The regular 5-hole plates and longer 4-hole plates were superior to the regular 4-hole plates. Furthermore, no statistically significant difference was found between the regular 5-hole plates and long 4-hole plate.Conclusions The length and shape of plates did not interfere with the effectiveness to stabilize the fragments.

Resistência de quatro técnicas de fixação utilizadas no tratamento das fraturas subcondilares. Estudo in vitro em mandíbulas de poliuretano / Lucas Cavalieri Pereira. --Piracicaba, SP : [s.n.], 2011.

Atrophic jaw fractures are common in the elderly population. Edentulous jaws have greater structural fragility due to bone resorption caused after tooth loss. The major cause of these fractures is falling from one's own height, since these patients have a greater cognitive deficit, physiologically inherent to senity. The treatment of these fractures becomes a challenge for the Oral and Maxillofacial surgeon, because the absence of teeth and the lack of anatomical landmarks, disfavor the reduction of the fracture. Other aggravating comorbidities may interfere with bone repair or choice of treatment. Therefore, the surgeon must take into account the age, systemic condition and the degree of mandibular atrophy for the correct conduction. This work aims to to carry out a systematic review in which the treatment methods and epidemiological data on the subject were surveyed, including case reports and case series, which contemplate the degree of mandibular atrophy, specify the treatment method and follow-up minimum of 3 months. Through these data, a qualitative analysis of the studies was carried out, highlighting the forms of treatment for this condition.
