The invention relates to a customized
abutment assembly and a preparation method thereof. The
assembly comprises an
abutment body, a fixed bolt connected between an
implant body and the
abutment body and an anti-loose pad, wherein the abutment body comprises a dental crown connecting section, a gum penetrating section and an
implant body connecting section, and a stepped bore is formed in the abutment body; the abutment
angle alpha and abutment shape of the abutment body are formed according to angles and shapes of a
patient affected tooth and the
implant body, so as to adapt to the angles and shapes of the
patient affected tooth and the implant to obtain the customized abutment; the abutment
angle alpha is the included angle between the center line of the dental crown connecting section and the center line of the implant body connecting section. The abutment
assembly is formed by means of 3D (three-dimensional) scanning, CAD (
computer aided design) modeling, 3D printing and
thermal treatment, can sufficiently meet the customized requirements of different patients, and is advantageous to improve the aesthetic effect of teeth and better accords with physiological functions of teeth. Moreover, hospitals need not store massive products for clinical option, and the medical cost is furthest saved.
