Oral Surgical Preparation and Bone Augmentation

Play an AI-generated podcast conversation about this lesson

What is the primary reason orthodontic treatment may not be practical for some patients?

Insufficient alveolar bone to support extruded teeth

Poor prognosis of teeth preventing extraction

Malposed teeth that cannot be repositioned surgically

Lack of teeth for anchorage of the orthodontic appliance (correct)

What is the consequence of extruded teeth on the surrounding alveolar bone?

The alveolar bone will remain unaffected

The alveolar bone will be resorbed apically

The alveolar bone will be carried occlusally (correct)

The alveolar bone will be augmented

Why should all impacted teeth be considered for removal?

Because they are equally problematic in edentulous areas or adjacent to abutment teeth (correct)

Because they may cause occlusal discrepancies

Because they may lead to malpositioning of adjacent teeth

Because they are severely malposed
