Adult patient with bilateral cleft lip and palate treated using bone graft followed by lateral distraction: A case report
Publication date: Available online 8 November 2018Source: Orthodontic WavesAuthor(s): Ayaka Oka, Chihiro Tanikawa, Hiroshi Kurosaka, Takashi YamashiroAbstractThis is a case report of comprehensive treatment describing the management of an adult patient with bilateral cleft lip and palate who showed severe maxillary transverse deficiency caused by bilateral alveolar clefts. Since the residual alveolar clefts were extremely wide, we performed bone graft into the alveolar clefts first and then expanded the asymmetrically narrowed maxilla by asymmetric transverse distraction osteogenesis, in which an incision for osteotomy was...

Stability of anterior open bite in permanent dentition treated using extraction or non-extraction methods: A systematic review and meta-analysis of each method
ConclusionsOur findings indicated no significant relapse in extraction cases, but a significant relapse in non-extraction cases. However, due to no direct comparison, the optimum treatment method for open bite patients with permanent dentition remains questionable. Further studies with a high level of evidence that compare both treatment methods are needed to draw a definitive conclusion. (Source: Orthodontic Waves)

Hyoid bone position related to gender and aging using lateral cephalometric radiographs
ConclusionAge-related changes in hyoid bone position may decrease swallowing safety. Oral frailty, an early sign of orofacial muscle weakness and functional deterioration, negatively influences dental treatment and swallowing. The hyoid bone shifted to a posterior, rotated, and lower position with increasing age. Especially among males in the over 60-year age group, the hyoid bone had shifted significantly to a lower position. We should focus into the hyoid bone position in lateral cephalometric radiograph.

Buccal cortical bone thickness in different sagittal skeletal relationship
ConclusionsBuccal cortical bone thickness could be influenced by skeletal relationship. The mandible shows a similar pattern for all skeletal classes. In the maxilla each skeletal relationship shows a different pattern. Skeletal relationship need to be considered in site choice for miniscrew placement. (Source: Orthodontic Waves)

Treatment effects of mandibular anterior position training versus a fixed Class II corrector in growing patients with skeletal Class II malocclusion
ConclusionsBoth treatment modalities reduced severity of Class II malocclusion and decreased profile convexity. Class II elastics with anterior mandibular position training increased mandibular length more but required longer treatment duration. The PowerScope™ had a greater effect on maxillary dento-alveolar restriction. (ClinicalTrials.in.th: TCTR 20180220003). (Source: Orthodontic Waves)

Localization of leucine-rich repeat-containing G-protein-coupled receptor 5- and Ki67-positive periodontal cells expressing runt-related transcription factor 2 during tooth movement
ConclusionOur findings suggested that orthodontic force induced LGR-5- and Ki67-positive cells expressing RUNX2 in the PDL during tooth movement. (Source: Orthodontic Waves)

The use of temporary anchorage devices for orthodontic treatment of high-angle Class III malocclusion in a patient with impacted upper canine teeth
Publication date: Available online 25 July 2018Source: Orthodontic WavesAuthor(s): Yuka Murata, Ayaka Oka, Seiji Haraguchi, Takashi YamashiroAbstractThis case report describes the orthodontic treatment of a 13-year-old female patient with high-angle Class III malocclusion, including anterior open bite and impacted upper canine teeth with a convex soft tissue profile. In this case, preadjusted edgewise appliances were placed after the extraction of the upper deciduous canine teeth, impacted upper canine teeth and lower first premolars. The upper and lower dental arches were aligned using a temporary anchorage device (TAD) f...

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...

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)
