A dental implant supported on the cortical bone is implanted in the socket from which the tooth was extracted, if this hole still exists, or in the remaining socket when the tooth was extracted some time before, or alternatively in a hole made for placement of the implant, at cortical bone level, and externally, between the cortical bone and the gingiva, slightly embracing the mandible and the maxilla.

In one embodiment, in order to enhance the fixation and implant lifetime vascularization, the implant of the present disclosure for fitting in an intraosseous zone of a dental socket includes a plurality of raised platforms with a flat top such that said tops form an external surface of the implant for contacting with the intraosseous zone and the spaces between said platforms form a network of channels for revascularisation fluid flow with capillarity properties.

The invention relates to a method for the repeated activation of orthodontic correction devices with a known critical temperature (Tkrit) and a glass transition temperature (Tg) lying above the critical temperature. In the method according to the invention, in order to guarantee gentle repeated activation, an orthodontic correction device is heated to a temperature that lies above the critical temperature but below the known glass transition temperature. The invention also relates to a device for performing the method.

Disclosed is a method for manufacturing a fitting device for an orthodontic apparatus, including: the following steps: making a first image of a row of teeth in an initial position, and a second image of the orthodontic apparatus; the apparatus including two attachment elements connected by a bridge, each attachment element capable of being connected to a tooth; making a third image of the orthodontic apparatus joined to the teeth in the initial position; then making a fourth image of the fitting device, including a contact surface capable of being joined to the teeth; two complementary first cavities of the attachment elements; and a second cavity capable of receiving the bridge; then additively manufacturing the fitting device from the fourth image.

An elastic matrix band for use during a dental restoration process is provided. In one embodiment, among others, the matrix band may include an elastic circular band that has a first end and a second end. The elastic circular band includes an opening at the second end, and the first end has a larger diameter than the second end. The elastic circular band is configured to expand in order to situate the elastic circular band around a tooth and contract in order to adhere to the tooth. Additionally, the elastic circular band comprises a ridge that is positioned between the first end and the second end.

Process for programming an orthodontic component from a shape memory material starting from an initial shape of the orthodontic component into a target shape to be programmed of the orthodontic component, wherein the target shape compared to the initial shape at least sectionally has a severe bending, the process comprising the following steps: a. providing an orthodontic component (1) of a shape memory material in an initial shape, b. creating a target baking mold for the orthodontic component (1), c. inserting the orthodontic component (1) into the target baking mold, and d. baking the orthodontic component (1) in the target baking mold in order to program it into the target shape, characterized by the following steps after step a) e. creating at least one intermediate baking mold for the orthodontic component (1), in which intermediate baking mold the orthodontic component (1) has an intermediate shape between the initial shape and the target shape, f. inserting the orthodontic component (1) into the intermediate baking mold, and g. baking the orthodontic component (1) in the intermediate baking mold.

Device for injecting a filling material in the fluid phase into a canal space, the device including an adaptor nozzle connected to an auto-mixer, and an injection tip fitted at the upper end of the auto-mixer. At a distal end the injection tip has an outside diameter of 1.5 mm or less over a length of 8 mm or greater. The injection tip is made of memory shape material for bending to a desired orientation. The injection tip is molded to the upper end of the auto-mixer, and on an exterior surface of the injector tip are either circular ribs defining a groove, the upper end of the auto-mixer being molded into the groove so the injection tip is locked in position in the upper end while retaining a degree of freedom to rotate about its axis of symmetry, or one or more mutually parallel circular ribs, and the upper end of the auto-mixer is molded onto the circular rib so the injection tip is blocked in position in the upper end while retaining a degree of freedom to rotate about its axis of symmetry.

The present technology comprises methods of manufacturing an orthodontic appliance. For example, a method can include forming an orthodontic appliance in an intermediate configuration by a casting process. The method can further include securing the appliance to a shape forming fixture such that the appliance assumes a desired configuration. The shape forming fixture can comprise a gingiva portion including a surface having a shape corresponding at least in part to a gingiva of a patient and a securing portion carried by the gingiva portion and configured to releasably secure to a portion of the appliance. The method can further include setting a shape of the appliance while the appliance is secured to the shape forming fixture.

An orthodontic device (10) comprising, a first opening (11) for receiving a first anchoring structure, a second opening (12) for receiving a second anchoring structure and a third opening (13, 14, 15) for receiving a third anchoring structure, the first, second, and third anchoring structures being attached in a mouth of a subject, and an intermediate structure (18) connecting the first, second and third openings, wherein one or more of the openings are stretchable, and wherein the intermediate structure and the openings are made from a creep resistant material.

Proposed is a removable retainer including a body part that is formed of a shape memory alloy material and has a front surface in close contact with the outer tooth surface of each tooth, and a fixing part coupled to the body part and fixing the body part, wherein the body part includes a curved protrusion part formed to protrude toward an interdental space to be inserted into the interdental space, and multiple support parts. A manufacturing method of the removable retainer includes a step of acquiring three-dimensional scanning data, a data processing step of generating first and second processing lines, a laser cutting step of laser cutting a flat plate-shaped base material to form a body-part forming part, a shape processing step of cutting the body-part forming part, and a fixing part coupling step of coupling the manufactured body part and the manufactured fixing part to each other.

One aspect of the present invention is a self-ligation type orthodontic bracket which has a simple structure and in which a shutter can be reliably opened and closed, and fixed. The orthodontic bracket is provided with: a bracket body having a slot to which a wire is attached and an introduction port connected to the slot; a shutter provided between the slot and the introduction port to be able to move forward and backward; and a stopper wire which is attached to the bracket body and prevents the shutter from detaching. The stopper wire is elastic. Both end parts of the stopper wire are supported by the bracket body. When the shutter is closed, the central part of the stopper wire is located at a position which blocks the path along which the shutter moves forward and backward.
