upper anterior ridge GBR with Ti-mesh

lower anterior tooth area GBR

lower 11 21 severe perio destruction, post-EXT 2 months
-- decorticatino of lower bone
-- Ti-mesh, collagen mem, FDBA 0.5 cc
-- 5-0 nylon suture

-- try to think  question
   A. pre-OP CT to confirm bone shape and quality
   B. tending screw or other space making tool

implant surgery visit (posterior GBR 6 months)
-- remove Ti-mesh  and and periosteum-like tissue attache Ti-mesh
-- about 3-4 mm horizontal bone regain after GBR (original 1-2mm bone horizontal bone width )
-- few residual bone graft particle above ridge
-- mini implant is selected to implant (MDL 2.5 mm x 13mm length )
-- suggest single crown and resin to correct anterior contour

lower posterior ridge GBR and implant

Case :
-- 36 37 EXT s/p b-TCP + HA + colla-tape for socekt preservation
-- flap Sx. after 2 months, still bone graft and poor bone formation
-- remove bone graft, note the buccal wall is intact
-- re-GBR Sx. (FDBA + collagen membrane ) 2012.8.24
-- F/U 6 months, then implant Sx.
-- implant Sx. () 2013.3.1
