One of the most common sites of injury of the facial skeleton is mandibular condyle. However, it is the least diagnosed site of trauma in the head and neck regions. A trauma to the mandible and specifically condylar zone during childhood, may lead to asymmetry or mandibular bilateral distortion, which is usually manifested in the second decade of life when the etiology is unknown to most people. This report is about an adult male complaining about facial asymmetry with an unknown source. Obvious clicking at the right side and shorter right ramus and condyle's head deviation directed us to a childhood trauma and fracture...

The prosthodontic treatment of patients with a retrognathic edentulous maxilla should consider the restoration of the lower facial profile and access for oral hygiene. This clinical report describes prosthodontic treatments of a patient with edentulism who presented with repeated fractures of the denture teeth of a maxillary implant-supported complete fixed dental prosthesis (ICFDP) and a mandibular implant-supported overdenture. Considerable plaque accumulation was noted on the ICFDP, which was replaced with an open palatal design implant-supported overdenture...

This step-by-step manuscript describes surgical technique of segmental mandibulectomy in the dog. This surgical procedure may be indicated for the excision of small- to mid-sized neoplasms or as a salvage procedure for mandibular fractures. Long-term postoperative complications are not common and cosmetic appearance following the procedure is generally acceptable to the pet owner.

Temporomandibular joint replacement (TJR) with alloplastic prosthesis has shown promising long-term results in end stage joint disorders. We present a case of young woman with painful ankylosis that where reconstructed with TJR, due to a complex mandibular fracture with dislocation of the left condyle into the middle cranial fossa two years earlier. At the age of 18 the subject underwent a total joint replacement with custom-made alloplastic TMJ prosthesis. To determine the bone response and remodeling activity around the prosthesis, a F18 PET/CT-scan was used...

INTRODUCTION: Faciomaxillary fractures (FMF) occur in a significant proportion of trauma patients. Nearly all polytrauma patients and even those with isolated FMF are managed under general anesthesia for definitive management. We propose the use of regional nerve blocks as a safe and effective means for open reduction and fixation of isolated FMF. AIM AND OBJECTIVES: The aim is to evaluate the feasibility, effectiveness and safety of base of skull maxillomandibular and distal trigeminal nerve blocks in the management of FMF...

Bisphosphonates (BPs) bind selectively to hydroxyapatite and accumulate in sites of active bone remodeling, where they inhibit bone turnover by interfering with osteoclastic recruitment, activity, and survival. For this reason, they are used in oncologic patients to prevent, decrease, and delay potentially life-threatening skeletal-related complications associated with multiple myeloma (MM) and metastasis, including hypercalcemia, pain, and pathologic fractures. Despite substantial benefits, treatment with BPs can be associated with the development of osteonecrosis of the jaw (ONJ), a pathologic condition for which pathophysiologic mechanisms are not completely defined and current criteria for prevention, diagnosis, and management are based largely on expert recommendations and guidelines...

Numb chin syndrome (NCS) is a multifactorial neuropathic disorder associated with paresthesia to the chin, lip, and oral mucosa, particularly arising as a sequela to various dental-related procedures or infections in the mandible. Timely elucidation of the underlying etiology is of paramount importance as the presentation of NCS could serve as a harbinger of malignancy or metastatic disease. This report describes an unusual case of NCS developing synchronously with a vertical root fracture and odontogenic infection in a mandibular first molar...
