Dental PPO (Preferred Provider Organization or Participating Provider Organization) plans are perhaps the most common type of managed care dental insurance plans. Most Dental PPO plans require you to pay a deductible. With a Dental PPO plan the patient typically obtains care through a network of dental providers who agree to serve the plan's members at reduced rates. When you use a network provider, you will typically pay a certain percentage (e.g. 20%) of the reduced rate, and the insurance company will pay the remaining percentage (e.g. 80%).
 
As a member of a Dental PPO plan, you may use dentists outside of the Dental PPO plan network, but you will typically only be reimbursed based on the amount that a network dentist would have accepted as payment in full. The rest of the total charges will be considered the patient's responsibility.
