Customized Temporary Veneers for Reversible Appearance Trials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental veneer installation processes require permanent modifications to existing teeth, limiting the ability of individuals to preview the outcome before committing to a permanent change.
Innovation Solution
Customized temporary veneers that are temporarily attached to the dental arch, allowing individuals to try out various appearances and experiences before making permanent decisions, without causing damage to their teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dental veneers are permanently bonded to teeth using permanent adhesives, then the veneers provide a secure and durable attachment, but the existing teeth must be permanently modified through grinding and prepping, which limits the ability to try out different appearances before committing
Solution Approach 1:
The patent applies preliminary action by creating temporary veneers that can be tried on before permanent commitment. These temporary veneers allow patients to preview different tooth appearances and configurations without undergoing permanent modifications to their natural teeth, enabling informed decisions about whether to proceed with permanent veneers.
Solution Approach 2:
The temporary veneers serve as copies or simulations of the final permanent veneers. They replicate the appearance, shape, and fit of the intended permanent veneers, allowing patients to experience the aesthetic outcomes before committing to permanent bonding and tooth modification.
2Adaptability or versatility
If temporary veneers are designed to be easily removable without permanent adhesive, then the ability to try different appearances is improved, but the attachment strength and comfort during wear may be compromised
Solution Approach 1:
The patent applies parameter changes by using different adhesive characteristics for temporary versus permanent veneers. Temporary veneers employ reversible adhesives with controlled bonding strength that is sufficient for comfortable wear and aesthetic evaluation but allows for painless removal without permanent commitment, contrasting with the strong permanent adhesives used for final veneers.
3Shape
If the gum-proximate edge thickness is reduced to improve aesthetics and comfort, then the veneer blends better with the gum line, but the structural integrity and resistance to damage may be compromised
Solution Approach 1:
The patent applies local quality by implementing a tapered thickness profile where the gum-proximate edge has reduced thickness for aesthetic integration with the gum line, while the thickness increases toward the vestibular region to provide structural strength. This gradient thickness distribution allows different regions of the veneer to have optimized properties for their specific functional requirements.
Solution Approach 2:
The tapered geometry of the gum-proximate region creates a curved, gradual transition in thickness rather than an abrupt edge. This curved profile improves aesthetic blending with the gum line while the gradual tapering distributes mechanical stresses more effectively, preventing stress concentration that would compromise structural integrity.

AI summary
Customized temporary veneers. The customized temporary veneers are configured to be temporarily attached to a target region of an individual's dental arch and include a plurality of tooth-covering regions, at least one joining region, and a gum-proximate region. Each tooth-covering region includes a corresponding vestibular region configured to at least partially cover a vestibular surface of a corresponding tooth of the dental arch. The at least one joining region operatively attaches a pair of adjacent tooth-covering regions to one another. The gum-proximate region extends from the plurality of tooth-covering regions and is configured to extend at least partially between the plurality of tooth-covering regions and a gum of the individual's dental arch. The corresponding vestibular region defines a vestibular region thickness, and the gum-proximate region tapers from the vestibular region thickness to a gum-proximate edge that defines a gum-proximate edge thickness.
