Tooth agenesis is one of the most common congenital anomalies seen in humans. Although absence of one or more teeth is common but absence of multiple teeth is rare. Oligodontia is a rare developmental anomaly, involving agenesis of six or more permanent teeth, excluding the third molars. The reported prevalence of oligodontia in permanent dentition is 0.14%. Oligodontia can present as an isolated condition or as a part of a syndrome. The present case report highlights a unique case of non syndromic oligodontia, with agenesis of four permanent incisors, left permanent canine and right second premolar in the mandibular arch and its management with a novel fixed functional prosthetic appliance. Prosthetic rehabilitation is an urgent need for these kind of patients so that they do not suffer from masticatory and esthetic problems which can eventually lower the self esteem of individuals.
牙齿发育不全是人类最常见的先天性异常之一。虽然一颗或多颗牙齿缺失很常见，但多颗牙齿缺失却很罕见。少牙畸形是一种罕见的发育异常，涉及六颗或更多恒牙的发育不全，不包括第三磨牙。报道的恒牙列少牙畸形患病率为0.14%。少牙畸形可表现为孤立病症或作为综合征的一部分。本病例报告突出了一例非综合征性少牙畸形的独特病例，下颌牙弓中四颗恒切牙、左侧恒尖牙和右侧第二前磨牙发育不全，并采用新型固定功能性修复装置进行治疗。对于这类患者来说，修复性康复是迫切需要的，这样他们就不会遭受咀嚼和美观问题，而这些问题最终可能会降低个人的自尊心。
