Description
しかしながら、その挿入路から差し込まれた細い棒状器具がキーパーの裏面に正確に当接するように、挿入路を形成させることは非常に難しいという問題がある。
そこで、可撤式キーパー対応キーパートレーの底面に、その外周部から中心部に向けて所定幅で切欠されて空間に開口した開口部を形成させれば、この可撤式キーパー対応キーパートレーの開口部に、板状の型材をその上面と可撤式キーパー対応キーパートレーの底面の内面とが面一となるようにした状態で、可撤式キーパー対応キーパートレーを石膏模型に盛ったワックス上のキーパー設置位置に載置し、更にワックスを盛って根面板のワックス模型を形成することによって、挿入路の上面にキーパーの裏面を正確に位置させるように根面板を作製することが容易にできることを究明して本発明を完成したのである。
