Combination of ADLC-coated abutment and PEEK ­retention inserts: A reliable connection that endures

Retention loss after 10’000 cycles of the straight abutment ­performed in phosphate buffered saline (pH 7.4) at room ­temperature. Data represents difference between the basal (100 cycles) and final (10’000 cycles) ­measurements (Fmax) presented as percentage change (source: ­Straumann, data on file).
