The Anatomical Location of the Mandibular Canal: Its Relationship to the Sagittal Ramus Osteotomy
Published in Niall MH McLeod, Peter A Brennan, 50 Landmark Papers every Oral & Maxillofacial Surgeon Should Know, 2020
Inferior alveolar nerve injury occurs in 31–37% of patients following a sagittal split osteotomy and may be associated with medial retraction of the soft tissues medial to the ramus, the buccal cortical cut, the splitting of the bone, or fixation.6–9 Yoshida et al. and Yamamoto et al. found that neurosensory disturbance was associated with the proximity of the nerve to the lateral cortex.10,11 For this reason, understanding of the position of the nerve when making the surgical cuts and splitting the mandible is important. Modifications in instrumentation and technique have been proposed to reduce the incidence of inferior alveolar nerve injury, but to date there is no robust evidence supporting one technique over another.12
Oral cavity
Published in Neeraj Sethi, R. James A. England, Neil de Zoysa, Head, Neck and Thyroid Surgery, 2020
The sensory innervation of the oral cavity is from the trigeminal nerve. The maxillary division (V2) supplies the greater palatine and nasopalatine nerves to the hard palate. It also supplies the superior alveolar nerve to the teeth. The mandibular division (V3) supplies the lingual nerve to the floor of mouth and tongue, inferior alveolar nerve to the teeth and buccal nerve to the buccal mucosa. Special taste sensation is also supplied to the anterior two-thirds of the tongue via the chorda tympani branch of the facial nerve.

Comparative evaluation of short or standard implants with different prosthetic designs in the posterior mandibular region: a three-dimensional finite element analysis study
Published in Computer Methods in Biomechanics and Biomedical Engineering, 2023
The cone beam computed tomography images used in the study were the posterior left mandibular with missing molars. CBCT images were exported in DICOM format and they were used to construct 3D FEA models of the posterior mandible via a software program (Mimics Innovation Suite, Version 21.0). Bone structures were modeled to have a 2-mm-thick compact bone layer enclosing spongy bone. The inferior alveolar nerve was considered while modeling, and the inferior alveolar nerve was placed 2 mm below the implant (García-Braz et al. 2019). To simulate the atrophic mandible, the geometric modifications were performed using a computer program (SolidWorks, Version 2019). The size of regular mandible models was 24 mm in height, 33 mm in mesiodistal length, and 16 mm in buccolingual width. The size of atrophic mandible models was 20 mm in height, 33 mm in mesiodistal length, and 16 mm in buccolingual width. The regular mandible models were restored with standard implants. While the atrophied mandible models were restored with short implants (Figure 1).

VMs are the most common bony vascular lesions. Usually, a VM of the facial bone is an asymptomatic mass causing various grades of dysmorphism [17]. However, when a VM arises in the maxilla or in the mandible, it may cause tooth displacement. It should be noted though that this behavior is more typical of AVMs. The formation of new venous vessels leads to a reorganization of the surrounding bone. This typically produces a centrifugal radiating mass especially in the maxillary and zygomatic bone, which are low resistance bones [19]. In other cases, when the VM occurs in the medullary compartment of the bone, it may replace the healthy tissue and cause some minor swelling. It can also produce other symptoms, such as inferior alveolar nerve pain, or numbness, which are both caused by compression.

Pre-prosthetic procedures included: attendance of a program of professional dental hygiene to nullify differences in preoperative hygiene conditions and atraumatic extractions of remaining 3 maxillary teeth without elevation of the full-thickness flap to preserve the bone ridges and soft tissue. The alveolar nerve block was obtained by using 2% mepivacaine. Both groups of participants, with and without diabetes, were indicated for immediate complete denture in order to provide T2DM participants with adequate mastication and to standardize the study conditions. The existing mandibular complete dentures were replaced on the day of receiving maxillary immediate complete dentures. The surgical protocol and clinical evaluation were conducted at the Clinic of Oral Surgery, School of Dental Medicine in Belgrade. The fabrication of new dentures (maxillary immediate complete dentures and mandibular complete dentures) and post-insertion denture adjustments necessary for removing difficulties that included pain and discomfort were performed at the Department of Prosthodontics, School of Dental Medicine in Belgrade. The study received approval from the Ethics Committee of the School of Dental Medicine, University of Belgrade (No. 32/36 in 2012 year) and was conducted in accordance with the Helsinki Declaration.
