The effect of ceramic bonder on shear bond strength at the metal-ceramic interface in casted and direct metal laser sintering cobalt-chromium alloy - An in vitro study.

Aim:: (1) The aim of this study was to evaluate the effect of a ceramic bonder at the metal ceramic interface in sintered and casted cobalt–chromium (Co–Cr) alloy. (2) To compare the shear bond strength between the different manufacturing techniques: Casting and direct metal laser sintering (DMLS).

Setting And Design:: comparative study.

Comparative evaluation of enamel wear against monolithic zirconia and layered zirconia after polishing and glazing: An study.

Aim: The aim of this study was to compare the wear behavior of human tooth enamel opposing monolithic zirconia and layered zirconia after glazing and polishing by a two-body wear mechanism using a wear simulator.

Settings And Design: This In-vitro study was done in Department of Prosthodontics, Sri Sai College of Dental Research, Vikarabad.

Materials And Methods: Zirconia specimens were divided into four groups (n = 15), Group monolithic glazed zirconia (MG), Group monolithic polished zirconia (MP), Group zirconia layered with E.

Effectiveness of denture cleansers on flexible denture base resins in the removal of stains colored by food colorant solution: An study.

Aim: The aim of the study was to compare the efficiency of three denture cleansers (Valclean, Polident and Clinsodent) in removal of turmeric stains from flexible denture base resins.

Settings And Design: In vitro - comparative study.

Materials And Methods: A total of 45 specimens of flexible denture base resins were fabricated and subjected to baseline colour measurements using spectrophotometer.

Evaluation of flexural strength of Zirconia using three different connector designs: An study.

Aim: The aim of this study is to evaluate the flexural strength of zirconia using three different connector designs under vertical and oblique loads.

Setting And Design: Invitro - analytical study.

Materials And Methods: For simulating zirconia fixed partial prosthesis, a specimen with three octagonal cylinders connected with each other was designed.

A cephalometric analysis of Class II dentate subjects to establish a formula to determine the occlusal plane in Class II edentate subjects: A neo adjunct.

Purpose: Occlusal plane (OP) differs considerably in participants with skeletal Class I and Class II participants. In this study, cephalometrics has been used to help in the determination of orientation of the OP utilizing the nonresorbable bony anatomic landmarks in skeletal Class II participants and an attempt has been made to predict and examine the OP in individuals with skeletal class II jaw relationship.

Materials And Methods: One hundred dentulous participants with skeletal Class II malocclusion who came to the hospital for correcting their jaw relationship participated in the study.

An Study to Evaluate the Effect of Eugenol-free and Eugenol-containing Temporary Cements on the Bond Strength of Resin Cement and Considering Time as a Factor.

Aims And Objectives: The aim of this study was to assess the outcome of eugenol-free and eugenol-containing cements on the bond strength of resin cement.

Materials And Methods: Dentin was exposed in five groups of extracted teeth (20 specimens each). In Group 1, specimens were not given temporary cementation.

Versatility of PEEK as a fixed partial denture framework.

Materials used for fixed partial denture (FPD) frameworks have had properties of excellent strength, durability, and biocompatibility. Some of the materials which have been used till date include alloys, ceramics, and high-performance polymers such as zirconia, Ni-Cr, lithium disilicate, and so on. All these, though excellent, have their advantages and disadvantages.

Evaluating the fracture toughness and flexural strength of pressable dental ceramics: an in vitro study.

The study was undertaken to evaluate the biaxial flexural strength, biaxial flexural strength after etching with 9 % HF acid and fracture toughness of three commonly used pressable all ceramic core materials. Ninety glass ceramic specimens were fabricated from three commercially available leucite based core ceramic material (1) Esthetic Empress, (2) Cergo, and (3) Performance Plus. Thirty discs of each material were divided into three groups of 10 discs each.

Evaluation of Bone Density Around the Implants Placed Using Drilling Technique and Bone Expansion Technique: An In vivo Study.

Bone density is a key parameter in determining the surgical procedure of implant placement and for the predictability of successful implant treatment. Several clinical studies have shown lower survival rates of implants in maxilla which was attributed to poor bone quality. The present study compared the variations in the pre-operative and post-operative bone density values in Hounsfield units using CT between drilling technique and bone expansion technique at 0.

Rehabilitation of maxillary arch with attachment-retained mesh-reinforced single complete denture.

Fabrication of conventional complete dentures was one of the most commonly advised treatment options to mange edentulous patients since many years. One of the commonly encountered challenging tasks in prosthodontics is a clinical situation in which patients have maxillary completely edentulous arches opposing mandibular natural dentition. This situation can be effectively managed by retaining some of the natural teeth as overdenture abutments.

Combination of 2 three point articulators for preclinical work demonstration of teeth arrangement and anatomical landmarks.

The combination of 2 three point articulators was done to visualize and appreciate the various teeth setting principles and anatomical landmarks both in occlusion and out of occlusion. In other words this technique would give a simultaneous image of the various teeth arrangement principles at a glance. The various teeth arrangement principles highlighted in this article would be the following: individual tooth arrangement principles of anterior and posterior teeth, arch form, midline, incisive papilla, retromolar pad, overjet and overbite.
