Abstract
Embodiments of the disclosure relate to implantable objects and guiding devices, as well as recipient site preparation instruments, bone-implantable materials, and methods of fabrication and use thereof.
Core Innovation
The invention relates to methods and devices for the implantation of objects, such as implants, into bones and specifically tooth sockets. It involves the use of asymmetrical, non-threaded, custom-shaped implantable objects that match the dimension and contour of the recipient site, including changing contours to avoid critical structures. These implantable objects can be fabricated to fit specific anatomic locations, such as the shape of a tooth root, and may include bone-engaging elements such as macro-rough surfaces, grooves, flutes, fins, posts, or studs.
A novel method is provided for implanting an object into a tooth socket, comprising preparation of the site by removing the periodontal ligament, injecting a specifically defined adhesive composition, and then inserting the implantable object which matches the asymmetrical anatomy of the socket. The adhesive composition includes an aqueous medium, a powdered multivalent metal of defined particle size, and a particular acidic compound. Guiding devices may also be included to assist with precise placement and orientation.
The problem addressed by the invention is that existing subtractive site preparations for implants often cause unnecessary removal and weakening of bone, making such implants unsuitable for patients with compromised bone quality such as osteoporosis. Current protocols are complex, costly, and susceptible to errors in positioning due to unstable fixation or inaccurate placement guides. The invention aims to minimize site damage during preparation, improve fixation using adhesives, and provide implant shapes and protocols better suited to individualized anatomy and improved surgical outcomes.
Claims Coverage
The independent claim of this patent defines a method for implanting an implantable object in a tooth socket involving specific preparation, composition, and implant features.
Site preparation and adhesive-based implantation of asymmetrical, non-threaded, custom-shaped implantable object
The method comprises: 1. Preparing the tooth socket by substantially removing the periodontal ligament. 2. Injecting an adhesive composition into the prepared socket, with the adhesive comprising: - an aqueous medium, - a powdered multivalent metal having a mean particle size between 0.005 mm and 0.150 mm, - an acidic compound of Formula (I). 3. Implanting an implantable object into the prepared tooth socket, where: - the object's shape is asymmetrical and matches the tooth socket dimensions, - the object has a changing contour and is substantially free of a thread.
The claim coverage is directed to a specific method for preparing a tooth socket, utilizing a defined adhesive composition and an asymmetrical, threadless, custom-matching implantable object designed for precise anatomical fit.
Stated Advantages
The invention minimizes damage to the implantation site during preparation by avoiding unnecessary removal of sound bone.
It allows for improved fixation and load bearing support in patients with compromised bone, such as those with osteoporosis.
Custom-shaped, non-threaded implants matched to the patient’s anatomy can improve surgical outcomes and reduce reliance on bone grafts.
The adhesive composition provides primary stability and may eliminate the need for impacting or using excessive force during implantation.
Indexing techniques and the use of guiding devices enhance the precision of implant placement.
Documented Applications
Implantation of objects, including dental implants, into tooth sockets using an asymmetrical, custom-shaped implantable object and adhesive composition.
Repair of bone defects and restoration of bone or bone segments using the described adhesive and implant technique.
Use in patient populations with moderate to severe osteoporosis or other conditions leading to weakened bone.
