This case report is an attempt to describe clinical and laboratory
steps for the fabrication of a Maxillary obturator using a combination of PEEK,
Polymethyl Methacrylate (PMMA), and Silicone for a patient with Aramany Class
II defect.
Polyethertetherketone (PEEK) has been advocated for medical use
for many years because of its unique mechanical and biological properties.
Recently many researchers proposed and successfully demonstrated the use of
PEEK as a material of choice for various prosthodontic treatment modalities. We
report a case of a 37-year-old male patient with the primary complaint of
hypernasality and discomfort due to a partial maxillectomy performed for
squamous cell carcinoma. Clinical examination revealed an Aramany Class II
defect. The patient was presented with partial maxillectomy with Aramany Class
II defect and seeking treatment to improve his speech, mastication, and
function. PEEK was chosen as a material of choice for the fabrication of the
framework based on properties like biocompatibility, inertness, low density,
and ease of processing. PEEK can be successfully used combined with acrylic
resin for the fabrication of a definitive obturator and is a good substitute
for conventional materials like cobalt-chromium and titanium alloys. The direct
retainer components of the PEEK framework showed acceptable retentive
properties. Also, the weight of the prosthesis was significantly reduced.
Overall, the patient was satisfied with the function, esthetic, and comfort of
the prosthesis.
