Prognathism
Also known as: Underbite · Mandibular Prognathism · Vorbiss · Hechtgebiss · Class III Malocclusion
Overview
What it is
Prognathism, commonly known as an undershot jaw, is a skeletal malformation of the skull where the lower jaw grows longer than the upper jaw. This structural imbalance affects the dental and skeletal systems, preventing the upper and lower teeth from aligning into a normal bite. The condition is polygenic, meaning it is influenced by multiple genes, and is diagnosed through a thorough examination of the oral cavity.
How it presents
Owners will typically notice the lower front teeth protruding past the upper teeth as the puppy's teeth develop, usually by a few months of age. While many dogs show no discomfort, more severe cases can cause difficulty chewing, uneven wear on the teeth, or irritation to the gums.
Treatment
Mild cases often require no treatment at all. If the misalignment causes pain or eating difficulties, corrective procedures such as tooth extractions or orthodontic adjustments can resolve the issue, with one-time costs ranging from 150 to 1500 EUR.
