CPR for the Worn Dentition: from Concept to Prototype to Restoration

December 30, 2019 by AACD Executive Office

If you’re like most restorative dentists, you’ve been faced with the challenging nature of managing patients with worn dentition at some point in your career, and you probably know that the traditional strategy (utilizing a pre-operative wax-up and going directly to preparation of the teeth for definitive restorations), can sometimes lead to dissatisfied patients who either are displeased with the esthetics, or who have trouble coping with changes in tooth length, form, and/or contour.

 “Knowing the treatment is reversible can help patients feel more comfortable about proceeding.”

CPR Creates Predictability

AACD Accredited Member Dennis Hartlieb, DDS, AAACD, has found success with direct resin bonding in a no-preparation, reversible technique. The direct bonded restorations serve as a prototype, permitting dentist and patient to work out esthetic, occlusal, functional, or phonetic issues before the teeth are irreversibly prepared. The Concept to Prototype to Restoration method (or CPR) enables dentists to treat patients in a safe and reversible manner.

 

Besides being reversible, there are other advantages to the CPR philosophy:

  1. Using transitional bonding generally improves the dialogue between patient, dentist, and laboratory about the patient’s esthetic goals.
  2. The patient is better able to visualize the final product and can “test-drive” the new esthetics.
  3. Patients with financial limitations can opt for more limited treatment using CPR, and costs are often lower due to the predictability in creating the final restorations based on prototypes.
  4. Prototype bonding allows for decreased treatment time, again due to the predictability of the CPR.
  5. Knowing that the treatment is reversible can put patients at ease, making them more comfortable about proceeding with treatment.

Predictability Creates Happier Patients

The traditional strategy for addressing worn dentition is subject to many challenges. With the CPR method, patients can function with a prototype restoration to be certain they are  satisfied with their speech and esthetics. Once both patient and dentist are happy with the result, it can either be maintained indefinitely, resurfaced with a more esthetic composite  layering technique, or eventually transitioned to porcelain restorations.
