口腔治疗中前牙区美学的考量因素

前牙区是口腔美学治疗的关键,前牙形态和位置的调整是系统性美学治疗的重要部分。临床诊疗中,口腔期望恢复天然牙形态使之与面型协调;关闭前牙间隙、调整中线位置使弓形美观、对称;通过垂直向和水平向控制使牙列与龈、颊组织关系协调,展现美丽微笑。完善的前牙美学治疗需要多学科联合、多种治疗方法介入,同时应考虑患者的文化背景和审美习惯,以实现最佳治疗效果。数字化诊疗技术为治疗前美学分析预测、治疗后美学评估提供了保障。该文结合国内外最新研究成果,从前牙位置、形态以及牙列与龈、颊等软组织关系等方面对口腔治疗中前牙美学考量因素作一综述,为美学区口腔治疗规划提供参考。

Aesthetic considerations of anterior zone in oral treatment

The anterior zone is critical for oral aesthetic therapy, and adjusting the shape and position of anterior teeth is an important part of systematic aesthetic therapy. In clinical diagnosis and treatment, the dentist expects to restore natural teeth shape to coordinate with facia shape; to close anterior tooth space and adjust midline position to make the bow beautiful and symmetrical; to coordinate the relationship between dental arch and gingival and buccal tissue through vertical and horizontal control to achieve a beautiful smile. Perfect aesthetic treatment of anterior teeth requires the intervention of multi-disciplines and multiple treatment methods, and cultural background and aesthetic habits of patients should be regarded to achieve the best treatment effect. Digital diagnosis and treatment technology provides a guarantee for pre-treatment aesthetic analysis and prediction and post-treatment aesthetic evaluation. Based on the latest research at home and abroad, in this paper, both the anterior teeth’s position and shape and the relationship between dentition and gingival, buccal soft tissue are considered to summarize aesthetic considerations of anterior zone in oral treatment, so as to provide reference for oral treatment planning in aesthetic zone.
