A gold-nickel master alloy was prepared by arc melting in an inert atmosphere and from it, mechanical test specimens and dental prostheses were made by centrifugal casting. The cast alloy had a yield strength of about 7,400 kg/cm2, with an elongation of 12%. The alloy was clinically tested in the form of partial dentures and crown and bridge materials. For the 32-month period these prostheses have been in use, no tissue reaction, tarnish, or corrosion had been observed.

A case series on the basic concept and design of removable partial dentures: support and bracing considerations.
BMC Oral Health
January 2025
Department of Removable Prosthodontics, School of Dentistry, Aichi Gakuin University, 2-11 Suemori- dori, Chikusa-ku, Nagoya, Aichi, 464-8651, Japan.
Background: When designing removable partial dentures, maximizing the effectiveness of support and bracing is necessary to minimize denture movement. Therefore, it is essential to emphasize the importance of providing patients with appropriate, safe, and secure removable partial dentures and have clinicians rerecognize the concept and importance of support and bracing. This study aimed to present extension-base removable partial dentures through six specific clinical case series and describe the effect of support and bracing action on denture design, which is essential for denture movement minimization.

Conservative Dentistry Department, Faculty of Dentistry, Cairo University, Cairo, Egypt.
Background: In recent years, there have been suggestions for new restorative strategies that aim to effectively utilize modern adhesive technologies and protect the remaining intact tooth structure. This study was conducted to evaluate the clinical performance of fiber reinforced resin composites in restoring Class II MOD cavities over 18 months.
Methods: Forty-five participants with class II MOD cavities were randomly enrolled.
Similar patient-reported satisfaction and professional appraisal of implant-supported fixed dental prosthesis fabricated by different workflows.
Evid Based Dent
January 2025
Division of Periodontics, Centre for Dental Education and Research, All India Institute of Medical Sciences, New Delhi, India.
Design: A triple-armed, double-blind randomized controlled trial with cross-over design investigated patient-reported satisfaction and objective dental evaluation of a 3-unit, monolithic zirconium dioxide (ZrO2), implant-supported fixed dental prosthesis (iFDP) fabricated with 2 completely digital workflows and 1 mixed analog-digital workflow.
Case Selection: Participants enrolled required rehabilitation of 2 dental implants in posterior region of either of the arches with a 3-unit, ZrO2 iFDP. A total of 20 participants received the 3 types of ZrO2, iFDP fabricated by 3 different methods.
Can monolithic zirconia frameworks in implant-supported cross-arch prostheses deliver reliable long-term outcomes?
Evid Based Dent
January 2025
Eastman Dental Institute, London, UK.
Design: A retrospective cohort study assessing the mid-to-long-term outcomes and risk factors affecting the prosthetic success and survival of implant-supported cross-arch fixed dental prostheses (IFCDPs) with monolithic zirconia frameworks.
Cohort Selection: Forty-seven patients received a total of 51 cross-arch prostheses (27 maxillary and 24 mandibular prostheses), supported by 302 implants. Comprehensive clinical and radiographic records were available over a follow-up period ranging from 5 to 13 years.

This study aims to evaluate the potential enhancement in implant classification performance achieved by incorporating artificially generated images of commercially available products into a deep learning process of dental implant classification using panoramic X-ray images. To supplement an existing dataset of 7,946 in vivo dental implant images, a three-dimensional scanner was employed to create implant surface models. Subsequently, implant surface models were used to generate two-dimensional X-ray images, which were compiled along with original images to create a comprehensive dataset.
