Dental Overlay Device For Single-Visit Veneer Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental restoration methods require multiple visits and the use of temporary prostheses, which can lead to discrepancies in tooth preparation and increased risk of infection, discomfort, and inefficiency in aligning restorations with adjacent teeth.
Innovation Solution
A system and method that allows for precise preparation of teeth using a guiding device and dental instrumentation to match the internal configuration of a preformed restoration, eliminating the need for temporary prostheses and reducing the number of dental visits by preparing the tooth to mate directly with the restoration in a single visit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temporary prostheses are used during the restoration process, then the tooth is protected during manufacturing, but discrepancies occur between the prepared tooth and the internal configuration of the prosthesis
Solution Approach 1:
The invention creates a digital model of the tooth preparation before the actual preparation occurs. This digital model is used to manufacture a prosthesis with an internal configuration that precisely matches the planned preparation. By performing the digital modeling and prosthesis manufacturing in advance, the system eliminates the need for temporary prostheses and ensures accurate fit without requiring adjustments during the restoration process.
2Manufacturing precision
If multiple dental visits are required for restoration, then the tooth can be properly prepared and restoration can be manufactured, but patient inconvenience and treatment time increase
Solution Approach 1:
The invention replaces the traditional mechanical workflow of taking physical impressions, creating temporary prostheses, and making multiple adjustments with a digital workflow. A digital scanner captures the tooth geometry, software processes the data to create a precise digital model, and a computer-controlled manufacturing system produces the final prosthesis. This digital substitution enables the entire process to be completed in a single visit while maintaining or improving fit accuracy.
3Ease of manufacture
If traditional restoration methods are used, then the process is well-established, but the risk of infection and discomfort increases due to temporary prosthesis placement and removal
Solution Approach 1:
The invention extracts and eliminates the temporary prosthesis step from the traditional restoration workflow. By using digital modeling to create a prosthesis with an internal configuration that precisely matches the planned tooth preparation, the system allows for direct placement of the final restoration without requiring temporary protective devices. This removal of the temporary prosthesis step eliminates the associated risks of infection and discomfort while maintaining process simplicity through digitalization.

AI summary
A dental overlay device for the placement of one or more veneers in a mouth of a patient comprises a curved body. The curved body further includes a body surface and a plurality of holes. The body surface is complementary to and configured for contacting portions of one or more teeth in the mouth of a patient, including distal teeth on opposite sides of the patient's mouth, to secure the curved body in a suitable position on the patient's teeth. The plurality of holes extend through the curved body and correspond to locations on a plurality of teeth.
