Assessment of a prosthodontic course for dental hygienists using self-instructional learning modules.

Self-instructional learning modules were used to teach the skill portion of a continuing education course in prosthodontics for dental hygienists. Short- and long-term results obtained from course evaluations and a follow-up survey indicate that dental hygienists are willing and able to extend their traditionally preventive role to include prosthodontic care. The reaction of the course participants to the self-instructional learning modules suggests topics for development of additional learning modules for prosthodontic training beyond the basic dental hygiene curriculum as well as for continuing education.

Perforation and proteinaceous contamination of dental gloves during prosthodontic treatments.

The effect of the type of prosthodontic treatment on glove perforation and proteinaceous contamination of gloves was investigated for 364 prosthodontic treatments using poly(vinyl chloride) plastic (218 occasions) and latex gloves (146 occasions). The amount of protein contamination on plastic or latex gloves varied depending on the prosthodontic treatment performed and the patient treated. As determined directly, it averaged from approximately 800 to 1,500 micrograms per treatment, and the maximum value of protein contamination was more than 4,000 micrograms, corresponding to the amount of protein in 1.5 mL of saliva or 0.1 mL of serum. The perforation of plastic gloves was observed in 83.0% of the total occasions, and the perforation went unrecognized 96.1% of the time. In contrast, the proportion of glove perforation for latex gloves was 12.3% and the proportion of unrecognized perforation of latex gloves was 5.4%. The results suggest that latex gloves are effective in reducing the risk of cross-infection. Nevertheless, prosthodontists still have a potential risk of being exposed to bodily fluids, without being aware of glove perforation, at least once in every 20 treatments, even if latex gloves are worn.

Development and manufacture of prosthodontic components: do we need changes?

PURPOSE: Prosthodontic components for implant treatment have been developed with minimal reported scientific investigation. This paper aims to highlight a number of problems caused by this approach to the development and marketing of prosthodontic components and to suggest solutions. CONCLUSION: Prosthodontic components must be developed with a scientific approach that involves both laboratory and clinical testing so as to optimize treatment outcomes in the future.

Need and effective demand for prosthodontic treatment.

The unmet and met need for prosthodontic services in the United States have been estimated and projected to the year 2000. Based on need-for-treatment estimates within the U.S. population collected by oral examination in 1971 to 1974, some 214.7 million hours of unmet need were estimated. By the year 2000, the projected need is expected to increase to approximately 264.7 million hours (if edentulism is assumed to be zero) or to approximately 293.8 million hours (if prevalence of prosthodontic need is assumed to remain stable). A concomitant rise in effective demand is also expected from 44.7 million hours in 1976 to 1977 to approximately 62.2 million hours in the year 2000. Thus, despite an assumption of declining edentulism, the unmet need for prosthodontic services will remain high.

A study of the adjustment of patients in relation to their prosthodontic problems.

Patients' self-concept and personality have been shown to deteriorate with an increase in prosthodontic problems. This study determined whether patients with prosthodontic problems varying in severity showed different levels of adjustment. Four groups of patients, including a control group, were studied. The three experimental groups differed from the control group and varied in their adjustment in relation to their prosthodontic problems.

Prosthodontic rehabilitation of patients with Class II malocclusions.

The Angle's class II malocclusion patient challenges the prosthodontist because optimal treatment may include orthodontic therapy, orthognathic surgery, periodontics, and fixed or removable prosthodontics. Compromises in the treatment plan are necessary when patients cannot accept optimal dental treatment. However, specific prosthodontic principles should be observed. This article discusses Angle's class II malocclusions, including the theories and therapies to treat patients with this malrelationship successfully. Prosthodontic management of the malocclusion is an adjunct to other care rendered.

Gingival enhancement in fixed prosthodontics. Part I: Clinical findings.

This study assessed the efficacy of a 0.12% chlorhexidine gluconate (CHX) rinse on the enhancement and maintenance of gingival health in patients receiving fixed prosthodontic treatment. Thirty patient participants in this examiner blind study were randomly assigned into two groups, one control and another group using CHX 15 ml b.i.d. in addition to normal oral hygiene. The medication was used for 2 weeks prior to crown preparation, 3 weeks during provisional crown placement, and 2 weeks after definitive crown cementation. Plaque and gingivitis indices were measured initially and at the three aforementioned points during the 7-week period. The plaque index for the control group decreased by 0.26 units; CHX decreased by 0.63 units at 7 weeks. The gingival index of the control group decreased by 0.37 units; CHX decreased by 0.87 units. Adjunctive use of chlorhexidine with fixed prosthodontic procedures significantly reduced plaque levels and significantly improved gingival health compared with the control patients. Fixed prosthodontic procedures alone decreased plaque levels and increased gingival health.

Fixed prosthodontics and esthetic considerations for the older adult.

A new generation of older adults, who are more educated, health-conscious, and economically independent than their predecessors is bringing a fresh perspective and poses unique opportunities and challenges to fixed prosthodontics. Subtle differences in technique, attention to detail, and innovative application of materials and procedures are the main ingredients of successful fixed prosthodontic care for seniors. The goals of fixed prosthodontics for the older adult are fundamentally different from those for a younger population. A practice that enhances the integrity of residual tooth structure while simultaneously creating an environment less prone to dental disease and disability should be emphasized.

Removable prosthodontics: a forgotten part of dentistry.

In years past, removable prosthodontics was a large and highly respected part of dentistry. During the past 50 years, removal of teeth has become less common, and placement of removable complete dentures has become less desirable to dentists. Tooth extraction is now limited to more legitimate reasons than in the past. The result is that removable prosthodontics has lost its appeal to many dentists. Polling large groups of dentists in continuing education courses, I have found that some dentists will not make removable complete dentures, and they do not provide dentures in their practices. Additionally, teaching complete dentures in dental schools has been diluted, because of the necessity to teach many other subjects and the reduced interest in the subject. Are these changes desirable, or should removable prosthodontics receive more emphasis? I discuss the need for dentures in the United States and make suggestions to potentially remedy the current situation.

Prosthodontic management of ridge deficiencies.

The treatment goals in prosthodontics and dental laboratory technology are to provide patients with long-term predictable and esthetic outcomes. The periodontal tissues define the framework that will maintain ridge height, thickness, color, texture, and gingival-tooth frame. The loss of teeth, residual ridge resorption and the loss of gingival tissues continue to affect long-term and esthetic treatment outcomes. Prosthodontic treatment requires consideration of the potential negative tissue effect that time and normal biologic change might have on the completed prosthetic design. This article describes alternative restorative solutions for clinical conditions that have traditionally been managed by surgery, removable prosthodontics, or esthetically compromised fixed restorations. Different clinical conditions for tooth-retained and implant-retained fixed partial dentures as well as the laboratory technology describing construction of these different restorations will be discussed.

Measurement of oral status and treatment need among subjects with dental prostheses: are the measures less reliable than the prostheses? Part II: Treatment need in removable prosthodontics.

Evaluation of treatment need in removable prosthodontics has been an important component of many epidemiologic and clinical oral health surveys. Accurate measurement of need for care enhances health care program planning, quality of care evaluation, and good clinical and health services research. Unfortunately, similar to the measures of oral and prosthesis status discussed in Part I of this review, measures of treatment need in removable prosthodontics have generally been neither reliable nor valid, and have lacked scientific credibility. Part II describes existing measures for treatment need in removable prosthodontics.

Prosthodontic management of the cleft-palate patient.

Unlike some of the disciplines involved in the treatment of the cleft-palate patient, prosthodontics can have application from birth to death. Prosthodontic care never ends. Once surgical care or speech therapy has been completed, the need for follow-up care is ended unless specific problems manifest. With prosthodontic care, not only a restoration of the anatomic, physiologic, and cosmetic deficiencies but also a continual vigilance for signs of dental and periodontal problems must be undertaken. Preventive care is imperative if long-term preservation of the supporting structures and the well-being of the patient are to be attained.

Current prosthodontic practice: a dental laboratory survey.

A survey was distributed to dental laboratory owners at the 1988 annual meeting of the Minnesota Dental Laboratory Association. Current laboratory practice in infection control, the use of nonprecious alloys, the amount of time devoted to complete removable prosthodontics, and complete denture laboratory techniques were surveyed. Responses indicate a moderate level of awareness and compliance with infection control techniques recommended by the American Dental Association, a declining demand for removable prosthodontic services, a high percentage of use of nonprecious alloys, and a very high rate of porcelain occlusion requested by dental practitioners. Comparisons with other laboratory surveys and the implications of these results for undergraduate education in prosthodontics are discussed.

Prosthodontic biomaterials and adverse reactions: a critical review of the clinical and research literature.

Prosthodontic biomaterials include impression materials, luting cements, and restorative materials. They consist of metals and alloys ceramics, and polymer materials and are retained in patients for <60 min or for decades. Oral release of compounds from biomaterials occurs, and adverse reactions may follow dental treatment. Especially in allergically vulnerable patients contact allergy may occur. There are reports from many different countries on contact allergy from gold/palladium alloys, components from polymer-based materials, chromium/cobalt alloys, and nickel. Notifications on adverse reactions in Norway, Sweden, and England are handled by a registry in which patient reactions and occupational exposure are recorded. Data from The Adverse Reaction Unit in Bergen and Umeå have been a most valuable basis in extending knowledge in a field of current interest in dentistry. A review of the clinical and research literature relating to prosthodontic biomaterials and adverse reactions shows that reliable methods seem necessary to expose the frequency of adverse reactions in general dentistry, including prosthodontic treatment.

Prosthodontic complications of Spline dental implants.

Access to accurate clinical data on the frequency of prosthodontic complications encountered in dental implant restorations can provide dentists with important information for evaluating dental implant systems. The complication of prosthetic screw loosening, for example, has often been ignored or under-reported. Only limited published clinical data exists on the use of the Spline connections for dental implant restorations. This paper reports on an in-vitro investigation of prosthodontic complications encountered with the Spline dental implant system restored by students and residents at The Ohio State University's School of Dentistry. From a comprehensive list of implant patients generated from the University's computer records, an extensive chart review was conducted, and all patients who were treated with Spline dental implants were entered into the study. During a second chart review, data on all prosthodontic complications with Spline implant restorations were gathered on reporting forms then entered into a computer database and subjected to statistical analysis. The results showed that 95.75% of the prostheses were free of any complications. Iatrogenic factors that resulted in screw loosening were identified. Based on the findings of this relatively short-term study ranging from 29 to 59 months of post-restoration clinical follow-up, Spline dental implants provided a stable implant prosthetic connection.

Denture status and need for prosthodontic treatment among institutionalized elderly in Denmark.

The purpose of the present study was to estimate the realistic need for prosthodontic treatment among institutionalized elderly in Denmark. The study population comprised 486 elderly in nursing homes and 199 in hospital long-term care facilities. The realistic need for treatment was estimated on the basis of the normative and the perceived needs, taking into account the general mental and physical state of each individual as assessed by the charge nurses. The investigation revealed that the majority of the elderly were markedly handicapped, two-thirds were unable to care for themselves, and 15% were in poor mental condition. Among the residents of nursing homes 67% had a normative need for prosthodontic treatment, e.g. new dentures, relining and/or corrections of occlusion, as compared to 71% of the elderly in hospital long-term care facilities. However, only 19% of the nursing home residents and 32% of the elderly in long-term care facilities has a realistic treatment need. The differences between the two groups of elderly are explained by differences in age and general health status. It can be concluded that the realistic need for prosthodontic treatment among institutionalized elderly in Denmark is far from being met, and that this problem can only be solved if given higher priority by the political decision-makers.

Discrepancy between need for prosthodontic treatment and complaints in an elderly edentulous population.

Most reports indicate that about two-thirds of the elderly population have poor oral health but that only about one-third complain of a problem. The reason for this discrepancy has never been explained adequately. The objective of this study was to estimate the need for prosthodontic treatment in an edentulous elderly population, and to identify factors associated with complaints, needs for treatment, and the use of dentures. Interviews and examinations were conducted to determine the oral health and dental concerns among 269 residents of longterm care facilities in Vancouver. The need for prosthodontic treatment was considered under theoretical, clinical, and practical conditions, and related to various factors that might help to predict this need. During the interview, about half (54%) of the sample identified a problem, and 83% of the subjects were either using a denture with a major fault or were missing a denture. Seventeen percent of the sample would not benefit from treatment because of a severely resorbed residual ridge, while the presence of a complaint combined with a prosthodontic need indicated that about one-third (36%) would seek and benefit from treatment. The proportion of subjects with complaints was larger among the more educated subjects, and among those who had been recently to a dentist. It was not possible to predict the need for treatment from any of the socioeconomic factors considered. No significant association was observed between the need for treatment and the complaints, and many subjects seemed to be resigned to their discomfort or had unrealistic expectations from their dentures.

Current trends in removable prosthodontics.

BACKGROUND: This article discusses trends in the demographics and treatment of the edentulous patient. It is clear that there still is a tremendous need for removable-prosthodontic services today. While the basic process of making dentures has changed little over the past several decades, new materials and techniques can help laboratories and clinicians provide functional, esthetic restorations that offer exceptional value to patients. Implant treatment is a tremendous adjunct to removable prosthodontics in the treatment of edentulous patients, but it is not within the financial reach of all dental patients. CLINICAL IMPLICATIONS: The clinical skills required to deliver excellent complete denture care are also paramount to successful implant prosthodontics (fixed and removable) and esthetic dentistry. Even so, the opportunities to develop these skills and the interest appear to be decreasing at the same time that the need is projected to increase. In service to our patients, the profession must examine this trend closely.
