Full-Arch Implant-Supported Fixed Dental Prosthesis
Prosthodontic Case Study
The patient had a complex medical history (immunodeficient), therefore, meticulous oral hygiene was imperative. Appropriate treatment options were presented and informed consent was obtained. The patient had elected to proceed with a complete maxillary denture and a mandibular implant-supported fixed dental prosthesis. The diagnostic phase involved maxillary and mandibular diagnostic set-up and fabrication of a radiographic guide for dual-scan CBCT acquisition and implant planning.
Four Ø4x13mm implants were immediately placed following mandibular clearance and alveolectomy. Good primary stability was achieved with an insertion torque of >35 Ncm and ISQ >70. The implants were immediately loaded with a metal-acrylic provisional prosthesis for 3 months. After osseointegration, adjustments were made to the provisional prosthesis to ensure optimal speech, mastication and access to oral hygiene.
A milled titanium bar was designed according to the provisional prosthesis and a definitive maxillary clear processed-base complete denture and a titanium-acrylic implant-supported fixed dental prosthesis with Phonares (IvoclarVivadent) denture teeth were fabricated. The patient reported superior function including eating corn on the cob, increased confidence, and improved smile and facial aesthetics.
