NEO-NAVIGUIDE usage in compromised bone width of All-on-4 case with NEOBIOTECH implant

This case presents full mouth teeth replacement with All-on-4 concept treatment.

Patient information

Healthy Australian female patient, 59 years old, came to BFCdental (Bangkok, Thailand) for making new full mouth teeth replacement. She choose all remaining teeth extraction and All-on-4 concept treatment for her treatment option because of her affordable budget, and she need to complete full mouth treatment within 1 trip, 14 days.


This case presents full mouth teeth replacement with All-on-4 concept treatment. We use 4 dental implants and 5 dental implants to support lower & upper fixed hybrid denture. 4 tilted distal implants in all of quadrants had been placed for avoiding anatomical structures. We had used 3D-surgical guide with NEO-NAVIGUIDE kit drilling in upper jaw which is compromised bone width in most of area. After upper implants placement, we use buccal graft with sticky bone & CGF (concentrated growth factor) for guided bone regeneration.
