The HT has been used in some secondary care settings for temporary management of partially erupted permanent molars affected by molar incisor hypomineralisation. However, there are currently no clinical trials to support this use. If practitioners are considering using the HT as a temporary non-AGP measure for permanent molar teeth, there are a few points, besides the lack of supporting evidence, that they should consider. Firstly, the crowns should only be placed on teeth that are not yet in occlusion. Secondly, the HT in this cas , unlike primary teeth HT use, provides only a temporary solution until more definitive restorative treatment and this will necessitate an AGP to remove the crown. Finally, permanent tooth preformed crowns are less easy to fit than those for primary teeth and almost always need to be trimmed with scissors, crimped and polished.
