The prosthetic treatment of patients with total maxillectomies is an enormous reconstruction challenge because of insufficient support and retention from the residual tissues. It is not possible to place the bulb in the presence of unfavorable undercuts throughout the nasal cavity floor and borders. The purpose of this article was to describe a prosthetic reconstruction technique which accomplishes optimum sealing, retention, stabilization, and easy placement of an open-hollow acrylic resin obturator using a spring with a resilient liner for a patient who underwent a total maxillectomy. The springs were placed in the resilient liner to facilitate the placement of the obturator prosthesis because of unfavorable undercuts. It was possible to fit the prosthesis in two stages by means of springs. The objective of this technique is to improve the patient's psychological, functional, and social well-being by producing a stable, retentive, leakproof, comfortable, easy-fitting prosthesis. This technique is appropriate for patients who have undergone total maxillectomies when implant placement is not possible.
由于残余组织提供的支持和固位不足,全上颌骨切除患者的修复治疗是一项巨大的重建挑战。当鼻腔底部和边缘存在不利倒凹时,无法放置球状物。本文的目的是描述一种修复重建技术,该技术使用带有弹性衬垫的弹簧,为一名接受全上颌骨切除的患者实现开放式中空丙烯酸树脂阻塞器的最佳密封、固位、稳定和轻松放置。由于存在不利倒凹,将弹簧置于弹性衬垫中以方便阻塞器假体的放置。借助弹簧分两个阶段安装假体是可行的。该技术的目标是通过制作一个稳定、固位、防漏、舒适且易于安装的假体,改善患者的心理、功能和社会福祉。当无法植入种植体时,该技术适用于接受全上颌骨切除的患者。
