deflection and depth of cure resulting from the use of different techniques (bulk, incremental, bulk/transtooth illumination) and two resin-based composites (deep curing and conventional). METHODS The authors restored extracted teeth with deep-curing X-tra fil (VOCO, Cuxhaven, Germany) (by u...
متن کاملEffect of light curing units on marginal adaptation and hardness of Class II composite resin restorations.
AIMS The aim of this study was to test the influence of different curing protocols on dentin marginal adaptation and the hardness of two composites. METHODS AND MATERIALS Three light-curing-units (LCUs): Quartz-Tungsten-Halogen (QTH: 541 mW/cm2), Argon-Ion-Laser (AL: 277 mW/cm2), and Plasma-Arc-Curing (PAC: 1818 mW/cm2) and two composites FiltekZ250 (F) and Tetric Ceram HB (TC) were tested. S...
متن کاملFactors affecting marginal integrity of class II bulk-fill composite resin restorations
Background. Bulk-fill composite resins are a new type of resin-based composite resins, claimed to have the capacity to be placed in thick layers, up to 4 mm. This study was carried out to evaluate factors affecting gap formation in Cl II cavities restored using the bulk-fill technique. Methods. A total of 60 third molars were used in this study. Two Cl II cavities were prepared in each tooth, o...
