CASE REPORT Replacement of Mandibular Posterior Teeth With Implants in a Postmandibular Resection Case: A Case Report Jayanth Christian, MDS* Manita Grover, MDS Padmanabhan Thallam Veeravalli, MDS This case report describes the prosthetic rehabilitation of a patient who was treated for ameloblastoma by segmental resection of the mandible. Because of the size of the defect it was decided to use a healing obturator to facilitate bone formation in the defect. At the end of 3 months, bone formation had led to complete obliteration of the defect with an almost complete fill to the crest of the ridge. The next phase of the treatment was prosthetic rehabilitation. The patient preferred a fixed replacement of teeth as opposed to a removable option. The final treatment plan was an implant-supported fixed prosthesis that was progressively loaded. Key Words: ameloblastoma, obturator, progressive loading INTRODUCTION I mplant-retained fixed prosthesis is proving to be a viable and preferred treatment option for patients with a single missing tooth or a few missing teeth. Newer implant systems, treatment options, and diagnostic capabilities as well as better technology have enabled a more predictable result for rehabilitation with implants. Many benign lesions cause mandibular swellings, including ameloblastoma, radicular cyst, dentigerous cyst, keratocystic odontogenic tumor, central giant cell granuloma, fibro-osseous lesions, and osteomas.1 Ameloblastoma is a locally invasive benign odontogenic tumor that is commonly seen in the mandible. There are three forms of ameloblastomas, namely, multicystic, peripheral, and unicystic tumors.2 The tumor is often asymptomatic and may be detected during the course of routine radiography. A painless expansion of the jaw is the usual Sri Ramachandra Dental College, Faculty of Dental Science, Chennai, India. * Corresponding author, e-mail: drjayanthchristian@gmail.com DOI: 10.1563/AAID-JOI-D-11-00024 210 Vol. XXXIX /No. Two / 2013 clinical presentation, and marginal resection is the most common treatment of choice for patients with ameloblastoma.3 Depending on the location and extent of the lesion, jaw resection leads to varying degrees of impairment in appearance, speech, mastication, and deglutition and effects on the patients’ quality,4 It has been reported that endosseous implants can be successfully placed in jaws reconstructed with titanium mesh tray and particulate bone graft.5 Rehabilitation with implants after jaw reconstruction not only improves oral function but also the patient’s psychosocial wellbeing.6 CLINICAL REPORT A 23-year-old female patient reported to the Department of Oral Medicine of Sri Ramachandra Dental College and Research Institute, Chennai, with the chief complaint of swelling of the mandibular right posterior region. On examination, a bony hard swelling was seen in the mandibular right posterior region with tooth displacement. The swelling was diagnosed as ameloblastoma and was treated by segmental resection of the mandible (Figure 1). The
