摘要

本研究的目的是评估一个病例中咬合,高发散,开放咬合接触点的数量,强度和位置。使用Planmeca Esmerald S型口内扫描仪在最大间隔时间内对前、外侧开放咬合患者进行咬合记录。使用3shape Ortho Analyzer Orthodontics软件,使用Occlusion Map模块,通过3D Color Map工具,使用0.5 mm的虚拟关节纸,分析咬合接触强度。将这些结果与Planas定义的咬合支撑点进行比较[10]。通过记录过程中3个不同时刻(1S、2S、3S)接触点的咬合强度、接触次数和位置对数据进行解释。彩色地图的色阶是:红、橙、黄、绿、蓝。为了在数字中识别咬合接触点,当完全接触时,它们用红色点表示,而最小接触用蓝色点表示。我们评估了有咬合接触的牙齿数量。人们确定,有适当数量的触点并不意味着它们在正确的位置。此外,该方法在咬合接触的归档和记录保存方面具有可靠性。通过识别咬合支撑点的强度、数量和位置,可以客观地记录咬合间的变化。

Clinical application of digitalization of occlusal contacts with dental scanner
This study aimed to evaluate the number, intensity and position of occlusal contact points in a case of mesiocclusion, hyperdivergence, with open bite. An occlusal record was taken from a patient with anterior and lateral open bite mesiocclusion, using the Planmeca Esmerald S intraoral scanner in maximum intercuspation. The intensity of the occlusal contact was analyzed with the software 3shape Ortho Analyzer Orthodontics, using the Occlusion Map module, through the 3D Color Map tool, with a 0.5 mm virtual articular paper. These results were compared to the occlusal support points defined by Planas [10]. The interpretation of the data obtained was made by assessing the interocclusal intensity of the contact points, number of contacts and position during three different moments (1S, 2S, 3S) in the record taking process. The chromatic scale of the Color Map is: red, orange, yellow, green and blue. To identify the occlusal contact points in digital, they are shown in red points when full contact occurs, while minimum contact is shown in blue. We evaluated the number of teeth with interocclusal contacts. It was determined that having the appropriate number of contacts does not imply that they are in the correct position. In addition, the method suggests reliability in the filing and record keeping of occlusal contacts. By identifying intensity, number and position of the occlusal support point we can objectively record interocclusal alterations.
