Dental implants and their successful long-term results have begun a new era in dentistry. In recent years, the increasing trend of using dental implants at single-tooth edentulous cases has been taken into consideration. Although treatment goals and objectives are similar for both prosthodontists and orthodontists, they rarely cooperate. Usually prosthodontists are in need of preprosthodontic orthodontic preparations for younger patients. In this paper, different preprosthodontic orthodontic procedures that may be required before the placement of implants at single-tooth edentulous cases are presented. In the first and second cases, decreased mesio-distal space was regained by different orthodontic treatment methods, whereas the occlusal relationship was corrected for better function in the third case.
