Delayed development and eruption of all the permanent molars is a rare phenomenon, which can cause disturbance in the developing occlusion. The eruption of permanent first and second molars is very important for the coordination of facial growth and for providing sufficient occlusal support for undisturbed mastication. In the case described, the first permanent molars were delayed in their development and were seen erupting at the age of nine and a half years. Severe disparity between the left and the right side of the dentition with respect to the rate of development of molars were also present.
所有恒牙磨牙的发育和萌出延迟是一种罕见的现象，这可能会导致正在发育的咬合关系紊乱。第一恒磨牙和第二恒磨牙的萌出对于面部生长的协调以及为正常咀嚼提供足够的咬合支持非常重要。在所述病例中，第一恒磨牙发育延迟，在九岁半时才开始萌出。牙列的左右两侧在磨牙发育速度方面也存在严重差异。
