弹性绷带在乳腺癌术后应用的效果观察

目的　观察弹性绷带在乳腺癌术后应用效果。方法　 4 8例乳腺癌根治术后应用弹性绷带包扎为实验组 ,4 5例用普通宽绷带包扎为对照组。然后 ,对两组患者术后并发症进行观察。结果　实验组患者的并发症明显低于对照组 ,两组比较有显著性差异 ,P <0 .0 5。结论　应用弹性绷带包扎 ,能明显减少并发症的发生 ,促进切口愈合 ,使患者术后术侧上肢功能锻炼可以提早进行。     

后牙两段式可摘局部义齿的设计与制作

目的:改进常规可摘局部义齿设计的不足,增进固位、稳定。方法:采用两段式义齿结构、两个就位方向和插销锁连接固定。结果:义齿的固位、稳定效果明显提高。结论:插销式分段义齿是对常规可摘局部义齿的一种补充,对主基牙过度倾斜、固位要求高的患者,能够明显改善修复效果。     

持续弹性外牵引矫正乳头内陷

目的 探索一种行之有效的、微创的乳头内陷矫正方法。方法 用钢丝、弹簧和塑料注射器制成弹性可调式的乳头内陷矫治器，利用弹性牵引作用，持续牵拉内陷乳头3～6个月。结果 14例患者均得以矫正，并获得良好的近期效果。1例患者因左侧乳头内陷严重，治疗2周时钢丝接近脱出乳头而更换矫治器并延长佩戴时间。随访患者6～12个月。效果稳定。结论 弹性可调式乳头内陷矫治器用于先天性乳头内陷的治疗，近期临床效果较好，为目前较佳的非手术治疗乳头内陷的方法，但其机理和远期效果还需进一步研究和观察。     

Development of a Device for Removing a Partial Denture in a Patient with Scleroderma

Scleroderma is a chronic disease that has been associated with immune dysfunction. One of the oral manifestations is microsomia, a result of collagen deposition in the perioral tissues. The complexity of treating these patients includes limited mouth opening ability, and difficulty inserting and removing dentures due to finger deformity. This article will describe an appliance specially designed especially for scleroderma patients, which facilitates treatment of the patient with removable partial dentures (RPD).     

Malodour in denture wearers: an ill-defined problem

Denture plaque has not been studied to the same extent as dental plaque, and although there are many similarities in microbial composition, there are some significant differences. Denture-induced stomatitis is associated with poor denture hygiene, a more acidogenic plaque and the presence of Candida albicans . Obligate Gram-negative anaerobic micro-organisms, although present in denture plaque, have rarely been specifically investigated. Opportunist pathogens including coliforms and staphylococci have been isolated from dentures. Teeth adjacent to partial dentures are more susceptible to caries and periodontal diseases, perhaps due to an increased plaque buildup at the prosthesis/tooth interface. Little work has been published on malodour associated with dentures. The inert material provides a substratum for the plaque biofilm, which encompasses a range of odour-producing species. The microbiology of the tongue in denture wearers has not been specifically studied. Thus the nature, origin and extent of malodour in denture wearers is ill-defined, but many species capable of producing malodorous compounds are present. The wide age and health range presented by denture wearers further confounds investigation. There is a need for further work in the area, both for cosmetic- and health-associated reasons in the increasing elderly population.     

Early Designs for the Occlusal Anatomy of Posterior Denture Teeth: Part III

Part III of this series of articles, like Part II, reviews the pioneering efforts in the 19th century to improve the quality of artificial teeth. The focus of this article, unlike that of Part II, is specifically modifications in the design of the occlusal anatomy of the 19th century denture teeth, along with the theories of mandibular movement that inspired those modifications. This article concludes the introductory phase of this project, which seeks to unravel the confusing history of the development of (posterior) denture teeth.

Factors influencing survival of reconstructions. Consensus report of Working Group 2

Abstract: In order to evaluate the level of evidence of factors influencing the survival of reconstructions, systematic reviews of the relevant literature were prepared by a group of rapporteurs. The review papers were circulated to the members of the group before the conference and formed the basis for group and panel discussions. Subsequently, modifications were added to the review papers, and suggestions for consensus statements concerning the following topics were prepared and again critically reviewed in the group and in the plenum: Impact of (i) periodontal disease on the survival of tooth-supported reconstructions, (ii) post-surgical factors as supportive therapy on the survival of implant supported reconstructions, (iii) technical and/or biological complications on the survival of different types of reconstructions, (iiii) material choice for reconstructions on the survival of single crowns and fixed dental prostheses.     

义齿PMMA基托表面粗糙度影响的实验研究

目的：研究技工操作因素对义齿树脂基托表面粗糙度的影响。方法：在不同粉液比、充填时期、聚合温度、混合方式以及出盒温度成型的上颌半口义齿基托上选取1.5cm^2范围，按照统一的打磨顺序，由粗到细打磨抛光完成，浸入冷水中，7天后进行粗糙度测试，所得数据经t检验统计处理。结果：在单体含量降低组、丝状期充填组．热处理时直接放入70℃水中维持9h组与对照组相比，均存在显著差异（P〈0．05）。结论：影响PMMA树脂表面粗糙度的制作工艺因素有单体含量降低、丝状期充填和未经100℃高温热处理。
