2.  The infraorbital foramen is located 6 to 9 mm below the infraorbital rim in the medial third of the orbit.

3.  Sinus septa have a higher incidence in the first and second molar region.

4.  Removal of a Dental Implant Displaced Into the Maxillary Sinus After Final Restoration

5.  The mental foramen in adults is located at the midpoint of the inferior border and the alveolar crest in the region of the
second premolar, with variation of 6-10 mm in the anterior-posterior position.

6.  When placing implants in the anterior mandible, the mental foramina and their anterior loops and the mandibular incisive
canals must be considered.

7.  Concavities on the medial surface of the mandible such as the submandibular and sublingual fossae together with the lingual
foramina should also be considered in order to avoid vascular damage.

8.  The maxillary artery is responsible for the blood supply of the mandible and maxilla.

9.  Within the lateral bony wall of the maxillary sinus, there are intraosseous and extraosseous anastomoses between the
posterior superior alveolar artery and the infraorbital artery.

10.  Infections can spread along the veins into the brain, particularly from the canine fossa and the pterygoid plexus.

11.  The trigeminal nerve is the largest cranial nerve and has three main branches: the ophthalmic nerve, the maxillary nerve, and
the mandibular nerve.

12.  The infraorbital and inferior alveolar nerves are prone to sensory disturbances if anatomical boundaries are not respected.

13.  The understanding of the facial anatomy with its associated osseous and neurovascular structures is essential to the implant
surgeon. During treatment planning and implant surgery, certain critical landmarks and boundaries must be respected. The
anatomy of the maxilla and mandible is complex, and the implant surgeon should also keep in mind that many variations exist
between individuals.

14. Thank you very much for your kind attention.
