Mandibles

Question 1

Which is the tension surface of the mandible?

Where is optimal plate location for interdental space/horizontal ramus fractures?

Answer 1

Tension surface is medially on the oral surface, clearly not ale to put implants here

Options for plates include, ventrolateral, ventral or lateral.

Ventrolateral application likely preferable

Question 2

Which is the compression surface of the mandible

Answer 2

Ventral

Question 3

According to Durket et al (2019 VS) which plate type and position afforded the greatest resistance to bending with simulated bilateral interdental space mandibular fracture

Answer 3

Ventrolateral position of an LCP

Used 6 hole 4.5 LCP w 2 cortex and 4 LHS

Question 4

Differential diagnoses for mandibular neoplasms

Answer 4

Mandibular neoplasms are usually primary and arise either from mesenchymal tissue of the jaw or odontogenic tissue.

Mesenchymal masses include fibrous dysplasia (generally considered to be a developmental lesion), ossifying fibroma, osteoma and less commonly osteosarcoma.

Odontogenic neoplasms are the most common type in the equine skull, but are infrequent; single cases reported incl ameloblastoma, ameloblastic (or ‘intraosseous’) carcinoma, cementoma, ameloblastic fibro-odontoma and complex odontoma

Usually benign but locally aggressive
