DENTAL IMPLANT, INSERTION TOOL FOR DENTAL IMPLANT AND COMBINATION OF DENTAL IMPLANT AND INSERTION TOOL
A dental implant (1), in particular for insertion into bone tissue of a patient, comprising: a core body (2) having an apical end (4), a coronal end (6), and an outer surface (8) extending along a longitudinal direction between said apical end (4) and said coronal end (6); and at least one thread (12) located on at least a threaded portion of said outer surface (8), should have superior properties regarding primary and secondary stability. According to the invention this is achieved in that the core body (2) comprises a core shaped zone (22), preferably next to said coronal end (6), in which core shaped zone (22) the cross-section of said core body (2) has a number of main directions in which the radius measuring the distance between the center (50) of the cross section and its outer contour takes a relative maximum value and thus a higher value than in neighboring orientations, a core circular zone (20), preferably next to said apical end (4), in which core circular zone (20) the cross-section of said core body (2) is basically circularly shaped, and, as seen in said longitudinal direction, a transition zone (26) positioned between said core shaped zone (22) and said core circular zone (20), in which transition zone (26) the geometry of the cross-section of said core body (2), as a function of a parameter characteristic for a coordinate in said longitudinal direction, changes continuously from a basically circular shape next to said core circular zone (20) to a shape in which the cross-section of said core body (2) corresponds to the shape of the cross section in said core shaped zone (32). The invention further relates to an insertion tool (200) for inserting a dental implant (1, 201, 401) into bone tissue of a patient. Moreover, the invention relates to a combination of such a dental implant (1, 201, 401) and such an insertion tool (200).
DENTAL IMPLANT TO BE PLACED IN THE POSTERIOR UPPER JAW
A dental implant implantable in the upper rear maxilla following the lifting of the sinus membrane of the maxillary sinus by the crestal approach has a body with a shank shape. The body includes a main portion and, on opposite sides thereof, a first crestal proximal portion and a second apical distal part. The body is provided with a threading having a spiral shape with cutting edges. The threading extends in spiral fashion only about and along the main portion of the body and terminates before the second apical distal part, while the second apical distal part is conformed to provide an external surface free of projecting or cutting parts, and is at lest partially provided annularly with a groove or a series of grooves.
DENTAL IMPLANT MADE OF A METAL OR A METAL ALLOY
Dental implant (1) for anchoring of a dental prosthesis, wherein the dental implant (1) comprises a core (10) and an external thread (3) surrounding the core (10), wherein the dental implant (1) has an apical end (11) and a cervical end (12) to be screwed by means of the external thread (3) with the apical end (11) first into a recess formed in a jaw bone and to anchor the dental prosthesis at the cervical end (12), wherein the dental implant (1) consists of material which comprises or consists of a metal or a metal alloy, wherein the core (10) has a bulge (A) in the middle area (4) in any cross-section passing through the entire length of the longitudinal axis (L) of the dental implant.
ORTHOPEDIC IMPLANT THAT SAVES BONE CUTTING WITH DRILL BITS IN ADVANCE IN ORTHOPEDIC AND DENTAL SURGERIES
An orthopedic implant includes a main body, which has a downward tapered configuration formed of a plurality of steps of different diametrical sizes arranged along a drilling axis, each of the steps includes a cylindrical and a conical section, and the conical section of the lowest and diametrically smallest step is downward tapered into an apex; an external thread, which is externally formed on the main body to cover all the cylindrical sections but not the conical sections; a plurality of lateral cutting flutes, which are formed on the external thread into the main body and extended from the apex to the diametrically largest step with a spacing distance left between upper ends of the lateral cutting flutes and a top of the largest step. The orthopedic implant can be independently driven into a bone without the need of bone cutting using drill bits in advance and enables good osseointegration.
Narrow Diameter Dental Implant with Multi-Unit Abutment
A narrow diameter dental implant with multi-unit abutment is surgically inserted for osseointegration into the jawbone of a patient, in order to attach a crown or tooth prosthetic. The dental implant includes an implant shaft, a threading extrusion, and an attachment abutment. The implant shaft is inserted within the jawbone during osseointegration surgery. The threading extrusion is connected along the implant shaft in order to secure the dental implant within the jawbone. The attachment abutment is connected to the implant shaft, such that the attachment abutment extrudes out from the patient's gum. Therefore, the attachment abutment is accessible for the dentist to attach a crown or tooth prosthetic.
DENTAL IMPLANTS HAVING GOLDEN RATIO
A dental implant that comprises a top section having a C first length, an intermediate section having a second length, and a bottom section having a third length, wherein the first length corresponds to the third length by a preset ratio, wherein the third length corresponds to the sum of the first length and the second length by the preset ratio, and wherein the preset ratio is in the range of 1.5-1.7.
Dental implant fixture capable of easily receiving blood
A dental implant fixture as a fixture implanted in an alveolar bone to be an artificial tooth root includes a main body vertically extending long along a center axis, at least part of the main body being implanted in the alveolar bone, and a cutting face formed on an outer circumferential surface of the main body to secure a space for accommodating blood when the main body is implanted in the alveolar bone. The dental implant fixture does not apply excessive pressure to a cortical bone of an alveolar bone when being inserted into an implantation hole, and is capable of rapidly regenerating the alveolar bone by accommodating a large amount of blood inside the implantation hole.
Sub-periosteal extension for a dental implant
A dental implant comprising a subperiosteal extension, said extension extending radially beyond a radius of a post of said dental implant. A device for mounting onto a dental implant configured to extend said dental implant to comprise a subperiosteal extension, said device extending radially beyond an interface between bone and said dental implant. A method of implanting a dental implant comprising elevating a mucoperiosteal flap at site of implantation, drilling a hole for inserting a dental implant comprising a subperiosteal extension, inserting said dental implant, and covering said subperiosteal extension with said mucoperiosteal flap. Related apparatus and methods are also described.
Surgical tool with flexible shaft
An implant system can include a first rotatable flexible shaft comprising a biocompatible material and configured to be used as an implant for placement in the human body, the implant including an implant driving element positioned at a proximal end; a second rotatable flexible shaft including a cutting drill positioned at a distal end and a drill driving element positioned at a proximal end; and a surgical tool capable of being connected, in the alternative, to the drill driving element for forming a recessed surgical site and to the implant driving element for placing the implant in the recessed surgical site.
Osseous anchoring implant with optimized expansion
An osseous anchoring implant with optimized expansion, having a tubular body and a rod whose external profile of the rod and internal profile of the tubular body are complementary. The implant being expandable between a rest configuration in which an abutment mechanism interlocks the tubular body and the rod thanks to the reversal of their two respective screw pitches, so that they provide in an expanded configuration radially: a proximal bearing point, a distal bearing point, a “central” bearing point located between these two bearing points, formed by the cooperation between the outer diameter of the rod and the inner diameter of the tubular body which induce an outer diameter of the tubular body at the “central” level greater than the outer diameter of the tubular body at the proximal bearing point.
