Description
Radan Kassab and Amal Hasan present early clinical observations of a refined tooth preparation protocol for fixed crowns, in a 2026 technical note. Their modified approach shapes teeth below the gumline using piezoelectric ultrasonic tips, then polishes the area with silicone points. Four patients received zirconia crowns across thirty-five teeth.
Crowns went through a strict four step ultra-polishing routine before placement. Gum measures were tracked at one week, then at three, six, and twelve months. Margins stayed stable with no visible recession at any site. Gum thickness rose most in thin tissue, from about 0.59 to about 1.14 millimeters on average. Bleeding stayed minimal across follow-up.
