The recent economic downturn has made it necessary for clinicians to rethink some of the options presented to patients when faced with a dental emergency. This is especially true when lifelong patients suddenly find themselves out of work and in need of dental care.

One of the best services a clinician can provide for patients is the intraoral repair of fractured porcelain or porcelain-fused-to-metal (PFM) crowns. With the high-quality bonding and composite products available today, the end result is an esthetic and functional repair that is feasible, low-risk, cost-effective — not to mention an appreciative patient. With the hope of an economic turnaround, it is important to hold on to these patients. By helping these patients through the difficult times with cost-saving options, their trust and loyalty will be back in the office in the ”good times.”

Surface preparation

  1. Isolate adjacent tissues and restorations with Etch Arrest acid-neutralizing barrier. Leave Etch Arrest in place for duration of etching.

Etch and silanate

  1. Apply Porcelain Etch by slowly expressing an even coat onto prepared porcelain and/or metal for 1.5 to 2 minutes. Suction then thoroughly rinse and dry surface.

  2. Apply Ultra-Etch 35% phosphoric acid for 5 seconds. Suction then thoroughly rinse and dry surface.
  3. Porcelain will have a frosted appearance. Repeat if necessary.
