Distant metastasis of follicular thyroid carcinoma to the mandible: a rare case report

Treatment of metastatic carcinoma of the oral cavity can be a challenge due to its rarity. The current case report details metastatic carcinoma of the mandible originating from follicular thyroid carcinoma, which is the second most prevalent tumor of the thyroid. As the mandibular lesion developed, the primary thyroid lesion of thyroid. Here, we report a case of metastatic carcinoma of the mandible in a 67-year-old female that was treated with partial mandibulectomy and fibular free flap.

Maxillofacial rehabilitation of hemi-maxillectomy patient using a closed hollow bulb obturator fabricated by one-step polymerization technique: a clinical report / 대한치과보철학회지

The maxillary defects lead to anatomical and functional deformity of the maxillofacial region. As far as functions are concerned, such defects can produce difficulty in speech, mastication, and deglutition. Obturator prostheses play a very important role in functional recovery for post-maxillectomy patients. To achieve rigidity of the obturator, appropriate retention should be given, and the weight of the prosthesis be reduced. There are two types of hollow bulb obturator: open and closed. A closed type has many advantages. Nevertheless, some problems, including complexity of fabrication and water leakage into the bulb, have the closed hollow obturator not be widely used. The one-step polymerization technique described in this case overcomes the shortcomings by easily constructing a small hollow bulb with two thermoplastic resin sheets.

Full-mouth rehabilitation with CAD/CAM monolithic zirconia in dentinogenesis imperfecta: a case report / 대한치과보철학회지

Dentinogenesis Imperfecta, with a high incidence rate of 1 : 6 - 8000, is inherited by autosomal dominant genetic transmission. This dental disorder causes discoloration of the teeth and the enamel and dentin show hypoplastic or hypocalcified defects which lead to frequent fractures and rapid attrition. Therefore, timely treatment is necessary for the preservation of the remaining teeth. In this particular case, a 19-year-old patient suffering from Type 1 dentinogenesis imperfecta showed signs of brownish hued teeth with multiple fractures, a loss of vertical dimension, excessive interdental space in the maxillary anterior teeth, and a lack of 5 posterior teeth. To improve the esthetic appearance of the anterior teeth, the vertical dimension was increased. Resin caps were used to alleviate the difficulty of taking an impression of multiple teeth at once. Monolithic zirconia materials used in this case showed high fracture strength and the ability to mask the discoloration of the teeth and therefore, functionally and esthetically favorable results were achieved.
