Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental prosthesis systems face challenges in achieving precise implant insertion in the jaw without an ingrowth period, requiring high precision and accuracy in implant placement and prosthesis design for immediate attachment, which complicates the process and prolongs preparation time.
Innovation Solution
A method involving a digital model of the jaw and soft tissue connection, a provisional removable dental prosthesis, a support piece, and a drilling template for accurate implant placement, allowing for immediate attachment of the permanent prosthesis after precise implant insertion with a tolerance of less than 35 µm, utilizing 3D imaging and rapid prototyping techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If implants are inserted immediately without an ingrowth period, then treatment time is reduced, but implant placement precision requirements increase significantly
Solution Approach 1:
The patent applies preliminary action by creating a provisional removable prosthesis before implant insertion that serves as a guide for subsequent permanent prosthesis placement. The provisional prosthesis is positioned and fixed in the oral cavity, and its position is recorded through tomographic imaging. This pre-positioning allows the permanent prosthesis to be manufactured with precise predetermined positions that match the provisional prosthesis, eliminating the need for lengthy ingrowth periods while maintaining high precision through digital planning and guide templates.
2Manufacturing precision
If implant insertion precision is increased to less than 35 µm, then prosthesis mounting accuracy improves, but process complexity increases
Solution Approach 1:
The patent applies copying by creating a digital replica of the patient's oral cavity through tomographic imaging of the provisional prosthesis in situ. This digital model is then used to manufacture the permanent prosthesis with precise predetermined positions. The provisional prosthesis serves as a physical copy/reference that guides the creation of the permanent prosthesis, allowing high precision mounting without requiring complex manual adjustment procedures during surgery.
Solution Approach 2:
The patent applies parameter changes by transitioning from manual, experience-based implant placement to a digitally-driven process with predetermined positions and orientations. The system uses tomographic images and digital planning to define exact implant parameters (position, orientation, depth), which are then transferred to guide templates and permanent prosthesis manufacturing, reducing process complexity through standardization and automation.
3Measurement precision
If a digital model and drilling template system is implemented, then implant insertion accuracy improves, but manufacturing steps increase
Solution Approach 1:
The patent applies the intermediary principle by introducing a provisional removable prosthesis as a mediator between the patient's oral cavity and the permanent prosthesis. This provisional prosthesis is positioned and imaged to create a digital model, which then serves as the basis for manufacturing the permanent prosthesis. The intermediary captures the precise spatial relationships and allows accurate transfer of this information to the final prosthesis, improving implant insertion accuracy while consolidating multiple measurement steps into a single digital workflow.

Function Achieved in This Case
Enables immediate placement of a permanent dental prosthesis with reduced preparation time and fewer steps, ensuring high accuracy and stability of implants, applicable to both edentulous and partially dentate jaws.
Implementation Method 1
at least one digital image of the jaw with the provisional removable dental prosthesis is generated by tomography. Such an image is preferably a 3D image and is thus, for example, obtained by performing a CT scan.
