RESUMEN
Chondrosarcoma (CS) is a malignant tumor of long and flat bone characterized by the formation of cartilage. Mesenchymal chondrosarcoma is a rare variety of chondrosarcoma .It is a biphasic tumor with areas of spindle cell mesenchyme along with chondroid differentiation in the connective tissue stroma. A 17 year old male presented to us as a painless mass in maxilla. Contrast enhanced computed tomography (CECT) showed a lytic expansile lesion in the right maxillary bone with foci of calcification within soft tissue lesion. Fine needle aspiration cytology (FNAC) and incisional biopsy was performed which confirmed the diagnosis of maxillary Mesenchymal chondrosarcoma .The patient underwent right subtotal maxillectomy with 2 cm margins. The review of literature shows that very lesser number of maxillary Mesenchymal chondrosarcoma cases were reported so far. Therefore an attempt is made to add this rare case of MC of maxillary alveolus in the Existing literature.
RESUMEN
During the lifetime of an individual there is a gradual wearing of the occlusal and axial surfaces of teeth resulting from mastication, habits and prolonged exposure to the hazards of some occupations. The loss of tooth structure not only affects the function and esthetics of an individual but it also results in discomfort due to pulp irritation, sensitivity, inability to eat hard food and thus can affect digestion. However with the advancements in material science and modern treatment techniques dental practitioners are more than equipped to manage this loss of tooth structure restoring both esthetic as well as functional harmony of the stomatognathic system. This case report describes the prosthetic management of a patient with severely worn down dentition using Hobo's twin stage technique to produce definite anterior guidance and posterior dis-occlusion
