Abstract

Dental implant of surgical impact fixation, composed of an endo-bone implant structure, constituted by a base for a crown or dental prosthesis fixed to thread on the implant itself that is inserted inside the cortical bone. The described implant structure is formed by a cylindrical shell body provided with a bevel (3) rounded at the tip, of insertion, and a rear cylindrical opening provided with internal thread (7) of threading of said dental prosthesis, the walls of said structure being provided with deep longitudinal grooves (1) engraved in the entire alveolar fixation zone, of extension of the osteo integration zone against possible implant rotations. In addition, the implant fixation zone may be complemented by two or more retentive races (2), depending on the length of the implant, against longitudinal displacements thereof.

Description

Dental implant for surgical fixation by impact.

The present invention, dental implant of surgical fixation by impact comes to consist of a novel implant characterized primarily by its special structure for impact fixing, compared to the traditional techniques of fixation, especially in spongy and poor type bones mechanical resistance characteristics.

For all this, the present invention will be of special interest for the dental prosthesis sector

The state of the art, as regards the implantation of dental prostheses, suppose complex surgical interventions for implant fixation dental, considering that these are usually done in elderly people, in which the state of the bones is fragile due to the characteristic osteopathy of the aging.

These surgical interventions involve a considerable damage to the patient's bone structure and therefore produce considerable discomfort due to aggressions caused in the implant placement process.

However, when it becomes necessary to replace a  Lost dental piece is necessary to go to this type of techniques. If part of the damaged part is available, the Dental technician can sometimes design a crown that, coupled to the piece to reconstitute, support a prosthesis of the lost piece. However, on many occasions, this is not possible. and we must find a solution to fix the prosthesis of the piece dental loss, so it is required to go to the implant through surgical procedures for restraint in bone structure.

On the other hand, implants adopt, depending on of each application, different shapes and sizes, being the implants that are placed on the bone called implants subperiosteals, which are precisely what the present invention There are also very thin implants, called pit implants.

Today implants are mainly used that resemble the root of the tooth, being called implants of root and are placed inside the bone, to act as supports of false crowns.

The use of this type of implants presents certain problems that the present invention tries to solve. We refer to the problems of achieving adequate support, preventing accidental exit of the implant, as well as avoiding any rotation of it. All this, looking for a balance with produce the minimum possible aggression in the bone structure of the patient.

For all this, the present dental implant of surgical impact fixation is constituted by a endo-bone implant structure, which consists of a base for a crown or dental prosthesis fixed to thread on the implant itself which is inserted inside the cortical bone. Described Implant structure is formed by a body of cylindrical shell fitted with a rounded bevel at the tip of insertion, and a rear cylindrical opening with thread internal threading of the referred dental prosthesis, being the walls of said structure. provided with deep stretch marks lengths recorded throughout the alveolar fixation zone, of so that the osteo zone is greatly increased integration, avoiding the possible rotation of the implant. With it get a less traumatic fixation than with other implants known in the state of the art, since the point of friction is lower, just as the anchor fixing pressure is reduces considerably, entering more smoothly.

Also, in the aforementioned implant, the previous one stretch mark implant fixation zone is located supplemented by two or more retentive races, depending on Implant length, which prevents possible displacement longitudinal thereof.

On the other hand, the described structure of implant may be provided with a concave neck termination of the implant to facilitate the closure of the socket in the segment of bone cortex

In addition, the previous structure can be found also provided at the end of the implant neck, with an area polished cylindrical finish, to allow subsequent biological growth of the mucosa in said area, improving the final implant placement.

Finally, said implant structure can also have a hexagonal opening at the end of the neck of the implant, anti-rotation of the posterior prosthetic elements.

A detailed description will be made below. of the dental implant for surgical impact fixation that advocates, with reference to the accompanying plane, in which represents a simple, non-limiting example title, a form preferred embodiment susceptible to all those variations of detail that do not imply a fundamental alteration of the essential characteristics of these improvements.

In this plane it is illustrated:

In Figure 1: Scheme of an application of dental implant for surgical impact fixation.

According to the example of execution represented, the refinements in the dental implant for surgical fixation due to impact referred to in the present invention, are constituted by the creation of a novel and original structure of dental endo-osseous implants.

The present dental implant fixation surgical impact is constituted by a structure of endo-bone implant, which consists of a base for a crown or dental prosthesis fixed to thread on the implant itself inserted inside the cortical bone. The described structure of the implant is formed by an envelope body cylindrical provided with a bevel (3) rounded at the tip, of insertion, and a rear cylindrical opening with thread internal (7) threading of said dental prosthesis, being the walls of said structure provided with deep grooves (1) lengths recorded throughout the alveolar fixation zone, of so that the osteo zone is greatly increased integration, avoiding the possible rotation of the implant. With it get a less traumatic fixation than with other implants known in the state of the art, since the point of friction is lower, just as the anchor fixing pressure is reduces considerably, entering more smoothly.

Also, in the aforementioned implant, the previous one implant fixation area with stretch marks (1) is located supplemented by two or more retentive races (2), in 5 function of the implant length, which avoid the possible longitudinal displacement thereof.

On the other hand, the described structure of implant may be provided with a concave neck termination  of the implant (4) to facilitate the closure of the socket in the bone cortex segment.

In addition, the previous structure can be found also provided at the end of the implant neck, with an area polished finish cylindrical (5), to allow subsequent biological growth of the mucosa in said area, improving the final implant placement.

Finally, said implant structure can also have a hexagonal opening (6) at the end of the neck of the implant, anti-rotation of the prosthetic elements later.

Finally, the shape, materials and dimensions they can be variable and in general everything that is accessory and secondary, as long as it does not alter, change or modify the essentiality of the improvements that have been described.
