Pre-prosthetic surgery is a treatment whereby a favorable oral environment is created to ensure better denture and/or crown seating and retention. Pre-prosthetic surgery encompasses many different types of surgery, including hard/soft tissue crown lengthening, torus/exostosis reduction, alveoplasty, vestibuloplasty, frenectomy, or gum grafting, done prior to the fabrication of dentures, crowns, or other prostheses.
