Maxillary prognathism, also known as upper jaw protrusion or overbite, is a condition where the upper jaw is positioned too far forward, causing the upper teeth to overlap significantly with the lower teeth. This article aims to provide a comprehensive overview of maxillary prognathism, including its types, causes, symptoms, diagnostic tests, treatments, surgeries, preventions, and when to seek medical advice.

Types:

1. Skeletal Maxillary Prognathism: Caused by skeletal discrepancies in the size and position of the upper jaw.
2. Dental Maxillary Prognathism: Resulting from dental misalignment rather than skeletal issues.

Causes

1. Genetic Factors: Inherited traits can predispose individuals to maxillary prognathism.
2. Childhood Habits: Persistent thumb sucking or prolonged use of pacifiers can affect jaw development.
3. Environmental Factors: Poor nutrition during critical growth periods can influence jaw development.
4. Hormonal Imbalance: Hormonal fluctuations during puberty may impact jaw growth.
5. Trauma: Facial injuries can alter the position of the upper jaw.
6. Tumors: Abnormal growths in the maxillofacial region can affect jaw alignment.
7. Congenital Conditions: Conditions like cleft lip and palate may contribute to maxillary prognathism.
8. Dental Issues: Malocclusion or misalignment of teeth can lead to overbite.
9. Bruxism: Teeth grinding can exert pressure on the jaw, affecting its position.
10. Temporomandibular Joint Disorders: Dysfunction of the jaw joint can affect jaw alignment.
11. Chronic Mouth Breathing: Habitual mouth breathing can influence facial development.
12. Craniofacial Syndromes: Genetic syndromes like Apert syndrome or Crouzon syndrome may involve maxillary prognathism.
13. Tongue Thrusting: Forceful tongue movements against the teeth can impact jaw position.
14. Sleep Apnea: Obstructive sleep apnea can contribute to abnormal jaw growth.
15. Prolonged Bottle Feeding: Improper bottle feeding techniques can affect jaw development.
16. Nutritional Deficiencies: Inadequate intake of essential nutrients can impair bone growth.
17. Hormone Replacement Therapy: Hormonal treatments can sometimes affect craniofacial development.
18. Medications: Certain drugs may have side effects that impact jaw growth.
19. Prolonged Pacifier Use: Extended pacifier use beyond infancy can affect oral development.
