ill-fitted prostheses on the lower R't 2nd premolar to 3rd molar(wisdom tooth) area
taking out of the ill-fitted prostheses, large caries on 3rd molar, obvious ridge resorption and lack of buccal keratinized mucosa were found.
before implantation, GBR was indicated.
de-corticolization before building up the bone graft
packing the bone graft(DFDBA+cortical FDBA, LifeNet) after horizontal releasing incision in the inner site of the flap and setting the collagen membrane(E-Z cure)
covering the collagen membrane on the graft
tension-free primary closure of the flap
14-day post-op, suture removal
12-month post-op, time to carry out the implantation
APF to increase buccal keratinized mucosa
FGG from maxillary tuberosity
FGG on the inter-implant area for primary closure
10-day post-op, suture removal
3-month post-implantation, time to carry out the prosthetic treatment
setting the permanent abutments, and shaping the emergency profile of the final prostheses during trial-set to squeeze the inter-implant papilla.
