Artificial tooth system

ABSTRACT A dental implant system to provide a mechanically self-sufficient artificial tooth possessing a functional pseudo peridontal ligament that does not cause resorption of the supporting bone and ultimate loss is disclosed. The im-plant includes a core component that withstands the masti-catory loadand transmits such load to the root system. The root system comprises an outer component that adheres to the jawbone and possesses a similar modulus of elasticity thus capable of transmitting masticatory stresses along its interface with the bone without excessive stress concentrations and an intermediate component adhering tightly to both the core component and the outer component and having a much lower modulus of elasticity than either the core com-ponent and the outer component. The longitudinal movement of the core component causes the oblique or diagonal stretch-ing of the intermediate component which pulls or applies a force on the outer component which tends to contract it and creates tensile stresses in the portions of the supporting jawbone which interface with the outer component. Such tensile stresses cause bone deposition and stabilize the implant further.

How to preserve length during bone repair

Prosthetic stem with cement sleeve

An artificial joint is capable of harmoniously connecting the artificial joint, cement and a bone and facilitating effusion of the cement at the time of implantation, as well as diminishing the stress applied thereto. The artificial joint includes a head, a neck and a stem, the stem being coated in advance with cement so as to easily bond the cement to cement filled in a bone cavity of a human femur. An effusion path for effusing the cement filled in the bone cavity is formed in a longitudinal direction on a surface of the cement coated on the stem so that the cement filled in the bone cavity of the human femur can be easily effused upward through the effusion path when the stem is inserted.

Prosthetic implant for use without bone cement

A prosthetic implant which has an attachment portion for insertion into or attachment to a patient's bone without bone cement and in which the outer surface of the attachment portion which is to be attached to said bone has a first layer made of synthetic resin material over which is secured a second layer made of a metallic material, a first and proximal portion of said second layer being porous or roughened to encourage bone ingrowth or ongrowth and a second and distal portion of said second layer being less porous, substantially non-porous or less roughened in relation to the first portion, or smooth.

Bone implant augment method and apparatus

The strength of bone implant attached to a bone is improved by using hybrid inserts which have stems and wings having bone ingrowth surface features and caps having outer surfaces of cured polymethyl methacrylate (PMMA). The stems and wings of the hybrid inserts are inserted into living bone and the bone implant is attached to the hybrid inserts with PMMA cement. Over time, the bone grows into the bone ingrowth surface features. The bone ingrowth strengthens the bonding of the hybrid inserts and the bone implant with the bone over time. The hybrid inserts increase the shear, tensile and torque strength of the bone implants. Bone inserts that do not have ingrowth surface features loosen over time.

Functional and biocompatible intervertebral disc spacer containing elastomeric material of varying hardness

The construction and manufacturing technique for a functional biocompatible intervertebral disc spacer is described. This device is useful for a replacement for a degenerated disc in certain treatments of back pain and spinal disease. The disc spacer possesses mechanical properties skin to those of the normal disc and will preserve normal functions of the spinal motion segment. The device achieves the desired properties by varying the hardness of the elastomeric material in its nucleus and annulus.

Spinal implants

Spinal implants having at least one of several attributes, including a surface layer of demineralized bone, a beveled edge, and channels in the faces in contact with adjacent vertebral bodies. Preferably, the implant has a generally planar top surface, a generally planar bottom surface, and a side surface, wherein at least one of the top and bottom surfaces is demineralized to a depth of from 0.8 mm to 3mm. Preferably, the top and bottom surfaces of the implant are textured. Also preferably, the implant is disk shaped and comprises an insertion side extending at least 10% of the circumference of the implant, wherein the edge formed by the insertion side and the top surface, and the edge formed by the insertion side and the bottom surface, are beveled.

Bicompartmental implants and method of use

The present invention provides a method and device for restoring individual patient joint kinematics using minimally invasive surgical procedures. The instrumentation of the invention sculpts the articular surface of a first bone that normally articulates in a predetermined manner with a second bone. The instrumentation includes a bone sculpting tool and a mount for attaching the tool to the second bone. The implant system is comprised of implants that provide intraoperative surgical options for articular constraint and facilitate proper alignment and orientation of the joint to restore kinematics as defined by the individual patient anatomy.
