[QUOTE="Boksa, post: 168620, member: 12984"] I suggest that the tooth preparation for a full crown should have 4 mm or more of near-parallel axial walls from the gingival margin to the occlusal table, and that retentive tooth preparations should have no more than 20 degrees of lack of parallelism. Such retentive tooth preparations do not need bonding when planned for full-zirconia or zirconia-based restorations. Later, I'll discuss the few situations in which zirconia-based, full-zirconia, and lithium disilicate restorations may be better when bonded and resin cement is used. [/QUOTE]
