The process of fabricating a denture usually begins with an initial dental impression of the maxillary and mandibular ridges. Standard impression materials are used during the process. The initial impression is used to create a simple stone model that represents the maxillary and mandibular arches of the patient's mouth. This is not a detailed impression at this stage. Once the initial impression is taken, the stone model is used to create a 'Custom Impression Tray' which is used to take a second and much more detailed and accurate impression of the patient's maxillary and mandibular ridges. Polyvinylsiloxane impression material is one of several very accurate impression materials used when the final impression is taken of the maxillary and mandibular ridges. A wax rim is fabricated to assist the dentist or denturist in establishing the vertical dimension of occlusion. After this, a bite registration is created to marry the position of one arch to the other.
Fifty-four complete-denture wearers were interviewed one year after they had been fitted with the dentures. Their opinions and reactions were noted and the answers given to standard questions were analysed for inter-correlations and for correlations with findings in earlier series of clinical and roentgenological investigations. Most of the patients were satisfied with the fit, aesthetic effect of the denture and ability to chew and speak. Many of the patients reported oral parafunctions. Roughly every fourth patient used sedatives because they felt restless and nervous.
Typically, a removable partial denture is made of a metal framework with pink plastic to replace the gum tissue and plastic or resin denture teeth. The number of missing teeth and their location will affect the comfort and stability of the removable partial denture. The use of dental implants may increase the stability of a removable partial denture, or dental implants may be the best solution for replacing the missing teeth.
An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
