Abstract

Materials and methods: In this in vitro study, 13 extracted intact maxillary second molars were mounted 1 mm lower than the CEJ and the appropriate crown size was selected from the 3M and MIB brands. Preparation of the teeth for ssc was performed by a pediatric dentist. Sufficient seating and retention of the crowns were evaluated. The photographs of crown margins were taken by a digital camera and crown circumference measured with the Auto Cad software. Then, the ZWICK machine measured the force required to place each of the crowns on the tooth. Using the proportionality between the measured force and the circumference of the margin of each crown, the level of force equilibrated in each crown was obtained and compared.
两种不同的不锈钢冠(3M和MIB)在第一磨牙上的灵活性比较
材料和方法:在体外研究中,13颗拔出的完整上颌第二磨牙比CEJ低1mm,从3M和MIB品牌中选择合适的冠尺寸。为ssc准备牙齿由儿科牙医进行。评估冠的充分就位和固位。用数码相机拍摄冠缘,用Auto Cad软件测量冠围。然后,ZWICK机器测量了将每个冠放在牙齿上所需的力。利用测得的力与各牙冠边缘周长之间的比例关系,得到各牙冠内的平衡力水平并进行比较。
