Dental implants in patients with ectodermal dysplasia

Background and Objective: Ectodermal dysplasia is a hereditary condition in which hypodontiais the second most frequently occurring sign. Hypodontia is associated with lack of development of the alveolar ridge and results in less volume of bone for support of conventional prostheses. Minimal development of the alveolar ridge can affect the bone volume available for the placement of dental implants. This clinical trial evaluated the survival of implants placed in individuals with a form of ectodermal dysplasia and severe hypodontia.Material and Methods: this review has been done by searching in electronic data bases and current released articles using Ectodermal dysplasia and dental implants as keyword.finding:Two hundred sixty-four titanium endosteal dental implants were placed in 51 subjects.Two hundred forty-three implants were placed in the anterior mandible, and 21 were placed in the anterior maxilla with a 2-stage surgical protocol. Either fixed-detachable dentures or bar-clip overdentures were provided. Subjects were followed up for 0 to 78 months after second-stage surgery Of the 243 implants placed in the anterior mandible, 221 (91%) survived. Of the 21 implants placed in the anterior maxilla, 16 (76%) survived. Fourteen of the 51 (27%) subjects had a failed implant. All but 2 failures occurred before or at second-stage surgery. Implant-supported prostheses were provided for all patients.Conclusion:Within the limitations of this study, the results support the continued use of endosteal dental implants in this patient population with appropriate precautions in the maxilla but still furthermore investigations are needed to be conducted to prove the previous results
