Dental Model Analog Insertion via Coronal Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating physical dental models for dental implants are inefficient, particularly in cases where the dental implant is positioned at an awkward angle, making it difficult to insert a dental analog in the conventional apical direction.
Innovation Solution
A system and method for manufacturing a physical dental model that includes a virtual model creation process, where a virtual representation of dental surfaces and a virtual analog structure are used to generate a physical model with an analog installation structure, allowing the dental analog to be inserted in a general coronal direction.

Engineering Contradiction Analysis
1Adaptability or versatility
If the dental implant is positioned at an awkward angle, then the dental implant can be implanted in diverse anatomical locations, but it becomes difficult to insert the dental analog in the conventional apical direction
Solution Approach 1:
The patent inverts the conventional insertion approach by allowing the dental analog to be inserted in a coronal direction (from the crown side toward the root) rather than the traditional apical direction (from the root side upward). This inversion enables analog insertion even when the implant is positioned at awkward angles, as the coronal insertion path can be routed around the implant structure through the bone and soft tissue, avoiding interference with the implant's angular orientation.
Solution Approach 2:
The patent introduces a new spatial dimension for analog insertion by utilizing the coronal direction (vertical dimension from crown to root) instead of the conventional apical direction. This dimensional change allows the analog to be inserted through a path that is spatially separated from the implant's angular orientation, enabling flexible placement in diverse anatomical locations without being constrained by the implant's specific angle.
2Ease of manufacture
If the dental analog is inserted in the conventional apical direction, then the insertion path is straightforward, but the surface details of the dental model are disturbed
Solution Approach 1:
The patent inverts the insertion direction from apical to coronal, which fundamentally changes the insertion path. The coronal insertion route allows the analog to be introduced through the crown side and routed around the implant, thereby avoiding direct contact and disturbance of the dental model's surface details in the apical region, while still achieving proper analog positioning.
Solution Approach 2:
The patent uses the coronal direction as an intermediary path that mediates between the insertion requirement and the preservation of surface details. By routing the insertion path through the coronal dimension rather than directly through the apical surface, the surface details serve as a mediator that guides the insertion path while being protected from disturbance.

AI summary
A method may include generating a first virtual model of a dental structure of a patient from three-dimensional scan data, identifying a first virtual surface of the first virtual model corresponding to a first portion of the soft dental surfaces that surrounds a location of the restorative object, separating the identified first virtual surface of the soft dental surfaces from at least the portion associated with hard dental surfaces to create a second virtual model of a soft model part and a third virtual model of a hard model part, and outputting a composite model including a first model part of a soft material and a second model part of a hard material, the first model part corresponding to a shape of the second virtual model and the second model part corresponding to a shape of the third virtual model.
