Teeth, either erupted or impacted, that exceed the normal count are known as supernumerary teeth. They can appear unilaterally or bilaterally, singly or in multiples, and may be located anywhere in both dental arches. Multiple permanent impacted supernumerary teeth are uncommon and are often associated to syndromes but can be idiopathic. The prevalence of nonsyndromic multiple supernumerary teeth is under 1%. Here, we present a rare case of nonsyndromic multiple supernumerary and permanent impacted teeth in a young female patient, who reported with no loss of deciduous teeth and no eruption of permanent teeth except the first maxillary and mandibular permanent molars. A panoramic radiograph showed several supernumerary and permanent impacted teeth in both maxillary and mandibular arches. The diagnosis of idiopathic hyperdontia was made on the basis of clinical features and radiographic examination, and the management strategy needs to be planned with a multidisciplinary approach.
数目超过正常的已萌出或阻生牙被称为多生牙。它们可单侧或双侧出现，单个或多个出现，并且可能位于上下牙弓的任何位置。多个恒牙阻生多生牙并不常见，常与综合征相关，但也可能是特发性的。非综合征性多个多生牙的患病率低于1%。在此，我们报告一例年轻女性患者罕见的非综合征性多个多生牙及恒牙阻生病例，该患者乳牙未脱落，除上颌和下颌第一恒磨牙外恒牙未萌出。全景X线片显示上颌和下颌牙弓均有多个多生牙及恒牙阻生。根据临床特征和影像学检查做出特发性多生牙的诊断，并且需要采用多学科方法来制定治疗策略。
