And Function

The selective laser melting technology is an additive digital method that permits producing metal frameworks for removable partial dentures. The existing literature has compared this technique with the classic technique in terms of precision, quality of fit, and function. This work describes a clinical case of a metal framework produced by the selective laser melting technique in a patient rehabilitated with a removable partial denture. No adjustments were required when the metal framework was inserted, showing good adaptation and stability to the abutment teeth and surrounding tissues. Further studies are necessary for a significant assessment of this technique’s clinical applicability.

Novel Method

The removable partial denture framework is very complex in shape with many curved surfaces, which is a very important assistant tool in prosthodontics. Generally, frameworks are fabricated by single piece basing on mould by traditional cast technology, which has many shortages of multiple steps, time cost and defects such as sand adheres, inner holes, cracks and segregation etc. As a novel method, selective laser melting (SLM) rapid prototyping technology has the advantages of short manufacturing cycle, high precision and flexibility, simple fabrication arts, which can be used to replace the conventional cast technology in the areas of prosthodontics. A SLM system was designed and developed by ourselves, which is consisted of an Yb-fiber laser, an optical scanner, a powder coating device, a gas purification system and a control system, the process parameters were investigated systematically and optimized, finally fabricated removable partial denture frameworks with stainless steel and titanium materials successfully by using the SLM system under optimized parameters. The tests showed that the frameworks have an average dimension precision of ±0.172mm. The wearing experiments on the plaster mouth molds demonstrated the removable partial denture frameworks fabricated by SLM can be fully applied to clinic after some post- processing procedures.

Background: Distal extension edentulism can affect the patient’s ability to function as a dentate person. A well-made removable partial denture that has appropriate extensions, borders and ridge-to-dentition relationship will benefit the partially edentulous patient by providing increased comfort and improved dental function. This article described a patient who had a bilateral distal extension removable partial denture in both upper and lower arch. The prosthesis showed a successful rehabilitation with proper function and aesthetics. Methods: A Kennedy class I bilateral free end saddle edentulous arch in both upper and lower arch was rehabilitated with removable cast partial denture. The case had the reasonable amount of crown: root ratio for the remaining abutment teeth for placement of metal framework, occlusal rest and cast clasp. Results: The delivered denture showed proper sitting of occlusal rest and cast clasp. Retention and stability was acceptable. Occlusion had achieved its desired occlusion scheme. Conclusion: Removable cast partial denture is a suitable option for the rehabilitation of partially edentulous case if the case has such amount of abutment teeth remaining with healthy periodontal condition.

The Stability

A partial removable denture is a device that allows the patient to recover from a partial edentulism. This case report describes the realization of a chrome–cobalt partial removable denture by using two different realization methods: (1) analogic framework and (2) hybrid framework. This allowed us to compare the stability, retention as well as clasp quality of both the products and to highlight their respective advantages, disadvantages, and limitations.
