The record of path of insertion on the dental cast is part of the dentist's work authorization to the dental laboratory technician. The path of insertion record enables the dental technician to replace the cast on a surveyor in the same position that the dentist selected. Analysis of factors that influence the path of insertion should determine a path of insertion that will reduce the potential for dislodgement and promote stability of removable partial denture (RPD).
The recording of the relation of a cast to a dental surveyor and the transfer of this relationship to the dental laboratory may be done by tripodization, by scoring the base of the cast, or by cementing a reference pin on the cast.
Recording the established path of insertion can be difficult when the procedure uses a cemented pin and the casts are mounted in an articulator. This article describes a procedure for innovative dowel pin and sleeve device to record the path of insertion of RPDs, which serves the same purpose as the cemented pin but can be easily removed and replaced.
在牙模上记录就位道是牙医给口腔修复技师的工作授权的一部分。就位道记录能使口腔修复技师将牙模在观测仪上放置于牙医选定的相同位置。对影响就位道的因素进行分析应能确定一条就位道,该就位道可降低可摘局部义齿(RPD)脱位的可能性并促进其稳定性。
通过三角定位法、在牙模底座上划线或在牙模上粘结一个参考针,可完成牙模与口腔观测仪关系的记录以及这种关系向口腔修复实验室的传递。
当操作使用粘结针且牙模安装在牙合架上时,记录既定就位道可能会很困难。本文描述了一种用于记录RPD就位道的创新型销钉和套筒装置的操作方法,该装置与粘结针作用相同,但易于拆卸和更换。
