Drill-Less Dental Implant Insertion for Jaw Bone Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implantation methods require drilling, which can cause loss of jaw bone tissue, difficulty in controlling drilling direction, and are unsuitable for narrow jaw bones.
Innovation Solution
A drill-less dental implant with a sharp tip and spiral protrusion is used, allowing rotational screwing and linear insertion without pre-drilling, enabling adjustment of insertion direction and compression of jaw bone tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If drilling is performed to prepare a hole for implant insertion, then the implant can be inserted into the jaw bone, but jaw bone tissue is lost and the amount of tissue remaining to hold the implant is reduced
Solution Approach 1:
The patent extracts the harmful drilling process from the implantation sequence. Instead of drilling a hole before insertion, the implant is designed with a sharp tip that directly penetrates the bone without requiring pre-drilling, thereby eliminating tissue loss while maintaining insertion capability
Solution Approach 2:
The patent inverts the traditional sequence by making the implant itself the penetrating tool rather than using a separate drill. The sharp tip of the implant performs the penetration function that would otherwise require a drilling operation, reversing the conventional approach of preparing the site before insertion
2Ease of manufacture
If drilling is performed to prepare a hole for implant insertion, then the implant can be inserted, but the direction of drilling cannot be controlled
Solution Approach 1:
The patent enables dynamic adjustment of insertion direction during the implantation process. The surgeon can modify the angle and trajectory of implant insertion in real-time based on anatomical conditions, whereas traditional drilling requires pre-established directional control that cannot be adjusted once the hole is drilled
3Ease of manufacture
If drilling is performed to prepare a hole for implant insertion, then the implant can be inserted, but the process is unsuitable for narrow jaw bone tissue
Solution Approach 1:
The patent designs the implant with a sharp, localized tip that concentrates penetration force on a small area of bone. This local quality allows the implant to penetrate narrow jaw bone tissue effectively without requiring the larger clearance space needed for traditional drilling operations
Applied Scientific Principles
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 preserves jaw bone tissue, facilitates insertion in narrow areas, and enhances stability by compressing the bone, eliminating the need for drilling and its associated complications.
Implementation Method 1
the sharp tip linearly penetrates the jaw bone
Implementation Method 2
enhances stability by compressing the bone

AI summary
A method for implanting a drill-less dental implant into a jaw bone comprises implanting a drill-less dental implant that comprises: a screw thread comprising a core having a surface and a sharp tip and a spiral protrusion extending from the surface, wherein when the screw thread is rotationally screwed into the jaw bone, the sharp tip linearly penetrates the jaw bone; and a prosthesis support attached to an upper edge of the screw thread and configured to support a dental prosthesis. The method for implanting the drill-less dental implant comprises: positioning the drill-less dental implant on top of a desired implantation site in the jaw bone; and rotationally screwing while linearly inserting, the drill-less dental implant into the jaw bone until the drill-less dental implant is inserted into the jaw bone in a desired depth. Additional embodiments of the method are disclosed herein.
