Finite element study of controlling factors of anterior intrusion and torque during Temporary Skeletal Anchorage Device (TSAD) dependent en masse retraction without posterior appliances: Biocreative hybrid retractor (CH-retractor).
CONCLUSIONS: With the CH-retractor, varying the size of the NiTi archwire and/or varying the amount of gable bend on the SS archwire affects control of the anterior teeth during en masse retraction without a posterior appliance.

kVp, mA, and voxel size effect on 3D voxel-based superimposition.
CONCLUSIONS: Using different CBCT settings can affect the accuracy of the voxel-based superimposition method. This is particularly the case when using low kVp values, while changes in mA or voxel sizes did not significantly interfere with the superimposition outcome.

Post-gel shrinkage, elastic modulus, and stress generated by orthodontic adhesives.
CONCLUSIONS: Post-gel shrinkage of orthodontic adhesives was comparable with restorative composites, which are known to create shrinkage stresses in restored teeth. FEA indicated that this shrinkage creates stresses in the adhesive and in the enamel around the brackets. PMID: 31545075 [PubMed - as supplied by publisher] (Source: The Angle Orthodontist)

Twenty-year follow-up of functional treatment with a bionator appliance: A retrospective dental cast analysis.
CONCLUSIONS: 20 years after bionator treatment without additional fixed appliances, the improved sagittal relationship and the reduced overjet and PAR index remained fairly stable. Long-term changes are most likely due to physiological aging processes and are not associated with bionator treatment.

Three-dimensional analysis of lip changes in response to simulated maxillary incisor advancement.
Abstract OBJECTIVE: To assess the immediate response of lips in three dimensions (3D) resulting from simulated maxillary incisor advancement. MATERIALS AND METHODS: Incremental maxillary incisor advancement was simulated by placing wax of increasing thickness (+2 mm, +4 mm, +6 mm) on the incisors of 20 participants, and the induced lip changes were recorded using 3D stereophotogrammetry. The induced displacement of lip landmarks was quantified using 3D image analysis software. Data were analyzed using a repeated-measures analysis of variance (ANOVA) after adjusting for age and sex of the study participants. ...

Evaluation of objective and subjective treatment outcomes in orthodontic cases treated with extraction of a mandibular incisor.
CONCLUSIONS: There were no significant differences in the treatment outcomes of orthodontic cases treated with MIE or NE, indicating that MIE is a valid treatment option. A wax setup is moderately correlated with posttreatment results. Both laypeople and dental students rated posttreatment dental attractiveness higher than pretreatment in MIE and NE groups. Dental students tended to be more critical than laypeople in their ratings. PMID: 31187629 [PubMed - as supplied by publisher] (Source: The Angle Orthodontist)

Orthodontic management of a complete and an incomplete maxillary canine-first premolar transposition.
Abstract Maxillary canine and first premolar transposition is a complicated dental anomaly to treat, especially if the clinician's goal is to orthodontically move the canine into its normal position. Early diagnosis with cone-beam computed tomography simplifies the treatment of this pathology. This case report describes a patient with bilateral transposition, one complete and the other incomplete, involving the maxillary canine and the first premolar (Mx.C.1P). The orthodontic treatment involved the correction of both transpositions. In the complete transposition, the traction was mesial and upward to move the can...
