Dental implantation assessment method for implant dentistry

A dental implantation assessment method for implant dentistry, comprising:

• a digital model creation step, in which a computed tomography (CT) device is used to scan a patient’s oral areas to construct a digital oral model and a model database, the digital oral model includes a plurality of tooth models and an alveolar bone model, the model database stores a plurality of position data and a plurality of density data as a healthy status table, and the position data and the density data match each position of the alveolar bone model;
• a position determination step, in which an electronic device receives the digital oral model to display the tooth models and the alveolar bone model, the electronic device selects an objective tooth of the tooth models to construct a reference line matching a centric occlusion of the objective tooth, and constructs an implantation space model based on the reference line to encircle the alveolar bone model;
• a space dividing step, in which the electronic device divides the implantation space model into a plurality of layers, the layers include a center area and a plurality of analyzing areas located immediately around the center area, and the analyzing areas are divided into a plurality of assessment zones;
• an implantation simulation step, in which the electronic device selects a digital dental implant to place in the implantation space model, such that the digital dental implant overlaps the center area of layers, and one of the assessment zones adjacent to an outer peripheral surface of the digital dental implant is defined as a selected zone;
• and
• a result generation step, in which the electronic device receives a plurality of objective density data matching the selected zone of the analyzing areas from the model database, and compares each objective density data with a density threshold value to determine an assessment value of the selected zone;
• the electronic device compares a sum of the assessment values with a threshold value to determine an object type of the digital dental implant, the digital dental implant being determined as a suitable object allowed for use in immediate implant placement when the sum is larger than the threshold value;
• and the digital dental implant being determined as an unsuitable object failing to provide stable and firm fixing ability when the sum is smaller than the threshold value.
