Braces, pre-molars extracted, gap closed, is it possible to put dental implants in the old gap if needed?

Depends: Premolar or bicuspid extractions are usually performed in conjunction with orthodontic therapy when there is insufficient space for proper alignment of the teeth. The orthodontist uses the spaces created by the extractions to move teeth into those spaces. If the space created by the extraction is not completely utilized and there is adequate space, an implant can sometimes be placed.

Clarify question: If the space created from the extracted premolars has been closed with orthodontic therapy why would you need an implant ?

-: Yes, as long as there is enough bone present to stabilize them.

Yes: In fact, if orthodontics is used to open the gap first, then typical you will have an excellent situation for a dental implant. The tissue and bone volume and shape should be excellent. The act of moving teeth develops excellent bone where the tooth was (the gap). This will make a dentla implant ideal.

Why?: If the spaces are completely closed, why would you desire the insertion of an implant. If you are asking if the space could be re-opened--i suppose, but there would need to be a very good reason to even consider it.

Depend on size: To place an implant for a premolar you need a space of 7 mm minimum, if not the size of the tooth will be thinner and will not be esthetic.

Extractions: Extractions were done to provide room to properly align teeth over good bone support. If the extraction spaces,are filled with implants, there's no room to properly position your teeth. Ask your Orthodontist to go over your treatment plan with you.
