New Treatment Approaches for Patients Who Have Extensively Resected Maxillae

BACKGROUND The purpose of the study was to assess bond strength of various modern resin cements based on CAD-CAM ceramic in multilayer technique. METHODS CAD-CAM blocks specimens, IPS e.max ZirCAD (core, n=60) and IPS e max CAD (veneer, n=60) were fabricated. All specimens were divided into 3 groups (n=20). By multilayer technique, zirconia core an...

Objectives: This study was conducted to compare the satisfaction and the quality of life in an elderly population using either mandibular conventional complete dentures or implant retained complete dentures. Materials and Method: A total of 120 patients were divided into two groups: group 1 conventional denture wearers; group 2 implant retained den...

Objective: The aim of this study was to evaluate the effect of different polishing systems on the colour stability of different laminate veneer blocks for chair-side CAD-CAM after ultraviolet (UV) ageing. Methods: About 240 sample (13×13×0.7) were prepared from four different CAD-CAM blocks IPS e.max CAD (IP), IPS Empress CAD (IE), Mark II (M) and...

In the current study, we evaluated the effects of heat treatment (by Er:YAG or furnace) and various surface treatments on the microtensile bond strength (μTBS) of silanized lithium disilicate ceramic. Seventy lithium disilicate (IPS e. max Press; Ivoclar Vivadent) and composite resin (Tetric N-Ceram; Ivoclar Vivadent) blocks were made and distribut...

Background Muscle-related temporomandibular disorders (TMD) may affect the masticatory function. Chewing function can be assessed objectively using bolus kneading tests, such as two-color chewing gum mixing ability test. Objective The aim was to compare the masticatory function with a two-color chewing gum test before and after treatment of the ma...

BACKGROUND The purpose of this in-vitro study was to compare the colour stability and bond strength of zirconia-based ceramic restorations after hydrothermal aging using conventional layering, heat-pressing, and multilayer veneering techniques. METHODS One hundred twenty specimens’ core (15 x 10 x 0.7) was fabricated from A2-shade zirconia CAD-CAM...

Objective: The purpose of this study was to investigate the effect of mouth rinses on the color and translucency of three computer-aided design and computer-aided manufacturing (CAD-CAM) restorative materials in laminate veneer and crown thicknesses. Methods: Specimens from two different 5Y-TZP zirconia (InCoris TZI (IT), and Zirkonzahn (ZH)) an...

During the development of technology and arising creative methods to make the human life easier, the necessity of accelerating treatments has become a necessity. Laser therapy is preferred by the patient and dentist with the advantages of less time taking, bleeding, swelling, scarring and pain relief. With the development of laser types their appli...

Background The aim of this study was to analyze the surface roughness of yttrium stabilized tetragonal polycrystalline zirconia (Y-TZP) ceramics after different laser treatments (CO2, ER: YAG). Methods 5x5x2 mm rectangular prisms of forty eight Y-TZP (Zirkonzahn) ceramic specimens were prepared. In order to standardize surfaces, 600-, 1200- grid s...

Introduction: This study was conducted to find out different polishing techniques' effects on different porcelain materials by using atomic force microscopy (AFM).

This study examined the antioxidant treatment on the shear bond strength of composite resin to enamel after bleaching with two different bleaching systems. Seventy flat enamel surfaces were prepared from freshly extracted human molars using a low speed diamond saw. Then the specimens were divided into seven random groups (n = 10) to apply different...

We investigated the effects of different Er:YAG laser treatments on the surface roughness of base metal alloys. A total of 36 specimens were prepared of two base metal alloys (Wiron 99, Bellabond plus). The surfaces of the specimens were standardized by gradual wet grinding with 320-, 600-, 800- and 1,000-grit silicon carbide paper for 10 s each on...

There are several surface treatment methods to improve the bond strength between dental materials. The purpose of this study was to examine the effect of different surface treatments on the tensile bond strength of single crowns on Implant Direct abutments cemented with resin cement. Materials and methods: In total, 28 Screw Plant implants and abut...

The purpose of this study was to investigate the effect of tooth supported (TSD) and tooth-tissue supported (TTSD) removable partial denture wearing on pulpal blood flow (PBF) of the abutment teeth by using Laser Doppler Flowmeter (LDF). Measurements were carried out on 60 teeth of 28 patients (28 teeth and 12 patients of TTSD group, 32 teeth and 1...

Prosthodontic rehabilitation can be accomplished with fixed, overdenture, complete, or implant-retained prostheses. Dental treatment overcomes the patient's functional, psychological, esthetic and phonation problems. Remaining healthy teeth may allow the dentist to fabricate a removable partial overdenture, fixed partial prosthesis or implant - sup...
