Angulated Dental Implant With High-Strength Titanium Bore Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angled dental implants with internal connections require larger diameters to accommodate angled features, leading to thinner walls that are prone to failure, and are unsuitable for anterior maxilla/mandible due to insufficient bone support.
Innovation Solution
Dental implants made from cold-worked, high-strength commercially pure titanium with a non-rotational feature and angled interior bore, allowing for smaller diameters and enhanced structural integrity through varying wall thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If angled dental implants with internal connections are designed with larger diameters to accommodate angled features, then the structural integrity is improved, but the device becomes unsuitable for anterior maxilla/mandible due to insufficient bone support
Solution Approach 1:
The patent changes the material parameter from conventional materials to cold-worked, high strength, commercial pure titanium with ultimate tensile strength of at least about 900 MPa. This material parameter change enables the implant to achieve sufficient structural integrity with a smaller outer diameter (3.0-4.0 mm), making it suitable for anterior maxilla/mandible while maintaining the angled internal connection features
2Adaptability or versatility
If angled dental implants are made with smaller outer diameters for anterior maxilla/mandible, then adaptability is improved, but the wall thickness becomes too thin causing the implant to break or fail
Solution Approach 1:
The patent applies parameter changes by using cold-worked, high strength, commercial pure titanium with ultimate tensile strength of at least about 900 MPa. This material parameter enables the implant to have a smaller outer diameter (3.0-4.0 mm) while maintaining adequate wall thickness and resistance to breakage, thus achieving both adaptability and reliability
3Adaptability or versatility
If the outer diameter is reduced to fit anterior maxilla/mandible, then the implant becomes more adaptable, but the varying wall thickness creates weak points that are prone to failure
Solution Approach 1:
The patent uses cold-worked, high strength, commercial pure titanium with ultimate tensile strength of at least about 900 MPa to maintain uniform strength distribution despite varying wall thickness. The high strength material compensates for the thinner wall sections created by the angled internal bore, ensuring no weak points that are prone to failure while maintaining small outer diameter for adaptability

AI summary
A dental implant includes a generally cylindrical body, an interior bore, and a non-rotational feature. The generally cylindrical body has a main-central axis and is formed from cold-worked, high strength, commercially pure titanium having an ultimate tensile strength of at least about 900 MPa. The generally cylindrical body has a proximal portion and an opposing distal portion for anchoring the dental implant in bone of a patient. The interior bore is formed in the generally cylindrical body and has (i) a bore-central axis and (ii) a threaded portion for receiving a screw that is configured to removable hold an abutment in engagement with the dental implant. The non-rotational feature is configured to engage the abutment in a non-rotational fashion.
