可摘局部活动义齿是一种修复牙列缺损的大众化传统实用方案,尽管价格平民化,但由于微笑或言语时唇颊侧金属卡环臂的暴露而缺乏美感,造成了患者不愿选择,且不少医生也缺乏热情设计、专业体会肤浅,活动义齿几乎成为不美观修复体的代表。如何按不同层次需求,设计改良各档次美观活动义齿修复方案,挖掘各种可行修复技术方法,有效地提升活动义齿修复的美观效果,已经成为我国修复专业下一步发展思路中不能继续淡忘的专业途径。本文将对不同类型档次的美观活动义齿进行总结归纳,为美观活动义齿修复的临床应用提供参考。

目的对下颌单侧游离缺失后三种不同修复体的运动及其受力状态进行试验性研究。方法首次采用电子散斑干涉术（ｅｌｅｃｔｒｏｎｉｃｓｐｅｃｋｌｅｐａｔｅｒｎｉｎｔｅｒｆｅｒｏｍｅｔｒｙ）对单端固定桥、铸造三臂卡环及ＲＰＩ卡环的可摘局部义齿进行垂直加载测试，观察显示的实时散斑干涉条纹图并测量相应各截面牙槽骨的离面位移（ｏｕｔｏｆｐｌａｎｅｄｉｓｐｌａｃｅｍｅｎｔ）。结果表明三种修复体修复后均有利于应力的传递，相应截面牙槽骨的离面位移减少。其中单端固定桥修复后相应牙槽骨的离面位移量最小，ＲＰＩ卡环较三臂卡环可摘局部义齿修复后相应牙槽骨的离面位移量稍大。结论电子散斑干涉术特别适用于测量小而不规则牙槽骨表面的变形情况。合理选择适应证，单端固定桥是一种良好的修复方式。     

A method for assessment of quality of life in relation to prosthodontics. Partial edentulism and removable partial dentures

The aim of this study was to evaluate the possible use in prosthodontics of a method for an interview technique allowing maximal individuality within the cultural boundaries. The impact of partial edentulism and removable partial denture (RPD) wearing on quality of life was chosen as the target question. The interview included patient generated selection of five quality of life cues. The current status/intensity of each cue was measured by use of a Visual Analogue Scale (VAS), the relative weight/importance between the cues by a direct-weighting (DW) instrument, and a summarized quality of life score was calculated. One hundred and one participants with partial edentulism with or without RPDs were included in the study. No correlation was found between the VAS- and DW-scores, indicating that different aspects are measured with these two instruments. Sixty to seventy per cent of the participants answered positively to questions about the test method, including self-knowledge, consciousness and identification of needs and wishes. The 'Schedule for the Evaluation of Individual Quality of Life - Direct Weighting' turned out to be a useful instrument for assessing patients' priorities, and fulfils in many ways the demands for individualized problem identification, decision-making and treatment planning. The results of the comparison of RPD wearers and non-RPD wearers showed that aesthetics is a major factor and that the overall quality of life between the experienced RPD wearers and non-RPD wearers in this study did not differ significantly.     

A systematic review of prosthetic restoration in patients with shortened dental arches

The literature regarding the effect of prosthetic restoration in patients having distal extension edentulous space in posterior area (shortened dental arch: SDA) is reviewed in the following article. Information retrieval followed a systematic approach using PubMed. Articles in English published between 1966 and March 2011 describing the outcome of treatment with various prostheses were evaluated. From the search results of 98 articles, 21 articles met the inclusion criteria. Treatment with removable partial dentures (RPDs) improved masticatory function, patient satisfaction and oral health-related quality of life (OHRQoL). However, no significant difference was found in the outcomes between patients with RPDs and with cantilever fixed partial dentures (CFPDs). Caries developed more frequently after treatment with RPDs than CFPDs. The time to survival for CFPDs was not longer than that for RPDs, while more visits to maintain RPDs were required than for CFPDs. No significant difference was found in masticatory function, OHRQoL, and occlusal stability between patients with RPDs and those without restoration of missing molars. Consequently, treatment with RPDs for SDA seems to be less advantageous than CFPDs or no restoration for missing molars. Further research is required to validate treatment with implant-supported fixed partial dentures for SDA.     

Removable Partial Denture in Combination with a Milled Fixed Partial Prosthesis as Interim Restorations in Long-Term Treatment

Interim restorations are frequently used in prosthodontic treatments. Many complex situations require the combination of fixed and removable partial prostheses. An appropriate interim restoration design that accurately implements the treatment plan is necessary to prepare the oral cavity for the prostheses, and to contribute to the preservation and health of remaining natural teeth, bone support, and gingival tissues. This report describes a modified technique for construction of interim restorations with a combination of fixed and removable partial prostheses. The technique consists of the construction of a milled fixed prosthesis and removable partial denture with metallic framework for use during extensive treatment, improving masticatory function and esthetics and preserving the periodontal health of supporting structures. This interim restoration can also serve as a template for the definitive restoration, allowing patient and dentist to evaluate appearance and function and helping to ensure the success of the definitive restoration.     

Using a Visible Light‐Polymerized Resin to Fabricate an Interim Partial Removable Dental Prosthesis

An interim partial removable dental prosthesis (RDP) is any dental prosthesis that replaces some teeth in a partially dentate arch designed to enhance esthetics, stabilization, and/or function for a limited period of time, after which it is to be replaced by a definitive dental prosthesis. This article describes a technique that uses a visible light‐polymerized (VLP) resin as the base material for an interim partial RDP. This technique can be easily accomplished in a dental office or laboratory and results in a predictable dental prosthesis. This technique eliminates the need for laboratory processing.     

Enhancing Student Learning of Removable Prosthodontics Using the Latest Advancements in Virtual 3D Modeling

When educating dental students or prosthodontic residents, a picture can be worth a thousand words. If that is so, then what could enhanced 3D modeling be worth relative to enhancing student learning? The answer is undoubtedly more than what a picture can provide. That is why the use of 3D models has become increasingly common with respect to patient care. The 3D modeling allows the patient to visualize more clearly the proposed treatments and outcomes; however, while 3D modeling has started to make an appearance in dental education, many of the current 3D modeling techniques do not offer the flexibility needed for dental education and enhanced student learning. At the University of Iowa, the use of 3D modeling software has enabled the creation of 3D models that can be altered or customized to be used in a more flexible way to teach students in the arts and complexities of removable partial denture (RPD) design and associated components. This educational technique article will: (1) demonstrate how these 3D models can be used to enhance student perception and learning regarding RPDs; and (2) will demonstrate using videos and web‐based portals to show how the 3D RPD models were created and then used for educational purposes.

Maxillary Rehabilitation Using Fixed and Removable Partial Dentures with Attachments: A Clinical Report

Despite requiring dental crown preparation and possible root canal treatment, besides the difficulty of clinical and laboratory repairs, and financial burden, the association between fixed (FPD) and removable partial dentures (RPD) by means of attachments is an important alternative for oral rehabilitation, particularly when the use of dental implants and FPDs is limited or not indicated. Among the advantages of attachment‐retained RPDs are the improvements in esthetics and biomechanics, as well as correction of the buccal arrangement of anterior teeth in Kennedy Class III partially edentulous arches. This article describes the treatment sequence and technique for the use of attachments in therapy combining FPD/RPD.
