In 311 examinees (177 boys and 134 girls) with primary dentition and 535 examinees (285 boys and 250 girls) with mixed dentition in Istria--Croatia, the frequency of orthodontic and occlusal anomalies in regard of space plane and premature extraction of c, m1 and m2 are investigated. The orthodontic anomalies are fortified in 46.95%, premature loss in 11.25% and occlusal anomalies in 40.83% of examinees with primary dentition, while in mixed dentition the 58.69% of examinees have orthodontic anomaly, the 17.20% premature loss and the 48.97% of examinees have occlusal anomaly. In both phases of dentition the most frequent are occlusal anomalies: combination of sagittal-vertical plane, and those in sagittal and vertical space plane respectively.
在伊斯特拉（克罗地亚）的311名乳牙期考生（177名男孩和134名女孩）和535名混合牙列期考生（285名男孩和250名女孩）中，研究了关于间隙平面以及乳尖牙、第一恒磨牙和第二恒磨牙过早拔除方面的正畸和咬合异常的发生率。乳牙期考生中，46.95%存在正畸异常，11.25%存在过早缺失，40.83%存在咬合异常；而在混合牙列期，58.69%的考生存在正畸异常，17.20%存在过早缺失，48.97%的考生存在咬合异常。在牙列的两个阶段中，最常见的是咬合异常：矢状-垂直平面的组合，以及分别在矢状和垂直间隙平面的异常。
