The present invention relates to a connection assembly for attaching a dental component to a dental implant, a dental component for the connection assembly and a method to use the connection assembly. The connection assembly (100; 1100; 2100; 3100) is removably attachable to the dental implant (10; 1010; 2010; 3010), preferably with the dental component (20; 1020; 2020; 3020) attached to the connection assembly, and a dental component is attachable to the connection assembly in a pre-fastened state or a fastened state. The pre-fastened state, when the connection assembly is attached to the dental implant, the connection assembly allows for adjustment of a relative position and/or orientation between the dental component and the dental implant. In the fastened state, the relative position and/or orientation between the dental component and the connection assembly is fixed, while the connection assembly is in particular detachable from the dental implant with the dental component attached to the connection assembly in the fastened state.

A dental implant adapted for implanting within a jaw bone, the implant comprising a horizontally-oriented body having a length extending in the mesial-distal direction of the jaw bone, the body having a threaded cavity dimensioned for receiving a prosthetic abutment, and wherein the cavity comprises an opening that is located wholly within a buccolingual width of the body.

The present invention provides a dental implant that can deal with a subsequent reduction in bone mass while reducing a burden on a patient, and a set thereof. The present invention is directed to a dental implant comprising: a first stage implant 1 that has a bottomed tubular shape, a male thread 3 formed on an outer periphery thereof, and a female thread 4 formed in an inner periphery thereof; and a second stage implant 2 that has a tip part 6 having a male thread 5 threadably engaged with the female thread 4 of the first stage implant 1 and a rear end part 7 to which an upper prosthesis is to be attached via an abutment 8, wherein the female thread 4 of the first stage implant 1 and the male thread 5 of the second stage implant 2 are tapered threads.

A method for mounting a dental restoration includes advancing an implant engaging portion of an abutment into an opening in a dental implant. The implant engaging portion is integrally formed with a component supporting portion terminating in a coronal end of the abutment. With the abutment in mating engagement with the implant, the method also includes advancing a temporary coping in a coronal direction over the component supporting portion of the abutment. During the advancing of the coping, the method further includes snap-fitting at least one first snap-fit retention feature on an outer peripheral surface of the component supporting portion with at least one second snap-fit retention feature integral with an interior surface of the temporary coping. The at least one first snap-fit retention feature is located at an axial location along the component supporting portion proximate to a location where the implant engaging portion meets the component supporting portion.

Implants for anchoring within bone are provided herein. An implant may include at least one thread extending around a core in a plurality of turns from the coronal region to the apical region. The thread(s) has a thread outer diameter that may define a cylindrical portion, wherein the thread outer diameter remains constant for more than one turn around the core, and define a conical portion, wherein the thread outer diameter decreases at a thread diameter decrease rate in the apical direction. The thread(s) may have a plurality of notches spaced radially and longitudinally from one another. The notches may be partially notched to reflect a portion of a semi-spherical surface and partially notched to reflect a portion of a semi-cylindrical surface.

An abutment is obtained that enables an operation of detaching the abutment from a fixture to be readily performed without having a patient open his/her mouth wide while inhibiting accidental ingestion or swallowing of an abutment that comes off. In a dental implant 100 comprising a fixture 110 and an abutment 120, when a fitting recess 121 of the abutment 120 is fitted onto a fixture head 112 so that a space is formed between a top surface 112b 1 of the fixture head 112 and a bottom surface 121a of the fitting recess 121, the fixture head 112 is secured to the fitting recess 121 by a frictional force, and an instrument insertion hole 129 for inserting an instrument for disengaging the securement by the frictional force in the space is formed on a sidewall 121c of the fitting recess 121.

Root canal abutment devices and methods which facilitate the adjustment or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured within a pulp chamber of a pre-existing tooth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy sleeves or plates or elements extending along the abutment. Each of the sleeves has a length with at least one curved or arcuate portion. Energy may be applied to the elements such that the arcuate portion flattens to allow for the oral appliance to be placed thereupon while removal of the energy allows the elements to reconfigure into its curved configuration thereby locking the oral appliance to the abutment. Removal of the oral appliance may be effected by reapplication of energy to the elements.

The present invention relates to a connection between a post part provided for being screwed into the jawbone and an associated superstructure part to which a dental prosthesis can be fastened. The connection between the post part and the superstructure part has a rotational self-centering action, wherein at least one of the surfaces provided for this purpose has a friction-minimizing modification and/or coating.
