Introduction: Dental implant placement is a routine practice in dentistry, with a possible uncommon risk of neurosensory injury. The present study analyzed all dental implant claims involving sensory nerve disturbances between 2005 and 2020 in Israel. The study was conducted to understand implant risk management better and improve the patient's safety.
Materials and methods: All legal claims registered by Medical Consultant International (MCI) involving nerve damage claims between 2005 and 2020 were included in the study. The data included demographic details such as age, sex, event date, claim delivery date, and treatment settings. Information on the nerve damage included the damaged nerve, side of injury, and the number of implants performed in the same surgery.
Results: There were 218 claims regarding nerve damage out of 1154 claims for dental implant therapy. The mean age for nerve damage claims was 54.1 ± 11 years. There were more female than male claims (p = 0.02), with 87% of cases concerning damage to the inferior alveolar nerve (p < 0.0001), out of those molar areas being more frequently involved in nerve damage (64.3%, p < 0.0001). The left side was 1.4 times more frequent than the right side (p = 0.043). The risk for nerve injury was 7.4 times higher when placing multiple implants compared to single dental implant (p < 0.0001).
Conclusions: Clinicians should be aware that placement of multiple implants, left-side implant placement, and patient gender may increase risk for a malpractice claim for neurosensory disturbances.
