Abstract: A method of manufacturing a dental implant wherein the resulting dental implant closely corresponds to or matches the size and shape of the extracted tooth. Generally stated, the method comprises the steps of (i) three dimensionally mapping the size and shape of the crown and root of a tooth to be extracted and (ii) using said mapping to manufacture a dental implant to correspond to the size and the shape of said crown and root of the tooth to be extracted. Further, the resulting dental implant may comprise a number of anti-migratory structural features that function to better secure the dental implant to the patient.

Abstract: A ladder accessory device for insertion into an opening in a prior art ladder rung, wherein the ladder accessory device provides an elevated work environment that is out of the path of an individual ascending/descending the ladder. The accessory device is preferably comprised of a rung insert, a rung insert locking device, a support arm, a platform arm, and a platform arm locking device. The rung insert locking device permits the support arm to be rotated about the rung insert locking device, and the platform arm is likewise rotatable about the support arm. A wide arrange of accessories may also be removably attached to the platform to increase the overall usefulness of the device.

Abstract: A skateboard truck and hanger therefor, the skateboard truck including a base plate, a bushing support, and a hanger which is dimensioned for removable securement to the bushing support. The hanger is preferably removably secured to the bushing support by means of machine screws passing through openings in the bushing support for threaded engagement in threaded openings within the hanger.

Abstract: A truck according to the present invention includes a hanger dimensioned for insertion of axles upon which wheels are attached. The truck may be configured for attachment to a skateboard. The hanger includes a cutout portion including a key cavity into which a key is positioned. Bushings and a kingpin are also installed onto the hanger. The key when positioned within the key cavity of the hanger confines the pivot of the hanger on a centerline which bisects the hanger. The key may include extending cylindrical tabs which may allow for the hanger to freely swivel about the kingpin passing therethrough without the use of bearing surfaces. The bushings are positioned on the kingpin and on opposite sides of the key and key cavity of the hanger so as to urge the hanger to its center position.
