Abstract
Description
本発明は、特に、歯牙のう触、歯周病あるいは歯列矯正等による歯牙欠損、または治療のために抜歯を行なった際の歯牙再生術として、上顎臼歯部に人工歯根の埋入を施す際に、上顎骨臼歯部が骨吸収等により骨高さの不足が生じた場合に行なう上顎洞底挙上術に使用する上顎洞底挙上術用器具に関する。 In particular, the present invention applies an artificial tooth root to the maxillary molar part as a tooth regeneration method when tooth is removed due to tooth contact, periodontal disease or orthodontics, or tooth extraction for treatment. In particular, the present invention relates to a maxillary sinus floor elevation device used for maxillary sinus floor elevation when the maxillary molar portion is deficient in bone height due to bone resorption or the like.
上顎骨に埋入する人工歯根に対し、上顎骨臼歯部の骨高さの不足が生じている症例には、上顎洞底挙上術を施す必要が有り、例えば、米国特許第5961329号公報には、人工歯根およびその人工歯根床の形成方法が記載されている。 In cases where the bone height of the maxillary molar portion is insufficient with respect to the artificial tooth root embedded in the maxilla, it is necessary to perform maxillary sinus floor elevation, for example, in US Pat. No. 5,961,329 Describes an artificial tooth root and a method for forming the artificial tooth root bed.
図2は、上顎洞底挙上術を行う状態を示す断面図である。図3および図4は、従来の上顎洞底挙上術用器具を示す斜視図である。 FIG. 2 is a cross-sectional view showing a state in which the maxillary sinus floor elevation is performed. 3 and 4 are perspective views showing a conventional maxillary sinus floor elevation instrument.
図示したように、人工歯根床(8)を形成しようとする部分の上顎骨(13)は、歯冠(14)および歯根(15)が健康である部分の上顎骨(13)と比較して、上顎骨臼歯部の骨高さが不足している場合がある。 As shown, the portion of the maxilla (13) where the artificial root bed (8) is to be formed is compared to the portion of the maxilla (13) where the crown (14) and root (15) are healthy. The bone height of the maxillary molar portion may be insufficient.
従来の上顎洞底挙上術用器具の一実施例としては、器具先端部(1)から、屈曲部(2)および屈曲部(3)を経由し、端部が平面形状あるいは球面形状である槌打部(18)が設けられた器具取手(17)までが一体に構成される。器具先端部(1)には、器具先端凹部(7)が形成されている。このような上顎洞底挙上術用器具は、例えば特開2003−199773号公報に記載されている。 As an example of a conventional instrument for raising the maxillary sinus floor, the end is flat or spherical from the distal end (1) of the device via the bend (2) and bend (3). The instrument handle (17) provided with the striking portion (18) is integrally formed. An instrument tip recess (7) is formed in the instrument tip (1). Such an instrument for raising the maxillary sinus floor is described in, for example, Japanese Patent Application Laid-Open No. 2003-199773.
上顎洞底挙上術の施術時には、例えば、特表2003−84426号公報に記載されているようなインプラント用のドリルを使用して、上顎骨(13)に対して人口歯根床(8)を穿孔し、上顎洞底骨(9)を薄く残した状態とする。その後、人口歯根床(8)に器具先端部(1)を挿入し、槌打部(18)を、図示しない槌にて槌打することにより、上顎骨(13)が円形に貫通するように骨折させて、上顎洞粘膜(11)と共に上顎洞(16)内への挙上を行なう。従って、上顎洞底骨(9)は、上顎洞底骨(10)の位置に到る。 When performing maxillary sinus floor elevation, for example, using an implant drill as described in JP-T-2003-84426, the artificial tooth root bed (8) is attached to the maxilla (13). Perforation is performed with the maxillary sinus floor bone (9) left thin. Thereafter, the instrument tip (1) is inserted into the artificial tooth root bed (8), and the hammering portion (18) is hammered with a hammer (not shown) so that the maxilla (13) penetrates circularly. The bone is broken and raised into the maxillary sinus (16) together with the maxillary sinus mucosa (11). Therefore, the maxillary sinus floor bone (9) reaches the position of the maxillary sinus floor bone (10).
その後、骨補填材(12)を補填する。 Thereafter, the bone filling material (12) is filled.
しかし、槌打部(18)を槌打する加減は、術者の経験と感に頼らざるを得ず、上顎洞粘膜(11)を突き破ることがあるという問題があった。 However, the adjustment of striking the striking portion (18) has to rely on the experience and feeling of the surgeon, and there is a problem that the maxillary sinus mucosa (11) may be breached.
また、上顎骨(13)が骨折に到らず、槌打しただけの時の手の感覚と、上顎骨(13)が円形に貫通するように骨折する瞬間の手の感覚との間には、大きな差異がなく、そのため、槌打部(18)を通じて感じる槌打感に生じる変化が、術者には察知し辛いという問題があった。 In addition, there is a gap between the sensation of the hand when the maxilla (13) does not reach a fracture and it is just beaten, and the sensation of the hand when the maxilla (13) fractures so that it penetrates in a circle. There was no big difference, and therefore, there was a problem that it was difficult for the surgeon to detect the change that occurred in the hit feeling felt through the hit portion (18).
以上のように、上顎洞底挙上術の施術には、多大な時間が必要であり、術者に高度な技術が要求されていた。 As described above, the operation of the maxillary sinus floor raising operation requires a great deal of time, and a high level of skill is required of the operator.
本発明の目的は、上顎臼歯部の歯牙欠損時に歯牙再生術を行なうため、上顎臼歯部に人工歯根を埋入する際の上顎洞底挙上術において、上顎洞底骨の骨折挙上の安全性および確実性の向上により、歯牙再生治癒期間の短縮化を可能とする上顎洞底挙上術用器具を提供することにある。 The object of the present invention is to perform tooth regeneration when a tooth is missing in the maxillary molar part. Therefore, in the maxillary sinus floor raising operation when an artificial root is embedded in the maxillary molar part, It is an object of the present invention to provide a maxillary sinus floor elevation device that can shorten the period of tooth regeneration and healing by improving the reliability and reliability.
本発明の上顎洞底挙上術に用いる施術用器具は、取手と先端部を有し、該取手の端部に設けられた槌打部を槌打することにより、該先端部により骨が円形に貫通するように骨折させる施術に用いる施術用器具であり、前記槌打部に開口し、該取手の軸方向に伸長する共鳴用穴を備える。 The surgical instrument for use in the maxillary sinus floor elevation operation of the present invention has a handle and a distal end, and the bone is rounded by the distal end by striking the striking portion provided at the end of the handle. This is a surgical instrument used for a surgical operation that fractures the bone so as to penetrate through, and includes a resonance hole that opens in the striking portion and extends in the axial direction of the handle.
さらに、前記共鳴用穴の軸方向に垂直な断面の形状が、円、楕円または多角形であることが望ましい。 Furthermore, it is desirable that the shape of the cross section perpendicular to the axial direction of the resonance hole is a circle, an ellipse or a polygon.
さらに、前記共鳴用穴の軸方向に垂直な断面の形状が、異なる深さで、同じか、または異なることが望ましい。 Furthermore, it is desirable that the shape of the cross section perpendicular to the axial direction of the resonance hole is the same or different at different depths.
さらに、前記共鳴用穴の軸方向に垂直な断面の形状が、異なる深さで、相似的に異なることが望ましい。 Furthermore, it is desirable that the shape of the cross section perpendicular to the axial direction of the resonance hole is similar at different depths.
さらに、前記共鳴用穴の内側面は、直線を回転軸とする回転面であるか、または、任意に傾斜する曲面であることが望ましい。 Furthermore, it is desirable that the inner surface of the resonance hole is a rotating surface having a straight line as a rotation axis, or a curved surface that is arbitrarily inclined.
さらに、前記共鳴用穴が、複数であることが望ましい。 Furthermore, it is desirable that there are a plurality of resonance holes.
なお、本発明は、上顎洞底挙上術、および骨が円形に貫通するように骨折させる整形分野の施術用器具に適用することが可能である。 Note that the present invention can be applied to maxillary sinus bottom elevation and surgical instruments in the orthopedic field in which bone fractures so that the bone penetrates in a circular shape.

本発明について、図面を参照して、説明する。 The present invention will be described with reference to the drawings.
図1は、本発明の上顎洞底挙上術用器具の一実施例を示す一部破断斜視図である。 FIG. 1 is a partially broken perspective view showing an embodiment of the maxillary sinus floor elevation device of the present invention.
本発明の上顎洞底挙上術用器具は、器具先端部(1)から、屈曲部(2)および屈曲部(3)を経由し、端部が平面形状あるいは球面形状である槌打部(6)が設けられた器具取手(4)までが一体に構成される。槌打部(6)には、槌打時の槌打音を反響させるために、槌打する部分に開口する共鳴用穴(5)を開けている。また、屈曲部(2)および屈曲部(3)を設けずに、器具先端部(1)から器具取手(4)までが、直線状に構成されたり、あるいは湾曲状に構成されていても構わない。 The maxillary sinus floor elevation surgical instrument of the present invention is a striking part having a planar shape or a spherical shape at the end part from the instrument tip part (1) via the bent part (2) and the bent part (3). Up to the instrument handle (4) provided with 6) is integrally formed. The hitting portion (6) is provided with a resonance hole (5) opened in a hitting portion in order to resonate the hitting sound at the time of hitting. Further, without providing the bent portion (2) and the bent portion (3), the instrument tip (1) to the instrument handle (4) may be configured linearly or curvedly. Absent.
また、器具取手(4)の材質は、周知の金属、合金および合成樹脂などから選択すればよく、例えば、チタンまたはチタン合金を例示することができる。 Moreover, what is necessary is just to select the material of an instrument handle (4) from a well-known metal, an alloy, a synthetic resin, etc., For example, titanium or a titanium alloy can be illustrated.
さらに、共鳴用穴(5)の軸方向に垂直な断面の形状は、円、楕円または多角形としたり、異なる深さで、同じか、または異なっていたり、異なる深さで、相似的に異なるように、本発明の主旨内で変化させることができる。さらに、前記共鳴用穴(5)の内側面は、直線を回転軸とする回転面であるか、または、任意に傾斜する曲面としてもよいし、共鳴用穴(5)が、複数であってもよい。したがって、発せられる音の変化が識別しやすいように、共鳴用穴(5)の形状および数を決定する。 Further, the shape of the cross section perpendicular to the axial direction of the resonance hole (5) may be a circle, an ellipse, or a polygon, or may be the same or different at different depths, or may be different at different depths. Thus, it can be changed within the gist of the present invention. Further, the inner side surface of the resonance hole (5) may be a rotation surface having a straight line as a rotation axis, or may be a curved surface that is arbitrarily inclined, and there are a plurality of resonance holes (5). Also good. Therefore, the shape and the number of the resonance holes (5) are determined so that the change in the emitted sound can be easily identified.
本発明の上顎洞底挙上術用器具を使用して行う上顎洞底挙上術の施術時には、従来と同様、図2に示すように、上顎骨(13)に対して人口歯根床(8)を穿孔し、上顎洞底骨(9)を薄く残した状態とする。その後、人口歯根床(8)に器具先端部(1)を挿入し、槌打部(6)を、図示しない槌にて槌打することにより、上顎骨(13)が円形に貫通するように骨折させて、上顎洞粘膜(11)と共に上顎洞(16)内への挙上を行なう。従って、上顎洞底骨(9)は、上顎洞底骨(10)の位置に到る。 When performing maxillary sinus floor elevation using the instrument for maxillary sinus floor elevation of the present invention, as shown in FIG. 2, the artificial tooth root bed (8) with respect to the maxilla (13) as shown in FIG. ), And the maxillary sinus floor bone (9) is left thin. Thereafter, the instrument tip (1) is inserted into the artificial tooth root bed (8), and the striking portion (6) is beaten with a scissors (not shown) so that the maxilla (13) penetrates circularly. The bone is broken and raised into the maxillary sinus (16) together with the maxillary sinus mucosa (11). Therefore, the maxillary sinus floor bone (9) reaches the position of the maxillary sinus floor bone (10).
その後、骨補填材(12)を補填する。 Thereafter, the bone filling material (12) is filled.
したがって、上顎骨(13)が骨折に到らず、槌打しただけの時の共鳴用穴(5)から発せられる音と、上顎骨(13)が円形に貫通するように骨折する瞬間に共鳴用穴(5)から発せられる音との間に、明確な差異が生じ、このような音の変化により、上顎骨(13)が骨折した瞬間に、槌打を終了することが容易となる。 Therefore, the maxillary bone (13) does not reach a fracture and resonates at the moment when the fracture occurs so that the maxillary bone (13) penetrates in a circle and the sound emitted from the resonance hole (5) when it is just beaten. There is a clear difference between the sound emitted from the working hole (5), and such a change in sound makes it easy to end the striking at the moment when the maxilla (13) breaks.
また、本発明は、上顎洞底挙上術以外にも、骨を円形に貫通することにより骨折させる施術に利用することが可能であり、例えば整形の分野における施術にも適用することが可能である。 In addition to the maxillary sinus floor elevation, the present invention can be used for a surgical operation in which a bone is fractured by penetrating the bone in a circular shape. For example, the present invention can be applied to a surgical operation in the field of orthopedics. is there.
