Typodont teeth: maxillary and mandibular premolars and molars were prepared in various crown preparation designs: MO/DO/MOD inlays, MOD onlay, partial crown, full crown.

  • Mean tooth structure removal was assessed by gravimetric analysis.

Results

  • Full crown preparations: 67.5-75.6% (depending on the type of margin preparation)

  • ==Onlays: Fall between inlays and full crowns in terms of tooth removal.==
