AI Article Synopsis
- Adequate bone height and width are crucial for successful dental implants, and IAN lateralization is a complex surgery used to create space for implants in atrophied posterior mandibles.
- The study involved ten patients with limited distance between the alveolar crest and inferior alveolar nerve, assessing neurosensory disturbances (NDs) post-surgery using Semmes-Weinstein Monofilaments.
- All patients experienced NDs immediately after surgery, with recovery times ranging from 2 to 4 months, highlighting that IAN lateralization can effectively facilitate dental implants in challenging cases with manageable side effects.
Article Abstract
Background: Adequate bone height and width is the most important parameter for success of implants. Prolonged edentulous area in mandibular posterior region is often associated with atrophy precluding the use of dental implants. Inferior alveolar nerve (IAN) lateralization is a challenging surgical procedure as it involves the exposure of the neurovascular bundle from its compact bony compartment and adequate retraction while immediate placement of implant.
Aim: Evaluation of neurosensory disturbances related to IAN lateralization for implant placement in the posterior atrophic edentulous mandible.
Materials And Methods: Ten patients above the age of 18 years with an edentulous span in mandibular posterior region showing distance from alveolar crest to IAN ≤ 8 mm (CBCT) were included in the study. The postoperative analysis of NDs was done using Semmes-Weinstein Monofilaments (SWM). Readings were made on the 1st and 7th postoperative day and every month thereafter until the neural sensations were restored.
Results: All patients reported neurosensory disturbance on post-op day 1. None of the patients responded to SWM lesser than 4.56 on first postoperative day, which indicated 100% incidence of neurosensory disturbances. The minimum time required for complete recovery was 2.0 months, and maximum was 4.0 months.
Conclusion: IAN lateralization is a useful method for managing the atrophic posterior mandible with dental implants. If done precisely with experienced personnel, it can provide a worthy option for surgical restoration of atrophic mandible with minimal temporary NDs.

Background: Primary non-Hodgkin's lymphoma arising from the skull base is a rare entity most commonly subclassified as diffuse large B-cell lymphoma (DLBCL). This lesion often arises from the clivus and demonstrates a cranial nerve (CN) VI palsy. In this case report and literature review, we document the clinical presentation and management of a case of clival DLBCL, along with a review of current literature pertaining to DLBCL of the skull base.

A 7-year-old French Bulldog presented with an acanthomatous ameloblastoma affecting approximately 30% of the right mandibular body. We utilized a patient-specific 3D-printed surgical template to perform lateral fenestration of the mandible and elevation of the inferior alveolar nerve (IAN), facilitating nerve preservation during subsequent segmental mandibulectomy. The resulting critical-sized bone defect was anatomically stabilized using a patient-specific polyetheretherketone (PEEK) bridging plate.

In daily life, we coordinate both simultaneous and sequential bimanual movements to manipulate objects. Our ability to rapidly account for different object dynamics suggests there are neural mechanisms to quickly deal with them. Here we investigate how actions of one arm can serve as a contextual cue for the other arm and facilitate adaptation.
