Ectodermal dysplasia (ED) is an inherited disorder characterized by abnormality of ectodermally derived structures. A recurrent oral finding is oligodontia, which in turn leads to a severely hypotrophic alveolar process with typical knife-edge morphology and adverse ridge contours. This unfavorable anatomy can seriously hamper proper implant placement. Fresh frozen bone (FFB) allografts have been recently proposed to augment the residual bone volume for implant placement purposes; however, scientific evidence concerning the use of FFB to treat ED patients is absent. Similarly, data reporting computer-aided template-guided implant placement in medically compromised patients are limited. Thus, the purpose of this report is to illustrate the oral rehabilitation of a female patient affected by ED and treated with appositional FFB block grafts and consecutive computer-guided flapless implant placement in a two-stage procedure. Fixed implant-supported dental prostheses were finally delivered to the patient which improved her self-esteem and quality of life. During the follow-up recall 1 year after the prosthetic loading, the clinical examination revealed healthy peri-implant soft tissues with no signs of bleeding on probing or pathological probing depths. The panoramic radiograph confirmed the clinical stability of the result. Peri-implant marginal bone levels were radiographically stable with neither pathological bone loss at the mesial and distal aspect of each implant nor peri-implant radiolucency. Within the limitations of the present report, the use of FFB allografts in association with computer-aided flapless implant surgery might be considered a useful technique in patients affected by ED.
