Abstract:
This clinical report presents a unique and previously unreported case of anatomical variations in the mandible, specifically involving the main mental foramen (MF), the mandibular canal (MC), and genial tubercles (GTs). The case involves a 21-year-old male seeking dental implant rehabilitation. The patient exhibited an unusual lingual exit path of the main left MF through the lingual cortical bone, with the MC following an anterior lingual direction along a lingual groove before exiting through the labial cortical bone between the apexes of the left canine and first premolar. Additionally, the patient displayed excessive enlargement and rare shape of the GTs. These rare anatomical findings presented challenges in dental implant planning. This case report emphasizes the importance of advanced imaging techniques like cone-beam computed tomography (CBCT) in evaluating mandibular structures for precise treatment planning and highlights the significance of understanding anatomical variations to prevent complications in dental procedures.
摘要:
本临床报告提供了一个独特的和以前未报告的下颌骨解剖变异的病例,特别涉及主要精神孔(MF),下颌管(MC),和生殖器结节(GTs)。此案涉及一名21岁的男性寻求牙科植入物康复。患者表现出通过舌皮质骨的主要左MF的异常舌出口路径,MC沿着舌沟沿舌前方向,然后通过左犬和第一前磨牙的顶点之间的唇皮质骨离开。此外,患者表现出GTs的过度放大和罕见的形状。这些罕见的解剖学发现在牙种植计划中提出了挑战。该病例报告强调了诸如锥形束计算机断层扫描(CBCT)之类的先进成像技术在评估下颌结构以进行精确治疗计划方面的重要性,并强调了理解解剖学变化以防止牙科手术并发症的重要性。
