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.

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.
