Objective:To evaluate the treatment plan,clinical outcome and related problems in patients with congenital missing teeth.Methods: From November 2000 to February 2009,thirty seven patients with congenital missing teeth underwent thorough diagnostic workup,treatment planning and an interdi-sciplinary approach to ensure optimal treatment in Department of Implant Dentistry,Peking University,School and Hospital of Stomatology.A standard follow-up protocol was conducted for all the patients.Results: The enrolled cases in this study were classified in to 3 types: single tooth missing,multiple teeth missing and edentulous.Among them single tooth missing was found in 21 cases,multiple teeth missing was found in 12 cases and 4 cases were edentulous.120 implants were placed and restored in 37 patients with the mean follow-up 39.3 months(10-109 months) after prosthetic functioning.Two implants lost after function about 6 months and the remaining implants functioned well until the last review.No adverse complications such as pain and nerve trauma was observed and the mean bone resorption was 1.91 mm.Conclusion: An interdisciplinary approach ensures optimal treatment for patients with conge-nital missing teeth.Implant restorations provide an alternative way with predictable clinical results.
