Will I still have an overbite when I receive my dentures?

Taking anti-coagulants will be a concern. I would suggest seeing a board certified oral and maxillofacial surgeon who does lots of implants. Many of them also have M.D. degrees. Have them do a complete exam and consultation and see what they think your options are.

If you want to compare please compare the recent photos, the photograhs here look with a gap of more than 2-3 years atleast or even more, the extraction space gaps take atleast a year to completely close, i guess you should have taken a proper explantion before the start of the treatment, about...

Yes, placing dental implants and an arch of fully-supported teeth in the upper will restore your natural face shape. Sometimes even more lip support can be given but it depends on the patient.
