Brief Summary

This retrospective study investigates the longevity of lithium disilicate based glass-ceramic single tooth restorations placed with IPS e.max CAD and IPS e.max Press after a wearing period of more than 15 years. The primary objective is to assess the survival rate of single tooth restorations with IPS e.max CAD and IPS e.max Press after a wearing period of at least 15 years. The secondary objectives are to assess the quality of the single tooth restorations in regard of aesthetic, functional and biological properties.
