“…A fixed dental prosthesis failure maybe biological mechanical or aesthetic, it could cause discomfort caries, pulpal injury, periodontal breakdown, occlusal problems, tooth perforation, tooth fracture, loosening or dislodgement prosthetic fracture, occlusal wear or perforation [ 1 , 2 ]. In separate studies, caries and loss of retention were identified as the major events complicating FDP performance [ 3 ]. Faulty prosthesis can lead to harmful effects on the residual ridges; these serious effects are further compromised if the patient is systemically compromised [ 4 ].…”

A faulty prosthesis can cause damage more than relief. Poor people who cannot afford specialty treatment prefer to go to unregistered dental practitioners who are less expensive. Therefore, it is of interest to record the presence and type of old faulty prosthesis and its effect on surrounding structures. In this study 983 case sheets were reviewed from the record management system at the Saveetha Dental College, India using keyword search. Results show that 33% of faulty prosthesis leads to periodontally compromised abutments, 26% to decay of abutment tooth, 20% to gingival inflammation, 13% to denture stomatitis, 6.6% to non-vital abutment tooth. Faulty prosthesis damages abutment tooth and the surrounding structure of oral mucosa. Thus, damage to the periodontium in fixed prosthesis is common and prevalent. Hence, faulty dental prosthesis construction should be discouraged through awareness programme.

“…[ 2 ] A maxillofacial prosthesis intends to replace the missing oral or facial structures and its associated functions. [ 3 ] The prosthesis constructed to rehabilitate the maxillary defect is termed as an obturator. [ 1 ] The goals of prosthetic rehabilitation for maxillectomy patients include separation of the oral and nasal cavities to allow adequate deglutition and articulation, possible support of the orbital contents to prevent enophthalmos and diplopia, support of the soft tissues to restore the midfacial contour, and an acceptable esthetic result.…”

Prosthodontic management of palatal defect is fundamental to close patient's oronasal communication and improve masticatory function, phonetics, esthetics, and comfort. Maxillary defects are the direct consequence of the surgical treatment of malformations, neoplasms, or trauma. The primary goal of an obturator is to close palatal defects after maxillectomy and to improve speech and masticatory function. This clinical report describes the use of a flexible silicone obturator for the treatment of a 34-year-old patient with partial maxillectomy due to osteosarcoma of the maxilla. A conventional cast partial denture with a hollow bulb made in acrylic was given as a definitive obturator initially, which was not comfortable for the patient. Alternatively, a new technique of fabrication of obturator with silicone to close palatal defect was decided to establish an acceptable phonetics, comfort, speech, and function for the patient. This silicone obturator gets retention by “snug fit” from the defect site.
