种植义齿有着传统义齿所无法迄及的功能和美学修复效果,享有“人类的第三副牙齿的美誉”。它的美观和功能优于传统义齿,不仅咀嚼效率高,不损伤邻牙,而且还能有效防止颌骨萎缩吸收,日益成为缺牙修复的趋势~([1,2])。种植牙的成功率主要取决于种植区有充足的基础骨量,保证种植体与骨组织之间形成骨结合。研究表明,种植体周围至少需要1mm的骨量才能保证植入种植体的稳定性~([3]),目前,临床上常用于牙槽嵴增宽的技术主要是骨劈开术和onlay植骨
Dental prosthesis with the traditional dentures can not reach the function and aesthetic repair effect, enjoy the “third human teeth reputation.” Its aesthetic appearance and function are superior to the traditional dentures. It not only has high chewing efficiency, does not damage the adjacent teeth, but also effectively prevents jaw atrophy and absorbs, and is increasingly becoming the trend of the restoration of the missing teeth ([1,2]). The success rate of dental implants depends mainly on the sufficient amount of basic bone mass in the area of implants to ensure osseointegration between the implants and the bone tissue. Studies have shown that at least 1mm bone mass around the implant is needed to ensure the stability of the implants (3). At present, the most commonly used techniques for alveolar ridge augmentation in clinic are osteoporosis and onlay bone
