| Abstract | ||||
| Objective: To evaluate the retention force between primary telescopic crowns milled from PEEK material and secondary telescopic crowns constructed from PEEK material with two different techniques (milled and pressed). Material and method: Primary and secondary copings (N= 28, n= 14 per group) were fabricated using Polyetheretherketon (PEEK) material. Primary telescopic crowns were milled using CAD/CAM technology while secondary copings were made with two different techniques: (group 1(PM): which milled from PEEK using CAD/CAM technology; while group 2 (PG): which fabricated from PEEK granules with pressing technique). The retention forces were analyzed using the universal testing machine where secondary copings were pulled off by an upper chain with a speed of 50 mm/min. Results: The milled PEEK secondary copings showed higher retention force values than the pressed ones. Conclusions: Different fabrication techniques of telescopic crowns influence the retention forces between the primary and secondary copings. Keywords: Implant retained mandibular overdenture, PEEK telescopic attachment, CAD/CAM technology. | ||||
