Class III malocclusion is characterized by a variety of skeletal and dental components, including a large or protrusive mandible, retrusive maxilla, protrusive mandibular dentition, retrusive maxillary dentition, and combinations of these components .Its diagnosis, prognosis, and treatment have always been a challenge for clinicians .A normal occlusion and improved facial esthetics of. Mandibular mesioclusion (Class 3 malocclusion; MAL/3): The mandible resides mesial (rostral) to its normal location in relation to the maxilla (Photo 6). Although considered normal in brachycephalic breeds, maxillary incisor contact with the lingual floor or canine teeth can cause significant trauma and discomfort CAUSES OF PROGNATISM OR CLASS III AND HOW TO DETECT IT. Prognathism is considered a malformation of eminently genetic causes, although its etiology is still multifactorial.Thus, a combination of inheritance and environment can enhance or decrease malocclusion.. Among the environmental factors involved, we can mention oral habits, hypertrophy of tonsils or adenoids, premature loss of temporary.
Most malocclusion studies to date have focused on Class III malocclusions. Genetic studies for Class II and Class I malocclusion are more rare. An example of hereditary mandibular prognathism can be seen amongst the Hapsburg Royal family where one third of the affected individuals with severe class III malocclusion had one parent with a similar.

Class 2 malocclusion is diagnosed when a severe overbite is present. This condition, known as retrognathism (or retrognathia), means that the upper teeth and jaw significantly overlap the lower jaw and teeth. Class 3. Class 3 malocclusion is also diagnosed when. Class 3 is commonly referred to as underbite, or prognathism (in dental terminology). This type of malocclusion happens when the lower jaw juts forward, causing the lower teeth to overlap the upper teeth
. A crossbite may also appear in class 3 malocclusion as a result of the jaw size discrepancy, tooth size discrepancy or poor tooth alignment Mandibular distocclusion-Overbite (class 2 malocclusion): the lower jaw (mandible) is too short. This is a genetic skeletal deformity. The short jaw can cause the mandibular canine teeth or incisors to traumatize the palate and gum tissue of the maxilla (upper jaw), causing pain and damaging the teeth What is an incisal class III malocclusion? The lower incisal edge occludes anterior to the cingulum plateau of the maxillary incisor. The overjet is reduced or reversed and there may be an anterior mandibular displacement.
