研究目的:

牙槽骨吸收是由于牙齿脱落后局部炎症和长期缺乏生理刺激而发生的。上颌窦的气化更容易导致残余骨高度的严重降低,尤其当残余骨高度不足4mm时,给上颌后牙区种植修复带来了巨大挑战。以往常通过上颌窦外提升并延期种植的方案进行种植治疗。但这种技术会延长恢复时间,给病人带来更多痛苦,此外,当残余骨高度小于1.5mm时只剩下皮质骨,可能无法进行有效的移植物再生。除此之外,颧骨种植体被提出用于上颌后牙区骨量极度不足的情况。该植入物长度约为30~52.5 mm,需穿过窦腔并固定在颧骨上以保持稳定。少数病例显示出该技术的良好效果,但仍缺乏进一步的长期临床观察。同时该技术更具侵入性和复杂性,通常伴有严重的并发症,如感染、出血和神经损伤。鉴于此,本课题开发了一种新型种植体,该植入物由短植入物和固定翼组成。种植体有植入部分和基台结构,保留平台转移的结构特点,确保种植体种植后周围形成软组织闭合。翼板采用钛螺丝固定,设计灵活,提供主要固位。该方法具有创伤小、安全有效等优点,值得临床推广应用。本临床研究的目的是评价此CAD/CAM带翼短种植体在重度萎缩性上颌后区修复中的临床效果。  

Objectives of Study:

Alveolar bone resorption occurs due to local inflammation and a long-time lack of physiological stimulation after tooth loss. Pneumatization of the maxillary sinus is more likely to lead to a severe reduction of residual bone height (RBH). When RBH less than 4mm, it brings a big challenge to implant restoration in the maxillary posterior region. In this case, lateral sinus floor elevation with delayed implant placement is recommended. However, this technique would prolong the recovery time and cause more suffering for patients. Moreover, when the RBH is below 1.5mm, only cortical bone is left, and effective graft regeneration may not be possible. Besides, Zygomatic implants are developed to use when the RBH in the maxillary posterior area is extremely insufficient. This implant is about 30–52.5 mm in length and should be placed via the sinus cavities and anchored in the zygoma for stability. A few cases have shown favorable results for this technique, but further long-term clinical observation is still lacking. In addition, the technique is more invasive and complex, and is often associated with serious complications such as infection, bleeding, and nerve damage. Therefore, it is not widely used in clinics. In view of this, We have developed a new type of implant, This implant is composed of a short implant and retaining wings and the platform switching structure is maintained to ensure soft tissue closure formation around the implant after implantation. The wing retention is fixed by titanium screws, which can be flexibly designed and provide the main fixation. This method is less invasive, and safer and more effective which maybe a satisfactory method for clinical application. The aim of this clinical study was to evaluate the clinical outcomes of the new implants applied in severe atrophic maxillary posterior region restoration.
