The Health Maintenance Organization (HMO) or Preferred Provider Organization (PPO) sets a cap on how much you can charge for the program. By adding HMO or PPO, the dentist agrees to adhere to these restrictions so that companies and patients know the intended cost. Because the costs are under control, the participating dentist may need to control the treatment regimen, the materials used, and the time it may take for the treatment to take place.
