This case report is to report an extraordinary case of the spontaneous discharge of a dental implant. A 45-year-old woman was referred to our department complaining of symptoms of acute Maxillary sinusitis. She underwent a computed tomography scan that revealed a dental implant dislocated in the maxillary sinus. A preoperative medical treatment [Amoxicillin - Clavulanate (375 mg) and Streptokinase-Streptodornase (12500IU)] three times a day for two weeks was administered in order to prepare her for surgery. Unexpectedly, she reported that she had discharged the implant from mouth in the early morning. Mucociliary clearance in combination with a local osteolytic inflammatory process and mucolytics therapy are the likely causes of this unusual discharge.

Introduction : Patients with temporomandibular disorder may have various ear-related symptoms. If an excessive load is applied to the ear area due to the skeletal shape of the mandibular condyle or malposition of the disc, an auditory problems may occur. Case report : The patient was referred to our clinic due to the suspicion of temporomandibular disorder from the local otorhinolaryngology clinic. A few days ago, his right ear could not be heard. MRI showed that the left TMJ disc was anterior displacement with reduction, the right TMJ disc was anteromedial displacement without reduction. Also Right mandibular condyle showed sclerotic bone change, subchondral cyst and was compressing the frontal wall of the ear on MRI view. Right TMJ arthroplasty was done under the diagnosis of right TMJ osteoarthritis and osteochondroma. Postoperative intermaxillary fixation was done with SAS screw and elastics for 2 weeks. One month after the operation, hearing and TMJ discomfort were recovered without any complications. Conclusions As seen in this case, hearing loss due to benign tumor-like lesions of the temporomandibular joint should be treated surgically to restore the TMJ function and hearing.

Fibrous dysplasia(FD) is a benign fibro-ossifying disease in which fibrous tissue replaces normal bone and marrow. Craniofacial bones, including the maxilla and mandible, are commonly involved. A 7 year-old girl visited the clinic with a chief complaint of gingival swelling around the lower left primary molar. Mild bulging of the lower left periodontal tissue was observed. Not only the mandible, but also the maxilla, zygoma, sphenoid, and temporal bones were affected by FD. Permanent tooth germs were involved in the lesions and facial asymmetry was caused by lower left bone expansion. She was scheduled for a follow-up visit at the department of pediatric dentistry and oromaxillofacial surgery.

The use of an obturator prosthesis for patients with maxillary defects is a common treatment method to improve their oral function and achieve esthetic satisfaction. However, due to various difficulties and complexities, conventional methods for fabricating dental obturators continue to pose a challenge for dentists and patients, as well as laboratory technicians. CAD-CAM technologies may make it simple to fabricate maxillofacial prostheses including hollow obturators, which could improve comfort for clinicians by reducing burdensome manipulations. In addition, patients without a specialist in their vicinity will be able to be treated via cooperation between a nearby general practitioner and a distant prosthodontist. The aim of this clinical report is to investigate the possibility of using digitally fabricated maxillofacial prostheses that can be designed in one location, and manufactured in another in clinical situations.

Maxillary-malar deficiency is the most frequently occurring midface dentofacial deformity. Clinicaly patients with maxillary-malar deficiency exhibit malar and infraorbital rim deficiency and class III malocclusion. For treatment of these deformities, modified LeFort III osteotomy have been used. Modified LeFort III osteotomy advances maxilla with orbital rims and zygomatic bone anteroposteriorly. This is a case of patient who had severe mandibular prognthism with midface deformity. We performed modified LeFort III osteotomy for maxillary-malar advancement and simultaneous bilateral sagittal split ramus osteotomy for mandibular prognathism and autogenous iliac bone graft.

The trigeminal nerve, one of the cranial nerves, innervates the maxillofacial area and has three branches: the ophthalmic, maxillary, and mandibular nerves. Paresthesia, due to damages to the inferior alveolar nerve and mental nerve (branches of the mandibular nerve), is quite frequent in dental implants and third molar extractions. As medical disputes are increasing, it is necessary to formulate an objective and reasonable disability evaluation. When evaluating the frequent rate of impairment for inferior alveolar nerve damage, it may be reasonable to follow the criteria for the rate of maxillofacial impairment of the American Association of Oral and Maxillofacial Surgeons (AAOMS) - the most scientific and reputable criteria based on the American Medical Association (AMA). Therefore, the Committee of Guides for Maxillofacial Impairment Ratings, in the Korean Association of Oral and Maxillofacial Surgeons (KAOMS), is trying to suggest more reasonable and realistic guidelines for evaluating impairments by reviewing the current evaluation criteria and those of AMA and AAOMS.

After the Iraq war, the Korean government established an Iraq Peace and Reconstruction Division, 'Zaytun'. Zaytun division has been dispatched in northern Iraq, since August 3, 2004. As one of our missions, 'Zaytun Hospital' was built to support the demand for the insufficient medical facilities and supplies in Iraq, which was opened on November 27, 2004. Zaytun Hospital, equipped with modern operation room and general ward, has been composed of 12 clinical departments. Although we had many problems, such as difficulty of communication with Iraqis, connection with medical facilities of Iraq and risk of terrorism, we overcame these difficulties and were able to achieve our missions successfully. I wish that our special experience in Iraq are will be the guideline to other oral and maxillofacial surgeons, who want to help those individual in unfortunate areas such as Iraq.
