DISPOSITION INTRODUCED IN DENTAL IMPLANT PIN

Abstract

A disposition introduced in dental implant pin to improve and speed healing of the area after insertion of the implant pin. To this end, a pin (P) containing improvements has a central diametral reduction section (6) of diametrical reduction provided with thread fillets (7), forming a space between the bone mass (M) which will allow blood clot accumulation and natural secretions of the patient's body responsible for the prompt restoration and healing of the injured region in a considerably reduced time, besides the creation of intra-implant bone rings, offering greater support to the pin body (P), providing better dissipation of the pressure exerted during mastication .

Claims

1. (canceled)

2. A dental implant for replacement of teeth comprising: a cylindrical body, the cylindrical body further comprising: a central region with: a decreased diameter relative to the diameter of the cylindrical body upper and lower ends and left handed threading; an internal bore-hole at the cylindrical body upper end, the bore hole being threaded; and the upper and lower ends further comprise self-tapping threads for introduction of the dental implant into a bone mass bore-hole drilled into a patient; wherein the replacement tooth is implanted by screwing a threaded pin attached to a replacement tooth into the dental implant bore-hole.

3. The dental implant of claim 2 further comprising a hexagonal shoulder at the cylindrical body upper end for screwing the dental implant into the patient's bone mass.

4. A method of replacement of teeth comprising the dental implant of claim 2, comprising the steps: a dental surgeon drills a bore-hole into a patient's bone mass; the dental implant is screwed into the bone mass bore-hole using the self-tapping threads; and, the replacement tooth is screwed into the dental implant internal bore-hole using the threaded pin attached to the replacement tooth.

Description

[0013] Described briefly, it passes the implant pin to be better understood through the drawings.

[0014] FIG. 1, as stated above, refers to the state of the art, showing the implant pin created by the author of this patent application.

[0015] The following figures, from 2 to 6, refer to the pin in question, the subject of this patent application:

[0016] FIG. 2perspective view of the implant pin from its top in hexagonal shape, also showing its conical contour flange and two superb type stretches delimiting a rectilinear section of smaller diameter with thin threads.

[0017] FIG. 2bthe internal threaded bore of the pin;

[0018] FIG. 3Schematic view of the bone mass of the patient surrounded by the gingiva, in which a bore-hole was made for the insertion of the pin;

[0019] FIG. 4view according to the previous figure, with the pin being inserted into the borehole from its lower superb type thread;

[0020] FIG. 5view according to the previous figure showing that, after inserted in the borehole, the rectilinear segment of smaller diameter of the pin forms a space between this and the bone mass of the patient and the pin receives, from its hexagonal shoulder, the tooth of implant;

[0021] FIG. 6 shows the cut of bone mass already calcified around the pin, which has already received the implant tooth.

[0022] According to the attached figures, the subject of this utility model patent application is supported by a cylindrical body pin (P) formed by a top hexagonal shoulder (1), with (2), followed by a conical contour flange (3) terminating in a short neck (4), from which a superb thread (5) extends, projecting in a concave shape. Below this is a smaller vertical central rectilinear section (6) which receives left-handed thin thread (7), at the end of which a. second concave contour lower thread (8) terminates at a linear end (9) having a central rounded recess (10).

[0023] Thus, by default, after removal of the tooth to be replaced by the implant (I), the dental surgeon performs a borehole (F) per drill in the patient's bone mass (M) from the upper layer of the gingiva (G) in which the pin (P) in question is then introduced by threading from its lower superb thread (8), less aggressively than the traditional pins due to the shape of its body in a diametrical con figuration, with which the bone mass (M) receives pressure by threading only in its two short stretches of superb (8), lower, and (5) upper thread. At the end of the introduction of said pin (P), its conical contour flange (3) rests on the edge of the bed bore (F) of the bone mass (M), serving as a kind of cap which will thus seal the borehole (F), avoiding contamination of the external means.

[0024] Thus housed in the bed, the pin (P) in question, because of its differentiated diametrical configuration, creates a space between the bone mass (M) and its vertical central rectilinear section (6) of smaller diameter, such as a chamber (C), which will allow the accumulation of blood clot and natural secretions of the patient's body, which are responsible for the prompt restoration and healing of the injured region in a considerably reduced time.

[0025] When the healing and osseointegration around the pin (P) is complete thanks to the thin threaded threads (7) of its rectilinear segment (6) of smaller diameter, intraosseous bone rings are created, giving greater support to the pin body (P), thereby providing better dissipation of the pressure exerted during chewing, thus the pin (P) being ready to receive the implant tooth (D) by threading through the threaded bore hole (2) from its hexagonal shoulder (I).
