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.

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

regardless of the system used and the degree of
resorption.2-5 Nevertheless, in the maxilla, survival
currently ranges from 85% to 95% 6,7 depending on
the type of bone and degree of resorption.
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
