Light-cured hollow obturators.

Obturators used in the rehabilitation of large defects of the upper jaw should be easily made to produce a comfortable and stable prosthesis. This goal has been difficult to achieve by using traditional materials and techniques. This article describes a technique to overcome these problems by using a visible light-cured resin. Results indicate that resultant obturators are easily and quickly constructed, and provide a light, comfortable, and well-tolerated prosthesis.

A provisional removable partial denture for use during construction of an anterior splint bar prosthesis.

A technique for constructing a provisional removable partial denture before and during construction of an anterior splint bar prosthesis is described. The provisional prosthesis is easily adapted to fit the splint bar prosthesis after it is cemented in place. The technique assures that the patient will enjoy the benefits of a well-fitting and esthetic provisional restoration through all phases of construction of the splint bar and the final removable partial denture.

Wire-reinforced, light-cured glass ionomer-resin provisional restoration: a description of the technical procedure.

A procedure to use round-wire and glass ionomer-resin cement to make practical provisional restorations is presented. The viability of the use of glass ionomer-resin cement and the need for embrasure perfection in provisional restorations is discussed. This procedure is suitable as a long-term provisional restoration where extensive coronal destruction has occurred. The inherent disadvantage of the procedure is the need to involve occlusal surfaces of the proximal teeth; thus its use is restricted to mouths in which the adjacent teeth are to receive simultaneous restorative treatment.

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.

Front tooth replacement with Tübingen (Frialit) implants.

127 Tübingen (Frialit) implants have been clinically evaluated for a 10 year period. The implants were placed in the anterior region of the maxillae of 101 patients to replace lost incisors, cuspids and premolars. Seventy-seven implants were placed within 3 months after loss of a natural anterior tooth, resulting in the preservation of the volume of the alveolar ridge and the contour of the surrounding soft tissues. This preservation of the volume of the alveolar ridge was due to the fact that the Tübingen implants have conical shapes and sizes, equal to those of the roots of natural teeth. The dentine-like colour and the biological properties of the bio-inert Al2O3 implant-material, in most of the cases was an advantage to the aesthetics of the prosthetic restorations and to the condition of the soft tissues in the permucosal area. The Tübingen implant is placed with a one-phase technique implying special care for the temporary restorations to avoid premature loading. Also prevention of overloading the ceramic material by the fixed restoration needs special attention in the construction of posts, cores and crowns. The overall survival-rate in this study with a mean follow-up of 4.5 years was 87%. Patient and dentist satisfaction was high.

First-stage fixed provisional restorations for implant prosthodontics.

Combination metal-and-acrylic-resin fixed provisional prostheses can be used in implant dentistry as an alternative to a removable provisional prosthesis. They may be fabricated in the laboratory and inserted on the day of fixture placement to ensure that the patients may return to their normal lifestyles with minimal discomfort or interruption in function and esthetics. These interim restorations may be used in free-standing as well as hybrid types of implant supported prostheses. The materials used and techniques of fabrication are described.

Localized scleroderma in a 12-year-old girl presenting as gingival recession. A case report and literature review.

Scleroderma is a connective tissue disorder that displays considerable clinical heterogeneity. This case describes a 12-year-old girl who presented with a localized form of the disease. The consequences were a severe and progressive localized gingival recession affecting two maxillary incisors, a localized lip defect and scarring of the forehead. The case illustrates the difficulties in diagnosis and management of young patients with localized scleroderma.

Prosthodontic therapy for cleidocranial dysostosis: report of case.

Objectives of treatment of the oral manifestations of cleidocranial dysostosis should include restoring the vertical dimension of occlusion, building out the maxilla, establishing of functional occlusion, improving appearance and phonation, and improving the patient's mental well-being.

New technologies, designs and materials for removable maxillary obturator prostheses.

The size and location for maxillary defects influence the difficulty of prosthetic rehabilitation. In all such cases, specially made obturator prosthesis's necessary to restore masticatory function and improve speech, deglution and esthetics. Obturator prostheses vary in size and shape depending on the extent of the defect. Various methods and techniques have been described for the fabrication of removable obturator prostheses. The aim of the present work was to review the progress made in technologies, designs and materials for prosthesis of this type.

An implant-supported rehabilitation case using innovative provisional restoration design and conversion as diagnostic and treatment modalities.

This article reviews and details a maxillary anterior implant-supported rehabilitation case that required an interdisciplinary approach. An innovative technique is presented, in which a transitional acrylic and wrought wire removable partial denture was converted at chairside to a provisional fixed bridge on the day of Stage II implant surgery. This technique underscores and illustrates the importance of diagnosis, planning, and sequential, coordinated treatment in dental rehabilitation.

Provisional removable partial and complete prostheses.

The incorporation of the use of provisional removable complete and partial prostheses is an extremely valuable diagnostic and therapeutic modality in the comprehensive rehabilitation of the partially and fully edentulous patient. There is no question that the use of this restoration addresses many of the chief complaints of patients in a timely fashion and, in so doing, builds a high degree of confidence in the dentist by the patient. The evaluation of the provisional restorations and their subsequent refinement results in a higher quality, more predictable definitive restoration. Experience has demonstrated that postinsertion problems are reduced with the definitive prosthesis following successful therapy with the provisional restoration. The provisional prosthesis is also valuable as a "spare" denture after insertion of the definitive prosthesis. The role of the provisional removable prosthesis is readily understood and accepted by most patients, and the appropriate use of these restorations in prosthetic dentistry is an indication of a high-quality, highly individualized, and service-oriented dental practice.

[Plastic prosthesis for tooth gaps].

Long term observations show, that acrylic partial denture find at the abutments with hook clasps cause more trauma to the periodontal tissues and the denture-bearing area than other removable partial dentures. In this connection it must be considered, whether the acrylic partial denture being a temporary prosthesis, is planned, prepared and manufactured with the same dental and technical accuracy as a definite removable prosthesis. Presuming that the planning, manufacturing, and the shaping of the acrylic partial denture follows the principles of stabilizing function and periodontal hygiene, less trauma on the structures of the masticatory system and therefore an extended indication seems to be possible. To make this evident, the following essential rules of treatment and design are presented: functional impression of the denture bearing mucosa, bite registration, extension of the prosthesis, clasps and recall.
