Abstract
This paper report a case of delayed implantation using staged ridge split combined with guided bone regeneration(GBR)in a patient with a knife-edge alveolar ridge due to free-end edentulism in the posterior mandible.For a patient with insufficient alveolar ridge crest width in the mandible who met the indications for ridge splitting,a two-stage ridge split was performed.The first surgery involved splitting the cortical bone to promote bone remodeling.One month later,a second ridge split was carried out with simultaneous implant placement,combined with GBR to achieve horizontal ridge augmentation.The horizontal alveolar bone width increased by 4～5 mm,meeting clinical requirements for implantation while reducing the risk of buccolingual implant exposure,minimizing surgical trauma,and shortening the treatment period.However,a two-year follow-up revealed buccal bone plate resorption in the surgical area at a rate of 0.1～0.3 mm/year.The staged ridge split technique provides a treatment option for patients with severe horizontal alveolar ridge deficiency(width≤3 mm)in the posterior mandible,but attention should be paid to the issue of long-term bone resorption.关键词
