The invention relates to the technical field of tooth
orthodontics, in particular to a method for generating a personalized
silica gel tooth socket digital model, which comprises the following steps: inputting data of a tooth model, a gingival model and a tooth slit
undercut model, generating upper and lower edge lines based on
interaction point partition interpolation, dividing the outer side surface of a tooth socket into a lip side area, a
tail end area and a tongue side area according to the edge lines, and generating a personalized
silica gel tooth socket digital model. An outer side
mesh model is automatically constructed by adopting different parameterization strategies,
oral cavity entity models are firstly combined through Boolean operation, then a closed outer side shell is subtracted from the
oral cavity entity models, and an inner side
mesh model is accurately generated; and finally, carrying out constrained fairing, and locking a contact area with the teeth while
smoothing the model so as to ensure the adaptability. According to the method, the change from selection
adaptation to calculation generation is realized, the modeling logic of
dissection function partition is constructed, the precise inner side face generation technology of Boolean forming from outside to inside is invented, and full-automatic and personalized generation of the tooth socket digital model is realized.
