The invention relates to a manufacturing method of a comfortable full-mouth adsorption false tooth meeting an aesthetic function, and belongs to the field of false tooth manufacturing, wherein the method comprises the steps: drawing a central line, a mouth angle line and a lip base line on a temporary base plate loaded with a wax rim after occlusion mouth testing, and taking a bisector of jaw spacing after mouth testing; marking out an incision edge connecting line of the anterior incisor below the lip base line, and marking out a smile line above the lip base line; connecting the incisor edge line of the anterior incisor with the bisector of the jaw spacing after mouth testing to form a tooth arrangement plane curve on the same plane, wherein the mouth angle line is a positioning line between a three-tooth distal center and a four-tooth proximal center, the curve length from the mouth angle line to the central line is the basis for determining the width specification of the whole set of false tooth, the smile line is a base line for determining the tooth neck of the anterior incisor, and the distance from the smile line to the incisor edge connecting line of the anterior incisor is the basis for determining the height specification of the whole set of false tooth. Therefore, specification parameters of the whole set of false teeth and tooth arrangement positions of the false teeth can be determined, and the method is simple and easy to implement and has aesthetic characteristics on the premise of meeting false tooth functions.

The invention discloses a method for positioning and tracking outer contour feature points of key face organs and a device thereof, comprising the following steps: first, the positions of canthi points and angulus oris points on the face are obtained; the medial axis of the eyes and the mouth is identified based on the positions; the outer contour feature points of the eyes and eyebrows are identified on the medial axis of the eyes, and the outer contour feature points of the mouth are identified on the medial axis of the mouth. Consistent positioning and tracking of outer contour feature points of key face organs are conducted on such a basis. The technical proposal provided by the embodiment of the invention solves the problem of inaccurate positioning of outer contour feature points ofeyes, mouth and eyebrows when people makes various faces; based on the positioning of the feature points, the existing two-dimensional and three-dimensional face models can be real-time driven, and face expressions and motions such as frowning, blinking and mouth opening of people before a camera can be real-time simulated, thus creating various real and vivid face animations.

The invention discloses a facial mask containing active peptide components.
