RESUMO
INTRODUCTION: Axenfeld-Rieger syndrome (ARS), also known as Rieger syndrome, is a rare autosomal dominant condition defined by craniofacial, ocular, dental, periumbilical, and systemic anomalies. CASE PRESENTATION: This case report describes in detail a multidisciplinary approach to successfully restore the oral function and esthetics of a 22-year-old patient diagnosed with ARS. The patient's clinical evaluation revealed that the area corresponding with teeth #13, #12, #11, #21, #22, and #23 was occupied by four malformed and/or deciduous teeth. The four anterior teeth were extracted, and socket preservation was performed using bovine-derived porous bone mineral. Six months after extractions, two implants were placed in the location of the lateral incisors and additional bone graft was performed. Two months after the initial healing, a temporary fixed partial was delivered and 9 months after implant placement the implants were restored with a porcelain-fused-to-metal fixed partial denture. CONCLUSIONS: The use of implant-supported fixed partial dentures to restore missing teeth in patients with ARS provides biological and mechanical advantages over conventional, fixed, or removable prosthodontics. Further evaluation is needed to determine the longevity and long-term prognosis of dental implants in patients with ARS.

Implant-supported restorations in the upper anterior segment need to meet biological, functional, and esthetic requirements to be successful. Bone availability and soft-tissue characteristics in the area of implant placement are crucial for achieving maximum success. This article describes the steps involved in replacing a fractured upper central incisor with an implant-supported crown. Using surgical techniques involving extraction socket preservation/augmentation and connective tissue grafting, ideal positioning of the implant was possible and gingival contours were idealized. With this multiple step treatment, the final restoration met biological and functional requirements and its esthetic results were maximized.
