The journal of advanced prosthodontics 411 prosthetic reconstruction with an obturator using swing-lock attachment for a patient underwent maxillectomy: a clinical report. Obturator prostheses fabricated for patients with large palatal defects consistently restore speech and swallowing to normal levels, but lack sufficient stability, retention and support to restore mastication to presurgical levels.
Rests and vertical guide planes may help in providing support to obturator prosthesis in partially dentate individuals4 maximum extension onto the residual palate, alveolar processes and contact of obturator with pterygoid plate, temporal bone, nasal septum, vomer, floor of the orbit, or any other osseus structure within the defect may prove. Maxillofacial prosthetics - restoration of soft palate defects a properly designed and extended obturator prosthesis for a soft palate defect should provide the patient with perfect speech if a segment of the velopharyngeal musculature remains. Thereafter, during the surgical stage, for the immediate obturators, or in the successive days, for the temporary obturators, work is devoted to making the prostheses.

Cheek prosthesis with palatal abjuratory & guiding plate for cancer patient. Abstract surgical treatment for palate cancers can result in oral-nasal/sinus communication, which impairs the swallowing, speech and chewing ability of patients with reflux of ingested food into the nasal cavity, reducing their quality of life. A palatal obturator is a prosthesis that totally occludes an opening such as an oronasal fistula (in the roof of the mouth) they are similar to dental retainers, but without the front wire. A soft palate obturator (also known as a speech and feeding aid/device) replaces the missing piece(s) of muscle(s) and fills the hole a palatal lift prosthesis aids in repositioning the soft palate in the raised closed position.

Palatal obturator functional, aesthetic and orthopedic prostheses for patients who have partial o total loss of palatal tissues, as a result of cancer or injuries the prosthesis will restore or improve aesthetics and many lost functions as eating, swallowing, breathing and communicating. The prosthetic rehabilitation involved the emplacement of a complete adapted prosthesis, using a palatal obturator, with a view to sealing the defect and allowing the patient to acquire better speech quality, and improve.
A palatal lift prosthesis is a prosthesis that addresses a condition referred to as palatopharyngeal incompetencepalatopharyngeal incompetence broadly refers to a muscular inability to sufficiently close the port between the nasopharynx and oropharynx during speech and/or swallowing. Precision attachment retained palatal obturator in a completely edentulous patient: a case report k aravind 1 and ashish r jain 2 1 department of prosthodontics, saveetha dental college and hospitals,saveetha university, chennai, india 2 department of prosthodontics, saveetha dental college and hospitals, saveetha university, chennai, india. Palatal defect is a common maxillofacial defect after maxillectomy that can be repaired by obturator prostheses, which can effectively improve patients' speech however, comprehensive evaluation methods for speech recovery are still controversial and remain undefined a prospective cohort study on 34 patients with palatal defect and 34 healthy controls was performed.
Surgical treatment for palate cancers can result in oral-nasal/sinus communication, which impairs the swallowing, speech and chewing ability of patients with reflux of ingested food into the nasal. An obturator is an oral prosthesis we make a mold of your mouth and then construct the device out of plastic or metal an obturator can also be used if the opening in the palate recurs after surgery or, in certain cases, as an alternative to surgery or as a temporary measure until surgery is appropriate. Reconstruction with prosthesis new app may help kids with cleft palate speak easier - wgn medical watch - duration: 3:17 shriners hospitals for children — chicago 12,087 views. A palatal obturator is a prosthesis that totally occludes an opening such as an oronasal fistula (in the roof of the mouth )they are similar to dental retainers , but without the front wirepalatal obturators are typically short-term prosthetics used to close defects of the hard/soft palate that may affect speech production or cause nasal regurgitation during feeding.
Palatal obturator is the only substitute which covers the defect and contributes to normal speech production it eliminates hypernasality and improves the communication an obturator prosthesis for an edentulous patient becomes more critical in terms of its movements as there is no mechanical retention available. A palatal lift prosthesis is used to treat this condition it lifts the soft palate superiorly and laterally to optimized its relationship to the muscles of the pharynx (throat) during the functions of speech and swallowing. Protocols for prosthetic obturation versus microvascular reconstruction have been established and used effectively in tertiary institutions for patients with such large defects read more. A palatal obturator may be used to compensate for hypernasalityand to aid in speech therapy targeting correction ofcompensatory articulation caused by the cleft palatespeech bulbs and palatal lifts aid in velopharyngeal closure and donot obturate a fistulaa speech bulb, yet another type of prosthetic device oftenconfused with a palatal.
