Excellent for oroscopy of mandibular cheek teeth. 
As we realise that the most critical part to performing high quality dentistry in horses depends largely on performing a thorough examination, the arcade speculum becomes a much more necessary piece of equipment.
With the arcade speculum in place, it keeps the tongue and cheeks away from the teeth, allowing better visualisation of the lingual and buccal sides of the cheek teeth, the gingival margins and interproximal spaces. 
Great for use in doing periodontal treatment.
It can also be used as a cheek retractor for demonstrating problems to clients.
Comes with a 5-year warranty.
