Rebonding Tooth Fragments | Conservative Dentistry Auckland

Post by Dr. Clarence P. Tam, HBSc, DDS, FIADFE, AAACD

Hello all,

You know your Tuesday is going to be a doozy when this calls and walks in through the door.  Virgin tooth snapped off (uncomplicated enamel-dentin fracture: MIDBL tooth 11) when the patient was removing her Invisalign aligner and she is understandably frenetic.  MIDBL fragment intact on the DIBL aspect but missing a section on the MIBL aspect.  Shade selection pre-operatively: Kerr Harmonize A1E, A2D.  Caries detector used to ensure a hard dentin base before micro air abrasion (27 micron aluminum oxide) on both fragment and preparation/fractured tooth with isolation using a serrated metal strip.  Selective etch technique using G-Premio Bond + DCA (dual cure activator) on both tooth and fragment left uncured before luting the two together using G-Cem Linkforce.  Reverse layering completed (facial to palatal) as defect more significant on palatal aspect using A1E and A2D in a histoanatomical fashion.

Definite dehydration, but here's to hoping the fragment rehydrates into esthetic invisibility in a few days' time.  Fit like a glove in the Invisalign aligner *phew*.
