Description

本発明は、顎骨にインプラント体を植立する際に、顎骨に設けられたインプラント植立孔とインプラント体との隙間に補填するために使用する骨片を、インプラント植立孔をあける作業と同時に収集する歯科用骨収集装置に関する。   In the present invention, when implanting an implant body in a jawbone, a bone fragment used to make up for a gap between the implant implantation hole provided in the jawbone and the implant body is simultaneously formed with the operation of opening the implant implantation hole. The present invention relates to a dental bone collecting device for collecting.

歯科治療において、顎骨にインプラントを植立する際、まず、顎骨である歯槽骨をインプラント体に合わせてドリルで拡張穿孔し、設けられたインプラント植立孔にインプラント体を挿入する。この際、かかる植立孔とインプラント体に隙間が生ずる場合があるため、これを補填する必要がある。かかる補填には、骨片を利用できる。   In dental treatment, when implanting an implant in a jawbone, first, an alveolar bone, which is a jawbone, is expanded and drilled with a drill in accordance with the implant body, and the implant body is inserted into the provided implant placement hole. At this time, there may be a gap between the planting hole and the implant body, and it is necessary to compensate for this. Bone fragments can be used for such compensation.

従来、骨片を収集する装置としては、トレフィンバー、コレクバー、Ｋトレフィンバー、特開２００７−２２９４６５号公報に記載されたようなボーンスクレイパー、または特表平１１−５１４９０５号公報、特表平１０−５０５７７５号公報に記載されているようなボーンコレクターなどが市販されている。   Conventionally, as a device for collecting bone fragments, trefin bar, collect bar, K trephine bar, bone scraper as described in JP-A-2007-229465, or JP 11-514905 A, JP 10 flat Bone collectors such as those described in JP-A-505775 are commercially available.

一方、上記の顎骨にドリルでインプラント植立孔を拡張穿孔する際に、骨片が生じるが、従来ほとんどの場合、かかる骨片は廃棄されていた。   On the other hand, when the above-mentioned jaw bone is expanded and drilled with an implant planting hole, a bone fragment is generated. In most cases, such a bone fragment has been discarded.

近年、かかる歯科治療において、顎骨にインプラント植立孔をあける際に生ずる骨片を収集する試みがなされている。このような骨収集装置として、例えば、特開平１０−１１８０８５号公報に、ドリルを囲む管の中に骨を収集する装置が記載され、特開２００４−３２９３１２号公報および特開２００５−１３７４２７号公報に、吸入することにより骨を収集する装置が記載されている。   In recent years, in such dental treatment, attempts have been made to collect bone fragments generated when an implant placement hole is drilled in the jawbone. As such a bone collecting device, for example, Japanese Patent Application Laid-Open No. 10-118085 describes a device for collecting bone in a tube surrounding a drill, and Japanese Patent Application Laid-Open No. 2004-329312 and Japanese Patent Application Laid-Open No. 2005-137427. Describes a device for collecting bone by inhalation.

しかし、特開平１０−１１８０８５号公報に記載されているような装置では、装置から骨片を収集しにくく、骨片が残留すると次の機会に収集する骨片が汚染されるという問題がある。また、特開２００４−３２９３１２号公報および特開２００５−１３７４２７号公報に記載されているような装置では、口腔内の不純物および汚染物が混入するという問題がある。また、吸入後に骨片を選別するために使用されるフィルターの洗浄が困難であり、前述と同様に汚染機会が増えるという問題もある。
特開２００７−２２９４６５号公報 特表平１１−５１４９０５号公報 特表平１０−５０５７７５号公報 特開平１０−１１８０８５号公報 特開２００４−３２９３１２号公報 特開２００５−１３７４２７号公報 However, the apparatus described in Japanese Patent Laid-Open No. 10-118085 has a problem that it is difficult to collect bone fragments from the apparatus, and if the bone fragments remain, the collected bone fragments are contaminated at the next opportunity. In addition, the devices described in Japanese Patent Application Laid-Open Nos. 2004-329312 and 2005-137427 have a problem that impurities and contaminants in the oral cavity are mixed. In addition, it is difficult to clean a filter used for sorting bone fragments after inhalation, and there is a problem that the chance of contamination increases as described above.
