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.
The vestibular aspect of the right mandible, screw placement
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.

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.
Radiography confirms severe periodontal disease.
Additional Images of the Previous Patient with Canine Tooth Resorption
by Brett on Dec.01, 2009, under Veterinary Dental Cases
This is the same patient from the prior post. This is an example of Type I tooth resorption on the mesial root and Type II resorption on the distal root.

This 3rd mandibular premolar has very subtle swelling of the gingiva distal to the crown
Radiographically you can see the periodontal ligament space on the mesial root classifying this as type I tooth resorption. This requires full root extraction. In the distal root the space is not present and bone is replacing the rooth. In this case crown reduction of more specifically here partial tooth extraction may be performed to remove tooth to the point where only bone is present. This requires extensive experience and a very high powered head surgical magnifyer to perform properly.
