risks during surgery
Dental implants are a surgical procedure and carry the normal risks of surgery including infection, excessive bleeding, and bone necrosis or tissue damage around the implant. Nearby vessels or nerves, such as the inferior alveolar nerve, sinus and blood vessels, can also be injured when drilling into bone or placing an implant. Even when the lining of the maxillary sinuses is perforated by an implant, long-term sinusitis is rare. The inability to place the implant into the bone to provide stability for the implant (referred to as primary stability of the implant) increases the risk of failure to fuse with the bone.
Immediate risks after surgery
Infection (preoperative antibiotics reduce the risk of implant failure by 33% but do not affect the risk of infection).
excessive bleeding
Reflex soft tissue collapse (less than 5%)
Risks of the first six months
Initial implant stability
Initial implant stability refers to the stability of a dental implant immediately after implantation. The stability of a titanium screw implant (implant) in the bone after a patient’s surgery can be evaluated using a resonance frequency test. Sufficient initial stability may allow immediate loading with construction of the prosthesis, although early loading poses a higher risk of implant failure than late loading.[40]
