“…Implants placed in proximity to the mental nerve region represented the highest risk, perhaps partly as a consequence of poor interpretation of radiographic views of the mental foramen and anterior loop of the IAN. 14 The results reported in this paper highlight the need for an adequate safety zone in such cases. Selection of unnecessarily long implants may have further contributed to injury.…”

“…10,23 The general demographics of this patient cohort were similar to previous reports on implant surgery (Table 1). 7,[9][10][11][12][13][14][15][16] A significant deficiency in consent practice for implants has been previously reported. 24 In this study, symptoms appeared to be aggravated by the lack of informed consent, which was given to only 30% of the patients, most of whom were not specifically warned about potential nerve injury.…”

“…[5][6][7][8][9][10][11][12] Injuries to the inferior alveolar nerve during dental surgery remains a common and complex clinical problem with major medicolegal implications. 1 Sensory nerve injury often results not in numbness which is a common misapprehension but in altered sensation and/or pain.…”

Introduction Nerve injury during implant placement is a preventable, serious complication with major medico-legal implications. The incidence of implant related inferior alveolar nerve (IAN) injuries varies from 0-40%. This article presents four cases of IAN injury following mandibular implant placement with early removal, referred to the oral surgery department, King's College Hospital, London. Objectives To assess sensory disturbance and recovery in patients with implant related IAN injury and assess whether early removal of the implants promotes neural recovery. To present recommendations on how to best deal with suspected/actual nerve injuries and prevent their occurrence. Methods Over the last two years, four patients referred for specialist opinion to the oral surgery department were identifi ed as having sustained implant related IAN injury with early removal (18 hours to four days post-injury). Data were collected by referral to health records. Results All patients suffered from numbness of the affected inferior alveolar dermatome with three out of four cases also experiencing some form of neuropathic pain. Cases 1 and 2, who had their implants removed at 18 and 36 hours post-injury respectively, regained almost complete sensory recovery. Case 1 also had adjunctive NSAID and steroid therapy. Cases 3 and 4 suffered complete numbness in the inferior alveolar dermatome and did not experience any improvement in sensation following removal of their implants at two and four days post-injury respectively. Both patients with signifi cant persistent neuropathy (Cases 3 & 4) reported functional problems. Conclusion This cohort of patients may demonstrate that early removal of implants associated with IAN injury (less than 36 hours post-injury) may assist in minimising or even resolution of IAN neuropathy. Adjunctive corticosteroid and high dose non-steroidal anti-infl ammatory therapy also appears effective. Implant related IAN injury is a preventable, elective procedure and a suggested protocol of management of suspected injuries, for dental practitioners, is presented.

“…The incidence of dental implant related nerve sensory damage (NSD) has been shown to be as high as 40% in past studies [8,11,[13][14][15][16][17][18][19][20] although at least one prospective large cohort study has shown that risk of TG injuries can be eliminated with meticulous attention to planning and observing good surgical protocols. [61] Nevertheless, the large variation in the reported incidence of NSD suggests that this serious complication of dental implant surgery has not yet been adequately evaluated and reported.…”

“…[4][5][6][7] The inferior alveolar nerve (IAN) and mental nerve (MN) and the lingual nerve (LN) are the most commonly damaged nerves during dental implant treatment [6,[8][9][10][11][12] with some studies reporting an incidence rate of up to 40% of nerve damage following implant placement surgery in the mandible related to the depth and the width of the implant bed preparation. [8,11,[13][14][15][16][17][18][19][20] Local anesthetic injections also cause TG damage due to mechanical or chemical injury. [8,20,[24][25][26][27] Hemorrhage within the inferior dental canal (IDC) can cause chemical nerve injury (related to the iron content in the hemoglobin directly irritating the nerve tissue), or damage due to direct mechanical pressure and indirect ischaemia.…”
