INFLUENCE OF ABUTMENT MATERIAL, CEMENT THICKNESS, AND CROWN TYPE ON THE FINAL COLOR OF IMPLANT-SUPPORTED RESTORATIONS.

Purpose: To evaluate the influence of abutment material, cement thickness, and crown type on the esthetics of implant supported restorations.

Material And Methods: In total, 60 specimens were prepared to represent six abutment groups: Group PA = pink-anodized Ti; Group GA = gold-anodized Ti; Group T = nonanodized Ti; Group H = hybrid (Ti + zirconia); Group P = PEEK (Ti + PEEK); and Group C = composite resin (control). Crown specimens (n = 120) were obtained from Vita Enamic (VE) and Vita Suprinity (VS).

Shear bond strengths of aged and non-aged CAD/CAM materials after different surface treatments.

Purpose: To assess shear bond strengths (SBS) of resin composites on aged and non-aged prosthetic materials with various surface treatments.

Materials And Methods: Cerasmart (CE), Vita Enamic (VE), Vita Mark II (VM), and IPS e.max CAD (EC) blocks were sliced, and rectangular-shaped specimens (14 × 12 × 1.

Evaluating Ceramic Repair Materials in Terms of Bond Strength and Color Stability.

Purpose: To evaluate the shear bond strength (SBS) and color stability (ΔE) of four ceramic veneers (VITA VM 9; VITA VM 13; VITA VMK 95; and IPS e.max Ceram) following repair with three different self-adhesive composite resins (Fusio Liquid Dentin; Constic; and Vertise Flow) and BISCO Intraoral Repair Kit + Filtek Supreme (BC + FS).

Materials And Methods: A total of 96 specimens were prepared per ceramic material, and each ceramic group was divided into subgroups according to testing method (32 specimens for color stability analysis and 64 specimens for SBS testing).

Could Microwave Glazing Be Considered as an Alternative to Conventional Surface Finishing Methods of Ceramic Materials in Terms of Color Stability?

Purpose: To examine microwave heating for the purpose of ceramic glazing as an alternative to conventional methods in terms of color stability.

Materials And Methods: Thirty disk-shaped specimens (11 × 2 mm) of VITA VM 9, VITA VM 13, VITA VMK 95, and IPS e.max Ceram veneers were prepared (n = 30 each).

A technique to facilitate the fabrication of provisional restorations for ITI solid abutments.

The aim of this technique report was to present a procedure for the fabrication of provisional restorations for ITI solid abutments using impression caps in the laboratory with a number of advantages over intraoral techniques. There may be no need for cementation, and elimination of cementation may assist tissue healing.

Alternative treatment procedure in the case of fractured abutment of adhesive bridge: a clinical report.

Unlabelled: In this case report, an alternative approach was presented for treatment of coronal fracture including pulp of maxillary central incisor, one of the abutments of an adhesive bridge, by using fiber post and tooth's own fractured component. The patient was referred to our clinic with the complaint of pain from the upper right central incisor and mobility of the adhesive bridge in maxillary anterior segment. It was realized that, the upper right central incisor, one of the abutments of the adhesive bridge, had been fractured at middle thirds of the crown including the pulp chamber.
