概要

of polyetheretherketone (PEEK), a high-performance thermoplastic polymer, to restorative dentistry, as a candidate for replacing
metallic components in dental prosthesis. The mechanical
properties of PEEK do not change during the sterilization process
and its elastic modulus is similar to those of human bone, enamel,
and dentin, suggesting it to be a suitable restorative material. PEEK
features stable chemical properties, and is biocompatible, wearresistant, stable at high temperatures, insoluble in water. This
material also presents low reactivity with other materials, is nonallergic, and has lower plaque afﬁnity than other materials such as
metals and resins. Furthermore, PEEK can be processed using
computer-aided design and computer-aided manufacturing (CAD/
CAM), rendering it easily reproducible in the event of failure, and
easily relined in the case of resorption [9–16].
The combination of these unique mechanical and physical
properties renders PEEK a promising material for replacing metal
frameworks. To date, there have been few clinical studies that discuss
the application of PEEK as a framework material for RPDs [17,18];
nevertheless, according to its superior ﬂexible properties, obtaining
the necessary retentive force and fatigue resistance will be key
challenges in the development of PEEK RPD clasps [19,20]. Therefore,
the objective of this study is to optimize PEEK clasp design in order to
provide the mechanical properties required by RPDs.
2. Materials and methods
2.1. Generating three-dimensional models
Three-dimensional (3D) models with clasp arms in the form of a
rod-shape were designed by SolidWorks 2013 (Dassault Systèmes
SolidWorks, Waltham, MA, USA). The 3D models were 15 mm in
length and the loading point was set at 3 mm from the tip (Fig. 1).
These models were classiﬁed into four groups based on thickness/
width ratios (Tb/Wb), and each group was then divided into three
subgroups according to the base width. ...
