Comparison of monozygotic twins who received orthodontic treatment with self-ligated and conventional brackets: Case report
This study objectived to compare the performance of different brackets, conventional and self-ligated, under similar conditions, in monozygotic twins patients with severe tooth crowding. It was evaluated the rapidness of treatment, chair time, quality of finalization, comfort and hygiene of the patients. The treatments had a duration of 24 months in both cases, however, with the conventional appliance, less time was required for performing alignment and leveling. Whereas, treatment with the self-ligated appliance required fewer appointments, and chair time was reduced about 20%. Both patients had satisfactory hygiene, and ...

Lessons learned as a student of craniofacial biology: What this might mean for orthodontic professional education and clinical practice in the 21st century
Publication date: March 2018Source: Orthodontic Waves, Volume 77, Issue 1Author(s): Harold C. SlavkinAbstractThe National Institute of Dental Research (NIDR) supported the international symposium “Congenital Anomalies of the Face and Associated Structures” led by Professor Sam Pruzansky and members of the first Dental Study Section in 1959. The plan was unique in that it examined the human face as a biological continuum, from conception through postnatal growth and development, to maturity in terms of functions, structures, and behavior. The symposium forged foundations for what we now term “craniofacial biology.” ...

Lip changes after premolar extraction in Class I bimaxillary protrusion: A retrospective study in Thai female adults
ConclusionThe ratios of upper and lower anterior teeth retraction and upper and lower lip changes were 1:0.56 and 1:0.87, respectively. The predictive equations of upper and lower lip reductions were ΔH-U-lip = 0.34(ΔH-tUI) + 1.19 and ΔH-L-lip = 0.57(ΔH-cLI) + 2.11, respectively. (Source: Orthodontic Waves)

Corrosion of laser-welded stainless steel orthodontic wires
ConclusionLaser welding of stainless steel orthodontic wires should be acceptable for clinical use, because the joints showed sufficient strength and the original structure was not significantly altered. Immersion in acidic solution had minimal effect on the mechanical performance at the joint regions, and showed minimal acceleration of metallic ion release. (Source: Orthodontic Waves)

Histological response in dental pulp of accelerate tooth movement using periodontal ligament distraction osteogenesis in dogs
ConclusionPLDO enabled rapid tooth movement and initial histological change in the dental pulp was similar to that in response to conventional orthodontic treatment. (Source: Orthodontic Waves)

Considerations for placement of mandibular buccal shelf orthodontic anchoring screw in Class III hyperdivergent and normodivergent subjects – A cone beam computed tomography study
ConclusionThe mesial aspect of the second molar appears to be a safe site for placement of MBS orthodontic anchoring screw as its slope was flatter and gave greater distance from molar root. Increasing vertical level or insertion angle resulted in a higher cortical bone thickness and distance from the molar root. (Source: Orthodontic Waves)

Treatment of severe maxillary hypoplasia with oligodontia and complete bilateral cleft lip and palate by maxillary anterior segmental distraction osteogenesis
We describe successful orthodontic treatment using maxillary anterior segmental distraction osteogenesis (MASDO) in a patient with cleft lip and palate. A 20-year-old woman with bilateral cleft lip and palate, multiple congenitally missing teeth, reduced maxilla, concave soft-tissue profile, and skeletal Class III jaw relationship was treated with a combination of orthodontic treatment and MASDO. After treatment, the anterior maxilla was displaced forward with new bone formation induced in the distraction gap for insertion of dental implants. Maxillary hypoplasia was successfully treated while preserving the velopharyngeal...

A case of adult cleft palate patient treatment with differential maxillary lateral expand distraction osteogenesis using combined expansion appliances
In this report, we suggest a novel method for uneven maxillary lateral expansion using a dento-osseous-supported expansion appliance in the frontal side of the maxilla and a modified dental-supported expansion appliance in the mid-palatal area. With this method, we achieved the optimal maxillary expansion in the maxillary frontal and molar areas. As a result of the surgically-assisted orthodontic treatment, facial asymmetry, the facial midline, and severe malocclusion were corrected. Furthermore, the resulting occlusion and facial symmetry were maintained over a 2-year retention period. Although attention must be paid rega...

Transverse adjustment of preformed stainless steel archwires to the dental arch form
ConclusionTo reduce these adjustments, preformed stainless steel archwires that are designed to be approximately 1–2 mm at the canine, 1–3 mm at first premolar, 2–4 mm at second premolar, and 3–6 mm at first molar wider in the transverse dimension could be clinically recommended.

Questionnaire investigation after orthodontic treatment in patients with unilateral cleft lip and palate: An inter-clinic collaborative study
ConclusionThis study clarified the subjective effects and problems with orthodontic treatment in patients with UCLP in Japan. Satisfaction after treatment was high. Anticipated esthetic improvement was accomplished and masticatory problems improved. Orthodontic treatment also positively affected speech. Efficient orthodontic treatment to minimize treatment duration and improved treatment systems for easier access are needed to reduce patient burdens in Japan. (Source: Orthodontic Waves)
