Objective: To evaluate the efficacy of mandibular advancement device as a treatment of mild to moderate obstructive sleep apnoea and to evaluate the change in upper airway space volume by using cone beam CT (CBCT).
Study Design: In vivo observational study. Place and Duration of the Study: Department of Prosthodontics, Crown and Bridge, Sri Aurobindo College of Dentistry, Indore (M.P), India, from March 2017 to January 2021.
Methodology: Patients with mild to moderate obstructive sleep apnoea patients using Berlin questionnaire were selected. Pre- and posttreatment-CBCT analysis was done to compare the changes in superior and inferior upper airway space before and after using mandibular advancement device. The pre and postoperative CBCT were also compared using a paired t-test for the quantitative variables. After two months, the patients were asked to complete a self-administered questionnaire to assess their sleep improvement, initial symptoms regression, and effectiveness of the mandibular advancement device.
Results: On comparative evaluation of the pre- and post-CBCT, the mean score before the mandibular advancement device placement was found to be 7.77+2.79 cc, whereas the mean score after the mandibular advancement device placement was found to be 9.75+3.34 cc (p<0.001). Significant volumetric change was seen in upper airway space after receiving treatment for the two months. The patient noticed a substantial improvement in their sleep as well as a reduction in the original symptoms.
Conclusion: This study showed statistically significant volumetric change in the upper airway space and reduction in their symptoms after treatment with the mandibular advancement device (MAD).
Key Words: Obstructive sleep apnoea syndrome (OSA), Continuous positive airway pressure (CPAP), Cone beam computed tomography, Mandibular advancement device (MAD), Upper airway volume.

Objectives: The presented study aimed to evaluate the effect of mandibular protrusion with a temporarily applied mandibular advancement device (MAD) on the posterior airway space and to determine a reliable metric constant based on a three-dimensional computed tomography (CT) evaluation.
Materials And Methods: The study population consisted of patients with oral squamous cell carcinoma who were treated at least six months prior to the follow-up CT in supine position. Each patient received an individually adjusted MAD that was temporarily applied with three different protrusion distances (P = 0 mm, P = 4 mm, and P = 8 mm) during follow-up CT.
Objectives: To examine tooth root length and root volume in cone beam computed tomography (CBCT) images in patients with skeletal Class II and III anomalies who have undergone single-jaw (SJ) and double-jaw (DJ) orthognathic surgery, and to compare the changes between jaws with and without osteotomy.
Materials And Methods: This study was conducted on the archive records of a total of 60 adults: 36 women and 24 men with an average age of 21.1 ± 3.

Obstructive sleep apnoea (OSA) is a sleep-related breathing condition that involves the presence of episodic disruptions to the sleeping pattern due to partial or complete airway obstruction. There are a range of treatment options that exist to alleviate the symptoms of this condition including CPAP, mandibular advancement, and maxillary expansion techniques. This systematic review and meta-analysis of published articles aims to determine if rapid maxillary expansion ("RME") is an effective treatment option in the management of OSA, using quantitative parameters of AHI and SpO.

This study aimed to assess the changes in the position and size of articular spaces and anteroposterior and mediolateral condyle dimensions following orthognathic surgery. Additionally, it evaluated the correlation between these changes and mandibular movement during surgery. This experimental study examined 31 patients (16 with Class III and 15 with Class II malocclusions) who were candidates for orthognathic surgery.

This novel hybrid single-double-single barrel (1-2-1) design for fibula free flap reconstruction addresses the unique challenges presented by Brown Class III mandibular defects, which involve long-span defects at both bodies of the mandible and the chin. The importance of this design lies in its ability to overcome the limitations of traditional approaches in terms of mandible height and pedicle length, while optimizing both functional and esthetic outcomes.The technique utilizes a combination of single-double-single barrel fibula segments to achieve ideal esthetics and support for dental prosthesis across different areas of the mandible.
