Dental Template Blank with Markers for Precise Implant Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing drilling templates in orthodontic implantology are labor-intensive and require an intermediate plaster model, leading to a lengthy process between initial imaging and implant insertion, as they necessitate collaboration with a dental laboratory and multiple steps.
Innovation Solution
A template blank with markers is used directly for registration, hardened with impression material on the patient's jaw, scanned, and then processed to create a drilling template, allowing for immediate production without a plaster model, enabling precise localization and planning of drill holes using CT, NMR, or Cone Beam imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a plaster model and dental laboratory collaboration are used to produce drilling templates, then manufacturing precision and reliability are improved, but loss of time and productivity deteriorate significantly
Solution Approach 1:
The invention extracts and eliminates the plaster model intermediate step from the traditional workflow. By using the patient's actual jaw as the reference base and directly attaching the template blank to it, the process removes the time-consuming laboratory fabrication step while maintaining positioning accuracy through direct registration on anatomical landmarks.
Solution Approach 2:
The invention introduces a registration system with markers as an intermediary between the patient's jaw and the treatment template. This registration system enables precise positioning and transfer of planned drill hole locations from the 3D image data to the actual patient anatomy, replacing the need for plaster models while maintaining manufacturing precision.
2Manufacturing precision
If a plaster model and dental laboratory process are used, then template manufacturing precision is improved, but device complexity and ease of manufacture worsen
Solution Approach 1:
The invention removes the complex plaster model fabrication and laboratory processing steps from the workflow. By working directly on the patient's jaw with a simplified template blank attachment process, the system reduces device and process complexity while maintaining precision through the registration marker system.
3Ease of operation
If traditional drilling methods are used without a treatment template, then ease of operation is improved, but object-affected harmful factors increase due to risk of anatomical damage
Solution Approach 1:
The invention performs preliminary planning of drill hole positions, depths, and orientations using 3D image data before the actual surgical procedure. The treatment template is pre-configured with guide structures based on this planning, allowing the surgeon to follow pre-determined safe trajectories that avoid critical anatomical structures while maintaining operational simplicity during the actual drilling.
4Loss of time
If immediate template production without plaster model is implemented, then loss of time is reduced and productivity is improved, but manufacturing precision may deteriorate
Solution Approach 1:
The registration system with visible markers serves as an intermediary that enables precise positioning even when producing the template immediately without a plaster model. The markers provide reference points that allow accurate registration of the template blank to the patient's jaw and transfer of coordinates from the 3D image data, maintaining manufacturing precision despite the accelerated timeline.

AI summary
The invention relates to a method for defining a reference system between the recording of image data which displays a patient jaw (6) and is collected by means of an image producing method and a treatment template which is movably fixed to the patient's teeth in a defined position during a surgical intervention and is provided with a tool-guiding structure, consisting in providing markers on the treatment template, in displaying said markers by means of the image producing method, in defining a reference system, in applying a template blank (13) provided with the markers (16) to at least one tooth and/or the patient's jaw in a treatable area by means of a hardenable impression material (19), in recording the image data by means of applied template blank, in removing said template blank together with the hardened impression material which is particularly break-resistant and fixed to a treatment device, in introducing a required guiding structure in the template blank by means of the treating device tools and in displacing said tools according to a planning applied to image data.
