What Is Excessive Vertical Overlap of Front Teeth?
When a patient presents with excessive vertical overlap of the front teeth, the condition is clinically known as deep bite (Class II Division 1 malocclusion) . This occurs when the upper front teeth cover the lower front teeth to an abnormal degree, often resulting in a pronounced "overbite." While some vertical overlap is normal, excessive c...
What Is a Reverse Overbite?
A reverse overbite, also known as anterior crossbite , occurs when the lower (mandibular) teeth protrude past the upper (maxillary) teeth when the jaws are closed. This misalignment primarily affects the front teeth but can also involve the posterior (back) teeth. While it may seem like a minor dental concern, it can significantly impact oral function, aesthetics, ...
Alternative plan

Headgear therapy is another alternative, although it is not suggested in this case since it has a restraining effect on the maxilla, whereas repositioning the mandible would enhance the facial profile more. Twin Block was chosen over Activator because to increased patient...
Model study revealed a missing upper left central incisor, which is linked to space loss (3 mm), and a little crowded lower arch (4 mm). The patient's occlusion included a 7 mm overjet, an average and incomplete bite on the palatal mucosa, and midlines that coincided between the upper and lower teeth. Special examinations of the upper incisors revealed normal tooth color and normal cold and percus...
