Abstract
Embodiments may provide a method for measuring a site of bone graft and an amount of bone graft around a virtual fixture. To this end, according to embodiments, a type of bone defect may be determined based on bone density information of an alveolar bone around a virtual fixture, and the site of bone graft and the amount of bone graft may be determined according to the determined type of bone defect. According to embodiments, there is an advantageous effect that accurate information can be provided to a user to enable precise grafting during implant surgery.
Claims14
A method for determining an amount of bone graft, the method comprising:
- placing a virtual fixture in a dental image;
- based on a bone density of an alveolar bone around the virtual fixture, detecting a boundary area of the alveolar bone;
- measuring a distribution of the bone density of the alveolar bone around the virtual fixture from at least one cross-sectional image of cross-sectional images in a plurality of directions and, based on the distribution of the bone density of the alveolar bone and the boundary area of the alveolar bone, determining a type of bone defect of the alveolar bone;
- and
- based on the type of bone defect, determining an amount of bone to be grafted onto a bone defect area.
An apparatus for determining an amount of bone graft, the apparatus comprising:
- a memory configured to store a simulation control program for determining the amount of bone graft;
- and
- a processor configured to run the simulation control program stored in the memory,
- wherein the processor places a virtual fixture in a dental image, based on a bone density of an alveolar bone around the virtual fixture, detects a boundary area of the alveolar bone, measures a distribution of the bone density of the alveolar bone around the virtual fixture from at least one cross-sectional image of cross-sectional images in a plurality of directions, based on the distribution of the bone density of the alveolar bone and the boundary area of the alveolar bone, determines a type of bone defect of the alveolar bone, and based on the type of bone defect, determines the amount of bone graft.
