种植盾构术的研究进展

上前牙美学区在拔牙或即刻种植后,唇侧骨板因拔牙创伤或者血运降低,常发生唇侧牙槽骨的吸收塌陷,从而极大的影响前牙区的美学效果,甚至造成种植体的失败。为了避免唇侧软硬组织的吸收,获得更好的美学效果,近年来有学者提出了"盾构术"的概念,即在即刻种植手术中通过保留唇侧健康牙根片来保留牙周膜,从而避免唇侧骨板因为血运的减少而发生吸收。本文回顾了盾构术的相关文章,能帮助口腔临床医生更加全面的理解该技术。

Research progress on socket shield technique concurrent with immediate implantation

During tooth extraction, the periodontal ligament, which is responsible for the formation of buccal bundle bone, is lost. Consequently, the blood supply to the bundle bone is discontinued, thereby affecting its nourishment and eventually causing its total or partial resorption. The retained root fragment preserves the periodontal ligament and supracrestal attachment of the tooth, thus avoiding buccal bone remodeling. The socket shield technique performed together with an immediate implant is a recently developed alternative method for the preservation and maintenance of tissues around a dental implant. In this method, a buccal root fragment is left in the socket instead of completely removing the tooth, and the implant is inserted palatal to it. This paper reviews the related articles of socket shield technique, which can help oral clinicians understand the technology more comprehensively.
