Autogenous Tooth Root Alveolar Bone Graft Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone grafts for alveolar bone reinforcement, such as synthetic and xeno grafts, face limitations including immune rejection, low bone regeneration rates, and the need for additional operations, while autogenous bone grafts are limited in quantity and require complex processing.
Innovation Solution
A method to process an extracted patient's own tooth into a block film, block plate, or tooth root form alveolar bone graft by separating the tooth into a crown and root, trimming and cleaning, followed by dewatering, degreasing, decalcifying, and freeze-drying, and sterilizing to create a graft that can be implanted to reinforce alveolar bone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bone grafts (synthetic, xeno, allograft) are used to preserve and reinforce alveolar bone, then implant operation can be performed, but immune rejection occurs and complicated processing is required
Solution Approach 1:
The patient's own tooth is used as the graft material source, making the immune system recognize the material as self and eliminating rejection responses. The tooth structure itself serves as both the implant source and the graft material, requiring no complex immune-matching processing
Solution Approach 2:
Instead of discarding extracted teeth as waste, the invention recovers and reuses them as valuable bone graft material. The tooth structure is processed and reused within the same patient, eliminating the need for additional graft sources and complex processing
2Productivity
If conventional artificial bone graft structures are used, then implant operation can be performed, but bone regeneration rate is low due to absence of bone morphogenetic proteins
Solution Approach 1:
The invention changes the material composition parameter by using natural tooth structure containing endogenous bone morphogenetic proteins, growth factors, and osteogenic cells. This biological composition parameter enables active bone regeneration rather than passive structural support
Solution Approach 2:
The tooth structure serves as a composite material containing multiple bioactive components including dentin, cementum, periodontal ligament cells, bone morphogenetic proteins, and growth factors, all working together to promote bone regeneration
3Reliability
If autogenous bone is used for bone graft, then immune compatibility is achieved, but additional operation is needed and amount of raw material is limited
Solution Approach 1:
The invention merges two separate procedures (tooth extraction and bone grafting) into one unified treatment. The extracted tooth is immediately processed and used as the graft material for the same patient's alveolar bone defect, eliminating the need for a second surgical site and additional operation
Solution Approach 2:
The extracted tooth serves multiple functions: it is both the source of the problem (requiring extraction) and the solution (providing graft material). This multi-functionality eliminates the need for separate graft material sourcing and reduces the total number of surgical interventions
4Quantity of substance
If extracted tooth is processed into alveolar bone graft, then availability of bone transplantation material increases and immune rejection is prevented, but complex processing steps are required
Solution Approach 1:
The tooth is segmented into functional components (crown, root, periodontal ligament) and processed accordingly. Different segments are treated differently to maximize their graft value while simplifying the overall processing workflow through systematic division of labor

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method increases the availability of bone transplantation material, prevents immune rejection, and allows for stable and economic implant operations without additional surgeries, effectively addressing the limitations of existing bone grafts by utilizing the patient's own tooth as a graft with similar properties to autogenous bone.

AI summary
The present invention discloses an alveolar bone graft, a processing method thereof, and a method of treatment using the same. The processing method of the present invention comprises the steps of: (a) separating the tooth gathered from a patient into a crown and a root; (b) removing soft tissues and enamels within neurons of the crown and the root; (c) washing the crown and the root taken in step (b); (d) forming a number of holes in the washed crown and the root; (e) dewatering, degreasing and decalcifying the crown and the root having a number of holes; and (f) freeze-drying the crown and the root. The present invention allows the safety of an implant operation to be improved; and a metastasis of infectious diseases of allograft, xeno (animal) graft to be prevented by using the patient's own tooth. Also, the present invention allows an autogenous bone graft to be possible without additional operations.
