Identical, unilateral, distal extension base (DEB) maxillary and mandibular casts with a posterior modification area were mailed to 15 Canadian commercial dental laboratories. Each cast was accompanied by a letter explaining the purpose of the study and a request for the laboratory to design a RPD-U and RPD-L framework. The package also included a questionnaire on the techniques commonly used by dentists in the construction of a removable partial denture prosthesis, as well as the laboratory procedures they requested from laboratory technicians. Compared to the findings of previous studies by McCracken and others, the results of this study indicate an improvement in the dentists' understanding of the fundamental principles of an RPD framework design. However, the questionnaire also revealed the need for improved communication between the dentist and the technician. The study suggests that the basic principles for the construction and design of removable partial dentures, as taught in dental schools across Canada, must be respected by dentists.
带有后牙修改区域的相同、单侧、远端延伸基托（DEB）上颌和下颌模型被邮寄给15家加拿大商业牙科实验室。每个模型都附有一封信，解释研究目的，并要求实验室设计一个上颌可摘局部义齿（RPD-U）和一个下颌可摘局部义齿（RPD-L）框架。包裹中还包括一份关于牙医在制作可摘局部义齿修复体时常用技术的问卷，以及他们要求实验室技术人员采用的实验室程序。与麦克拉肯等人之前的研究结果相比，本研究结果表明牙医对可摘局部义齿框架设计基本原理的理解有所提高。然而，问卷也显示出牙医与技术人员之间需要改善沟通。该研究表明，加拿大各地牙科学院教授的可摘局部义齿制作和设计的基本原则，牙医必须予以遵循。
