PROBLEM TO BE SOLVED: To provide a scaling connector exchange method that enables a scaling connector of a correction device to be replaced at low cost and quickly.SOLUTION: A scaling connector exchange method includes: gypsum wall creation step S1 of arranging and solidifying gypsum around a scaling connector mounting portion so as to become a gypsum wall for surrounding the scaling connector mounting portion of a pair of divider plates gypsum lid creation step S2 of arranging and solidifying gypsum in a recess and its perimeter so as to become a gypsum lid for closing the recess surrounded by the gypsum wall scaling connector exchange step S3 of exchanging a scaling connector by removing the gypsum lid from the recess and its perimeter, and excavating the scaling connector mounting portion resin polymerization step S4 of polymerizing resin by injecting the resin in an excavation hole and attaching the gypsum lid to the recess and its perimeter and scaling connector mounting portion mending step S5 of mending a surface shape of the scaling connector mounting portion by removing the gypsum lid from the recess and the perimeter and removing the gypsum wall from the circumference of the scaling connector mounting portion.SELECTED DRAWING: Figure 16COPYRIGHT: (C)2017,JPO&INPIT【課題】矯正装置の拡縮連結具を安価かつ迅速に交換することができる拡縮連結具交換方法を提供する。【解決手段】一対の分割プレートの拡縮連結具取付部分を囲う石膏壁となるように拡縮連結具取付部分の周囲に石膏を盛り付け凝固させる石膏壁作成工程S1と、石膏壁によって囲まれる凹陥部を閉塞する石膏蓋となるように凹陥部及びその周囲に石膏を盛り付け凝固させる石膏蓋作成工程S2と、石膏蓋を凹陥部及びその周囲から取り外し拡縮連結具取付部分を開削して拡縮連結具を交換する拡縮連結具交換工程S3と、開削孔にレジンを注入し石膏蓋を凹陥部及びその周囲に装着してレジンを重合させるレジン重合工程S4と、石膏蓋を凹陥部及びその周囲から取り外し石膏壁を拡縮連結具取付部分の周囲から撤去し拡縮連結具取付部分の表面形状を修整する拡縮連結具取付部分修整工程S5とを備えてなる。【選択図】図16
