Modular Jaw Adapter and Drilling Template for Dental Implants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantation aid arrangements for drilling jaw implants are complex, imprecise, and cumbersome, making the spatially exact drilling of implant holes in patients' jaws challenging.
Innovation Solution
A modular implantation aid arrangement comprising a jaw adapter with a radiologically non-visible individual molded part and a separate drilling template, featuring a coupling plug and 3D markers for precise alignment, allowing for reproducible coupling and spatially unambiguous positioning, eliminating the need for a pilot hole in the jaw adapter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a modular implantation aid arrangement with separate jaw adapter and drilling template is used, then ease of operation and precision are improved, but device complexity increases
Solution Approach 1:
The implantation aid arrangement is divided into separate functional modules: a jaw adapter that interfaces with the patient's jaw and a drilling template that guides the drilling operation. This segmentation allows each component to be optimized independently for its specific function while maintaining overall system precision through standardized coupling mechanisms.
2Ease of operation
If a pilot hole is drilled in the jaw adapter, then ease of operation is improved, but device complexity and manufacturing steps increase
Solution Approach 1:
Instead of requiring a pilot hole to be drilled in the jaw adapter during the implantation procedure, the drilling template is designed to directly guide the final implant hole drilling operation. This eliminates the preliminary pilot hole step while maintaining ease of operation through the template's guide holes that provide direct drilling paths.
3Measurement precision
If radiologically visible markers are added to the jaw adapter, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Radiologically visible markers (such as metal spheres or high-density material indicators) are added only at specific critical locations on the jaw adapter where precise positioning is required for radiological imaging and planning. This localized addition provides necessary measurement precision without requiring complex modifications to the entire jaw adapter structure.

AI summary
The assembly (10) has jaw adapter (22) having molding (24) attached to patient jaw (12), to which coupling plug (28) is connected. The jaw adapter has three-dimensional marker (36) that establishes spatial relationship between jaw and adapter. The adapter is aligned with bore to be implant (51-53) provided with access opening (40,46). The adapter is provided with template (34) having guide bore (41-43) to drill an implant bore into jaw, and a coupling bush (30) that is connected to coupling plug with respect to clutch assembly, such that access opening (40) is closed. : An independent claim is included for method for drilling implant bore in patient jaw. USE : Implantation assistance assembly for implanting jaw implant for fixing dental prosthesis to patient's jaw. ADVANTAGE : The assembly can be handled easily. The template can be produced easily. The size of assembly is reduced. The dental prosthesis is radiographically visible and is used as planning tool for virtual design and construction of the denture portion. The mechanical stability of jaw adapter is improved. The quality, accuracy and resolution of Kiefer image can be improved.
