Abstract:

Oral Biology<br>M.S.<br>Objective: Malocclusion is a complex musculoskeletal trait, with muscle playing an integral role in vertical facial development. A single nucleotide polymorphism (SNP) produces the R577XX nonsense mutation in the alpha-actinin-3 (ACTN3) gene, creating a stop codon and loss of its protein. With loss of ACTN3, alpha-actinin-2 (ACTN2) is upregulated. Calsarcins, known inhibitors of calcineurin activation, preferentially bind ACTN2 leading to a surge in free calcineurin. The increase in calcineurin activity produces the phenotypic shift of fast muscle fibers toward the slow

Title: BOS Orthognathic DVD: RCT assessing patients’ knowledge and satisfaction Objectives: To compare patients’ knowledge of orthognathic treatment and satisfaction with their multi-disciplinary clinic consultation, after receiving information in a standard format versus standard format plus BOS Orthognathic DVD. Design: Multi-centred, randomised controlled trial. Setting: Multi-disciplinary orthognathic clinics at four hospitals in Merseyside, UK. Participants and Methods: 106 participants, age > 16 years, attending their first multi-disciplinary orthognathic clinic, were given information o

Abstract:

Oral Biology<br>M.S.<br>Temporomandibular disorders (TMD) are comorbid conditions. Most are related to anxiety-induced muscular pain, but some are associated with facial asymmetry resulting from condylar resorption (CR) or condylar hyperplasia (CH). The etiology of the most common forms of CH and CR are still unknown. CR can be caused by rheumatoid arthritis (RA) or more commonly osteoarthritis (OA) of the TMJ, and inflammatory mediators have been previously implicated. Previous studies have identified pain/inflammatory genes related to chronic TMD while others have demonstrated potential gene

Abstract:

Abstract Considerable amounts of research have been done on various aspects of orthognathic surgery during its short history. Nevertheless, there are no comprehensive publications on the cost-risk-benefit analysis of the entire process of orthognathic surgery. The purpose of the present study was to evaluate the psychosocial and biophysiological outcomes of orthognathic surgery with special reference to complications and financial costs. The study series consisted of patients referred for consultations and treatment of dentofacial deformities and involved a total of 953 patients and 20 contr

La presente tesis doctoral es un compendio de 4 publicaciones sobre los cambios posicionales y morfológicos que ocurren en la articulación temporomandibular tras la realización de cirugía ortognática. Del estudio de campo realizado se concluye que se producen cambios estadísticamente significativos en la posición del cóndilo articular tras la cirugía de avance mandibular. Adicionalmente se valida la utilización de la tomografía computerizada de haz cónico para el estudio morfológico y posicional de la articulación temporomandibular.

The results of the study concluded that the identification of the patient's personality profile was unable to predict those patients who would not have a successful perception of the outcome of surgery, mirroring the findings of Pogrel and Scott (1994) who found that it was impossible to identify the 'psychologically bad-risk' orthognathic patient.

Abstract:

Oral Biology<br>M.S.<br>Objective: Obstructive sleep apnea (OSA) is defined by recurrent breathing cessations accompanied by a collapse of the pharyngeal airway. Co-morbid conditions include obesity, cardiovascular disease, diabetes, and in some cases, retrognathia and muscle dysfunction. The latter two conditions may prompt orthognathic correction. Past investigations have shown a genetic association with OSA. Given that masseter muscle influences skeletal malocclusion and is active during OSA, we investigated whether the expression of OSA-associated genes is altered in a Class II open bite O
