In recent years, dental implant is widely used in many cases, but satisfactory results can not always be obtained. This report showed a case of bladevent endosseous implant in the maxilla which had caused false trigeminal neuralgia of the infraorbital nerve, peripheral osteitis of the maxilla and maxillary sinusitis on the left side. Removal operation of the implants, radical antrum operation of the sinus, and medicinal therapy for neuralgia were performed.
