Dental Implant-Supported Prosthetic Rehabilitation With Custom Attachment in a Patient With Partial Maxillectomy Defect Because of Osteosarcoma: A Case Report.

Prosthetic rehabilitation in maxillectomy patients aims to separate the oral and nasal cavities to provide adequate articulation, restore the contour of the midface, and provide acceptable aesthetic results. This clinical case report describes prosthetic rehabilitation via placement of dental implants in the zygomatic bone in a patient who underwent partial maxillectomy because of osteosarcoma. The success of obturator placement after maxillectomy requires retention by the surrounding dental tissue or dental implants. When zygomatic implants cannot be used, dental implants placed in the zygomatic bone and attachments fastened to these implants can easily provide the retention and stability required by the obturator.

Role of cone-beam computed tomography in the evaluation of a paradental cyst related to the fusion of a wisdom tooth with a paramolar: A rare case report

Fusion is an abnormality of tooth development defined as the union of two developing dental germs, resulting in a single large dental structure. This irregular tooth morphology is associated with a high predisposition to dental caries and periodontal diseases. As a result of recurring inflammatory periodontal processes, disorders such as periodontal pocket, pericoronitis, and paradental cysts may develop. A rare mandibular anatomic variation is the retromolar canal, which is very significant for surgical procedures. The fusion of a paramolar and mandibular third molar associated with a paradental cyst co-occurring with the presence of a retromolar canal is rare, and the aim of the present study is to describe the evaluation of this anatomical configuration using cone-beam computed tomography.
