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.
Root canal and crown prep for canine tooth in a dog
by Brett on Dec.16, 2009, under Veterinary Dental Cases
This patient had what appears to be a normal right mandibular canine tooth. The left mandibular canine was fractured with pulp exposure. The radiograph shows root resorption and a large pulp cavity with a periapical lucency. Periapical changes are also present on the right mandibular canine tooth. The final root canal procedure, the crown prep and crown placement are demonstrated.

The right mandibular canine (top) has a smaller pulp cavity than the left. Periapical lucencies are present on both. The left canine is undergoing apical root resorption as well. The left tooth had exposed necrotic pulp.
Although the right canine is fine on gross examination the pulp on this tooth is also necrotic.
Root canal therapy is the treament of choice.
The tooth is prepared with a chamfer margin and a detailed impression made and sent to the lab from crown fabrication.
A cast metal alloy crown is placed at the next visit to complete the procedure.
Fistula in a Dog Associated with the maxillary fourth premolar abscess
by Brett on Dec.10, 2009, under Veterinary Dental Cases
This dog has a fistula associated with the left maxillary fourth premolar tooth.
Brett Beckman, DVM, FAVD, DAVDC, DAAPM
The pulp is exposed and the tooth is non-viable in the middle aged dog
The fistula can be seen associated with the distal root
The bone loss is evident and the apical portion of the root is resorbing
The radigraph demonstrates the lucencies in the bone

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.
Brett Beckman, DVM, FAVD, DAVDC, DAAPM
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.
