In vivo disintegration of four different luting agents.

The purpose of this study was to evaluate the disintegration of luting agents. An intraoral sample holder was made having four holes of 1.4 mm diameter and 2 mm depth.

Fracture resistance of ceramic veneers with different preparation designs.

Purpose: The purpose of this study was to examine the fracture load of ceramic veneers with different preparation designs.

Materials And Methods: Seventy-five extracted, intact, human maxillary central incisors were prepared according to five preparation designs (P) (n: 15) as follows: (1) P2e: 2-mm incisal reduction, preparation entirely in enamel; (2) P4e: 4-mm incisal reduction, preparation entirely in enamel; (3) P2d: 2-mm incisal reduction, preparation entirely in dentin; (4) P4d: 4-mm incisal reduction, preparation entirely in dentin; and (6) Pc: Unrestored, intact teeth as control. All preparations had a butt joint incisal finish line, rounded internal line angles, and cervical finish lines 1 mm above the cementoenamel junction.

Erosion of luting cements exposed to acidic buffer solutions.

The aim of this study was to evaluate acidic erosion of 7 luting cements. Erosion was evaluated via immersion in 0.1 M aqueous sodium lactate/lactic acid buffer (pH = 2.

In vivo and in vitro evaluation of marginal fit of class II ceromer inlays.

The aim of this study was to evaluate the marginal adaptation of class II ceromer (Targis, Vivadent) indirect inlay restorations under both in vivo and in vitro conditions. Twenty Targis inlays were produced for class II inlay cavities (13 mandibular and seven maxillary teeth) in 20 patients. The in vivo adaptation of the inlay to the tooth cavity was evaluated by means of silicone replica technique.

The use of all-ceramic restorations to splint periodontally compromised teeth: a clinical report.

This clinical report describes the use of an all-ceramic system to restore periodontally compromised teeth. A metal-free post-and-core system and all-ceramic crowns were used to splint the teeth and fulfill the esthetic demands.
