CASE REPORT Rehabilitation of a Patient With Mandibular Resection Using Osteointegrated Implants: A Case Report Sema Murat, DDS, PhD* Ayhan Gurbuz, DDS, PhD Kivanc Kamburoglu, DDS, MSc, PhD This case report details a 65-year-old male patient who underwent mandibular resection and radiotherapy as treatment for squamous cell carcinoma of the right mandible. The patient was rehabilitated with an implantsupported fixed partial denture and a maxillary occlusal ramp. The patient has been wearing his prosthesis for 2 years with no complaints. Key Words: mandibular resection, tooth-implant connection, maxillary occlusal guide INTRODUCTION M anagement of malignant tumors of the tongue, floor of the mouth, mandible, and adjacent areas represents a challenge for the clinician. Resection of the site, together with large parts of surrounding structures and regional lymphatic tissue, is often required. However, this may result in impaired speech and articulation; difficulty in chewing and swallowing; retrusion and deviation of the mandible towards the surgical side, with altered movement due to loss of continuity of the mandible and motor and sensory deficiencies of the jaw and lower lip; compromised control of salivary secretions; facial asymmetry; and severe cosmetic disfigurement.1–3 Surgical treatment must often be combined with radiation therapy, which further worsens oral functioning. Opportunities for dental treatment are limited by the lack of tissue support following surgery, which tends to severely inhibit the stability and function of conventional dentures. Given the importance of avoiding unnecessary trauma to the mandible caused by mobile dentures and retaining healthy soft tissue coverage in order to prevent bone exposure and osteoradionecrosis, a fixed prosthesis may offer the best solution.2,4 One of the basic objectives of rehabilitation is to retrain the muscles for mandibular denture control and repeated occlusal approximation. Due to the unstable interocclusal relationship that results from lack of posterior support and vertical overlap, it is important to provide the patient with a mandibular positioning and guidance device to help establish an acceptable interocclusal relationship in centric occlusion and during lateral movement so as to improve mastication and mandibular function.4 However, neither reconstructive surgery nor conventional prosthodontic techniques have been able to address these problems successfully. A combination of appropriate reconstruction and implantsupported or implant-retained prosthodontics such as a tooth-implant supported fixed partial denture (FPD) may provide better oral rehabilitation in terms of both function and esthetics.4–6 This article describes the treatment sequence and considerations in the rehabilitation of a patient with an implant-supported fixed prosthesis together with a palatal guide ramp-positioning device following mandibular resection and radiation therapy.
