Prevention and management of life-threatening complications during dental implant surgery: a clinical case series.

Complications can occur during implant placement; thus, clinicians should be aware of all potential outcomes, and staff members should be fully prepared to respond in case of emergency. A thorough medical history, precise surgical technique, knowledge, and skill are essential to prevent complications. The most serious complications, which could threaten the patient's life, are airway obstruction, bleeding, aspiration of the implant or its parts, infection, cavernous sinus thrombosis, nerve injury, and mandibular fracture.
