The formulation of a design for a removable partial denture framework must be approached in a logical, organized fashion, whether the framework is conventional or designed to support an obturator. The number of abutment teeth, their relationship to one another and to the other teeth in each arch, the location of the fulcrum line if unilateral or bilateral extensions are to be used, the need for direct and indirect retention, and the quality and quantity of the support for the extension bases must all be considered. The occlusal scheme and esthetics should also be considered. Once the design is formulated, careful preparation of the mouth, good impressions, proper fitting of the framework, a good altered cast impression when necessary, careful adjustments at insertion, and patient instructions concerning care and maintenance of the prosthesis will increase the chances of success. All the basic principles must be considered and applied to the unique requirements of the maxillectomy patient.
可摘局部义齿支架设计的制定必须以合乎逻辑、有条理的方式进行，无论该支架是传统的还是用于支撑阻塞器的设计。基牙的数量、它们彼此之间以及与每个牙弓中其他牙齿的关系、如果要使用单侧或双侧延伸则支点线的位置、直接和间接固位的需求以及延伸基托支持的质量和数量都必须予以考虑。咬合方案和美观性也应加以考虑。一旦设计确定，精心的口腔准备、良好的印模、支架的合适就位、必要时良好的模型修改印模、戴入时的仔细调整以及对患者有关义齿护理和维护的指导，都将增加成功的几率。所有基本原则都必须加以考虑并应用于上颌骨切除患者的独特需求。
