The GI, or digestive, tract extends from mouth to anus (see the image below). The division of the GI tract into upper and lower is a matter of some confusion and debate.
Dental PPO insurance plans, also known as dental preferred provider organizations or DPPOs, are a popular dental insurance option due to their flexibility in allowing insured members to choose dentists and dental specialists.
DMOÂ® stands for Dental Maintenance Organization. This plan will cover basic coverage like cleanings and x-rays along with regular services like fillings, crowns, root canals, etc. Some services are not covered so review your insurance options. The Dental DMO is known as a DHMO at most insurance companies. DMO vs. PPO Dental Coverage In a DMOÂ® plan, you are forced to select a dentist from a specific list from your insurance company and indicate a primary dentist. With a PPO you can visit almost any licensed dentist. A DMOÂ® plan is like a discount plan. The insurance company contracts with a dentist and the rate you pay a dentist is indicated by a % of coverage. For example, your coverage may state you pay 50% of the service fees for dental work. With a PPO, you may also see coverage which indicates you pay 50% of the fees.
