Sažetak
A sixty-five-year-old patient came to the Department of Oral Surgery, Clinical Hospital Centre Zagreb after resection of the mandible due to oropharyngeal cancer. Medical history revealed radical neck dissection, commando surgery and reconstruction using the ALT flap due to a squamous cell carcinoma localized in the anterior palate arch with expansion into the retromolar trigonum and lateral oropharyngeal walls (T3N0M0). The patient had recieved chemotherapy (cicplastin i.v.) postoperatively for a total of three cycles in conjunction with radiotherapy. 3-D conformal radiotherapy was performed in the region of the tumour with a total of 32 fractions, with a total dose of 64 Gy, and in the region of the lymph node regions bilaterally with 25 fractions in a total dose of 50Gy. The patient handled the therapy well (ECOG 0), with no major side effects. The only symptom he had was the expected local side-effect, mucositis. 50 µg levothyroxine hormone replacement therapy had also been introduced. On initial examination, a edentulous lower jaw was found with a reduced attached gingiva which prevented high-quality mobile prosthodontic work. A CBCT image was made showing adequate residual alveolar ridge for the implantation of dental implants. After consultation with a prosthodontist, we decided to place three dental implants which would later on retain a complete prosthesis with a individual crossbar. Zimmer Biomet Trabecular Metal ™ implants (4.1mm x10 mm) were placed at positions 31, 35 and 45. Four months after implant placement, the implants were opened and gingiva-formers placed. Two weeks later, the anatomical and functional impressions of both jaws were taken for the production of a new upper partial denture and a lower prosthesis retained on a crossbar. Three weeks later, new dentures were submitted to the patient. No local complications of implant-prosthodontic therapy were clinically observed. The patient reported a significant improvement in chewing efficiency and, consequently, quality of life.
