PEEK Versus Metallic Attachment-retained Obturators

PEEK Versus Metallic Attachment-retained Obturators Regarding Patient Satisfaction: A Randomized Controlled Trial.

Patients' satisfaction evaluation and radiographic evaluation of the terminal abutments of attachment- retained maxillary obturators with metal framework versus milled PEEK framework in the management of maxillectomy cases.

Eighteen participants were randomly divided into three parallel groups (n=6). Participants of PEEK group received attachment-retained obturators with milled PEEK framework, metal group received an attachment-retained obturator with metallic framework and conventional group received conventional clasp-retained obturators with metallic framework (Control group). Evaluation included radiographic evaluation and patients' satisfaction where two scales were followed in this study, including "The Obturator Functioning Scale" and "The European Organization for Research and Treatment of Cancer Head and Neck 35" using one way ANOVA test.

Inclusion Criteria:

• patient underwent surgical removal of half of maxilla
• participants with a sufficient number of natural teeth(class I and \or class IV Aramany classification) not less than 5 teeth, mouth opening is not less than 25 mm, intact soft palate,

Exclusion Criteria:
