Bruxism is excessive teeth grinding or jaw clenching. It is an oral parafunctional activity; [1] i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common behavior; the global prevalence of bruxism (both sleep and awake) is 22.22%. [2]
The mechanism of this tooth movement is that the splint effectively holds some teeth out of contact and puts all the force of the bite onto the teeth which the splint covers. This can cause the covered teeth to be intruded, and those that are not covered to over-erupted. I.e. a partial coverage splint can act as a Dahl appliance. Examples of ...

It is estimated that nearly 30% of the general population present with malocclusions that are in great need of orthodontic treatment. [1] However, the term dentofacial deformity describes an array of dental and maxillo-mandibular abnormalities, often presenting with a malocclusion, which is not amenable to orthodontic treatment alone and definitive treatment needs surgical alignment of upper ...
Due to the discrepancy between the maxillary and mandibular arch, neuromuscular guidance of the mandible causes mandible to shift towards the side of the crossbite. [14] This is also known as Functional mandibular shift. This shift can become structural if left untreated for a long time during growth, leading to skeletal asymmetries. Unilateral ...
