pre OP pano :

Left sinus lifting case

-- pre-op CBCT
-- thin buccal side bone plate
-- pizeotome lateral window approach
-- Bio-oss 0.5cc + FDBA 0.25 + teruplug
-- Collagen mem
-- suture 5-0 nylon

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
   C. new collagen membrane (Taiwan company pig dermis ), hard to control
   D. suture technique and material
   E.  mini implant ??



2013/09/16
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

Thanks god ....

Lateral window or crestal approach sinus lifting??

Left sinus lifting (lateral window approach method), b-TCP + HA + FDBA, collagen mem.

第六次lateral window sinus lifting Sx.

為什麼是第六次？？　因為只有這次有比較完整記錄．．．　

但是助手拍的ＰＨＯＴＯ還是差強人意...
