The severely resorbed maxilla presents a challenge for the maxillofacial surgeon and the restorative dentist planning implant restorations. The Zygomatic implant, as introduced by Brånemark, allows for the surgical placement of implants to restore resorbed maxillae without major grafting procedures. A minimum of 2 implants in the anterior maxilla are used in conjunction with 1 implant in each zygoma to support a prosthesis. Fabricating a passive bar to connect the implants at phase II surgery may require 1 to 2 days. With the adhesive abutment cylinder luting technique, a rigid framework can be delivered within 1 hour of uncovering the implants. This approach saves considerable time over conventional techniques and allows for the restoration of severely resorbed maxillae in an efficient and routine manner. The technique also eliminates the necessity for a technician to be available on-site for the procedure.
严重吸收的上颌骨给颌面外科医生和计划进行种植修复的修复牙医带来了挑战。由布兰emark引入的颧骨种植体,允许通过手术植入种植体来修复吸收的上颌骨,而无需进行大型植骨手术。在上颌前部至少使用2枚种植体,并在每侧颧骨各使用1枚种植体来支持假体。在二期手术中制作连接种植体的被动杆可能需要1至2天。采用粘结基台圆柱体粘结技术,在暴露种植体后1小时内即可交付刚性框架。这种方法比传统技术节省了大量时间,并能以高效且常规的方式修复严重吸收的上颌骨。该技术还消除了术中需要技术人员现场协助的必要性。
