Embodiment Construction
[0017] The preparation method of the bioactive glass ceramic fiber / PEEK resin composite material artificial tooth of the present invention comprises the following steps:
[0018] (1) Preparation of hydroxycalcium phosphate crystal glass-ceramic fragments: 5-15 parts by weight of pure raw materials for chemical analysis SrO, 0.5-7 parts by weight of MgO, CaF 2 0.5-1 parts by weight, CaO 33-60 parts by weight, SiO 2 22 to 42 parts by weight, P 2 o 5 11-44 parts by weight, B 2 o 3 0.3-3 parts by weight, mixing all raw materials evenly, melting in a platinum crucible at 1400-1500 DEG C and then directly quenching water to obtain glass ceramic fragments with bioactive calcium hydroxyphosphate crystal main crystal phase.
[0019] In this step, adding a calcium (Ca) source increases biological activity, adding P 2 o 5 It is beneficial to the formation of glass ceramics. Adding fluorine (F) source can lower the melting temperature, adding silicon (Si) source can facilitate s...
