Abstract

Guided bone regeneration (GBR) requires a tension-free flap without damaging the collateral circulation in order to secure better surgical outcomes. Topographic knowledge regarding the neurovascular bundles in the posterior aspect of the mandible can prevent complications during lingual flap design. The lingual branch (LB) of the inferior alveolar or maxillary arteries is not sufficiently illustrated or described in the literature. Nevertheless, it has an intimate relationship with the lingual nerve (LN) during ridge augmentation and implant-related posterior mandible surgery. Therefore, this study aimed to clarify the morphology and topography of the LB related to GBR surgeries. In the present human cadaveric study, the LB was analyzed in 12 hemimandibles using latex injection and corrosion casting. Two types of LB were identified based on their origin and course. The LB was found in a common connective tissue sheath close to the LN. The LB assembled several anastomoses on the posterior lingual aspect of the mandible and retromolar area. The LB acted as an anatomical landmark in identifying LN at the posterior lingual aspect of the mandible.

下颌骨后嵴增高术中舌侧支的临床意义:尸体试验研究
引导下骨再生(GBR)要求在不破坏侧支循环的情况下使用无张力皮瓣,以确保更好的手术效果。下颌骨后方神经血管束的地形知识可以防止舌骨瓣设计过程中出现并发症。下牙槽动脉或上颌动脉的舌支(LB)在文献中没有充分的说明或描述。然而,在牙脊增高和下颌后部种植相关手术中,它与舌神经(LN)有着密切的关系。因此,本研究旨在阐明与 GBR 手术相关的 LB 的形态和地形。在本人体尸体研究中,使用乳胶注射和腐蚀铸造法分析了 12 个半下颌的枸橼酸钙。根据枸橼酸钙的来源和过程,确定了两种类型的枸橼酸钙。枸橼酸枸橼酸枸橼酸枸橼酸是在靠近枸橼酸结节的一个普通结缔组织鞘中发现的。枸橼酸瘤在下颌骨舌后侧和后磨牙区汇集了多个吻合口。LB 是下颌骨舌后侧识别 LN 的解剖标志。

期刊介绍: The International Journal of Periodontics & Restorative Dentistry will publish manuscripts concerned with all aspects of clinical periodontology, restorative dentistry, and implantology. This includes pertinent research as well as clinical methodology (their interdependence and relationship should be addressed where applicable); proceedings of relevant symposia or conferences; and quality review papers. Original manuscripts are considered for publication on the condition that they have not been published or submitted for publication elsewhere.
