Objectives: to analyze the possible etiological factors associated with mandibular fractures occurring during tooth extractions. Methods the following data were collected: sex, age, the extracted tooth, tooth classification, angulation, level of bone impaction, pathological association, recognized technical errors, instruments used at the time of the fracture, and the surgeon’s experience and specialization, if applicable. An electronic search of the following databases was performed: PubMed/Medline, Lilacs, Embase, and Scopus. The data were tabulated and analyzed using the Chi-square test, a P-value less than 0.05 was considered significant. Results: a total of 80 cases were selected. Sex and age were not statistically significant (P>0.05). The teeth most associated with fractures were the mandibular third molars; however, the location was not significant.

Background Angle fractures are quite common considering that the angle of the mandible forms an area of lower resistance which contains a thicker upper border, a thin basilar bone, and the presence of an impacted mandibular third molar. Common complications of mandibular third molar surgery include alveolar osteitis (dry socket), secondary infection, nerve dysfunction, and hemorrhage. Reports of mandibular fracture during and after third molar removal are uncommon. Purpose The purpose of this paper is to discuss the risk and predisposing factors that should be analyzed regarding the possibility of immediate and late mandibular angle fractures and their need for surgical treatment as a means through which to remove impacted molars. This study is based on a thorough review of the literature as well as on one immediate and one late mandibular angle fracture as described by the authors' own personal experience.
Mandibular Angle Fracture after Third Molar Extraction: A Case Report and Review of the Literature
2020
The extraction of third molar teeth is one of the most common procedures in the specialty of oral and maxillofacial surgery. On some occasions, the extraction results in complications, including less serious ones, such as infection, alveolar osteitis, bleeding and hemorrhage, and paresthesia. In some cases, fracture of the mandible can be observed and is classified as a severe form of these complications. The following case present a fracture of the angle of the mandible as a complication of the extraction of the lower wisdom tooth.
Surgical treatment of mandibular fracture resulting from first molar extraction: case report
Research, Society and Development, 2021
Extraction is one of the most common procedures performed by dental surgeons in their daily clinical practice. Among the trans and postoperative complications associated with this procedure can be mentioned the occurrence of trismus, infections, edema, alveolitis, paresthesia or fractures. The purpose of this study was to report a clinical case of a mandibular fracture associated with first molar extraction, approaching its main risk factors and treatment. Patient JSS, 24 years old, female, was referred to the service of Maxillofacial Surgery due to complications resulted from the extraction of element 36. On physical examination, was observed the presence of fragment mobility, communication of bone tissue with the oral environment and pain complaint was reported by the patient. Computed tomography showed the presence of a fracture in the region of the mandibular body on the left side. The planned surgical proposal was the intraoral debridement of bone fragments, extraoral access in...
Mandibular fracture during mandibular third molar extraction
The Internet Journal of …, 2009
Pre-operative planning for the extraction of mandibular third molars is of fundamental importance, particularly in patients over the age of 40 years, in whom osteotomies and odontotomies procedures must be included to prevent mandibular fractures Conservative treatment of the mandibular fracture has advantages and disadvantages, and can present excellent results when well indicated and performed. The main aim of this article is to relate a case of fracture of the mandibular angle in a 40-year old patient, as a result of third molar extraction on the right side. The patient had two fracture lines favourable to reduction, reported feeling a difference in dental occlusion and was treated with intermaxillary fixation with an Erich bar for 45 days. The follow-up shows complete bone consolidation of the fracture traces after four years.
Late mandibular fracture after attempted third molar surgery: case report
ARCHIVES OF HEALTH INVESTIGATION, 2020
Removal of lower third molar corresponds to one of the most common procedures in oral surgery. The extraction can result in several intraoperative or postoperative complications, especially when fully impacted molars are involved. This case report describes a mandibular angle fracture following removal of a fully impacted lower third molar of a 41 years old male patient. The fracture occurred 3 days after the attempt to extract the tooth 38 by a dentist surgeon. Several factors influencing the possibility of fracture including gender, age, dental position, and angulation were reviewed and associated with the injury. A fracture line in the angular region of the jaw was observed in radiological and tomographic analysis, both essential to perform the diagnosis. Open reduction internal fixation treatment approach was realized to ensure the best patient’s recovery. We conclude that the difficult to maintain a soft diet and the complete dentition factor could have been determinant to caus...

Background: There are controversies and debates over the risks associated with the retention of asymptomatic impacted mandibular third molars when compared with the need for their extraction. Objective: To determine the incidence and types of complications after the surgical extraction of asymptomatic impacted mandibular third molars. Patients and methods: This was a four-year prospective, single blinded, clinical study, carried out at the Dental and Maxillofacial Surgery Clinic of our institution. The variables analyzed were patients' age, gender, types and site of impaction, and complaints during reviews. Results: Overall, 115 patients with asymptomatic impacted mandibular third molars were seen, and 63/115 (54.8%) were treated. The age of the patients ranged from 26-65 years with a mean age of 42.3 ± 3.4 years. Majority (n=47, 74.6%) of the patients were in the age category of 31-50 years. The male: female ratio was 1: 1.3. Mesioangular (n=33, 52.4%) impaction was the most common. Complication rate was 4.8%, comprising two (3.2%) females and one (1.6%) male who had numbness of the ipsilateral lower lip. The numbness resolved by the 4th post-operative week, and the extraction sockets clinically healed uneventfully. Conclusion: This study shows that the complications associated with the surgical extractions of the asymptomatic impacted mandibular third molars were acute, neurological and without a permanent sequel.
Mandibular fracture after third molar removal
Journal of Oral and Maxillofacial Surgery, 2000
Purpose: Mandibular fracture after impacted lower third molar removal is a rare, but major, complication. The factors leading to a mandibular fracture secondary to third molar removal are analyzed retrospectively. Patients and Methods: Six patients who suffered from a mandibular fracture as a complication after third molar removal were examined clinically and radiographically. Results: All fractures occurred an average of 14 days postoperatively. The patients were 42 to 50 years old and were all fully dentulous. All grades of tooth impaction were included. Conclusions: The major risk factor for this complication seems to be advanced age in combination with a full dentition. The degree of tooth impaction is less important. Preexisting bone lesions weaken the mandible and further predispose to a fracture.
Late treatment of mandible fracture after third molar removal
Research, Society and Development, 2022
Surgical management of impacted third molars is a treatment performed by dentists and its indicated for various conditions, among the indications has the prevention of mandibular fracture, but this is a factor that has been discussed and is controversial. Fractures caused by a third molar can occur, and on the other hand, the fractures after or during the management of impacted third molar are a possible complication. Surgical planning as the indication to the surgery has to be performed to avoid complications as the fracture. Thus this study aims to report a case about a mandible fracture after third molar extraction, presenting edema, pain, and restriction in mandible mobility in 01-day follow-up. A 27-year-old female was referred to the oral and maxillofacial surgery service of the Santa Casa Hospital of Araçatuba (Araçatuba, Brazil), reporting dental history of third molar removal, with immediately chief complaints. In the assessment, the patient presented edema, pain, malocclus...
Unerupted lower third molars and their influence on fractures of the mandibular angle and condyle
British Journal of Oral and Maxillofacial Surgery, 2012
Our aim was to assess the influence of the presence and state of impaction of mandibular third molars on the incidence of fractures of the mandibular angle and condyle. We designed a retrospective study of patients who presented for the treatment of mandibular fractures from January 2006 to April 2011. The independent variables were the presence and degree of impaction of lower third molars, and the outcome variables were the incidence of fractures of the mandibular angle and condyle. The information was acquired from hospital records and panoramic radiographs. Personal data included age, sex, mechanism of injuries, and number of fractures of the mandibular angle and condyle. We studied 110 fractures of the mandibular condyle and 80 of the angle. The incidence of fractures of the mandibular angle was higher in the group with incompletely erupted third molars (37/80, p < 0.001) and that of condylar fractures was higher in the group without (67/110, p < 0.001). An incompletely erupted third molar reduces the risk of condylar fractures and increases the risk of fractures of the mandibular angle.
