Obturator Prostheses (obturator + prosthesis)
Selected AbstractsEffects of defect configuration, size, and remaining teeth on masticatory function in post-maxillectomy patientsJOURNAL OF ORAL REHABILITATION, Issue 9 2005S. KOYAMA summary, 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.

Patil Abstract Aim: The aim of this article is to describe a technique to fabricate a spring retained surgical obturator prosthesis for rehabilitation of a patient with total maxillectomy. Material and Methods: The mandibular retention plate was fabricated with the help of hard, round, stainless steel orthodontic wires and heat-polymerizing acrylic resin. The 0.6 mm wire is manipulated to make Adams clasps on right and left mandibular first molars and 1 mm wire to make C clasps on right and left mandibular first premolars. A palatal shaped maxillary obturator plate was fabricated with acrylic resin. Two newly designed springs were fabricated with 0.6 mm orthodontic wire. Lower end of the springs were attached to the mandibular retention plate and upper ends were attached to the maxillary obturator plate. Results: When the appliance was placed in the mouth with the help of the mandibular retention plate, the maxillary obturator plate remains in a floating position in the mouth by spring-action on both sides. The springs used in the appliance were easy to fabricate and required less space in the buccal vestibules with minimum soft tissue irritation. Conclusion: This obturator develops the seal with the dorsum of the tongue during deglutition, thus helping the patient to take liquid food orally. It has proven to be the acceptable and comfortable treatment option for the patients with total maxillectomy, thereby, enhancing the quality of life during the initial healing period.
