Contingency, priority, and risk (CPR) protocol: a roadmap for designing successful and long-lasting implant therapy

Poorly planned implant-supported restorations not only cause discomfort for patients, but they can also seriously damage the intraoral cavity. Sometimes clinicians inherit cases with poorly planned implant-supported restorations, while other times they may create this problem by not addressing a patient's overall condition prior to treatment planning. Clinicians require a realistic approach for designing prostheses in a comprehensive way. The CPR--ie, contingency, priority, and risk treatment planning--technique aids in identifying potential problems and creating a practical treatment option. By addressing the treatment-planning process in this manner, clinicians are better equipped to design successful and long-lasting implant restorations.
