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 6-year-old castrated male Burmese was presented as the referring veterinarian had noted supernumerary teeth on oral examination. On referral, SN 108, SN 308 and SN 408 were confirmed. The SN 408 was shown to have a supernumerary third root on radiographs. The supernumerary root was slender and situated between the mesial and distal roots (). The SN 108 was positioned palatal to the normal 108 () and the SN 308 and SN 408 were positioned lingual to the normal mandibular fourth premolar and molar teeth, causing moderate rotation of the adjacent normal mandibular teeth; 108, 109, SN 108, SN 308 and SN 408 were affected by PD3. Closed extraction was performed at 109. The open extraction technique was used for the extraction of SN 108, SN 308, SN 408 and 108.
