Evaluation of in vitro resistance of different 2.0-mm titanium plates on the mandibular angle sectioning.

Objective: The purpose of this study was to compare, by mechanical in vitro testing, a regular 5-hole plate and a long 4-hole plate with a regular 4-hole plate, applied to stabilize a simulated mandibular angle fracture.

Study Design: The plates from the 2.0-mm titanium-based system were adapted and stabilized passively in the same site in both groups using four screws, 6 mm long.

Retained third molars removal in a severely resorbed edentulous mandible. A case report.

The presence of asymptomatic third molars can represent a potential problem in the mandible when these teeth are retained and the patient has lost all normally erupted teeth. Once the mandibular first and second molars are removed, the mandibular body becomes weaker with time, increasing the complexity, morbidity and incidence of complication in the surgical procedure to remove the retained third molar. This paper reports a case where the mandibular third molars retained in a severely resorbed mandible were removed in a 54-year-old female patient.

Retropharyngeal and cervicofacial subcutaneous emphysema after maxillofacial trauma.

Introduction: Subcutaneous emphysema in the cervical region is a well-documented event that may occur secondary to tonsillectomy, dental treatment, oropharyngeal barotraumas, scaling and root planning therapy, punch biopsy, endotracheal intubation, orthognathic surgery, extraction of impacted teeth, or after maxillofacial trauma. After trauma episodes, subcutaneous emphysema may be caused by a maxillary antral wall fracture that occurs when air pressure is introduced into the fascial planes of the connective tissue. Retropharyngeal emphysema is a severe condition associated with traumatic aerodigestive tract injury and may be associated with life-threatening situations requiring prompt attention and diagnosis in order to prevent serious consequences.
