What's the difference between the Prime plan and the Professional retiree plan?

If you purchase the Prime plan, you will be purchasing the Dental Care coverage separately from the Extended Health Care coverage – so there are two quotes. However, when you purchase one of the three options of the new Professional Retiree plan, you get a quote for both Health and Dental combined. Also, the Prime plan lifetime maximum for claims outside Canada is reduced to $25,000 at age 65, while it remains the same under the new Professional Retiree plan.
