A prospective randomized split-mouth study on pain experience during chairside archwire manipulation in self-ligating and conventional brackets.

Objective: To investigate patient discomfort during archwire engagement and disengagement in patients treated with self-ligating and conventional brackets using a split-mouth design.

Materials And Methods: Eighteen consecutive patients (15 female, 3 male; age: 22.2 ± 6.

Midline correction by asymmetric reciprocal torque: a pilot study.

Objective: Can we correct dental midline discrepancies by systematic torque bends on all canines and premolars without extraction and mesiodistal tooth movement?

Patients And Methods: Eight orthodontic patients (4 males, 4 emales, mean age 31 years) presented a dental midline discrepancy of 2-4 mm, moderate deviation of the chin, no skeletal asymmetry, and a horizontal orientation of the occlusal plane in the frontal aspect. On the side where the mandible was shifted medially, asymmetric torque bends moved the antagonist canine and both premolar crowns buccally, while palatal crown torque was used on the maxillary canine and premolars on the other side. Lingual crown torque corrected the medially shifted canine and premolars in the mandibular dental arch, and buccal crown torque the laterally shifted lower canine and premolars.

The use of a bruxchecker in the evaluation of different grinding patterns during sleep bruxism.

A variety of problems involving the masticatory system can be partially attributed to parafunctional habits such as bruxism. These include occlusal trauma, abfractions, tooth migration, as well as temporomandibular dysfunction. Since bruxism is considered a contributing factor to the above-mentioned dental problems, it is essential to consider parafunctional habits in the diagnosis and treatment planning before doing any occlusal reconstruction.
