PURPOSE Osseointegrated implants lack a periodontal ligament. Nevertheless, masticatory function in subjects with implant-supported restorations appears similar to function in those with natural dentition. It is not clear how the neurophysiologic mechanisms that modulate jaw movement are associated with osseointegrated implants. This study examined the output from the inferior alveolar nerve du...

When the lower alveolar nerve is affected by any mechanical, iatrogenic, neoplastic or inflammatory process, we can clinically see the appearance of typical trigeminal symptoms, together with typical radiological changes of the mandibular canal, consisting in widespread hypodensity, increase in diameter and disappearINDIRECT POST-IMPLANT LESIONS OF THE INFERIOR ALVEOLAR NERVE. RADIOLOGICAL AND ...

Fifty-four injection injuries in 52 patients were caused by mandibular block analgesia affecting the lingual nerve (n=42) and/or the inferior alveolar nerve (n=12). All patients were examined with a standardized test of neurosensory functions. The perception of the following stimuli was assessed: feather light touch, pinprick, sharp/dull discrimination, warm, cold, point location, brush stroke ...

Premature loss of posterior teeth in the mandible, failure to replace lost teeth as well as systemic factors may result in progressive resorption of the alveolar ridge. At present, oral and maxillofacial surgeons aim to reconstruct the lost bone and masticatory function via posterior mandibular grafting and/or implants. However, anatomic limitations such as the inferior alveolar nerve (IAN) may...

The extraction of impacted mandibular third molars has long been associated with the dreaded and rarely, grave and irreversible complications. The oral and maxillofacial surgeons’ dogma strongly links most complications with the proximity of inferior alveolar canal and the impacted teeth, the relationship of which is still a topic of debate among surgeons. In this randomized, prospective case s...

AIM   To describe a case of endodontic sealer (AH Plus) penetration within the mandibular canal after root canal treatment with resolution of pain and paraesthesia after a non-surgical approach, including treatment with prednisone and pregabalin. SUMMARY   A 37-year-old woman underwent root canal treatment of the left mandibular second molar tooth. Postoperative periapical radiographs reveale...

BACKGROUND AND AIMS Inferior alveolar nerve block injection is one of the common intra oral anesthetic techniques, with a failure rate of 15-20%. The aim of this study was to evaluate the position of the lingula as an index for this injection. MATERIALS AND METHODS Thirty eight panoramic radiographs of 7-11 year old patients were analyzed and the distance between the lingula index and occlusa...

OBJECTIVES This article, the second in a two-part series, continues the discussion of inferior alveolar nerve lateralization/transposition for dental implant placement. The aim of this article is to review the scientific literature and clinical reports in order to analyse the neurosensory complications, risks and disadvantages of lateralization/transposition of the inferior alveolar nerve follo...

PURPOSE Damage to the inferior alveolar nerve when extracting lower third molars is often caused by the intimate relationship between the nerve and the roots of the teeth. The technique of coronectomy, or intentional root retention, may minimize this problem. PATIENTS AND METHODS Forty-one patients underwent coronectomy on 50 lower third molars with follow-up of at least 6 months. The techniq...
