Abstract

The invention provides a gingival excision guide plate manufacturing method, wherein the method comprises the steps: acquiring three-dimensional image data of an oral cavity of a patient, and generating a virtual oral cavity model according to the three-dimensional image data of the oral cavity; generating a guide plate model according to the virtual oral cavity model; adjusting the relative position between the guide plate model and the virtual oral cavity model, and making the guide plate model wrapping the virtual oral cavity model; generating a curve model of gingiva needing to repair according to a diagnostic wax model, and attaching the curve model to the corresponding position of the virtual oral cavity model; subtracting the curve model from the guide plate model, to obtain a guideplate model with the gingival repair curve; according to the guide plate model with the gingival repair curve, preparing the gingival excision guide plate. The gingival excision guide plate manufacturing method has the beneficial effects that provided is the gingival excision guide plate manufacturing method, the gingival excision guide plate manufactured by the method can enable doctors to quickly position the position where the gingiva needs to be excised and operate on patients along the guide plate, thereby ensuring the gingival excision effect and reducing the risk of overtreatment.

Description

technical field [0001] The invention relates to the technical field of dental treatment instruments, in particular to a method for making a gingival excision guide plate and the gingival excision guide plate. Background technique [0002] Gingivectomy refers to the surgical removal of hypertrophic gingival tissue or medium-depth periodontal pockets in certain parts of the posterior teeth to reconstruct the physiological shape of the gingiva and the normal gingival sulcus. [0003] At present, gingivectomy surgery is not assisted by effective instruments, relying solely on the doctor's sensory experience to determine the position of the knife by manual visual inspection, and performing gingival resection in a "blind cut" method, errors may occur, and excessive resection may lead to high or low gingiva The uneven problem, which is not aesthetically pleasing, requires secondary resection, causing pain to the patient. Contents of the invention [0004] The technical problem t...
