Clinical effect of prosthesis on type Ⅴ maxillary defects

To investigate the clinical efficacy of prosthesis retained by metal clasp and flexible clasp in the repair of type Ⅴ maxillary defects after tumor resection.

23 maxillary tumor surgical patients were selected in this study and restored with maxillofacial prosthesis. Total 24 prosthesis combined with metal clasp and flexible dentures were followed up for half a year to 2 years.

After the application of prosthesis, better maxillofacial appearances are presented in all of the patients, Watian drinking water tests are improved to grade Ⅰ or Ⅱ from grade Ⅳ or Ⅴ in 21 patients, there was significant difference (P < 0.05); Soft diet can be masticated on affected side in 15 patients; The mean speech intelligibility score with and without prosthesis were (83.2 ± 7.3)% and (36.6 ± 5.6)%, there was significant difference (P < 0.05); Favorable hygienic situations of oral cavity and prosthesis are maintained in 18 patients.

Prosthesis combined with metal clasp and flexible denture performed favorable clinical efficacy and contributed to improve the living quality and mental health after tumor resection.
