Description
【０００１】[0001]
この考案は、被検者に各種条件で咀嚼咬合させ下顎５点の位置関係及び咀嚼咬 合運動を下顎運動シュミレーション測定センサーで測定し、下顎運動シュミレー ション測定用コンピューターで解析演算させ必要な数値データー、及び下顎５点 の運動軌跡を下顎運動シュミレーション測定ディスプレーに表示する医療用測定 機、下顎運動シュミレーション測定機です。 This invention is to make the subject masticate and bite under various conditions, measure the positional relationship of the 5 points of the lower jaw and the masticatory occlusal movement with the lower jaw movement simulation measurement sensor, and analyze and calculate the lower jaw movement simulation computer to obtain the necessary numerical data. This is a medical measurement device that displays the movement loci of the lower jaw and 5 points of the lower jaw on the lower jaw movement simulation measurement display.

従来、下顎の運動を左右下顎中切歯間の１点で３次元的に測定しシュミレーシ ョンする歯科用測定機が使用されています。 Conventionally, a dental measuring machine has been used that three-dimensionally measures the movement of the lower jaw at one point between the left and right lower central incisors and simulates it.
【０００３】[0003]
【考案が解決しようとする課題】 従来、使用されている１点３次元下顎運動歯科用測定機は、測定用センサ ー部の重量に比較して頭蓋固定装置の固定力が弱く、また咀嚼運動測定時に 咬合筋群の影響を受け不安定であり測定用センサーを目的の位置に固定する のが困難です。 従来、使用されている１点３次元下顎運動歯科用測定機は、歯科医学的に 最も必要な下顎の咀嚼咬合運動測定において、左右下顎関節頭の位置関係及 び精密な下顎運動軌跡測定が出来ない。 上記の歯科医学的に重要な測定が不十分なため、口腔内補綴物、骨内 人工歯根補綴物等の適合性診断等の歯科臨床診断が十分に行えない。 不適合口腔内補綴物装着による上下顎歯槽骨の垂直吸収型歯周病、及び下 顎関節疼痛等、咀嚼咬合時の過重負担が原因で発生する障害の予見診断が充 分出来ない。 従来、使用されている１点３次元下顎運動歯科用測定機は、検知用の永久 磁石の検知面積が広く、またセンサー検知能力、測定値オーダーが大きく微 細な変位に対しコンピューター解析負荷が過重になり微細測定値に誤差がで やすい。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the conventional one-point three-dimensional mandibular movement dental measuring instrument used, the fixing force of the skull fixing device is weak compared with the weight of the measuring sensor part, and the masticatory movement is performed. During measurement, it is unstable due to the influence of the occlusal muscle group and it is difficult to fix the measurement sensor at the target position. The conventional one-point three-dimensional mandibular movement dental measuring instrument used in the past is capable of measuring the positional relationship of the left and right mandibular condyle joints and precise mandibular movement trajectory in the measurement of the masticatory occlusal movement of the mandible, which is the most necessary for dentistry. Absent. Since the above-mentioned dentally important measurement is insufficient, dental clinical diagnosis such as compatibility diagnosis of an intraoral prosthesis, an intraosseous artificial root prosthesis and the like cannot be sufficiently performed. Predictive diagnosis of disorders caused by overloading during masticatory occlusion, such as vertical resorption periodontal disease of the upper and lower alveolar bones due to incompatible oral prosthesis attachment, and mandibular joint pain, etc. is not possible. Conventionally, the one-point three-dimensional mandibular movement dental measuring instrument that has been used has a wide detection area of a permanent magnet for detection, a large sensor detection capability, a large order of measured values, and an excessive computer analysis load for minute displacements. Therefore, the error is likely to occur in the fine measurement value.
