Restoration of a long span partially edentulous maxilla with tooth supported prosthesis is challenging because of inherent anatomic limitations and unfavourable biomechanics present after the loss of teeth. A tooth supported fixed-removable prosthesis is a treatment option for restoration of such long span partially edentulous maxillary arches. This prosthesis meets the requirements for esthetics, phonetics, comfort, and hygiene, as well as favourable biomechanical stress distribution to the remaining natural tooth abutments. This article presents a procedure for fabrication of a fixed-removable prosthesis that has cement-retained custom cast bar metal substructure and a ball attachment retained removable superstructure prosthesis.
Giant cell tumor (GCT) of bone is a distinctive neoplasm characterized by abundance of multinucleated giant cells scattered throughout the stroma of mononuclear cells. Its importance lies in recognizing and differentiating the characteristic histology, which at times may mimic several other bone tumors and endocrine disorders ranging from locally aggressive giant cell granulomas to hyperparathyroidism to malignant tumors. The jaw bones account for less than 1% of the lesion. Ina literature search, we found only five cases of GCT of jaw bones based on the new criteria. We present a rare case of GCT of the mandible which occurred in a 12-year-old female.
The science and art employed in the profession of dentistry can play an important role in the fabrication of an orbital prosthesis. Anophthalmia (the loss of an eye) not only impairs patient's vision but also create a noticeable deformity on facial appearance and esthetics. The condition is a psychological distress for the patient interrupting his routine work. A prosthodontist as an integral member of the craniofacial rehabilitation team can help raise the spirits and ease the mind of the affected. Mutilation of a portion of a face can cause a heavy impact on the self image and personality of an individual. Acceptable cosmetic results usually can be obtained with a orbital prosthesis. This paper describes prosthetic rehabilitation of a 30-year-old female patient having a left and right ocular defect. A technique to modify stock eye with heat polymerizing polymethyl methacrylate is illustrated. The resultant prosthesis was structurally durable and esthetically acceptable with satisfactory retention. The importance of meticulous treatment planning to tackle the challenges faced in fabricating an ocular prosthesis is explained with the relevant literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
