Palataly-displaced incisors or canines are typically extruded. The crossbite must be corrected without occlusal interference during alignment. Occlusal interference associated with such extrusion can prevent proper tooth positioning, and therefore, the temporary use of a bite plate may be necessary' However, unnecessary bite raising may occur when a bite plate is used in adults, and the patient's discomfort due to such an appliance cannot be ignored. Most of the time, conventional ligation fails and also ends with debonding of the bracket. A slin shot use ofan elastic chain forfaster correction of instanding tooth is suggested.

The human tooth's morphology, which includes variations in cusp numbers and patterns, is of tremendous interest to anthropologists, morphologists, and dentists. Cusp 6 is an additional cusp that is very seldom encountered in primary or permanent mandibular molars, especially first molars. A supernumerary cusp located lingual to the distobuccal cusp at the crown's distal border is cusp 6.

Background: Orthodontic treatment involves manipulation of tooth position that can temporarily lead to occlusal interferences capable of inducing bruxism. The objectives of this study were to determine the self-reported incidence of bruxism and its association with factors such as facial type, divergence, skeletal and dental malocclusions in orthodontic patients.
Materials And Methods: 80 patients who underwent a minimum of six months of orthodontic treatment were surveyed using a validated self-reported bruxism questionnaire for the presence or absence of bruxism.

Background: This case report details a true hemifacial hyperplasia with temporomandibular joint ankylosis case managed through a multidisciplinary approach involving department of oral and maxillofacial surgery, orthodontics, and prosthodontics.
Case Presentation: A 42-year-old female patient presented with a chief complaint of limited mouth opening. Clinically, the patient exhibited severe facial asymmetry due to hyperplasia of the left facial region.

Purpose: Optical tracking devices (OTDs) hold promise for enhancing patient-centered prostheses, but their efficacy remains underexplored. This clinical study aimed to comprehensively evaluate differences in static and dynamic occlusions among occlusal appliances fabricated using optical tracking, conventional tracking, and average articulator values (AAVs), providing insights into their efficacy in clinical and research-based practices.
Materials And Methods: Twelve dentate participants aged over 25 years, with Angle Class I and II occlusal relationships, were enrolled.

Article Synopsis
- The study focuses on the difficulties of designing prosthetic occlusal surfaces that accurately reflect a patient's jaw movements, highlighting the need for precision in avoiding occlusal interferences during lateral excursions.
- It aimed to evaluate the effectiveness of digitally replicating mandibular movements to identify and correct these interferences in CAD-CAM zirconia crowns through two different adjustment methods.
- Results showed that crowns adjusted using only buccal records (Group I) had higher lateral pressure measurements compared to those adjusted with both buccal and lateral records (Group II), suggesting that the latter may lead to better occlusion outcomes.
