The invention discloses a digital periodontal
soft tissue prognosis prediction method, an aesthetic design method and a
system, and the method comprises the steps: obtaining original
CBCT image data, carrying out the
data processing, obtaining a three-dimensional
data model, carrying out the recognition, segmentation and post-
processing of a
hard tissue anatomical structure in the three-dimensional
data model, and obtaining the three-dimensional digital model data of a
tooth root and upper and lower jawbones; the method comprises the following steps: acquiring original scanning image data, converting the acquired original scanning image data into
point cloud data, and performing optimization
processing and
feature extraction on the
point cloud data to obtain a dental crown and gingival
soft tissue three-dimensional digital model; registering and fusing the three-dimensional digital models of the
tooth root and the upper and lower jawbone as well as the dental crown and the gingival
soft tissue to obtain an initial three-dimensional digital
oral cavity anatomical model, carrying out geometric operation, and carrying out stretching treatment by utilizing a Laplace surface editing
algorithm to obtain a three-dimensional digital
oral cavity model; and performing visual display and
interactive analysis on the initial three-dimensional digital oral anatomical model and the three-dimensional digital oral model, and predicting a prognosis effect.
