#CMT# #/CMT# The device has a placeholder (70) provided with an outer counter, which is equal to outer contour of holding elements. The placeholder has an anchoring recess or anchoring projection (74) in an area (72), which corresponds to an outer side area of the holding elements. The placeholder has a locking projection (80) or a locking recess in another area (78), which corresponds to another outer side area of the holding elements. The placeholder is divided or subdivided along a separating plane (86). #CMT#USE : #/CMT# Device for keeping-free a retaining space during production of fixed and detachable dental prosthesis for the accommodation of a retaining element for securing detachable dental prosthesis at a fixed dental prosthesis against unintentional loosening in a withdrawal direction. #CMT#ADVANTAGE : #/CMT# The device has a placeholder provided with an outer counter, which is equal to outer contour of holding elements, where the placeholder has an anchoring recess or anchoring projection and a locking projection or a locking recess, and hence avoids damages of dental prosthesis. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a placeholder element. 70 : Placeholder 72,78 : Areas 74 : Anchoring projection 80 : Locking projection 86 : Separating plane. |
