The purpose of the present study was to clarify the prevalence and degree of root resorption induced by orthodontic treatment in patients with and without open bite. One hundred and eleven patients treated with multibracket appliances were retrospectively selected from the patients and divided into non-open bite (NOB) and open bite (OB) groups. The severity of root resorption and the root shape...

Periodontal disease is caused by a necessary association of bacteria and other risk factors. The open bite malocclusion determined by mouth breathing condition could be one of the risk factors that aid bacteria to induce a local periodontal disease in the anterior teeth by a mechanism that was analyzed in this article. One hundred and twenty adult patients of both genders presenting an open b...

Open bite has fascinated Orthodontics due to the difficulties regarding its treatment and maintenance of results. This anomaly has distinct characteristics that, in addition to the complexity of multiple etiological factors, have aesthetic and functional consequences. Within this etiological context, several types of mechanics have been used in open bite treatment, such as palatal crib, orthope...

OBJECTIVE To review the etiology and pathogenesis of anterior open bite malocclusion. DATA SOURCE Review of literature was affected through Pubmed, Google scholar and Science direct. References identified from articles found from the primary search were also reviewed. STUDY SELECTION Published data on etiology and pathogenesis of anterior open bite over the last five decades (1960-2009) wer...

A case of a patient with a fracture of the temporomandibular joint (TMJ) disk is reported. The patient presented with posterior bilateral open-bite and difficulty to chew due to lack of contact between the posterior teeth. Diagnosis of disk fracture of the right TMJ was made based on magnetic resonance imaging (MRI), with posterior displacement of the posterior fragment of the disk, causing the...

INTRODUCTION Non-nutritive sucking habits can cause occlusal alterations, including anterior open bite. However, not all patients develop this malocclusion. Therefore, the emergence of AOB does not depend on deleterious habits, only. OBJECTIVE Investigate a potential association between non-nutritive sucking habits (NNSHs), anterior open bite (AOB) and facial morphology (FM). METHODS 176 ch...

Modinagar.U.P (M) 09910930544 [email protected] Abstract Class III malocclusion associated with skeletal anterior open bite pattern in adults can be a challenging orthodontic problem, especially if treated nonsurgically. Conventionally, several treatment alternatives are available such as tooth extraction, molar intrusion, and absolute anchorage system or orthognathic surgical corre...

In the title complex, [Ru(C6H14O2PS2)3], the coordination environment of the Ru(III) atom is distorted octa-hedral, defined by six S atoms from three S,S'-bidentate diisopropyl di-thio-phosphate ligands. The average Ru-S bond length is 2.41 (1) Å and the average S-Ru-S bite angle is 81.13 (19)°.
