[Prosthetic rehabilitation in patients with malignant tumors of the soft palate. A clinical case report].

Soft palate neoplasms are relatively rare and their care requires not only an adequate surgical removal but also a post-treatment rehabilitation. In this article the authors after having considered the importance of the soft palate function on the individual's ability to shallow and speak, describe one case of squamous cell carcinoma of the soft palate and treated with surgery followed by prosthetic rehabilitation. Especially it is pointed out the utility of a palatal obturator in the care of deleterious esthetic and psychological aspect of the residual anatomical defect, considering the possibility of the re-establishment the integrity of the tissues and structures in the oral cavity by hand-made prosthesis more and more exact and functional.

[Clinical research of rehabilitating bilateral total maxillary defects with a new improved implants and magnetic attachments bar frameworks: report of 9 cases].

PURPOSE: The purpose of this study was to research the clinical effects of a new improved implant-magnetic attachment bar framework supported the total maxillary prosthesis. METHODS: Nine patients underwent tumor resection with defect of bilateral maxilla, and after at least 1 year,4 implants was inserted into their bilateral zygomatics in every patient. A kind of new improved bar framework were fabricated with implants tightly. Based on these bar framework ,total maxillary prostheses were completed finally. RESULTS: The new improved bar framework was utilized to support the prosthesis, it was observed that the prosthesis was more stable. All patients were satisfied with mastication, speech and appearance after wearing the prosthesis. The prosthesis demonstrated a significant improvement in function and esthetics. CONCLUSIONS: It is concluded that from the practical point of view,the prosthesis with new bar framework is superior to the previous one, and its clinical prosperity is wide. But further studies are necessary to evaluate its long term effects.

Sectional prosthesis for total maxillectomy patients: a clinical report.

Total maxillectomy is a relatively uncommon surgical procedure and usually results in a surgical and prosthetic reconstructive challenge. The goals of prosthetic treatment include separation of oral and nasal cavities, which allows for adequate speech and deglutition, along with restoration of esthetics. Treatment of a patient with total maxillectomy due to verrucous carcinoma was presented in this clinical report. Clinical and laboratory procedures of the prosthetic treatment were described. The sectional prosthesis retained by magnets eliminated long-term use of a nasogastric tube, rehabilitated the patient's speech, and restored proper midfacial esthetic contour.

Rehabilitation of a bilateral maxillectomy patient with a free fibula osteocutaneous flap.

Rehabilitation of patients who have undergone bilateral maxillectomy is difficult because of extensive loss of bone and soft tissue. In this clinical report, prosthodontic rehabilitation of oral function in a bilateral maxillecitomy patient combined with a new fibular osteocutaneous flap, which was designed to have two oronasal slits for the retention of an obturator prosthesis, was described. A 58-year-old man with a maxillary alveolar carcinoma underwent bilateral maxillectomy. The defect was reconstructed using a vascularized fibular bone wrapped circumferentially with a peroneal flap, which was fixed with miniplates between the right malar prominence and cut edge of the left zygoma remaining two slits anterior and posterior to the graft. Two and half weeks after the surgery, a delayed surgical obturator was delivered and an obturator prosthesis was delivered 6 weeks after the surgery. This obturator prosthesis could be extended into the slits to engage the tissue undercuts, and was stable during use. Mastication, deglutition, articulation and the mid-facial profile of the patient were rehabilitated. After installation of the obturator prosthesis, relining of the prosthesis base was carried out alongside the healing process of the graft, and adjustment of occlusions and high-pressure spots was carried out. No clinical disorders were observed either in the grafted tissue or the obturator prosthesis with a 3-year prognosis. Newly designing a fibular osteocutaneous flap combined with tissue-borne obturator prosthesis is one successful approach to the restoration of oral function, and increases the patient's quality of life after bilateral maxillectomy.

Effects of defect configuration, size, and remaining teeth on masticatory function in post-maxillectomy patients.

The aim of this study was to investigate the correlation between the masticatory function and the maxillary defect configuration, size, and remaining teeth in post-maxillectomy patients restored with an obturator prosthesis. Fifty consecutive post-maxillectomy patients (mean age 67.0) participated in this study. The subjects consisted of 26 dentate and 24 edentulous patients. Data were collected from the patients' clinical records, diagnostic casts, and a questionnaire on masticatory function to evaluate the defect configuration, size, and the masticatory function scores associated with wearing obturator prostheses. The defect size was evaluated by the ratio of defect area to the horizontal impression area. The defect configuration was assessed according to Aramany's classification and separated into unilateral and bilateral defects. The multiple regression analysis and the Mann-Whitney U-test (P<0.05) were used to assess statistical significance. The Spearman's correlation coefficient by rank test was also used to detect correlation. The following conclusions were made: (i) The presence of teeth in the maxillary dentition and the different type of the defect configuration had significant correlation with the masticatory function score (r=0.616). (ii) The masticatory function scores of the subjects differed significantly with the presence of teeth in the maxillary dentition and the different types of defect configurations (P=0.005, P=0.002, respectively). (iii) There was significant correlation between the masticatory function score and the size of the defect area in the edentulous group (r=-0.648, P=0.001). The presence of teeth, the size and configuration of the defect influenced the masticatory function of post-maxillectomy patients with obturator prostheses.

Maxillary definitive obturators: rationale of design.

Maxillary definitive obturators are usually fabricated for patients who have an acquired defect. The obturators help patients with speech, swallowing, mastication, esthetics and psychological well-being. The main goals in restoring a maxillary defect with a completely edentulous or partially dentate obturator are to provide adequate retention, increased stability and strong vertical support. This article addresses the step-by-step fabrication of a maxillary obturator that meets these goals.
