Changes of alveolar bone dehiscence and fenestration after augmented corticotomy-assisted orthodontic treatment: a CBCT evaluation
ConclusionsFor skeletal class III patients, augmented corticotomy-assisted orthodontic treatment is a promising method of improving alveolar bone dehiscence and fenestration for lower anterior teeth, and it also has the potential to protect both lower and upper anterior teeth against dehiscence.

Secondary alveolar bone grafting using autologous versus alloplastic material in the treatment of cleft lip and palate patients: systematic review and meta-analysis
ConclusionAutologous bone and rh-BMP2 graft showed a similar effectiveness in maxillary alveolar reconstruction in patients with unilateral cleft lip and palate assessing bone graft volume and height although rh-BMP2 graft showed a relative shorter length of hospital stay (high uncertainty level).

Effects of impaction severity of treated palatally displaced canines on periodontal outcomes: a retrospective study
ConclusionsRadiographic variables asα-Angle andd-distance seem to not influence the periodontal outcome of the treated impacted canine regardless of the amount of gravity. On the contrary,S-sector might play a significant role when higher rates of gravity are present suggesting the possibility in few cases for periodontal damage at the end of treatment.

Clinical performance of uncoated and precoated polymer mesh base ceramic brackets
ConclusionThe operator-coated InVu brackets demonstrated a lower failure rate when compared to the Readi-Base eXact pre-applied adhesive InVu brackets. The debonding procedure was safe for both bracket types. (Source: Progress in Orthodontics)

A finite element analysis of the effects of archwire size on orthodontic tooth movement in extraction space closure with miniscrew sliding mechanics
ConclusionsWhen decreasing the archwire size, a play of the archwire-bracket slot, as well as the elastic deformation of the archwire, resulted in lingual tipping of the incisors. This tipping led to extrusion of the incisors. (Source: Progress in Orthodontics)

Maxillofacial morphological factors related to acceleration of maxillary growth attributed to facial mask treatment: a structural superimposition study
ConclusionsStructural superimposition analysis showed that counter-clockwise rotation of the maxilla and changes in the distance from the pterygomaxillary fissure to the maxillary anterior alveolus responded most to the orthopedic force of facial mask treatment. The analysis implicated that the pterygoid fissure –palatine’s pyramidal process conjugation responds most to facial mask treatment among maxillofacial sutures and conjugation, and that the difference in the response induces maxillary counter-clockwise rotation.

The mechanical behavior of as received and retrieved nickel titanium orthodontic archwires
ConclusionsThe aging of NiTi archwires influences the force constancy expressed. The behavior of the wires changes depending on the size, brand, and type of retrieval protocol. In terms of performance, the poorest is represented by all wires retrieved in vitro and in vivo group C2 (moderate to severe crowding). (Source: Progress in Orthodontics)

Three-dimensional soft tissue analysis of the face following micro-implant-supported maxillary skeletal expansion
ConclusionsThere are significant changes in paranasal, upper lip, and at both cheeks following expansion using MSE with greater magnitude at the cheeks area. Those changes do not relapse after 1 year (p < 0.05). (Source: Progress in Orthodontics)

New application of dynamic magnetic resonance imaging for the assessment of deglutitive tongue movement
ConclusionsSegmented cine-MR imaging combined with static MR images is useful for assessing soft tissue motion during deglutition. This method is particularly useful in dentistry to evaluate the relationship between tongue function and maxillofacial morphology in terms of orthodontic treatment and orofacial myofunctional therapy, and for improving tongue movement during speech therapy.

Gender and growth variation in palatal bone thickness and density for mini-implant placement
ConclusionsThere exists a definite gender and growth variation in the PBT and PBD in different parts of the palate. Palatal bone thickness between the males and females revealed that the males had significantly higher PBT than the females. (Source: Progress in Orthodontics)

Comparison of piezocision and discision methods in orthodontic treatment
ConclusionsThis is the first clinical orthodontic study to assess the effect of discision on the rate of orthodontic tooth movement. Discision is comparable to piezocision in terms of tooth movement acceleration, pain level, and periodontal status. The discision seems to be effective in reducing the time of orthodontic treatment.

Early Class III treatment with Hybrid-Hyrax -Facemask in comparison to Hybrid-Hyrax-Mentoplate – skeletal and dental outcomes
ConclusionBoth treatments achieve comparable rates of maxillary protraction, without dentoalveolar side effects. Skeletal anchorage with symphysial plates in the mandible provides greater vertical control and might be the treatment of choice in high angle patients. (Source: Progress in Orthodontics)

Zygomaticomaxillary modifications in the horizontal plane induced by micro-implant-supported skeletal expander, analyzed with CBCT images
ConclusionsIn the horizontal plane, the maxillary and zygomatic bones and the whole zygomatic arch were significantly displaced in a lateral direction after treatment with MSE. The center of rotation for the zygomaticomaxillary complex was located near the proximal portion of the zygomatic process of the temporal bone, more posteriorly and more laterally than what has been reported in the literature for tooth-borne expanders. Bone bending takes place in the zygomatic process of the temporal bone during miniscrew-supported maxillary expansion. (Source: Progress in Orthodontics)
