Wire Reinforced Acrylic Splint for Jaw Fracture Repair in a Dog with Edentulous Caudal Mandible.
by Brett on Feb.07, 2010, under Veterinary Dental Cases
This is the dog with left mandibular fracture previously repaired with titanium mesh. Three days after the repair the other jaw suffered a pathologic fracture. It was also severely compromised from chronic periodontal disease. Repair was accomplished with a combination of wire, orthodontic chain, composite buttons and acrylic. Wire was passed under the body of the mandible and through the mucosa then tied and wires bent. Two wires on either side of the fractures on both the right and left mandible. Composite buttons were made using a silicone mold on the mandibular canines. Orthodontic massel chain was then attached to all wires and around the canine buttons to form a horseshoe orientation. Acrylic was added in increments while fracture ends were approximated. This relatively non-invasive approach avoids complications with plates commonly associated with pathologic mandibular fractures where bone density is severely compromised. Four days postop the patient is eating well and pain is well controlled.

Jaw Fracture Repair in a Dog Utilizing Titanium Mesh
by Brett on Jan.30, 2010, under Veterinary Dental Cases
This dog had a right mandibular fracture secondary to chronic periodontal disease. The jaw fractured spontaneously. It was repaired utilizing a titanium mesh material and an osteoconductive bone putty. http://www.securos.com/downloads/SI%20VelosityPuttyBrochure5.pdf
The fracture line can be seen overshadowed by the first molar mesial root. The site of the mesial root of the 4th premolar was near fracture. The veterinarian did a great job avoiding fracture when extracting these teeth.
Post extraction the fracture line becomes visible. This was a chronic fracture that had the body had attempted to heal. Fibrous tissue was present around the site and provided minor stability.
View of the right mandible after fitting the titanium mesh. The ventral mandible had considerable fibrous tissue present. Disrupting this would have created more instability. The plate was placed over the fibrous tissue. This gives the appearance on the final radiography that the plate doesn't conform well to the mandible. On the contrary this material is very compliant and fits tightly to the bone with minimal anchorage.

You can appreciate the delicate structure in relation to my fingers. The plate placed was about 5 times the size of this peice that was clipped off of the portion utilized in this case.

Rim mandibulectomy for an acanthomatous ameloblastoma in the mandible of a dog
by Brett on Jan.14, 2010, under Veterinary Dental Cases
Jessie had an oral mass adjacent to the right mandibular canine tooth. The referring veterinarian biopsied it revealing acanthomatous ameloblastoma. A rim mandibulectomy was performed to remove the mass with minimal margins of 1.5 cm.
Enamel hypocalification and hypoplasia in a dog.
by Brett on Jan.06, 2010, under Veterinary Dental Cases
This 7 month old terrier presented with generalized enamel hypocalcification and hypoplasia. Both the quantity and the quality of the enamel were compromised. Dentin exposure was significant for all teeth. Scaling removed a good portion of the diseased enamel. The remainder was carefully removed with an aluminum oxide bur being careful not to extend past dentin. Dentinal bonding was performed and will need to be repeated periodically to maintain closure of the dentinal tubules to prevent sensitivity and microbe invasion into the pulp.

Dog with Persistent Suborbital Abscess
by Brett on Dec.24, 2009, under Veterinary Dental Cases
This is Lexie. She was treated with antibiotics only to have the abscess recur over the weeks prior to presentation. The tooth and gum tissue looks fairly normal. The x-ray shows a decrease in the periapical bone density on the fourth premolar. The right first molar has an obvious periapical lucency on the palatal root. Those two teeth and the second molar were extracted. Lexie came back Jan13th for her recheck. The suborbital lesion has healed.

This tooth doesn't appear too diseased.
