A 16-month-old spayed female Burmese was referred, because, since it was a kitten, its jaws would frequently lock closed while eating. The cat was fed both dry kibble and canned food. Bilateral supernumerary maxillary fourth premolar teeth, palatal to the normal maxillary fourth premolar teeth (), had resulted in a bilateral class one malocclusion. Buccoversion of both mandibular molar teeth had occurred (), with these teeth occluding laterally with the maxillary fourth premolar teeth (). Supernumerary maxillary third incisor teeth were also diagnosed (). These teeth were not causing crowding and were deemed to be stable; therefore, they were not extracted. In order to relieve the jaw locking, both supernumerary maxillary fourth premolar teeth and both mandibular molar teeth were extracted using the open extraction technique. At the follow-up examination the owner stated that the cat’s jaws no longer locked while eating.
A 19-month-old spayed female Burmese, a littermate of case 1, was presented with a primary complaint of halitosis. Both cats were fed a raw diet and had not shown any changes in eating behaviour. Oral examination revealed bilateral supernumerary maxillary fourth premolar teeth and a supernumerary left mandibular fourth premolar tooth (SN 108, SN 208, SN 308), with associated PD3 and moderate generalised gingivitis. The supernumerary maxillary fourth premolar teeth were also situated palatal to their normal counterparts (), while SN 308 was moderately rotated and situated between 308 and 309 (). PD3 was also diagnosed at 209. Tooth 209 was extracted using the closed extraction technique, and SN 108, SN 208 and SN 308 were extracted using the open extraction technique (). The SN 108, SN 208 and 209 extraction sites were allowed to heal by second intention ().
