Anterior open bite caused by?
- A. Unilateral condylar fracture.
- B. Bilateral condylar fracture.
- C. Lefort II.
- D. Zygomatic fracture.
Based on the information provided, the most likely cause of an anterior open bite is: B. Bilateral condylar fracture.
Here's why:
- Unilateral condylar fracture:
This can cause an open bite on the side of the fracture, but not necessarily an anterior open bite involving both front teeth.
- Lefort II:
This fracture involves the midface and can cause an open bite, but it typically affects the upper jaw as a whole, not just the front teeth.
- Zygomatic fracture:
This fracture affects the cheekbone and doesn't directly cause an open bite.
- Bilateral condylar fracture:
This fracture affects both condyles, which are the jaw joints located near the front of the ears. When both condyles are fractured, the mandible (lower jaw) can be displaced backward, leading to an anterior open bite where the front teeth don't touch.
However, it's important to note that this is just a general answer based on the information given. Diagnosing the cause of an anterior open bite requires a thorough examination by a qualified healthcare professional, such as a dentist or orthodontist. They will consider various factors, including the patient's history, symptoms, and X-rays, to determine the specific cause and recommend the appropriate treatment.
