Prosthodontic treatment during active osteonecrosis related to radiation and bisphosphonate therapy: a clinical report.

Osteonecrosis of the jaws following the use of bisphosphonate drugs has been reported in the literature. Presently, there is limited evidence to establish guidelines for the prosthodontic management of patients with active osteonecrosis, a history of osteonecrosis, or medical history of using these medications. This clinical report reviews the current literature regarding bisphosphonate use, and reports the prosthodontic treatment of an edentulous patient with active osteonecrosis who had a history of oral bisphosphonate use and jaw irradiation.

Prosthodontic aspects of a new method for functional reconstruction following maxillectomy.

The prosthodontic aspects of a new method of reconstruction after maxillectomy are described. A custom-made titanium mesh tray filled with crushed autogenous hip bone is interposed between two layers of a pedicled temporal muscle flap. The titanium mesh tray is fabricated on a cast carved to represent the anatomy of the reconstructed maxilla. The tray is designed so that, after healing, osseointegrated implants can be placed in preplanned positions in the reformed maxilla. The buccal sulcus is recreated with a free mucosal graft from the contralateral cheek at the second implant surgical stage. The prosthodontic restoration is completed after healing of the free mucosal graft.

Neuropathic implications of prosthodontic treatment.

Associated with prosthodontic procedures, there may be the development of a chronic pain state caused by injury to peripheral branches of the trigeminal nerve. Neuropathic pains have not been discussed in the prosthodontic literature and yet are becoming increasingly common, especially in relation to the placement of implant prostheses. This article reviews the pathophysiologic and clinical features associated with neuropathic pain after dental procedures (traumatic neuralgia). The prosthodontist should become aware of neuropathic pain as a possible complication of treatment and informed consent should be obtained before procedures are started that might damage nervous tissue.

Prosthodontic management of ectodermal dysplasia: a review of the literature.

Ectodermal dysplasia is commonly a difficult condition to manage with prosthodontics because of the typical oral deficiencies and because the afflicted individuals are quite young when they are evaluated for treatment. It is important that these individuals receive dental treatment at an early age for physiologic and psychosocial reasons. This article reviews the literature that pertains to the prosthodontic treatment of the disorder and the review includes considerations in behavior management and timing of treatment.

Measuring fit at the implant prosthodontic interface.

Four centers in the United States and Sweden have been working for 2 years to develop systems and methods for measuring fit at the prosthodontic interface. Two systems are based on stylus contact techniques, one system uses a laser as its reader source, and one system is photogrammetric. All the systems are capable of providing data as three-dimensional x, y, and z axes coordinate values that can be transformed into linear and angular data that characterize the bearing surfaces of abutments or abutment replicas and their mating components in the prosthesis framework. The centroid, a single point computed from the collected data, was the measurement unit, derived for these bearing surfaces, that was used to compare the systems. All four methods can most likely detect misfits that are relevant in the clinical setting; however, only one system can be used intraorally. When any measurement system is assessed, the data should always be examined for repeatability to establish the reliability of the system. This investigation made comparisons among the measurement methods used at the four centers. It was apparent from this study that comparisons of data from measurement systems should be rounded to the nearest 10 microns. The SDs determined in the comparisons were larger than 5 microns and therefore misfits should be calculated in terms smaller than 10 microns. This final point is important to the clinician who relies on research reports about precision of fit when selecting treatment approaches in caring for the implant prosthodontic needs of their patients.

Prosthodontic problems and limitations associated with osseointegration.

When compared with any other surgical or prosthodontic procedure, osseointegration has offered the greatest improvement in quality of life for patients who suffer with the effects of an edentulous condition. Results have been dramatic both functionally and from the aspect of patient satisfaction. However, a level of complication and compromise remains that limits overall patient and practitioner satisfaction. This article critically analyzes the existing literature relative to prosthodontic problems and complications of osseointegration for the edentulous patient. An attempt is made to compare the documented frequency of complication versus the perceived potential for complications, including implant failure, prosthesis misfit, component fracture, and screw loosening.

Complication rate with prosthodontic reconstructions on ITI and IMZ dental implants. Internationales Team für Implantologie.

The aim of this study was to compare the complication rate of two implant systems with different prosthodontic concepts: rigid conical or resilient support of the suprastructure. In 66 patients, 138 ITI implants were inserted whereas 31 patients received a total of 50 IMZ implants. Over an average observation period of 3.5 years (range from 0.5 to 8 years), not only was implant survival recorded, but also prosthodontic complications such as screw loosening, fractures of screws, inserts (intramobile elements, intramobile connectors) and abutments, as well as fractures of metal framework and veneers. With the ITI system, 28.8% of all devices placed exhibited such problems during the observation period. With the IMZ system, this rate was significantly higher (P < 0.05), in that 77.4% of all reconstructions required a repair at some point. The various complications were divided into those occurrences which affected only the suprastructure, i.e., failures of frameworks, veneers, bar devices or other retentive elements, and those which involved implant components per se, such as screws and abutment components. In the first category, adverse effects occurred more frequently with ITI-supported prostheses (15.1%) versus IMZ suprastructures (6.4%). Regarding complications with implant components, the rate with IMZ components was considerably higher (71%) compared with ITI (13.5%). This was mainly due to the presence of intramobile elements (IME) and connectors (IMC) in the IMZ system. In this retrospective study, precise fitting, non-resilient abutment components leading to rigid connections of suprastructures, proved to be clinically more successful than resilient anchoring components.

Quality of written prescriptions and master impressions for fixed and removable prosthodontics: a comparative study.

AIM: Various ethical and legal guidelines require dental practitioners to adequately design, prescribe and fabricate good quality prostheses. The purpose of this investigation was to examine the quality of written instructions and choice of impression trays and materials for both fixed and removable prosthodontics in Ireland and the United Kingdom. MATERIALS AND METHODS: A pre-piloted questionnaire was distributed to a number of large commercial laboratories geographically distributed throughout the United Kingdom and Ireland. Information was sought relating to the quality of written instructions and use of impression trays and materials for three forms of 'dental precision casting' - cobalt-chromium based removable partial dentures, full veneer porcelain-fused-to-metal crowns, and conventional fixed bridges. RESULTS: Six hundred questionnaires were distributed, and information was received relating to 447 items of prosthodontic treatment (response rate= 75%). Ninety-five per cent of cases were privately funded. Using pre-determined grading criteria, poor or no written instructions were provided in one-half of cases examined. One-half of master impressions were made using a plastic stock tray. The technician felt that material had been appropriately disinfected prior to being sent to the laboratory in only 57% of cases. CONCLUSION: The written instructions and master impressions examined in this study failed to meet the relevant ethical and legal guidelines in approximately 50% of cases.

Speech compensation for prosthodontically created palatal asymmetries.

Symmetry of alveolar and palatal contour was altered prosthodontically for five subjects. There was palatographic evidence, for both /s/ and /l/, that the prosthodontic changes were not always compensated for in one week of adaptation. Compensation was more pervasive for /s/ and took the form of preservation of the general orientation of the air channel in spite of the palatal asymmetries present.

Prosthodontic guidelines for surgical reconstruction of the maxilla: a classification system of defects.

Surgical reconstruction of maxillectomy defects has been described as an alternative to prosthetic rehabilitation to close the oral cavity. Advancements in microvascular surgical techniques require comprehensive treatment planning guidelines for functional rehabilitation. This retrospective study evaluated acquired maxillectomy defects after surgical reconstruction and/or prosthodontic rehabilitation in an attempt to establish surgical and prosthodontic guidelines that could be organized into a classification system. Forty-seven consecutive patient treatments of palatomaxillary reconstruction at a single facility, The Mount Sinai Medical Center (New York, N.Y.), were reviewed. All patients were rehabilitated with a tissue-borne obturator, a local advancement flap, a fasciocutaneous free flap, or a vascularized bone-containing free flap. Palatomaxillary defects were divided into 3 major classes and 2 subclasses. The aim of this defect-oriented classification system was to organize and define the complex nature of the restorative decision-making process for the maxillectomy patient.

Alloys for prosthodontic restorations.

The numbers and types of alloys for prosthodontic restorations have increased dramatically over the past 25 years, making selection of an alloy for a given clinical situation difficult. Factors such as cost, the need for better strength, and worries about alloy corrosion have pressured the alloy market to change significantly. A number of properties--including yield strength, hardness, elastic modulus, microstructural phases, grain size, corrosion performance, coefficient of thermal expansion, oxide color, and melting range--are relevant to the proper selection of an alloy for a given clinical problem. In this article, a brief historical look at prosthodontic alloys and the nomenclature for alloys is followed by a discussion of the most important physical properties of alloys for clinical practice. A summary of the types of alloys available today and their classification is then presented. Finally, speculations about future trends for alloys are made, and simple guidelines are suggested to help dentists choose appropriate alloys for their practices. This review excludes implant alloys, dental amalgam, and alloys for orthodontic and endodontic applications.

New paradigms in prosthodontic treatment planning: a literature review.

New treatment modalities have expanded the choices available to prosthodontists and their patients. At the same time, an explosion of data has called into question the validity and efficacy of certain forms of traditional prosthodontic treatment. Together, these factors have greatly complicated the treatment-planning process. The purpose of this article is to provide a framework for the prosthodontic treatment-planning process that incorporates the latest evidence-based information available. A review of the literature was undertaken through a Medline search. Articles published in English from 1975 through 2001 were evaluated; selected articles were chosen for review on the basis of a subjective judgment of their relevancy and significance to the clinician.

Costs of periodontal and prosthodontic treatment and evaluation of oral health in patients after treatment of advanced periodontal disease.

Retrospective estimations of dental care costs of periodontal and prosthodontic treatment and evaluation of oral health in 37 patients with advanced periodontal disease were carried out. Measures of their subjective evaluation of oral health 7-10 yr after the treatment are presented as a health profile and as indices in single numbers. The relations between oral health as an index and the dimensions in the health profile are analyzed. Dental care costs for treatment in the mandible was SEK 35 550, for the maxilla SEK 45 380 and for both jaws SEK 74 230. After the treatment oral health as well as general health were in excess of 75 on a 0 to 100 scale. Chewing ability, comfort and aesthetics were the variables found to significantly affect the subjective oral health. Oral health in terms of periodontal and prosthodontic conditions was maintained over the observation period.

Assessing prosthodontic dental treatment needs in older adults in Thailand: normative vs. sociodental approaches.

The authors compared the estimated prosthodontic treatment needs of edentulous older adults when using normative and sociodental approaches. This cross-sectional study involved a non-random sample of 158 edentulous adults, aged 60 to 74 years, who were living independently in metropolitan Chiang Mai, Thailand. Each subject was given an oral examination and was interviewed. The dental questionnaire and the clinical criteria were adapted from the National Diet and Nutritional Survey for People Aged 65 and Older and included the Oral Impacts on Daily Performances sociodental indicator. Of the 158 subjects, we found using a normative assessment that 79.7% had a treatment need for complete dentures; 60.5% of those adults had impact-related treatment needs. Estimated treatment need dropped by about 40% when subjects were assessed using the sociodental approach. We concluded that large reductions in normative need estimates for complete dentures were apparent using a sociodental approach to assess prosthodontic dental treatment needs of older people.

Attitudes of Victorian dentists to removable partial denture prosthodontics: treatment planning.

A survey of the attitudes of dentists in Victoria to various aspects of the treatment planning phase of removable partial denture prosthodontics was undertaken. Data were analysed and compared with those obtained from an identical study in South Australia. Those Victorian dentists who graduated in the 1960s, those who worked in multiple-practitioner practices, or non-rural areas, and those who had an added interest in removable prosthodontics were more likely to stress the importance of a greater number of attributes than those who graduated in the 1950s or 1970s, or those who worked alone, in rural areas, or had no particular interest in the discipline. Results indicated also that Victorian dentists tended to place greater emphasis on many of the concepts embraced by the questions asked than their interstate colleagues. It is suggested that, in addition to formal education, intraprofessional relationships and interest in a discipline are factors which might influence the concepts and attitudes of general practitioners.
