3D Virtual Object for Dental Bone Grafting Material Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental bone grafting procedures face inefficiencies in estimating and optimizing the amount of bone graft material needed, leading to potential waste and increased costs due to the reliance on pre-packaged vials or syringes without precise volume determination.
Innovation Solution
A method and device that utilize 3D imaging and virtual objects to dynamically estimate the geometric characteristics of bone graft material required, allowing practitioners to modify and optimize the use of bone graft material based on specific grafting needs, including the selection of standardized shapes and sizes, and generate 3D models for precise milling or 3D printing.

Engineering Contradiction Analysis
1Loss of substance
If pre-packaged vials or syringes of bone graft material are used without precise volume determination, then the procedure is simple and quick to prepare, but material waste increases and costs increase
Solution Approach 1:
The system performs preliminary 3D imaging and virtual planning of the bone grafting procedure before the actual surgery. The practitioner uses the 3D visualization tool to determine the precise volume and shape of bone graft material needed in advance, allowing for accurate material preparation and avoiding both waste and insufficient material during the procedure.
Solution Approach 2:
The patent replaces the traditional mechanical approach of estimating material needs with visual inspection and using pre-packaged volumes with the substitution of a digital 3D imaging and visualization system. This computational approach calculates the precise volume required based on the patient's anatomy and surgical plan, eliminating guesswork and material waste.
2Productivity
If 3D imaging and virtual object modification tools are used to estimate bone graft material characteristics, then material usage is optimized and waste is reduced, but the preparation time and device complexity increase
Solution Approach 1:
The system creates a virtual 3D copy of the patient's jawbone anatomy and the desired bone graft structure. This digital model allows the practitioner to visualize, measure, and modify the bone graft parameters without physical manipulation of actual materials. The virtual model serves as a precise template for determining the exact amount of material needed, improving efficiency while keeping preparation time reasonable through software-based planning.

AI summary
At least one embodiment of a method for dynamically assisting a practitioner in preparing a dental bone grafting operation, the method comprising:—providing an image representing a 3D volume of a portion of a jaw member where bone grafting is to be carried out;—adding to the image a representation of a 3D virtual object representing dental bone graft material;—estimating a value of a geometric characteristic relating to the bone graft material to be used, as a function of geometric characteristics of the represented 3D virtual object;—enabling a user to modify the representation of the 3D virtual object; and—upon modification of the representation of the 3D virtual object, updating the estimated value of the geometric characteristic, according to the modification of the representation of the 3D virtual object, the estimated value assisting the practitioner in determining the dental bone graft material needed.
