Removable partial dentures (RPDs) are used to restore missing teeth and are traditionally fabricated using the lost-wax casting technique. The casting process is arduous, time-consuming, and requires a skilled technician. The development of intraoral scanning and 3D printing technology has made rapid prototyping of the RPD more achievable. This article reports a completed case of direct fabrication of a maxillary RPD metal framework (Kennedy Class I) using intraoral scanning and 3D printing techniques. Acceptable fit and satisfactory clinical outcome were demonstrated...

Selective laser melting (SLM) technology was recently introduced to fabricate dental prostheses. However, the fatigue strength of clasps in removable partial dentures prepared by SLM still requires improvement. In this study, we attempted to improve the fatigue strength of clasps by adding support structures for overhanging parts, which can generally be manufactured at an angle to be self-supporting. The results show that the fatigue strength of the supported specimens was more than twice that of unsupported specimens...

Moebius/Mӧbius Syndrome (MS) is an extremely rare congenital disorder characterized by uni- or bilateral palsy of the abducens (VI) and the facial (VII) nerves, causing facial paralysis. Dysfunction of cranial nerves III through XII is common, most often the glossopharyngeal (IX) and hypoglossus (XII). Afflicted individuals seeking prosthodontic care, particularly removable prosthetics, present multiple challenges related to inherent facial and tongue muscle weakness and microstomia. Other extraoral anomalies may include congenital multiple arthrogryposis and malformations of the upper and lower limbs...

Longevity of implant-supported fixed partial dentures (ISFPDs) may be associated with multiple clinical complications, irrespective of whether retention is achieved via screws or cement. While use of screws ensures ease of prosthesis retrievability and elimination of the inherently risky cementation process, more mechanical strains are induced in this design. A combined screw-retrievable and cement-retained ISFPD is designed to achieve the best passive fit and strain reduction while allowing complete excess cement removal and maintaining ease of retrievability...

PURPOSE: Restoration of partial edentulous mouth may be done using a variety of treatment options. Removable partial denture (RPD) is commonly used because of its availability. RPDs from flexible resins unlike those from acrylic engage hard and soft tissue undercuts and feel more comfortable in the mouth. The aim of the study was to compare satisfaction with dentures made from these two types of materials. MATERIALS AND METHODS: It was a quasi-experimental study among thirty patients at the Prosthetics Clinic, University College Hospital, Ibadan...

The restoration of normal function and esthetic appearance with a dental prosthesis is a major challenge in the rehabilitation of patients who have lost their teeth and surrounding bone because of surgery for oral cyst or tumor. Rehabilitation with fixed or removable prosthesis is even more challenging when the edentulous span is long and the ridge is defective. Anatomic deformities and unfavorable biomechanics encountered in the region of resection add to the misery. In such situation, a fixed-removable prosthesis allows favorable biomechanical stress distribution along with restoration of esthetics, phonetics, comfort, hygiene, and better postoperative care and maintenance...

A removable veneer-type palatal augmentation prosthesis (PAP) was attached to a complete denture to reduce weight and maintain good hygiene. As a result, the weight of the PAP was reduced from 27.1 g at the time of palatal augmentation, by using the tissue conditioner, to 16.6 g, with the definitive removable veneer-type prosthesis. This method can also be applied to removable partial dentures when the impression of the palatal augmentation is properly positioned on the definitive cast after the removal of the tissue conditioner...

The use of a single metal for all restorations would be necessary because it protects against metal corrosion caused by the contact of different metals. For this "one-metal rehabilitation" concept, non-alloyed commercially pure (CP) titanium should be used for all restorations. Titanium frameworks have been cast and used for the long term without catastrophic failure, whereas they have been fabricated recently using computer-aided design/computer-aided manufacturing (CAD/CAM). However, the milling process for the frameworks of removable partial dentures (RPDs) is not easy because they have very complicated shapes and consist of many components...
