Patient information

Male 45 yrs old Non-contributory NKDA Drink occasionally, smoke 1 pack a day

PDH

Scaling and subgingival curettage PFM bridge on #23,24-26 Implant placement on #32, 36, 37, 42 Extraction on #13,14,15,16

Diagnosis & Treatment Plan

Generalized severe chronic periodontitis Treatment plan Scaling and subgingival curettage Sinus augmentation using xenograft Implant placement on #13,14,15,16

Panorama taken at the initial visit severe vertical bone resorption has been appreciated on the right posterior maxilla

Sinus window preparation with the help of piezoelectric devices

Sinus augmentation has been performed with the use of xenograft(porcine origin)and resorbable membrane.

Single interrupted suture has been done to adapt the buccal and lingual flaps.

Panorama taken six months after sinus augmentation before implant placement. The augmented bone can be easily appreciated.

Occlusal view of the surgical site taken just before implant surgery.

The implant placement has been done on #13,14,15,16 using Neobiotech IS-II active fixtures. Fixture direction pins have been placed to check occlusal relationship.

The thin buccal bone on #13,14 area can be easily appreciated.

Allograft has been placed on the thin buccal bone area together with resorbable membrane.

Single interrupted suture has been done to adapt the buccal and palatal flaps with one horizontal mattress suture holding the resorbable membrane underneath the flaps.
