Dental Implant Assembly for Uniform Distribution Of Occlusal Forces

摘要

A dental implant abutment assembly imitates a micro-motion mechanism to direct occlusal forces internally, and uniformly distribute the occlusal forces into the body of an ossoeintegrated dental implant. The micro-motion mechanism is configured to imitate the biomechanical behavior of the periodontal ligament through a compressive action that dampens vertical, horizontal, and angular forces. A compressive ring provides a dampening effect to supportive components of the assembly. A compressive coil redirects vertical forces along a longitudinal axis of the assembly. An implant body osseointegrates into the dental alveolus. A central mobile element seats in the dental body. The compressive coil extends along the central mobile element to absorb vertical forces. The compressive ring seats on the collar of the dental implant. A threaded cannulated housing securely holds the central mobile element and the compressive coil to form a single unit. A restorative abutment portion threadably seats on the central mobile element.

1. A dental implant abutment assembly for uniformly distributing and dissipating occlusal forces, the assembly comprising:
a dental implant defined by a an implant body comprising an external threaded surface and an internal threaded bore, a collar, and a restorative platform; a central mobile element defined by a threaded superior portion separated by a shoulder portion from an inferior portion; a compressive coil configured to wrap around the length of the inferior portion of the central mobile element, the compressive coil extending approximately between the shoulder portion and the inferior portion of the central mobile element; wherein the compressive coil at least partially supports vertical displacement of the central mobile element for uniformly distributing occlusal forces; a threaded cannulated housing defined by a hollow chamber, an inner housing channel, an outer housing threaded surface, a terminal end, and a locking end, the locking end having an inner ridge and an external locking surface, wherein the inner housing channel is configured to enable passage of the threaded superior portion of the central mobile element so that a space forms between the threaded superior portion of the central mobile element and the external locking surface of the cannulated housing, and the inner ridge of the locking end engages the dental implant collar, and wherein the outer housing threaded surface is disposed to rotatably secure with the internal threaded bore of the dental implant body; a compressive ring having a central hole, wherein the threaded superior portion of the central mobile element passes through the central hole of the compressive ring, so that the compressive ring positions on the restorative platform of the collar of the dental implant, and substantially occupies the functional space formed between the threaded superior portion of the central mobile element and the external locking surface of the housing; and a restorative abutment portion defined by an inferior aspect having a threaded cavity and a superior aspect having a threaded central bore, the inferior aspect of the restorative abutment portion is disposed to engage the compressive ring and the threaded superior portion of the central mobile element is configured to pass through the central cavity of the inferior aspect of the restorative abutment portion, so that the compressive ring is operatively arranged to dampen occlusal forces on the restorative abutment portion.
