Doctors often have to evaluate the amount of occlusal clearance on a crown preparation with their naked eye. This inaccurate method frequently leads to insufficient clearance, causing either a need for embarrassing second impressions or the fabrication of fragile, short-lived crowns.
PrepSure is used to confirm that the proper amount of reduction has been performed on crown abutments—neither insufficient nor over-reduction—to avoid necessitating metal occlusion and prevent premature crown breakage. This, in turn, maximizes the longevity of the crowns and prevents hypersensitivity after crown seating.
Sometimes a dentist is called upon to provide a crown under the clasp of an existing partial denture when significant dental decay has developed on the abutment tooth.
I needed an instrument to guide and confirm the occlusal clearance mechanically to create ideal abutments every time for every patient. This avoids all the guesswork and any further waste of costly chair time, which could compromise an otherwise excellent patient experience.
And with that, PrepSure was born.
