Description

Description
APPARATUS FOR ACCELERATING OSSEOINTERGRATION
Technical Field
[1] The present invention relates to an apparatus for accelerating osseointegration, and more particularly, to an apparatus for accelerating osseointegration by flowing a current between an alveolar bone and a fixture.
Background Art
[2] An apparatus for accelerating osseointegration considerably reduces time required for osseointegration.
Disclosure of Invention
Technical Problem
[3] A conventional apparatus for accelerating osseointegration disclosed in U.S. Patent
No. 5,738,521 relates to a constant current generator powered by a 9 volt battery in order to generate an alternating electric signal having a frequency in the range of from about 40 to 100 KHz at a constant effective current in the range of from 10 to 100 mi¬ croamperes rms.
[4] However, the constant current generator has an inappropriate size to be inserted into the mouth and is thus placed on a part of the body outside the mouth. Thus, a wire must be inserted into the mouth of a patient, thereby distressing the patient. Also, when a current supplier is placed on a part of the body outside the mouth, it is almost impossible to keep supplying an electrical current to an affected part of the patient by inserting the wire from the part of the body outside the mouth into the mouth for a clinical application. Further, the constant current generator cannot accelerate osseoin¬ tegration to effectively reduce the time required to treat the affected part using the al¬ ternating current flow.
[5] Another conventional apparatus for accelerating osseointegration provides a current using a galvanic battery in an implant. However, when an electrode of the apparatus is made of silver chloride AgCl and aluminum Al, the electromotive force of the galvanic battery is theoretically about 1.9 volts, whereas the actual electromotive force is below 1.9 volts. Thus, this conventional apparatus has a voltage too low to accelerate osseoin¬ tegration. Also, silver Ag is educed from the silver chloride AgCl electrode when the current flows therethrough, and an aluminum Al ion is melted in an electrolyte to be saturated, which reduces the current. Therefore, the conventional apparatus cannot keep supplying the current required to accelerate osseointegration.
Technical Solution
[6] The present invention provides a small-sized apparatus for accelerating osseoin- tegration.
Advantageous Effects
[7] The apparatus for accelerating osseointegration according to the present invention can be easily mounted in the mouth since it has a small size and uses a minimum number of wires, thereby considerably reducing a healing period of a dental implant by increasing the rate of osseointegration.

Mode for Invention
[21] The present invention will now be described more fully with reference to the ac¬ companying drawings in which embodiments of the present invention are shown.
[22] FlG. 1 is a diagram of an apparatus for accelerating osseointegration according to an embodiment of the present invention. Referring to FlG. 1, the apparatus for ac¬ celerating osseointegration is mounted in a fixture 50 inserted into an alveolar bone, and includes a constant current generator 10, a fixing unit 20, a first current transferring unit 30 (not shown), and a second current transferring unit 40.
[23] The constant current generator 10 includes power supply (not shown) and generates a constant current. The constant current generator 10 will now be described in detail.
[24] According to the present embodiment, the height of the constant current generator
10 may not be higher than 6 mm in consideration of an opposite tooth in order to prevent inconvenience caused by food ingestion and stomatitis caused therefrom. The height of the constant current generator 10 may be between 2 mm and 4 mm and the diameter thereof may not be higher than 6 mm in consideration of a space between neighboring teeth and an error caused by inserting the fixture 50.
[25] The surface of the constant current generator 10 is formed of an insulator, which may be an engineering plastic material having good strength, elasticity, shock resistance, abrasion resistance, heat resistance, cold resistance, chemical resistance, electric insulation, etc., and the surface of the engineering plastic material may be coated to be biocompatible.
[26] According to the present embodiment, the constant current generator 10 can have the shape of a healing abutment. However, the constant current generator 10 is not restricted thereto but can be formed in the shape of a tooth or a variety of other shapes according to a part to which the apparatus for accelerating osseointegration is applied.
[27] The fixing unit 20 is inserted into the fixture 50 to fix the constant current generator
10 to the fixture 50. The fixing unit 20 has the shape of various fixtures and an upper structure. The fixing unit 20 has the shape of a screw since the apparatus for ac¬ celerating osseointegration of the present embodiment uses the fixture 50 and the upper structure in the shape of the healing abutment as illustrated in FlG. 1. According to the present embodiment, the fixing unit 20 is formed using substantially the same material as the surface insulating material of the constant current generator 10. [28] The first and second current transferring units 30 and 40 are formed using a coating wire capable of transferring a current. An edge of the second current transferring unit 40 is connected to both poles of a power supply and another edge of the second current transferring unit 40 is inserted into a surrounding tissue (skin, gingival mucosa, oral mucosa, periosteum, compact bone, cancellous bone, etc.) other than the fixture 50, or exposed in the shape of a ring surrounding the healing abutment. An edge of the first current transferring unit 30 is connected to a negative pole of the power supply, and another edge of the first current transferring unit 30 passes through the fixing unit 20 to be connected to the fixture 50. The output current of the constant current generator 10 flows in saliva or mucosa via the first and second current transferring units 30 and 40 or by means of the exposed ring.
[29] FlG. 2 is a diagram of the detailed inner constitution of the apparatus for ac¬ celerating osseointegration according to the present embodiment. Referring to FlG. 2, the constant current generator 10 includes a power supply 11 and the surface thereof is formed of an insulating material as described with reference to FlG. 1.
[30] According to the present embodiment, the rheobasic voltage of the power supply 11 supplies a variety of required current, i.e., current in the range of about 0.1 m A to about 100 m A, more desirable a current in the range of 5 m A to 20 m A for a rapid increase of the osseointegration rate when inserting the fixture 50, and most desirable a current in the range of 20 m A.
[31] Tests performed with the apparatus for accelerating osseointegration of the present embodiment showed that the rate of osseointegration increased by 20 ~ 30 % when a continuous current of 5 m A was applied, and by 50 ~ 60 % when a continuous current of 20 m A was applied.
[32] Also, test results regarding relationship between the current flow and rate of os¬ seointegration showed that the rate of osseointegration did not increase when a current below I m A was applied, the rate of osseointegration increased when a current applied increased from 5 m A to 20 m A, the rate of osseointegration decreased when the current applied increased from 20 m A to 50 m A, and a bone density decreased when a current higher than 50 m A was applied. To be more specific, the continuous current having a constant strength flows in a predetermined range, thereby accelerating os¬ seointegration around the fixture 50 and overcoming function load. Therefore, although a treatment period required for implanting the fixture 50 in an alveolar bone and connecting the healing abutment to the fixture 50 depends from patient to patient, the treatment period is generally reduced from 3 - 6 months to 6 ~ 16 weeks, which shows the relationship between the current and an osseointegration period.
[33] According to the present embodiment, the diameter and height of the power supply
11 may be smaller than 6 mm in order to easily insert the constant current generator 10 into the mouth and minimize the apparatus for accelerating osseointegration. The power supply 11, but not restricted to, can use first and second miniaturized and integrated batteries except a battery (e.g., a lithium battery easily exploded against moisture) that may cause some risk in the mouth, and form the constant current generator 10 using various batteries such as a thin film type micro battery being developed as a next generated battery. However, a kind of a power supply cannot restrict the scope of the present invention.
[34] However, since various resistance is generates according to a bone density and amount of bones, the constant current generator 10 may further include a continuous current unit 12 that automatically prevents a current higher than 2O m A from flowing.
[35] The continuous current unit 12, but not restricted to, can be manufactured in a variety of shapes such as an exclusive chip using parts in the form of a package, die, or a wafer or using ASIC processing to be embedded in the constant current generator 10.
[36] According to the present embodiment, two mercury cells having below 5 mm in diameter, about 2 mm in height, and a rheobasic voltage of 1.55 V are in serial connected to each other and inserted into the constant current generator 10 along with a constant current circuit in order to flow a continuous current of 5 m A ~ 20 m A.
[37] Therefore, the apparatus for accelerating osseointegration according to the present embodiment can be easily mounted in the mouth since it has a small size and uses a reduced number of wires. Thus, by using the apparatus of the present invention, the rate of osseointegration is considerably increased, thereby reducing a healing period of a dental implant, and greatly increasing a success rate of the implant.
[38] FlG. 3 is a diagram of an apparatus for accelerating osseointegration according to another embodiment of the present invention . The apparatus for accelerating osseoin¬ tegration according to the present embodiment is different from the apparatus for ac¬ celerating osseointegration illustrated in FlG. 1 in that a second current transferring unit 40 is not formed of wires, and a conductor surrounding the surface of the constant current generator 10 is a circular material or formed of a point (or points) 300.
[39] According to still another embodiment of the present invention, an opening is formed in the constant current generator 10 to flow a current in saliva or mucosa.
[40] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
