Microtensile bond strengths of adhesively bonded polymer-based CAD/CAM materials to dentin.

This in vitro study aimed to evaluate the effect of two different polymer-based CAD/CAM materials; resin-nano ceramic (Lava Ultimate [LVU]) and composite (CERASMART [CS]), their different surface pre-treatments, and use of different resin cements on the µTBS of adhesively bonded CAD/CAM onlays to dentin. CAD/CAM materials were cut into slabs and divided into five groups according to the surface pre-treatments applied: Silane Primer, OptiBond XTR adhesive, Silane Primer+OptiBond XTR adhesive, Single Bond Universal (SBU), and RelyX Ceramic Primer+SBU. The LVU and CS specimens were bonded to the mid-coronal dentin of 50 non-carious human molars using NX3 resin cement with OptiBond XTR or RelyX Ultimate with SBU.

The translucency effect of different colored resin cements used with zirconia core and titanium abutments.

Purpose: The purpose of this study was to evaluate the effect of the different color of resin cements and zirconia cores on the translucency parameter (TP) of the restoration that simulates the implant-supported fixed prosthesis using titanium base on the bottom.

Materials And Methods: Zirconia core plates (Zr-Zahn) were prepared in A2 shades (n = 11). Resin cement plates (3M ESPE) were prepared in A2, A1, translucent (TR) shades (n = 11).

The Effect of Luting Cement and Titanium Base on the Final Color of Zirconium Oxide Core Material.

Purpose: To evaluate the effects of different types of luting cements and different colors of zirconium cores on the final color of the restoration that simulates implant-supported fixed partial dentures (FPDs) by using a titanium base on the bottom.

Materials And Methods: One hundred and twenty zirconium oxide core plates (Zr-Zahn; 10 mm in width, 5 mm in length, 0.5 mm in height) were prepared in different shades (n = 20; noncolored, A2, A3, B1, C2, D2).

Comparison of the marginal fit of different coping materials and designs produced by computer aided manufacturing systems.

In this study, marginal adaptations of different copings fabricated with CAD/CAM or MAD/CAM were analysed. Celay and Zirkonzahn groups were fabricated by MAD/CAM, LAVA and DC-Zircon groups were fabricated by CAD/CAM. Casting metal copings were used as the control group.

Effect of Er:YAG laser irradiations on shear bond strength of three self-adhesive resin cements to dentin.

Objective: The purpose of this study was to evaluate the influence of Er:YAG laser irradiation on shear-bond strength of self-adhesive resin cements to dentin.

Background Data: Different laser-irradiation settings are used for dentin-surface pretreatment, which may affect the bond strength of resins.

Methods: Fourty-five extracted third molars were selected, sectioned in a mesiodistal direction, and 90 tooth slabs were obtained.

Shear bond strength of luting agents to fixed prosthodontic restorative core materials.

Background: Bonding properties of luting cements are important for retention of restorative core materials. The aim of this study was to compare the bonding performance of a resin-modified glass ionomer cement and a self-adhesive resin cement to various fixed prosthodontic core materials.

Methods: Cylindrical specimens with a thickness of 2 mm and a diameter of 5 mm were fabricated from Au-Pd-Ag, Co-Cr, Ni-Cr-Mo, Ni-Cr-Fe alloys, titanium, zirconia and Empress II (n = 20).

Evaluating factors that affect the shade-matching ability of dentists, dental staff members and laypeople.

Background: The authors conducted a study to evaluate the influence of dentists' and nondentists' experience, age, sex, eye color and use of eyeglasses or contact lenses on tooth shade-matching ability.

Methods: The authors included 120 participants in this study conducted in Istanbul (periodontists, oral and maxillofacial surgeons, orthodontists, endodontists, pediatric dentists, prosthodontists, restorative dentists, general dentists in private practice, dental technicians, dental assistants, dental assistant students and laypeople). The authors assigned participants to one of three groups: group 1 was composed of prosthodontists, restorative dentists and dental technicians; group 2 consisted of other dental specialists and general dentists; and group 3 included dental assistants, dental assistant students and laypeople.

Interdisciplinary management of a patient with skeletal anteroposterior discrepancy, impacted canine, and missing teeth.

For patients with complex dentofacial problems, orthodontic treatment is often not enough to obtain optimal esthetic and functional results. This case report demonstrates the treatment of a patient with skeletal anteroposterior discrepancy through an interdisciplinary approach and emphasizes the importance of collaboration with other dental disciplines to achieve the desired esthetic results.

An alternative treatment approach to gingival recession: gingiva-colored partial porcelain veneers: a clinical report.

This clinical report describes the treatment of excessive gingival recession involving maxillary right and left central incisors in a 30-year-old woman. The loss of the gingival soft tissue caused an increase in crown length. Gingiva-colored partial porcelain laminate veneers were applied to imitate the lost gingiva and to provide a natural anatomical tooth length.

Elongated mandibular coronoid process as a cause of mandibular hypomobility.

There are multiple factors in cases of mandibular hypomobility. One of these factors is elongated coronoid process. Two cases are presented to illustrate elongated coronoid process leading to mandibular hypomobility to help prevent misdiagnosis by clinicians.
