MAXIMIZED AREA OSSEOINTEGRATED CUSTOM IMPLANTS
Customized dental implants feature enhanced osseointegrable qualities by manufacturing the implant post with osseointegrable material and preparing a larger post body, including a portion to cover a prepared bone surface, to integrate with a jawbone. Resultant implants are more durable and provide a better fir into the oral cavity. Various implant shapes and designs are disclosed.
Oval section dental implant
The invention is directed to a new dental implant and associated parts that allow for insertion in narrow areas of the alveolar bone. Characteristics of the body of the implant allow for comfortable insertion in narrow bone clefts provided by its smooth narrow sections. The implant provides an alternative to complex and time consuming surgical processes involving bone regeneration and/or grafting.
Dental implant
A dental implant with an implant extension which are formed along a longitudinal axis: the dental implant has an apical end, a coronal end and a section for receiving; securing an abutment; the implant extension is formed in one piece with the implant; extends away from an end face of the apical end along the longitudinal axis, the implant extension having a first section along the longitudinal axis with an annular constriction which is directly connected to the end face of the apical end of the implant; the implant breaks off from the implant extension at the constriction, along the longitudinal axis following the first section, wherein the second section, splined shaft section being further away from the implant than the first section, perpendicular to the longitudinal axis, an outer annular groove being designed to hold the implant extension by clamping the groove in the direction of the longitudinal axis.
Prosthetic assembly and method for producing the same
The present invention relates to a prosthetic assembly (1, 10, 100) comprising a prosthetic component (2, 20, 200) and a retention screw (6, 60, 600) with an interference geometry (5, 50, 500) designed to allow relative rotation, limit relative longitudinal motion and inseparably join the prosthetic component (2, 20, 200) and the retention screw (6, 60, 600). The interference geometry (5, 50, 500) can be in the form of a ring attached to the retention screw (6) in a portion of the body of this screw (6) having a smaller diameter, or in the form of one or more inwardly folded flaps integrated in the prosthetic component (20) and diametrically distributed around the base thereof, or in the form of a uniform, tapered and hollow projection of the lower portion of the prosthetic element (200). The invention further relates to a method for producing the disclosed prosthetic assembly (1, 10, 100), including the following steps: forming a prosthetic component (2, 20, 200) having a central hole (8, 80) for receiving the retention screw (6, 60, 600), forming a retention screw (6, 60, 600), the body of which has a portion having a smaller diameter (62, 602), inserting the retention screw (6, 60, 600) into the central hole (8, 80) of the prosthetic component (2, 20, 200), and forming an interference geometry (5, 50, 500) between the base of the prosthetic component (2, 20, 200) and the body of the retention screw (6, 60, 600).
AXIAL DIRECTION AND DEPTH CHECKING GUIDE PLATE FOR IMPLANTING AND MANUFACTURE METHOD THEREOF
The present disclosure a manufacture method of axial direction and depth checking guide plate for implanting, comprises the following steps: S1: obtaining dentition data by an optical scanner, obtaining a preoperative model; virtually arranging the teeth to obtain a virtual waxing; taking Cone Beam Computed Tomography to obtain the jaw data; S2: determining the type and specification of implant, adjusting the three-dimensional position of the implant; S3: customizing an abutment, and obtaining the abutment data and model data after fitting of the dentition data and the jaw data; S4: constructing abutment cylindrical features, deviating to the labial/buccal side and lingual/palatal side respectively, and constructing the offset cylindrical features again; S5: creating the indicator rod, and fitting with the labial/buccal and lingual/palatal prototype separately to obtain the definitive indicator rod data; S6: designing an occlusal plate and connecting with the indicator rod, completing design of the guide plate, and 3D printing.
Dental implant
A dental implant for securing an abutment to a jawbone, the implant including a tapered body having a longitudinal axis, the body including a coronal end and an apical end, the coronal end including an inclined coronal surface. A first bore receives a base portion of the abutment, the first bore extending downwardly from the coronal surface and parallel to the longitudinal axis of the body. A second bore with a footprint larger than the first bore includes a flange adapted to be abutted by a top portion of the abutment, the diameter of the second bore being off-axis and larger than that of the first bore.
A DENTAL IMPLANT ANALOG
The present invention relates to a dental implant analog, an implant analog kit comprising the dental implant analog, the combination of a physical model of a set of a patient's teeth and the dental implant analog and a method of positioning a dental implant analog into a physical model of a set of a patient's teeth.
IMPLANT DEVICE
An implant device includes an implant with a threaded portion and a drilling portion and a positioning hole respectively formed at two ends of the implant. Channels are recessedly formed on an outer surface of the implant. Each channel includes pore units joined one another in a row. An interior of each pore unit includes a first area enclosed by a peripheral wall and a second area defined between adjacent surface portions and communicating with the first area. The peripheral wall has first projecting units formed thereon to present a surface with concavities and convexities. Second projecting units extend outwards from adjacent peripheral walls and overlap one another between every two adjacent channels to define each surface portion. Cells derived from a target part are quickly attached to the channels and linked with each other for enhancing the combination between the implant and the target part.
Dental implant having split fins
The present invention relates to a dental implant having at least one but preferably a plurality of split fins that are vertically spaced along the vertical axis of the body portion of the implant. These split fins hold the body portion of a dental implant stationary within the patient's jaw by engaging the patient's jawbone and promoting osseointegrationthe growth bone around and on the surface of the implant. Each split fin has a first end that is vertically spaced from a second end along the implant body's vertical axis such that the split fin extends from the first end and around the body's circumference along an inclined plane until it terminates at the second end so that the split fin creates a single spiral that extends around the entire circumference of the body portion of the implant.
Titanium nano-scale etching on an implant surface
A method of forming an implant to be implanted into living bone is disclosed. The method comprises the act of roughening at least a portion of the implant surface to produce a microscale roughened surface. The method further comprises the act of immersing the microscale roughened surface into a solution containing hydrogen peroxide and a basic solution to produce a nanoscale roughened surface consisting of nanopitting superimposed on the microscale roughened surface. The nanoscale roughened surface has a property that promotes osseointegration.
