Congenitally missing teeth are not an unusual occurrence. What makes this case study unique is the combination of restorative challenges offered. The patient presented with the permanent upper right cuspid and lower anterior right and left central incisors congenitally missing, and with an underdeveloped upper right lateral incisor. Distinctive existing occlusion and tooth alignment difficulties precluded a simple approach of merely extracting the residual primary teeth and replacing the missing teeth prosthetically. Using orthodontics to create ideal interocclusal and interarch space was critical in preparing this case for prosthetic restoration.
先天性缺牙并非罕见情况。本病例研究的独特之处在于所呈现的修复挑战的组合。该患者先天性缺失右上恒尖牙以及右下和左下前牙区的中切牙,且右上侧切牙发育不全。现有的独特咬合关系和牙齿排列困难使得仅仅拔除残留乳牙并进行假牙修复的简单方法不可行。利用正畸手段创造理想的牙合间和牙弓间间隙对于为该病例进行假牙修复准备至关重要。
