What is a common complication associated with an implant on #7?

The most common complication associated with an implant on tooth position #7, which is typically the maxillary left central incisor, is the penetration of the nasal cavity. This is due to the anatomical proximity of the roots of the maxillary anterior teeth to the nasal cavity and sinus. When placing an implant in this area, there is a risk that improper placement, particularly if the implant is positioned too mesially or inferiorly, could lead to a perforation of the maxillary sinus or the nasal cavity, resulting in complications such as sinusitis or communication with the nasal cavity.

The locations of the sinus and nasal cavity make careful planning and imaging essential prior to implant placement. This anatomical consideration is crucial for successful outcomes in implant dentistry, especially for anterior maxillary implants, where proper angulation and spacing must account for these structures.
