Rehabilitation of an Atrophied Upper Maxillary Arch With an Implant-Supported Hybrid Prosthesis.

In a completely edentulous situation, providing a fixed hybrid prosthesis with the support of dental implants could be one of the viable treatment options. Such type of hybrid prosthesis is fabricated by applying the heat-cured polymerized resin over the metal framework and screwing the complete assembly into the implants. The objective of this case report is to illustrate the rehabilitation of the form, function, and esthetics of an atrophied upper maxillary arch by utilizing an implant-supported hybrid prosthesis.

Comparative Evaluation of Compressive and Diametral Tensile Strength in Die Stone Reinforced With Different Types of Nanoparticles: An In Vitro Study.

Aim: To investigate the effect of different types of nanoparticles on the compressive strength (CS) and diametral tensile strength (DTS) of type IV dental stones.

Materials And Methods: A total of 100 specimens were made from the mould for all five groups. Four commercially available nanoparticles (aluminium oxide (AlO), silicon dioxide (SiO), zinc oxide (ZnO), and zirconium oxide (ZrO)) were used in this study in a concentration of 10%.

A Comparative Evaluation of Flexural and Impact Strength of Polymethyl Methacrylate (PMMA) Reinforced With Graphene and Multi-Walled Carbon Nanotubes: An In Vitro Study.

Background and objective Low flexural strength (FS) and impact strength (IS) are major drawbacks in removable prostheses made from polymethyl methacrylate (PMMA). Attempts to enhance the strength and longevity of these prostheses have been of keen interest among researchers. Nanofillers are new and advanced reinforcements that can chemically modify PMMA.

Comparative Analysis of Three Different Impression Techniques for Impression Defects and Dimensional Accuracy Using a Digital Intraoral Scanner for Fixed Partial Dentures: An In Vivo Study.

Aim: To evaluate the impression defects and compare the dimensional accuracy of three different impression techniques (single-step, two-step without spacer, two-step with spacer) for fixed partial dentures using a digital intraoral scanner in the anterior maxillary region.

Materials And Methods: Thirty subjects, above the age of 18 years with maxillary central/lateral incisor requiring fixed prostheses were selected according to the inclusion and exclusion criteria. The impressions were rated and evaluated using Heine C2.

Effect of head posture on tooth contacts in dentate and complete denture wearers using computerized occlusal analysis system.

Purpose: The purpose of the study was to assess and compare the occlusal contacts in dentate and edentulous patients wearing complete denture with varying head posture.

Materials And Methods: sampling of 30 subjects (15 dentate and 15 edentulous) based on inclusion and exclusion criteria was done. Subjects were divided into two groups: dentate and edentulous.
