General 1

The option of combining two retainers (where a connector is placed in each pillar tooth), should, if possible, only be used in the frontal area and when replacing premolars.

Further:
During the 'settling' phase of an implant insertion

in the transition time after roottreatment or root tip removal
in the regeneration stage after (a.o.) treatment of Parodontitis (etc.)

Based on high axis- and plane-parallelism-requirements and occlusion disurbances, this combination should be avoided in upper- and lower side dental area.
