近年来无牙颌种植支持式固定义齿的应用得到了极大的普及。但是由于受到上颌骨的解剖形态、上颌骨吸收形式、种植区牙槽骨的质量、上颌骨在发音中的重要作用、上前牙在面部美学中的重要作用等因素的影响。因此，医生在进行上颌无牙颌种植支持式固定义齿的诊断和设计时需要非常谨慎。本文回顾了近年来关于上颌无牙颌种植支持式固定义齿牙颌面部美学诊断、设计的文章，通过对牙颌面部进行垂直向美学分析，为需要进行上颌无牙颌种植支持式固定义齿修复的患者提供美学设计基础。

Analysis of esthetic parameters in superior-inferior analysis for implant-supported fixed prosthesis in the edentulous maxilla

Fixed implant-supported prosthesis for the edentulous maxilla has gained tremendous popularity over these years. However, fixed prosthetic rehabilitation of the edentulous maxilla is known to be challenging and requires meticulous planning. This is mainly due to the natural anatomy of the maxilla, the pattern of bone resorption, quality of bone for implant placement, development of prosthetic emergence profile, oral hygiene issues, role of the teeth and hard tissue in speech, and the importance of the prosthesis on facial and dental esthetics. This article reviews pertinent dental and facial esthetics literature for application of various esthetic concepts involved in diagnosis and treatment planning for an implant-supported fixed prosthesis in the edentulous maxilla. Analysis of esthetic parameters in superior-inferior analysis can help the clinician lay the foundation for esthetic diagnostics of maxillary implant-supported fixed prostheses.
