Treatment of missing mandibular 4 incisors is often thought to be easier then other place during surgical and prothetic procedure. But clinicians encounter unexpected difficulties such as restricted implant site due to mesio-distal width of mandibular incisors, limited space as a result of crowing and mesial drift, esthetic problem after severe alveolar bone resorption, and difficulties of provisionalization Through cases, possible treatment options for missing mandibular incisors would be discussed. Treatment options for missing mandibular 4 incisors Place narrow type implant or one body mini implant on exact tooth position when there is no bone resorption Regular size implant on interseptal bone area when there is severe bone resorption Consider using resin bonded bridge(resin retained bridge/resin bonded fixed partial denture) as a tentative prosthesis when patient resists extracting remaining incisors with poor prognosis.
