Cross bite – Orthodontic Matters Episode 7

Our new vlog episode on Orthodontic Matters.

True bilateral cross bite, is very rare, but do exist. Most cross-bites are uni-latarel with a functional shift. There are cases where there is a true bilateral cross bite exists. It is important to we distinguish between uni and bi lateral cross-bites, so we can properly treat it.

Functional shift and TMJ adaptation

Many doctors often ask about how to diagnose functional shift, and how to treated these patients with TMJ problems. Some of these patients’ TMD symptoms and asymmetry are a result of adaptational growth of the condylar head, that had occurred from a functional shift that often resulted from a unilateral cross bite.

In another word, a narrow upper arch often causes a unilateral posterior cross bite, that creates a functional shift, that puts pressure on one of the condylar heads, resulting the mandible being forced to deviate often to the cross bite side. The pressure and force that results from this unilateral deviation, causes one of the condylar heads to grow more than the other, resulting in a asymmetrical mandible.

This study talks about the splint diagnosis and treatment of these cases.

 

Literature review: Mandibular advancement improves the middle airway

Mandibular advancement improves the middle airway:
Great article showing, that advancing the mandible provides an improved middle airway vs with using a cervical headgear. Not a huge surprise, but it’s nice to have hard evidence. They also showed that, there was an improvement in airway size with mandibular advancement vs with untreated control; so the results are not from natural growth. It is worth the read… https://www.ncbi.nlm.nih.gov/pubmed/28863917
