open collagen membrane technique in socket preservation and further implant therapy with osteotme sinus lift

Patient is a dentist (prosthodontist), suffering from gum boil on buccal side of upper right 2nd premolar about 3 years ago but EPT test was (+) on this tooth. In that time, p't had no time to treat this s/s.
1 year latter, this s/s got worse and p't came back from Germany for help.
GP tracing showed the focus of lesion was coming from 1st molar. Root fracture should be R/O and socket preservation was indicated in the mean time of extraction.
Remove the crown 1-week before carrying out the socket preservation
1-week later, carry out the socket preservation procedures with open collagen membrane technique

Cover back the membrane and suture back the flap with the requirement of open collagen membrane technique

15-day post-op. Then p't went back to Germany for his further study.
