Final answer:
Complications for a maxillary sinus lift, which may relate to a 'max ant implant', can include sinus membrane perforation, infection, sinusitis, issues with bone graft integration, and implant failure.
Step-by-step explanation:
Possible complications for a maxillary sinus lift, which may be abbreviated as 'max ant implant' (assuming it refers to a 'maxillary anterior implant'), could include sinus membrane perforation, infection, bleeding, or sinusitis. In some cases, there might also be issues with bone graft integration or implant failure if the bone does not heal properly around the implant. It is essential for patients to follow post-operative care instructions and keep follow-up appointments with their dental specialist to monitor healing and address any complications early.
