Objective: to illustrate the danger of using acrylic denture as removable partial denture in a developing country.
Method: post mortem examination was performed on a man who died after ingesting removable partial denture.
Results: A removable partial denture was seen seated in the mid portion of the oesophagus with its lateral wings deeply embedded in the wall of the oesophagus causing laceration and severe haemorrhage.
Conclusion: The radiolucent nature of acrylic denture may prevent early diagnosis and intervention when it is ingested or aspirated. There is need for proper education of patients wearing partial denture in especially the acrylic type.

Recent research has indicated that placing dental implants in patients diagnosed with bruxism has led to higher rates of implant failure. This study aimed to provide more accurate knowledge about the relationship between bruxism and implant loss in patients (number, age, gender) with different numbers of implants and prosthetic restorations, considering the follow-up time, compared to non-bruxers. A systematic search was conducted in PubMed and Cochrane Library using the keyword combination "dental implant", "bruxism", and "implant failure".

The present article describes a step-by-step maximally digitalized workflow protocol with computer-aided design and computer-aided manufacturing (CAD/CAM) in partial-arch edentulous patients rehabilitated with fixed dental prostheses and removable partial dentures (FDPs and RPDs). Facial digitalization, intraoral scans, and functional mandibular movement recordings were used to create a 4D virtual patient on commercially available CAD software. The fixed components including post-and-cores, both metal-ceramic with extra-coronal attachment and monolithic zirconia crowns, and the RPDs were manufactured by computer numerical controlled direct milling.

Introduction The utilization of Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) technology in the production of polyetheretherketone (PEEK) and acetal frameworks enhances the precision and stability of partial denture frameworks. This study evaluates the retentive forces of CAD/CAM-fabricated PEEK, acetal, and cobalt-chromium (Co-Cr) frameworks in removable partial dentures (RPDs). Methods Forty-five frameworks were fabricated (15 each of PEEK, acetal, and Co-Cr) and tested for retentive forces using a universal testing machine at a crosshead speed of 5 mm/min.

Background: Computer-assisted learning (CAL) has the potential to enhance learning outcomes and satisfaction. However, there are limited reports in the literature that describe or evaluate the implementation of this method to promote competency-based learning in removable partial denture (RPD) design. Therefore, this study aimed to: (1) compare the effectiveness of different learning methods using a 3D software-aided RPD design program, (2) evaluate the learning outcomes associated with these different methods following active learning, and (3) assess students' satisfaction.

Objectives: To assess the effect of occlusion and implant number/position on stress distribution in Kennedy Class II implant-assisted removable partial denture (IARPD).
Materials And Methods: IARPDs were designed in six models: with one implant (bone level with a platform of 4 mm and length of 10 mm) at the site of (I) canine, (II) between first and second premolars, (III) first molar, (IV) second molar, or two implants at the sites of (V) canine-first molar, and (VI) canine-second molar. A conventional RPD served as control.
