Long term observations show, that acrylic partial denture find at the abutments with hook clasps cause more trauma to the periodontal tissues and the denture-bearing area than other removable partial dentures. In this connection it must be considered, whether the acrylic partial denture being a temporary prosthesis, is planned, prepared and manufactured with the same dental and technical accuracy as a definite removable prosthesis. Presuming that the planning, manufacturing, and the shaping of the acrylic partial denture follows the principles of stabilizing function and periodontal hygiene, less trauma on the structures of the masticatory system and therefore an extended indication seems to be possible. To make this evident, the following essential rules of treatment and design are presented: functional impression of the denture bearing mucosa, bite registration, extension of the prosthesis, clasps and recall.
长期观察表明，带有钩式卡环的丙烯酸树脂局部义齿对基牙牙周组织和义齿承托区造成的创伤比其他可摘局部义齿更大。就此而言，必须考虑作为临时修复体的丙烯酸树脂局部义齿在设计、制备和制作时是否具有与确定性可摘修复体相同的口腔和技术精度。假定丙烯酸树脂局部义齿的设计、制作和塑形遵循稳定功能和牙周卫生的原则，那么对咀嚼系统结构的创伤就会更小，因此似乎可以扩大其适应证。为了阐明这一点，现提出以下基本治疗和设计规则：义齿承托黏膜的功能性印模、咬合记录、修复体伸展范围、卡环以及复诊。
