non-membrane technique of GTR in distal circumferential defect around upper molar ( 牙周再生術 )

before treatment: there was a deep probing depth (over 10mm) around distal area of upper right terminal tooth (1st molar) and an obvious edentulous ridge collapse.
no s/s and no obvious mobility, good candidate for trial of GTR procedures
thorough debridement of all granulation tissue around the defect after flap elevation, large distal circumferential defect was found
24% EDTA (PreGel) for root conditioning
after thorough wash-out of EDTA with abundant distilled water, Emdogain was applied all along the root surface and all the bony defect
filling the bony defect with cancellous FDBA
tension-less primary closure of the flap with 5-0 nylon silk
8-day post-op, suture removal
20-day post-op
8-month post-op




20-month post-op
