[Application of surveyor in designing partial denture. 4. Partial denture designing and preparation of master model for duplication in surveyor].

The article "Partial denture designing and preparation of master model for duplication in surveyor" is the last of four articles from a series which deals with application of surveyor in designing partial denture. The aim of this article is to describe partial denture designed as "step by step method". The operation with the surveyor, which supposes obligatory analysis of stady casts in order to prepare the supporting tissues, determination of the optimal part of denture insertion and finding of 2 heights of contour, gives this concept a biological character. Such designed partial dentures meet the prophylaxis requirements and have desired retention; they are comfortable and look well. As the suggested concept of partial denture design in surveyor represents the present achievements, in the conclusion of this paper its obligatory application is suggested.

The influence of denture design on patient acceptance of partial dentures.

A study was designed to investigate the influence of denture design on patient acceptance of partial dentures. A total of 317 patients provided with partial dentures by the Department of Prosthodontics, Newcastle Dental School 2-3 years previously, were asked to complete a postal questionnaire about their use of these dentures. Denture status and partial denture design for these patients was established using hospital records. Design variables included material, the number and distribution of replaced teeth, denture support and connector design. In all, 86% of patients (273) returned the questionnaire. A total of 393 partial dentures (210 upper, 183 lower) had been constructed for these patients; 99 (25%) dentures were never worn and a further 57 (15%) dentures were only worn occasionally. Non-wearers were more likely to have no replacement anterior teeth, fewer replacement teeth and, in the lower, a lingual bar. When a multivariate model including all recorded variables was constructed using multiple logistic regression analysis, the presence of anterior replacement teeth for all dentures and the number of replacement teeth for upper dentures were found to be the only significant positive influences on denture wearing. Use of a lingual bar did not influence denture wearing habits.

Removable partial denture design: importance of clinical variables.

A study was conducted to ascertain the influence of clinical variables on removable partial denture design. Dentures were first designed using only the information usually available to technicians, namely, surveyed, articulated study casts. These designs were then modified using information available to the dentist, that is, clinical variables. Of the 208 dentures analysed, 80 (39%) needed modification to 171 components because of patient-related variables. This high number of modifications reinforces the position that removable partial denture design should be instigated and guided by the dentist.

Removable partial denture design in Alberta dental practices.

Studies published in the dental literature have found, all too frequently, that dentists do not pay adequate attention to the design of cast removable partial denture frameworks. This study investigated removable partial denture design in Alberta dental practices. The authors considered various issues related to surveying, partial denture design, and provider education, as well as the possible collaboration of clinical dentistry with denturism in removable partial denture treatment. Although the study found that a significant proportion of Alberta's dentists get involved in designing the cast framework, relatively few undertake surveying. Instead, surveying tends to be deferred to dental technicians. As was the case in other studies, no clear reason for this trend emerged, and it appeared to be unrelated to remuneration or time utilization issues. Responding dentists perceived that their undergraduate education was adequate for providing removable partial denture care. The study also identified a need for small, hands-on continuing education courses. About half of the respondents indicated that it is appropriate for dentists to collaborate with denturists on complete denture care. However, very few respondents considered it appropriate to refer to, or collaborate with, denturists in removable partial denture care.

A three-part bilateral swinglock design denture revisited.

This case was first reported by one of the authors in 1987, subsequent to the patient being treated using a combination of a hinge and split pin sectional denture. The same patient attended for review some 14 years later for assessment of this denture at which stage a replacement was made.

Microcomputer-aided removable partial denture design.

A microcomputer-based program for the design of removable partial dentures is described that has an interactive user interface to conduct a heuristic search of removable partial denture design data and produces computer-generated design graphics. The program is useful educationally and clinically.

Variations in a removable maxillary partial denture design by dentists.

Fifty-seven different removable partial denture designs for a patient were submitted by 57 dentists. Many designs were adequate to provide true health service for the patient. Others, however, could prove detrimental if worn by the patient. Dentists should be concerned with partial denture design if patients are to have prostheses that are functional and compatible with the oral environment.

Pontic design and localized ridge augmentation in fixed partial denture design.

The endpoint of fixed prosthesis design is an esthetic and functional pontic that is compatible with soft-tissue health. In the posterior segment, where esthetics is not as critical, a sanitary pontic form is most compatible with function and hygiene. In the maxillary anterior region, a properly contoured modified ridge-lap pontic design constructed of glazed porcelain most readily fulfills both the esthetic and physiologic requirements. Although the ovate pontic form may satisfy esthetic demands to a greater degree, this is often at the expense of underlying soft-tissue health. In maxillary edentulous regions, ridge deformities may preclude a good pontic fit and esthetic result and dictate the need for surgical augmentation of the collapsed ridge. Selection of the appropriate surgical procedure and graft material depends on the nature and extent of the defect and availability of donor tissue. The subepithelial graft employing the tunnel approach is appropriate when augmentation in only a labial dimension is necessary. When the employing the trapdoor approach or full thickness gingival onlay graft may be employed. In large defects, sequential grafting procedures may be necessary to achieve the desired result. An esthetic and functional result can be attained through proper execution of an appropriate surgical technique and adherence to the principles of proper pontic design.

The influence on partial denture design of a teaching video for general dental practitioners.

This evaluation was based on replies from a random sample of general dental practitioners who were asked to complete questionnaires before and after being sent a video and accompanying booklet on partial denture design. Forty per cent (257) of the original sample (636) completed and returned both questionnaires. A total of 212 respondents (82%) felt the video had been of value and 175 (68%) said they would be more likely to provide metal partial dentures after having watched it. The positive effects of the video were greatest amongst the most recently qualified. Despite some improvement after watching the video, there remained 105 (40%) who indicated that they would leave all partial denture design decisions to the technician on at least some occasions. Comparison of data from first and second questionnaires showed little evidence of substantial shifts in choice of denture design for a series of specific situations. It was concluded that whilst the programme had been well received and had produced changes in intention, there was less objective evidence of change.

An evaluation of training general dental practitioners in partial denture design using a computer-assisted learning program.

The authors of this paper produced a computer-assisted learning (CAL) program on aspects of partial denture design which covered the topics of surveying, support and indirect retention. Version 1 of the program was evaluated by 65 general dental practitioners, the majority of whom did this at their own homes or practices whilst the rest came in to the School of Dentistry. Participants were of varied ages and computer experience. A total of 85% of the participants found the program easy to use and 78% claimed the program had improved their knowledge of partial denture design, although less than half thought it had improved their practical skills. Opinions varied on which of the three topics were the most useful, and interest in future CAL material for dentistry was high. The study shows that CAL can be an acceptable, effective and enjoyable form of training for general dental practitioners who have access to modern microcomputers.
