Patient presented with failing dentition due to caries and periodontally involved teeth. Treatment Plan: To restore esthetics and masticatory function by sequentially restoring mandibular dentition with implant supported lower fixed bridge from 44 to 32 and partial denture for posterior teeth. Full clearance of upper teeth for placement of 4 neo biotech fixtures for full arch bridge. Maxilla implant placement in 15/16, 25,26 region. tooth #17 kept to maintain Vertical dimension for jaw records bone reduction performed to provide space for prosthetic fabrication. jaw records with bite block coping is embeded inside bite block to ensure accurate transfer of bite records try in with 3d printed design of teeth. 15, 16 fitted with angled multi unit abutments to allow passive seat of bridge Occlusion well maintained Good soft tissue adaption of bridge to soft tissues due to try in records

Diagnosis: Periodontally involved teeth 13 to 23 Midline deviated by 3mm to the left Receding gumline exposes unsightly roots. Treatment plan: Remove mobile teeth, debride and placement of 4 Neobiotech IS II active fixtures to support 6 unit implant supported bridge. Bone graft to provide sufficient bone volume around implant to support fixtures. Screw retained design to facilitate regular maintenance. Straight Lips in repose Full Smile Pre- OP radiograph Post Op Radio graft - note healing abutment obstructed by interdental bone due to sub crestal placement of implants Bridge inserted and opg taken to check fit of the implant connections. Emergence profile improved to facilitate seat of the abutment interface to the implant. Treatment outcome:
