Complications in dental implant surgery are infrequent, causing the technique to become an almost a routine procedure. However, significant bleeding episode may always occur during dental implant placement. An accurate preoperative assessment of the patient followed by good surgical technique is a key factor in the management of hemostasis. The cause of bleeding can be artificial, such as surgical injury of the blood vessle, or general, and that is in most cases systemic disease, medication­induced bleeding or coagulopathies. Although novel oral anticoagulants offer the advantage of having fewer drug interactions than warfarin, no dietary and food restrictions, and no requierements for regular blood tests, they have led clinicians to deal with two clinical issues, such as the hemorragic risk in case of noninterruption or the risk of thromboembolism in case of suspension of the treatment. Doctor of dental medicine should have thorough knowledge of the anatomical features of a surgical site to avoid risks of bleeding, and if the bleeding occurs, a clinician must be able to stop the bleeding using different measures of hemostasis. Nutritive intraosseus canals my contain significant arteries that can be damaged during an osteotomy. These are less dangerous anastomosis of the alveoloantral artery in the lateral wall of the maxillary sinus and, if severed, they are life­threatening sublingual and submental arteries in the anterior mandible. A CBCT analysis can reveal such anatomical structures to be avoided preoperatively. It can help with the treatment plan and the choice of the suitable dental implant diameter and length.
