Combined prosthesis signifies the integration of replacement crowns in combination with a model cast denture on abutments (teeth). They are anchored by telescope crowns and German crowns that can be telescoped with each other. The abutment tooth receives a telescope cap cast of metal. The outer telescope is incorporated in the denture; its shape and colour are adapted to the remaining dentition. A clear advantage in comparison to the clamp denture is that the tooth is completely covered by the telescope and that there are no tearing, pulling movements resp. movements of the tooth within the clamp. A loss of hard substance due to the clamp is avoided as well as a loosening by non axial stress of the clamp tooth.
A telescope tooth is mainly stressed axially. The aesthetic advantage is also on the telescope denture’s side, as no metal parts can be seen in the visible area. If the remaining dentition only consists of the anterior teeth, the so-called ambilateral free-end gap, the production of an attachment is recommended. The anterior teeth are put into a stable crown block that is equipped with an attachment part adjusted distally (to the rear). The secondary attachment part is incorporated in the model cast denture, which creates an invisible transition from the crowns to the denture. Aesthetically no connection element can be seen while laughing and speaking. For telescope crowns and combined crowns there are the same health insurance regulations, for veneering (tooth colour creation of the crowns) as for single crowns. The offered materials are the same. Here as well non-contractual agreements can be arranged against additional charge. |
