The soft tissue outcome of the projection at the level of the nasomaxillary buttress is difficult to manage in cases of severe hypoprojection, being orthognathic surgery resolutive at the occlusal level but sometimes insufficient at the level of esthetic outcome. The literature describes the use of alloplastic prostheses and autologous bone grafts, but there are few documented cases of the use of premolded surgical cement for this purpose. The main advantage of the use of bone cement over the alternatives described is its ability to be premolded for customization, low cost, easy availability, speed of preparation and minimal comorbidity. This technical note describes the surgical steps and outcome of the use of surgical bone cement for projection augmentation at this level, including notes on preparation, premolding and fixation.

在严重鼻上颌支柱水平投影不足的病例中，软组织的治疗效果很难处理，正颌手术在咬合水平上可以解决问题，但在美学效果水平上有时并不充分。文献中描述了使用异体植入物和自体骨移植，但很少有关于使用预成型外科骨水泥用于此目的的记录案例。与所述替代方法相比，使用骨水泥的主要优点是能够预成型以进行定制、成本低、易于获取、制备速度快且并发症最少。本技术说明描述了在此水平使用外科骨水泥进行投影增强的手术步骤和结果，包括关于制备、预成型和固定的说明。正颌手术、上颌手术、外科骨水泥、鼻上颌支柱。
