Dentoalveolar surgeryDoes an Association Exist Between the Presence of Lower Third Molar and Mandibular Angle Fractures?: A Meta-Analysis
Section snippets
Study Design
To address the research objectives, we designed and implemented a systematic review and meta-analysis according to the Cochrane Collaboration guidelines10 for systematic reviews and the PRISMA statement11 (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The review protocol was registered at the PROSPERO database (registration no. CRD42016047057). The systematic review was structured according to the recommendations by Dodson.12
The present review included all reports of the
Results
The search strategies resulted in 411 studies. After the initial screening, 204 duplicate results were eliminated, and 207 studies remained for the reading of the titles and abstracts. From these, 116 articles were outside the objective of the study, 36 were literature reviews, 28 were case reports, and 2 were letters to the editor. The full text of the 25 remaining studies were analyzed, with 3 excluded because they had not enumerated or included patients without lower third molars and/or
Discussion
The main objective of the present study was to verify, through the comparison meta-analysis, the association between the presence of lower third molars and the risk of mandibular angle fractures in adults. The hypothesis was that the presence of the lower third molar would predispose to a greater risk of mandibular angle fracture. The secondary outcome evaluated in our study was the relationship of mandibular fractures with the position of the third molar, studied using a proportion

Correlation of radiomorphometric indices of the mandible and mandibular angle fractures
2022, HeliyonCitation Excerpt :Management of MAFs is difficult due to complex mechanics of the mandibular angle such as thin cross-section, abrupt change in the path of curvature, presence of third molars, and attachment of the muscles of mastication applying loads along different vectors [19]. A number of studies have reported a positive association between third molar impaction and MAF [12,20,21]. However, studies on the correlation of morphometric indices of the mandible and MAF are limited.
Titanium versus magnesium plates for unilateral mandibular angle fracture fixation: biomechanical evaluation using 3-dimensional finite element analysis
2022, Journal of Materials Research and TechnologyCitation Excerpt :In order to avoid non-union and mal-union in the outcome, this fracture must be fixed for proper union of the segments. The treatment of mandibular angle fractures is highly challenging due to its unique pathophysiology and associated complications [7,8]. There are various factors to be considered while treating mandibular angle fractures, like the anatomy and physiology of the angle because of the attachment of various masticatory muscles, the location of the erupted or impacted third molar teeth, the amount of masticatory load acting on the angle and the thickness of the surrounding outer cortical bone covering the inner medullary complex [9–13].
Surgical Management of Mandibular Angle Fractures: Does the Extraction of the Third Molar Lead to a Change in the Fixation Pattern? A European Multicenter Survey
2021, Journal of Oral and Maxillofacial SurgeryCitation Excerpt :The mandibular angle is one of the most frequent sites of mandibular fractures because of the complex biomechanics of this region, its thin cross-sectional area, and the presence of the third molar.1-7 Two recent meta-analyses showed that the presence of an impacted third molar (3M) increased the risk of mandibular angle fractures (MAFs) in adults by 2-fold8 to 3.16-fold.9 However, despite consensus on the indications for the removal of a 3M in the fracture line,6,10-15 the optimal surgical management of MAF remains a matter of debate.7,16-21

Buccal, lingual, mesial, and distal surfaces of teeth were fabricated at 6° of an angle; the margins and point angles were rounded.
