CASE REPORT Eight-Year Follow-Up of a Fixed-Detachable Maxillary Prosthesis Utilizing an Attachment System: Clinical Protocol for Individuals With Skeletal Class III Malocclusions Erica Dorigatti de Avila1* ˆ Luiz Antonio Borelli de Barros2 Marcelo Antonialli Del'Acqua3 Sergio Sualdini Nogueira1 Francisco de Assis Mollo Jr1 The aim of this article is to describe a successful clinical protocol for prosthodontic rehabilitation of a patient with a skeletal Class III malocclusion using a fixed-detachable maxillary prosthesis supported by 6 implants and the MK1 attachment system. The patient was followed up for 8 years. A 46-year-old edentulous woman with a skeletal Class III malocclusion expressed dissatisfaction with her old existing maxillary denture from an esthetic point of view and frustration regarding its function. A fixed-detachable maxillary prosthesis using the MK1 attachment system was made. The patient was followed up clinically and radiographically for 8 years. No bone loss, fracture of prosthetic components, or fracture of the prosthesis was detected in that period. A fixed detachable maxillary prosthesis using the MK1 attachment system is a treatment option for patients with Class III malocclusions who opt not to undergo orthognathic surgery. Key Words: attachment systems, dental implants, overdentures INTRODUCTION D ental implantology has opened up great possibilities in oral rehabilitation. Similarly to other specialties, the philosophy of implant dentistry has changed.1 The percentage of mandibular implant success ranges between 90% and 99%, depending on the time of observation and 1 Department of Dental Materials and Prosthodontics, Arara˜ quara Dental School, Univ Estadual Paulista, Araraquara, Sa o Paulo, Brazil. 2 Department of Social Odontology.

Supported prostheses have been indicated for the rehabilitation of fully edentulous patients since the 1960s, mainly for restoring the edentulous mandible. This preference is related to the instability of conventional prostheses, which results from the physiologic process of alveolar ridge resorption after the teeth have been lost.8 Implant-supported overdentures are also a viable treatment option for the fully edentulous maxilla.9 Among the indications for an overdenture are deficient retention, unstable prosthesis, poor bone quality, and low economic status of the patient. Overdentures offer many advantages comJournal of Oral Implantology 307
