Treatment of open occlusions with onlay and overlay removable partial dentures.

The onlay removable partial denture has the primary purposes of restoration of esthetics and function through a conservative modification of the existing dentition. It is particularly applicable to open occlusion situations and in improving an uneven mandibular occlusal plane. Its use should be supplemented with specific instructions in proper cleansing and maintenance of underlying dentition and the prosthesis and with scheduled recall appointments.

Overlay removable partial dentures for a patient with ectodermal dysplasia: a clinical report.

The orofacial characteristics of ectodermal dysplasia include anodontia or hypodontia, hypoplastic conical teeth, underdevelopment of the alveolar ridges, frontal bossing, a depressed nasal bridge, protuberant lips, and hypotrichosis. Patients with this disease often need complex prosthetic treatment. The options for a definitive treatment plan may include fixed, removable, or implant-supported prostheses, singly or in combination. However, financial constraints and other priorities can prevent patients from choosing the most desirable treatment. This clinical report describes the diagnosis and treatment of ectodermal dysplasia in an 18-year-old man. The treatment included interim removable partial dentures fabricated to establish an acceptable therapeutic occlusal vertical dimension, followed by definitive overlay removable partial dentures and composite restorations.

Maxillary and mandibular overlay removable partial dentures for restoration of worn teeth. A three-year follow-up.

This clinical report describes the fabrication and a three-year follow-up of maxillary and mandibular cast overlay removable partial dentures for the restoration of severely worn dentition with accompanying loss of vertical dimension of occlusion. The frameworks supported porcelain veneers for esthetics, and metal occlusal surfaces for strength and durability.

Maxillary and mandibular overlay removable partial dentures for the treatment of posterior open-occlusal relationship: a clinical report.

This clinical report describes the use of maxillary and mandibular overlay removable partial dentures to treat a patient with class III skeletal malocclusion and a posterior open-occlusal relationship. Overlay removable partial denture therapy was used as an alternative to other options such as orthodontics and combined orthodontic/oral surgery procedures; it satisfied the esthetic and functional requirements of the patient and provided a stable occlusion. Overlay removable partial dentures are a reversible and relatively inexpensive treatment for patients with congenital or acquired anomalies, but the potential disadvantages of these prostheses include compromised esthetics when the dentures are removed; caries and periodontal disease as a result of poor oral hygiene; and veneer material fracture, debonding, discoloration, and wear.

The stereognostic ability of natural dentitions versus implant-supported fixed prostheses or overdentures.

A stereognostic ability test was performed in 60 patients. Forty patients were rehabilitated by means of osseointegrated implants. One group consisted of 20 patients with fixed prostheses on implants in both the upper and lower jaws. The other 20 patients had a maxillary denture while in the mandible an overdenture was retained by means of two implants connected by a bar. They were compared to a group of 20 subjects (controls) with a non-restored natural dentition. For the stereognostic ability test, subjects had to recognise ten different test pieces by manipulating them with two antagonistic incisor teeth, avoiding any contact with other oral structures. Both response time and percentage accuracy of recognition were evaluated. The present findings indicated that subjects with an overdenture on implants did not score significantly different from those with an implant-supported fixed prosthesis. In contrast, subjects with teeth had a significantly better stereognostic ability. The percentage of correct responses was 52% for overdentures, 56% for fixed prostheses on implants and 75% for natural dentitions. From these results, it could be concluded that the stereognostic ability is impaired in subjects rehabilitated with osseointegrated implants by about one-third to one-quarter compared to subjects with natural teeth.

Technical failure rates of double crown-retained removable partial dentures.

Removable partial dentures (RPD) can be retained using conical crowns or parallel-sided telescopic double crowns. The purpose of this study was to evaluate and compare the technical failure rate of the two retainer systems. One hundred seventeen dentures made by dentists of the medical school were included. Seventy-four RPD were retained with parallel-sided crowns (n = 251) and 43 with conical crowns (n = 160). Following the medical report follow-ups from January 1992 to December 1998, technical RPD failures were noted and analyzed. Technical problems occurred during the observation time in 48.8% of the conical retained dentures and 34.2% of the parallel-sided retained dentures. In both cases, loss of cementation was most frequently noted, while loss of the facings occurred only with conical crowns. Other technical failures did not depend on the type of retainer system used. These were most frequently problems with the denture base, e.g., fracture of artificial teeth or the metal framework. We conclude that there were different technical failures of both double crown retainer systems. These problems were not insignificant in number but treatable.

A silicone rubber attachment for primary retention of partial dentures.

A technique for primary retention of removable partial dentures has been described. A soft-tissue-borne restoration provides an increase in primary retention without an increase in forces to the abutment teeth, and the restoration requires a minimal outlay of time and money.

Interim overdentures.

The construction of an interim overdenture using existing removable partial dentures with natural tooth crowns and artificial teeth can be a simple and economical method of providing patients with dentures while tissues heal and teeth are prepared and restored. A more definite prognosis for both the patient and his remaining dentition can be established before the final overdenture is completed. The procedures necessary to provide three types of interim overdentures have been outlined. Patients tolerate this method of changing their dentitions extremely well.

Removable partial overdentures.

A technique for applying the overdenture concept to removable partial denture construction has been presented. Endodontically treated abutments are prepared with cast gold posts and copings over which removable partial dentures with conventional components are fabricated. No special materials or complicated laboratory techniques are required, and the maintenance and repair problems of precision attachments are avoided. A variety of potential uses and advantages of the technique are discussed.
