I will also have 2 surgical implants placed between other teeth with healing abutments. what can fill in the empty space and not use a flipper?

Depends: If is not an esthetic area it is best to use nothing at all. In the esthetic zone a temporary abutment and crown with no bite on it can be used in some situations.

Not Much: A temporary removable partial denture (flipper) is usually used. Are you wearing anything now? If not, another three or four months will not make a difference. If you are wearing a denture, have your dentist modify it for use over the implants.

“Snap-on” teeth: A suck down retainer with a tooth placed in the missing areas. These appliance must always be removed when you eat food. It's affordable, efficient and comfortable,
