我国复杂可摘局部义齿修复的发展现状与问题

可摘局部义齿修复是口腔修复学的重要组成部分 ,是适用范围非常广泛的修复设计。近年来 ,随着固定义齿与种植义齿修复技术的发展 ,可摘局部义齿修复在口腔修复中所占比重有所下降。另一方面 ,可摘局部义齿修复的水平也有了较大提高 ,功能与美观恢复更加完善 ,舒适度更加理想。尽管如此 ,在可摘局部义齿 ,尤其是复杂的可摘局部义齿修复过程中 ,仍存在着一些问题。为此 ,中华口腔医学会口腔修复学科专业委员会 1 999年秋在成都主办了全国复杂可摘局部义齿修复专题研讨会 ,与会专家就复杂可摘局部义齿修复的现状与发展等问题进行了深入的讨论。…

Construction of a Custom-Shaded Interim Denture Using Visible-Light-Cured Resin

A patient treatment is presented to demonstrate a technique using visible-light-cured (VLC) resin to create a characterized denture base for an interim denture. This indication for characterization is routinely seen with African-Americans with dark-pigmented gingiva. Using a combination of blue VLC tray resin and pink VLC denture base resin, the mixture achieves a darker-colored denture base. This technique was used for the fabrication of an interim denture for a patient who required an immediate interim denture. The prosthesis was worn during the healing phase and allowed the patient to function while the definitive prosthesis was being fabricated.     

Resilient Attachments as an Alternative to Conventional Cast Clasp Removable Partial Denture: 3-Year Follow-up

The present clinical report describes the prosthodontic management for a patient with uncontrolled bleeding and diabetes mellitus treated with a maxillary complete denture and a mandibular partial fixed dental prosthesis designed to interface with a removable cast framework partial denture retained by 2 ERA attachments. This approach was undertaken to improve both retention and stability of the distal extension Kennedy Class I removable partial denture. The rehabilitation provided better anterior esthetics than if treated with a conventional clasp retained removable partial denture, by employing a simple, practical design and offering a significant biomechanical advantages, restoring both oral health and function. Thus, this treatment modality, involving an ERA system and transfixation in fixed crowns, is an effective treatment and can be indicated as a clinical alternative for edentulous and partially edentulous patients with systemic disorders or for patients in economic situations that might preclude implant-based rehabilitation.

     

In Practice Evaluation of a Denture Adhesive Using a Gnathometer

PURPOSE: This study measured the extent to which the performance of a maxillary complete denture can be improved with the use of a denture adhesive. This in-practice evaluation assessed both a quantitative measure (force until dislodgement), without and with the adhesive, and patients' perception regarding the use of adhesive. MATERIALS AND METHODS: A total of 194 patients (77 men, 117 women) who wore maxillary complete dentures were tested for denture performance both without and with denture adhesive. A simple gnathometer was used. Patient perceptions were also assessed by a questionnaire and analyzed for denture performance as well as the effects on speaking and chewing, fit and comfort, and perceived confidence. RESULTS: There was a 63.4% improvement in bite force dislodgement with the use of a denture adhesive. A total of 79.2% of the patients perceived better denture performance (bite force dislodgement) with adhesive use. A total of 55.7% perceived an improvement in speaking and chewing. A total of 56.2% noticed the fit and comfort were better. A total of 63.9% responded that they had improved confidence. Conclusions: Use of a denture adhesive can improve the incisal (or protrusive) biting force for patients who wear a maxillary complete denture. Subjectively, the patients reported an improved perception of denture performance and that the use of adhesive provided greater confidence when using the prosthesis.     

Denture satisfaction and clinical performance in a paediatric population

Objectives. The objectives of this study were to investigate the clinical performance of partial upper dentures in children and to assess reported denture satisfaction in this young population. Design. This was a retrospective study using patients’ dental records in conjunction with a postal questionnaire. Setting. The Paediatric Dentistry Clinic, School of Clinical Dentistry, Sheffield. Sample and methods. Fifty‐eight children (aged 7–17 years) who had been provided with a partial upper denture to replace one or more missing permanent incisors were included in the study. The patients’ dental records were examined for the following details: tooth type missing, presence of retained incisor roots, aetiology of tooth absence, age at which the denture was first provided, total time period dentures had been worn, and frequency and type of any denture repairs or replacements. Next a short questionnaire was sent to each child, which sought an evaluation of several parameters of denture satisfaction including: overall attitude towards wearing a denture, denture appearance, ease of eating, comfort and perceived degree of teasing from peers. Visual analogue scales (VAS) were employed to provide a graded response. Results. 70·7% of subjects had a single missing incisor and trauma was the most common cause of tooth loss (77·3%). The mean age at which patients started wearing a denture was 11·6 years and the mean length of time dentures had been worn, at the time of the investigation, was 2·1 years. A ‘T‐shaped’ denture was most commonly employed (77·5% of dentures). Overall, 36·2% of subjects had required at least one denture repair, 28·2% presenting within a year of denture provision. One or more denture replacements had been received by 60·3% of the patients, and 43·6% had required this within a year. Component failure was highest for the denture tooth (40% of repairs) and a change in the patient’s dentition necessitated a denture remake in 66% of cases. VAS scores for parameters of denture satisfaction indicated an overall positive evaluation of the dentures, with the most positive response relating to ease of eating. However, the reported degree of teasing was high and increased with time. The only significant difference for denture satisfaction according to gender was for mastication: girls reportedly found eating easier than did boys. Conclusion. Children are generally accepting of upper partial dentures, but their poor clinical performance is of concern and there is need for improvement.

The Split Denture: Managing Xerostomia in Denture Patients: A Case Report

Wearing complete dentures can be an extremely uncomfortable experience for the people with Xerostomia. Various treatment modalities have been suggested in the literature to overcome the problem of xerostomia in complete denture patients. Incorporating reservoirs containing salivary substitutes, into dentures, is one of these treatment modalities. This paper presents case report of a patient suffering from xerostomia who was successfully treated with a new form of reservoir dentures. This new split denture technique resulted in a reservoir denture that provided good lubrication of the oral tissues, was easily cleaned by the wearer and was produced from routine denture materials. Details of its design, construction and other potential applications are also presented.     

Prosthodontic Management of Segmental Mandibulectomy Patient with Guidance Appliance and Overlay Denture

Patients who undergo segmental or hemi-mandibulectomy suffer from various postoperative problems in esthetics and function. The solution to such problem is providing a mandibular guidance appliance to correct mandibular deviation to resected side due to loss of muscle action on the affected side. This article describes the treatment of a female patient who underwent segmental mandibulectomy on right side secondary to adenoid cystic carcinoma of the base of tongue. An acrylic guidance appliance was constructed to help control the mandibular deviation and co-ordinate masticatory movements. The prosthesis was worn continuously by the patient for 1 month which corrected the occlusion on the left side. To compensate for the open-bite caused due to rotation of mandible following partial mandibulectomy, an overlay removable partial denture was given. The patient was satisfied with the improvement in esthetics and mastication.
