Application of obturator to treat velopharyngeal incompetence.
OBJECTIVE: To evaluate the effect of a system of velopharyngeal incompetence (VPI) management after the application of obturator. METHODS: Using nasopharyngofiberoscope (NPF) and a computer analysis system, we quantitatively analyzed the improved state of velopharyngeal incompetence in 100 patients with unilateral and/or bilateral cleft palate. RESULTS: The velopharyngeal closure (VPC) can be greatly improved by using a temporary oral prosthesis (obturator) and speech training. An objective quantitative standard was established to evaluate the change of velopharyngeal closure of cleft palate patients after surgery and conservative treatment. CONCLUSIONS: The method used is more succinct, accurate and practical than previous methods. In order to reflect the state of velopharyngeal incompetence, the concept of improvement rate of velopharyngeal incompetence (IRVPI) is put forward. (+info)
Application of a temporary palatal prosthesis in a puppy suffering from cleft palate.
A 3-month-old Schnauzer was presented with congenital defects of the secondary palate. On the clinical examination, coughing, sneezing, drainage of nasal discharge from the external nares and poor growth were found. Vital signs and results of blood examination were within normal ranges. Thoracic radiography revealed mild pneumonia in the right lung lobes. In a puppy suffering from cleft palates, a palatal prosthesis was applied to the hard palate in order to protect the surgical wound, because a routine surgery was not successful. A palatal prosthesis was applied and held in place using the instant glue and plastic bands to protect the surgical wound following the third repeated surgery. Although a small oronasal fistula still remained, there was no functional defect. This prosthesis was easy to apply and helpful to protect the surgical wound. In addition, this implant could be placed or adjusted without or sedation/anesthesia. (+info)
Prosthetic rehabilitation of a completely edentulous patient with palatal insufficiency.
This article presents a case report of a completely edentulous patient with palatal insufficiency successfully rehabilitated with closed hollow bulb obturator prosthesis and also describes a simple technique for fabricating a two-piece hollow bulb obturator that allows for control of the bulb's wall thickness and weight of the prosthesis.

Obturator prostheses following palatal resection: clinical cases.
Malignant tumours of the upper gum and hard palate account for 1-5% of malignant neoplasms of the oral cavity; two thirds of the lesions which involve these areas are squamous cell carcinomas. Most of these carcinomas are diagnosed late, when they invade the underlying bone. The procedures of choice for removal are: alveolectomy, palatectomy, maxillectomy, which may be total or partial. Surgical reconstruction of the defect may be carried out using a wide range of microvascularized flaps: osteomuscolocutaneous of the internal iliac crest, an osteocutaneous flap of the fibula or scapula, fascia, or osteocutaneous radial flap, or a pedicled flap of temporal muscle. These flaps are supported by single or multiple obturator prostheses. Rehabilitation via palatal obturators is preferred in patients with a poor prognosis or in weak condition. Rehabilitation aims to: restore the separation between the oral and nasal cavities, enable the patient to swallow, maintain or provide mastication, sufficient occlusion and mandibular support, support the soft facial tissues, re-establish speech and restore an aesthetically pleasing smile. Hence, it is crucial to work in close cooperation with the staff who makes the prosthesis and who evaluates the case when the surgery is planned and obtains the necessary gnatological, anatomical and functional information. 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. In this regard, the Odonto-prostheses Service of the Stomatological Clinic does not follow a rigid protocol but materials and techniques are selected on a personal basis, according to the features of each individual clinical case. Mobile rehabilitative systems are the systems of choice, both of which related to the traditional concepts of retention and stability and systems of self-stabilizing prostheses according to J. Dichamp, albeit modified in materials, limiting, when possible the use of prostheses which are fixed on natural teeth, on appliances or combined. (+info)
