An evaluation of the effects of two distal extension removable partial denture designs on tooth stabilization and periodontal health.

A 30-month follow-up study was conducted on 36 patients to evaluate the effects of the lingual plate as a major connector in distally extended removable partial dentures (RPDs) on tooth stabilization. At the same time, the study evaluated the effects of lingual plate-type RPDs and lingual bar-type RPDs on periodontal health. The most striking finding of the study was that, with the exception of gingival recession (GR), periodontal conditions improved with both types of RPDs. At the end of 30 months, there were significant differences in plaque index, GR and tooth mobility (TM) values between treatment groups (P < 0.05). Plaque accumulation was greater in the lingual plate treatment group; however, this did not result in periodontal breakdown. There were no statistically significant differences between treatment groups with respect to pocket depth, gingival index or attachment loss (P > 0.05). Moreover, patients treated with lingual plate-type RPDs demonstrated less TM when compared with patients treated with lingual bar-type RPDs at the end of 30 months follow-up. Overall study findings established that with adequate checks on oral and denture hygiene at regular intervals, patients with RPDs may even experience improved periodontal health. Moreover, the clinical interpretation of decreased TM observed in patients treated with lingual plate-type RPDs may be questionable as the plaque accumulation was greater in the lingual plate treatment group inspite of periodic recalls.

Interactive computer teaching/learning in the dental curriculum: partial denture design.

Interactive multimedia is an emerging industry with a broad domain. It operates from a base of computer technology to enable the production, distribution and sharing of ideas. The use of multimedia in the educational setting is in keeping with the concept of learning, rather than teaching and, with this in mind, a pilot program in interactive computer learning has been developed which is geared specifically to the requirements of junior students. The design sequence and philosophy used in this program follow the teaching at Sydney University Dental School. Its purpose is to facilitate students in mastering the technical aspects of denture framework design, leading them through a set sequence of steps from saddle identification to finish. Future plans, using more sophisticated equipment, are to develop more advanced programs for senior (fourth year) students, including applications for treatment planning and also the rudiments of osseointegrated implant work.

The geriatric patient: removable partial denture design, protecting the dentition.

The population of the United States is aging rapidly. By the year 2000, approximately 36 million Americans will be 65 years of age or older. With respect to dentistry, the oral health status of older adults is improving. In addition to retaining more of their teeth, the demand for dental care is increasing amongst the geriatric population. Because total edentulousness is expected to decline in the future, a greater demand for removable and fixed partial dentures is anticipated. This paper serves as an outline for quick reference when treatment planning the replacement of teeth in the partially edentulous arch.

The Twin-Flex removable partial denture: design, fabrication, and clinical usage.

A rationale for the use of Twin-Flex clasps is presented. Twin-Flex clasps may provide improved esthetics, an increased number of clasping sites, and enhanced patient comfort when compared with conventional clasping systems. Two fabrication methods are described, and departures from conventional clasping techniques are explained.

The hinge clasp in removable partial denture design.

As a result of people keeping their teeth longer, modern dentists are encountering more partially dentate patients and difficult restorative problems. It is possible to solve some of the problems caused by the unusual angulations and undercutting when the remaining teeth of partially dentate patients start to drift by using the hinge clasp. The authors describe the types of device available and outline the advantages (and disadvantages) of its use.

Clinical and technical aspects of implant-supported restorations in the edentulous maxilla: the fixed partial denture design.

PURPOSE: The aim of the present article was to describe the treatment planning for an implant-supported maxillary fixed prosthesis and the clinical procedure involved, including the laboratory fabrication sequence. MATERIALS AND METHODS: If patients request a fixed prosthesis to restore the edentulous maxilla, it is essential to decide as soon as possible whether this prosthesis design can satisfy the requirements of esthetics, phonetics, comfort, and function. Thus, the crucial clinical factors need to be checked during examination. Furthermore, the relationships between ideal implant angulation, available bone, and intended crown should be assessed using reformatted computed tomography. RESULTS: In patients with minimal bone resorption and limited intermaxillary space, implants can usually be placed in the prosthetically driven implant position for a fixed prosthesis. To evaluate and optimize esthetics, biology, and function, a fixed provisional restoration should be inserted for a 6-month diagnostic period. The ideal provisional then serves as a guide for the final restoration. CONCLUSION: If clinical and radiologic diagnostics indicate that an implant-supported fixed complete denture is feasible, meticulous presurgical planning, precise execution of implant positioning, and a progressive prosthetic treatment sequence are required. The ceramometal fixed implant-supported restoration can then be established in an ideally prepared and matured oral environment.

Treatment plan for restoring the edentulous maxilla with implant-supported restorations: removable overdenture versus fixed partial denture design.

STATEMENT OF PROBLEM: Restoring the edentulous maxilla with a fixed complete denture or a removable overdenture is a complex and challenging procedure. PURPOSE: This article presents and discusses the crucial factors involved in deciding whether a fixed or removable implant prosthesis should be planned in fulfilling the patient's preference for optimal esthetics, phonetics, comfort, and function. METHODS AND MATERIAL: A concept for treatment planning is presented that enables the practitioner to check the decisive parameters during the first examination and to make the final decision with the help of the reformatted computerized tomography scan. CONCLUSION: If this treatment plan is followed, implants can be placed to comply with the selected prosthetic solution and compromised solutions can be avoided. The fixed design for implant prosthesis is only appropriate for patients with minimal resorption of the alveolar bone and an optimal maxillomandibular relationship. The removable overdenture may be indicated from the outset and is no longer restricted to patients with a compromised situation in which fixed implant prostheses are not feasible.

Use of dental implants to improve unfavorable removable partial denture design.

This study aimed to determine whether the use of a limited number of dental implants, with no rigid connection between implants and teeth and as few as possible prosthetic element requirements, is a viable solution for improving unfavorable removable partial dentures (RPD) design. Fifteen partially edentulous patients with an unfavorable number and distribution of abutment teeth were treated, each with a limited number of implants, from 1997 to 2004, resulting in an improved RPD design. Implant survival rate was 100%, and prosthetic complications were minor. All patients reported great satisfaction with the partial dentures and good chewing efficiency. The results indicate that the use of dental implants to improve unfavorable RPD design is a viable and cost-effective treatment modality.

Removable partial denture design considerations where periodontally compromised teeth exist.

Restoration of a periodontally compromised dental arch with a removable partial denture may require one or more design modifications. Multiple rests ensure that adequate vertical support remains in the event primary abutment teeth are lost. An open or closed base can be strategically placed in the maxillary major connector to facilitate the replacement of subsequently lost teeth. The location of finish lines can be modified to provide a smoother resin-to-metal transition when posterior teeth are lost. Wire direct retainers that provide more physiologically acceptable clasping of compromised teeth and that are easily adjusted and added to the prosthesis should be considered.
