26 Dental Tribune Middle East & Africa Edition | September-October 2014news Crown for the queen of the jungle By Sirona B ensheim, Germany: Spectacular dental proce- dure on a big cat in Den- mark: The CEREC CAD/CAM technology was actually devel- oped for humans but was suc- cessfully used for the first time on a lioness in a Danish zoo. After Danish zoos received nega- tive headlines in the press over the past few months, one Dan- ish zoo is now attracting positive attention – with a spectacular dental procedure. The damaged carnassial tooth of a lioness in Ree Park Safari in Ebeltoft (near Aarhus) was restored using the CAD/CAM system CEREC. The Danish zoo wanted to use the benefits of the chairside system, which allows treatment in just one session, for its animal pa- tient. No second anesthesia required The veterinary team was faced with a few challenges when op- erating on the 12-year-old Afri- can lioness Naomi. Adult lions cannot be anesthetized for more than two to three hours, mean- ing that the entire procedure needed to be completed in that period of time. Since extracting such a large tooth is difficult and lions need the carnassial tooth to be able to bite, a root canal treat- ment was carried out and the tip of the carnassial tooth was fitted with a crown. The CEREC meth- od allowed the entire treatment to be successfully completed in just a single procedure. “Anes- thesia is very stressful for wild animals. This was unavoidable for the root canal treatment but we did not want to put Naomi through it a second time to fit the crown,” says vet Jens Ruhnau, who led the operation. Naomi recovered from the operation quickly without any complica- tions and is now back to her old self. State-of-the-art technology for wild animals Treating such a big cat shows the universality of CEREC. “The clear advantage of using CEREC since it requires only one pro- cedure to take a digital impres- sion of the tooth and carry out the restoration is beneficial not only for humans,” says Birgit Möller, Head of Product Man- agement CEREC at Sirona. After treatment was successfully com- pleted, all those involved were clearly relieved. “It was a fasci- nating procedure and I am sure that it will not be the last time we use state-of-the-art technol- ogy like CEREC to improve the lives of our animals,” said Jesper Stagegaard, the director of Ree Park.
