Skeletal Maxillary Prognathism, also known as prognathism or protrusion of the upper jaw, is a condition where the upper jaw protrudes beyond the lower jaw. This article aims to explain this condition in simple terms, covering its types, causes, symptoms, diagnostic tests, treatments, preventive measures, and when to seek medical advice.
Types of Skeletal Maxillary Prognathism:
