Mimetic muscles contract and pull the overlying skin toward the muscle's bony attachment. Numerous books and articles have shown the mimetic muscles via cadaveric dissection. However, for dentistry and oral surgery, the mimetic muscles have not been detailed from intraoral dissection. Recently, several papers have addressed various mimetic muscles in relation to intraoral dissection. However, to our knowledge, there has been no overview of these muscles beneath the oral mucosa. Here, we review the literature concerning the mimetic muscles as revealed during intraoral dissection, create novel illustrations, and discuss the relationship of these muscles with general dentistry and oral surgery. The mimetic muscles, which constitute the surface of the oral mucosa, the relationship of the labial and buccal frenulum and mimetic muscles, the relationship of the mucogingival junction and mimetic muscles, and other surgical procedures are discussed. A better understanding of the mimetic muscles from an intraoral perspective is important for those performing oral surgery and dentistry.
表情肌收缩并将覆盖其上的皮肤拉向肌肉的骨性附着点。众多书籍和文章已通过尸体解剖展示了表情肌。然而，对于牙科和口腔外科而言，尚未从口内解剖的角度详细介绍表情肌。最近，有几篇论文探讨了与口内解剖相关的各种表情肌。然而，据我们所知，尚无关于口腔黏膜下这些肌肉的概述。在此，我们回顾有关口内解剖中所揭示的表情肌的文献，绘制新的插图，并讨论这些肌肉与普通牙科和口腔外科的关系。本文讨论了构成口腔黏膜表面的表情肌、唇颊系带与表情肌的关系、黏膜牙龈交界与表情肌的关系以及其他外科手术。从口内角度更好地了解表情肌对于从事口腔外科和牙科工作的人员而言非常重要。
