Dental Implant with Resorbable Core for Bone Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental implants face instability and failure due to unsuitable dental bone conditions, such as soft bone or osteo-disorders, leading to potential fractures or infections, and existing solutions like bone grafting are time-consuming and may not provide adequate initial stability for smaller implants.
Innovation Solution
Incorporating a resorbable material into a dental implant with a center bore and channels that distributes into the bone cavity to form a stabilizing layer between the implant and bone, enhancing initial stability and facilitating osseointegration, even in smaller implants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bone grafting procedure is performed to augment dental bone, then the suitability of dental bone for implant receipt is improved, but the treatment time is significantly extended by 12-16 weeks
Solution Approach 1:
A resorbable material acts as an intermediary substance placed within the bone cavity to provide immediate structural support and stability for the implant. This mediator allows the implant to be installed immediately without requiring lengthy bone grafting procedures, as the resorbable material temporarily compensates for insufficient bone quality and gradually integrates with the surrounding bone tissue.
Solution Approach 2:
The resorbable material is pre-placed in the bone cavity before implant insertion to prepare the site for immediate implant installation. This preliminary action eliminates the need for staged bone grafting procedures by providing the necessary structural foundation in advance, allowing the implant to achieve primary stability immediately upon insertion.
2Adaptability or versatility
If a smaller dental implant is used to match space limitations, then the adaptability to oral cavity constraints is improved, but the initial stability of the implant deteriorates
Solution Approach 1:
The resorbable material serves as a stabilizing intermediary that fills the space between the smaller implant and the bone cavity walls. This intermediary provides additional support and distribution of mechanical loads, compensating for the reduced surface area of smaller implants and ensuring adequate initial stability even when the implant size is constrained by available space.
Solution Approach 2:
The resorbable material is specifically placed in the local region between the implant threads and the bone cavity to provide targeted stabilization. This localized quality enhancement allows the smaller implant to achieve sufficient stability in specific areas where space is limited, without requiring the implant itself to be larger.
3Adaptability or versatility
If threads of a smaller implant do not contact surrounding bone during implantation, then the adaptability to bone cavity size is improved, but the initial stability deteriorates
Solution Approach 1:
The resorbable material acts as a mediator that fills the gap between the implant threads and the surrounding bone when the implant is smaller than the bone cavity. This intermediary substance provides the necessary mechanical interlocking and stability that would otherwise be provided by direct thread-to-bone contact, enabling successful implantation of smaller implants in appropriately sized cavities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The resorbable material provides immediate stability and promotes bone growth around the implant, reducing the risk of failure and allowing for successful osseointegration, especially in cases where bone quality is compromised.
Implementation Method 1
one or more channels extending between the center bore and an exterior surface of the body portion... permitting the resorbable material to flow from the center bore, through the one or more channels, and into the dental bone cavity

AI summary
Dental implant devices, kits, and methods for implantation or use in a bone cavity, are disclosed. A dental implant can include a body portion, extending from a proximal end to a distal end along a longitudinal axis, including a central bore extending from the proximal end to a termination point, located proximal of the distal end. The dental implant can further include and one or more channels extending between the central bore and an exterior surface of the body portion. A kit can include a set of different sized dental implants, a set of slugs including a resorbable material, and optionally, an injection tool. A method can include inserting the dental implant into a bone cavity, introducing a resorbable material into the central bore of the body portion, and permitting the resorbable material to flow from the central bore, through the one or more channels, and into the bone cavity.
