Implant to reshape maxillary tuberosity area after 3rd molar extraction?

Had 16 extracted 4 months ago (I'm 29) with small bone fragment. Partial bony impaction, crown tilted forward and out to cheek such that bucc. and mass. had to work around it to chew/talk (but function was fine - removal was for minor gum infection). After, face showed unilateral thinning (dntist thinks bone loss and muscle atrophy to be the cause). Platysma and pterygoids are constantly tight, cheek sagging forward.Are there implants that can mimic the bulge of a tooth and reshape the jaw?
