COMPARISON OF RETENTIVE FORCES OF CLASPS MADE FROM THERMOPLASTIC RESIN AND CONVENTIONAL COBALT CHROMIUM (IN VITRO STUDY)

Noha Y. Abd-Elrahman, Mohamed S Badawy And Nancy N. Elsherbini,

ABSTRACT
In Vitro Study Was Conducted To Compare The Retentive Values Of Conventional Co-Cr (Aker?s) Clasps With Esthetic Clasp Constructed From PEEK Material, For This Purpose A Maxillary Experimental Model With Ideal Anatomical Features Was Selected. The Model Has Missing First Permanent Molar, Two Prostheses Were Constructed, Then The Retentive Values Were Measured Using Force Gauge.

Results: The Conventional Co-Cr Clasps Showed Statistically Significant Higher Retentive Values Than PEEK Clasps.
