Effects of Oral Appliances for Obstructive Sleep Apnoea in Reduced Periodontium: A Finite Element Analysis.

Background And Objective: In the literature, no studies correlate the effects of mandibular advancement devices (MADs) with different titration systems to periodontitis. Through a finite element analysis (FEA), this study investigates the effects generated on periodontal ligaments (PDLs) and teeth by four commercial MADs in periodontal health and with 15% bone resorption.

Methods: Four MADs (Somnodent Flex™, Somnodent Avant™, Orthoapnea™, and Herbst™) were digitalised starting from the impressions of a patient's dental arches.

Patients' perceptions of the importance of improvements and side effects from mandibular advancement device therapy for obstructive sleep apnea and snoring.

Objective: To assess which improvements and side effects are considered most important by patients with OSA treated with a MAD.

Methods: A specific questionnaire consisting of 20 questions, including 10 questions on improvements and 10 on side effects, was developed and mailed to all subjects (54).

Results: 42 patients, participated in the survey by answering the questionnaire.

Assessment of Oral Health in a Child Cohort of a Rural Zone of Ethiopia.

Health conditions in a developing state such as Ethiopia are precarious; in addition to the extreme spread of infectious diseases such as AIDS, oral health is also affected by the scarce knowledge and possibility of treatment. This analysis considered 77 children aged 7 to 11 from a primary school in Guraghe in Ethiopia. The presence of plaque, calculus, and caries was evaluated.

Difference in Using Protrusion Face Mask before or after Rapid Palatal Expansion in Skeletal Class III Children: A Preliminary Study.

Treatment of third-class malocclusions often presents a challenge for orthodontists. Skeletal disharmony is often associated with dental malposition. There are several therapeutic choices, including the use in combination of transverse expansion of the maxilla with rapid palatal expander (RPE) and posterior-anterior traction with a Delaire face mask (FM).

Periodontal effects of two Somnodent oral devices for the treatment of OSA: A finite element study.

Objective: The study aims to evaluate the stresses and the deformations generated at the periodontal level by two mandibular advancement devices (MADs) using finite element analysis.

Methods: A three-dimensional digital model of the skull of a 29-year-old patient was created using a CBCT. The 3D models of two MADs (Somnodent Flex and Somnodent Avant) were reconstructed from scanning prototypes based on the patient's anatomy.

Validity of the STOP-Bang Questionnaire in Identifying OSA in a Dental Patient Cohort.

Obstructive Sleep Apnea represents a widespread problem in the population, but it is often not diagnosed and not considered a true pathology. Different diagnostic tools are available for the diagnosis of sleep apnea. This study aims to demonstrate the ability of the STOP-Bang (Snoring, Tiredness, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, and Gender) questionnaire in identifying subjects with Obstructive Sleep Apnea (OSA) Syndrome, highlighting the role of dentists as epidemiological sentinels.

Combined orthodontic and surgical treatment supported by virtual planning in a severe mandibular asymmetry: A case report.

This article describes the complex dental treatment of a 17-year-old girl with skeletal Class I, severe mandibular asymmetry, maxillary retrusion, normodivergent pattern, left canine and molar Class II, canting of the occlusal plane, lateral left cross-bite, deep bite, upper and lower incisors retrusion and an increased curve of Spee. To achieve optimal results, a multidisciplinary approach to treatment was adopted involving orthodontics and maxillofacial surgery. The surgical phase was supported by virtual surgical planning with dedicated software.
