Inclusion criteria
Inclusion criteria: Patients that were included in the initial study (Please also see https://pubmed.ncbi.nlm.nih.gov/16614863/). Patients had to present two large defects of the dental hard tissues suitable for restoration with CGPCs or PCCs and exhibit a moderate to good level of oral hygiene as represented by a papillary bleeding index (PBI) = 35% (Saxer and Mühlemann 1975). Furthermore, the teeth to be restored had to be free of any symptoms of pain, show tooth mobility less or equal grade I (i.e., mobility discernible, but not visible), and the application of rubber dam isolation had to be possible for insertion of PCCs.
Exclusion criteria
Exclusion criteria: Patients not meeting at least one of the inclusion criteria.
