Dental System Baseline for 3D Tooth Model Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental systems face challenges in accurately and efficiently aligning artificial teeth at anatomically ideal locations for anodontia or partial anodontia patients, leading to prolonged and inconvenient processes during digital prosthetic design.
Innovation Solution
A dental system with a baseline that modularizes a digital three-dimensional teeth model, utilizing an acquisition unit with a cross-shaped base surface and a control unit to rapidly and accurately combine the model with anatomical locations, ensuring precise engagement and pronunciation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If artificial teeth are aligned one by one without a baseline in the digital prosthetic design process, then each tooth can be individually adjusted, but the process takes a long time and it is difficult to align teeth at accurate anatomical locations
Solution Approach 1:
The patent applies preliminary action by establishing a baseline (reference line) before the actual tooth alignment process. The baseline is created by connecting anatomical landmarks (incisal edge of central incisor, cusp tip of first molar, etc.) to provide a pre-defined reference framework. This preliminary structure enables subsequent teeth to be aligned efficiently against the baseline rather than individually adjusting each tooth without reference, thus reducing design time while maintaining alignment accuracy.
2Productivity
If a baseline is introduced to rapidly and accurately place digital three-dimensional teeth models at anatomically ideal locations, then alignment efficiency improves, but the system complexity increases due to modularization requirements
Solution Approach 1:
The patent applies segmentation by dividing the dental arch into modular segments based on anatomical landmarks. Each tooth or group of teeth can be positioned as a separate digital three-dimensional model that engages with the baseline. This modularization allows for independent positioning and adjustment of each segment while maintaining overall anatomical accuracy, thereby improving alignment efficiency without requiring complete redesign of the entire dental arch at once.

AI summary
Disclosed is a dental system with a baseline so that a digital three-dimensional teeth model can be combined with an anatomical location and a plane analysis of the human body. The dental system includes an acquisition unit which is formed to be held by an anodontia patient or a partial anodontia patient in a mouth to acquire a tooth height or tooth distance of the anodontia patient or the partial anodontia patient, an analysis unit which is disposed at a maxillary landmark or a mandibular landmark of the anodontia patient or the partial anodontia patient to analyze an occlusal plane of the anodontia patient or the partial anodontia patient, and a control unit which is connected to the acquisition unit and the analysis unit, respectively to control the acquisition unit and the analysis unit to be modularized simultaneously or selectively. According to the present disclosure, since a digital three-dimensional teeth model required for design of a digital dental prosthesis required to anodontia patients having no teeth or partial anodontia patients is modularized with a baseline so as to be placed at an anatomically ideal location, the digital three-dimensional teeth model is formed to rapidly and accurately engage with the anatomically ideal location, thereby chewing and pronouncing well.
