It is my belief that new crowns should immediately be as comfortable as if they were the patient’s own teeth. Creating a method of consistently achieving this result has been my personal goal for years.
In my office, I have experienced that about 50% of crowns are too tight, and the Black Diamond Strips cannot get into the interproximal space to adjust the proximal contacts. Occasionally, the crowns are even too wide to fit into the space between two adjacent teeth, which can be very frustrating to dentists.
In natural dentition, there is microscopic clearance or passive contact between teeth when they are in rest position, which is called Interproximal Relief (IR)*, and when a crown is fabricated, it is necessary to adjust the crown on the proximal contact surfaces to restore IR, and to achieve complete marginal seating for patient comfort and functionality.
Looking to satisfy the demand for both speed and safety with motorized IPR, ContacEZ has unveiled its latest product—SupraDisc. Designed for use with Invisalign®, ClearCorrect, eCligner, Six Month Smiles®, and other orthodontic treatments, SupraDisc offers orthodontists and general dentists a new, safe, and efficient way to effectively perform what has often been a worrisome procedure.
After the cementation of crowns, all the visible cement is removed and floss passes smoothly, making it easy to assume that all of the cement has been cleaned up. But as a final check, when an x-ray is taken, a little piece of resin cement is found just below the proximal contact area, hidden in the subgingival area and stuck to the enamel surface.
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.
Tea or coffee stains between crowded, lower anterior teeth are very common and can be hard to reach with scaler tips. My hygienists worked diligently to remove tiny traces of stains that were inevitably left, but found the task very difficult. This on-going problem inspired me to develop the ContacEZ Pink Strip.
