Maxillary defects, whether congenital or acquired, make a patient encounter an array of physical and psychological difficulties, leading to an extremely poor quality of life. Rehabilitation of such a patient is often challenging due to the extent of the defect area coupled with the absence of adequate retention caused by the size and weight of the prosthesis. Further, providing a proper seal of the oronasal communication is of utmost importance to restore function. Taking the above factors into consideration, a combination of hollow-bulb obturator consisting of a titanium framework and a flexible, snap-on silicone cap is an effective prosthesis providing a long-term treatment, increased retention, and a happy patient. The fabrication protocol included the use of computer-aided design, titanium along with laser welding, and an intraoral trial before final fabrication, hence, reconfirming the success of the prosthetic design. The maxillary obturator presented in this article eliminates several disadvantages associated with a conventional hollow-bulb obturator, thereby providing a novel, viable option for a maxillofacial prosthodontist.
上颌骨缺损,无论是先天性的还是后天获得性的,都会使患者面临一系列身体和心理上的困难,导致生活质量极差。由于缺损区域范围较大,加上假体的尺寸和重量导致缺乏足够的固位力,对这类患者进行修复往往具有挑战性。此外,对口鼻相通处进行适当封闭对于恢复功能至关重要。考虑到上述因素,一种由钛框架和灵活的卡扣式硅胶帽组成的空心球阻塞器组合是一种有效的假体,可提供长期治疗、增强固位力,并让患者满意。制作方案包括使用计算机辅助设计、钛以及激光焊接,并在最终制作前进行口内试戴,因此再次证实了假体设计的成功。本文介绍的上颌阻塞器消除了与传统空心球阻塞器相关的几个缺点,从而为颌面修复医生提供了一种新颖、可行的选择。
