“…This hesitancy often stems from the belief that such a treatment approach is inherently more intricate, demanding, and time-consuming. 8 Contrary to the trend reported by European and American scholars, Asai 18 and other researchers hold the viewpoint that Japanese patients, with severe crowding and convex profiles, may need the extraction of molars in addition to premolars.…”

“…23,24 When the crown is exposed, some clinicians suggest that bonding small and low-profile buccal tubes with 10° lingual crown torque designed for second molars could be necessary, which would provide enhanced control and help prevent lingual roll. 8,22 However, buccal tubes designed for the first molars were chosen, which was more conducive to the required mesial bodily molar movement. In addition, the third molars often exhibit irregular occlusal surface morphology, necessitating the reshaping of cusps during or after treatment to achieve an optimal functional occlusion.…”

“…Molar extraction is associated with many well-recognised challenges, including extended treatment times, anchorage management, and the control of the molars during space closure. 8 There is little difference between the first, second or third molars in relation to bite force. 9 In addition, while normal masticatory force constitutes only a third of maximum bite force, the periodontal ligament is able to withstand a considerably heavy load.…”

The first molar has been reported to be the most caries prone tooth in the permanent dentition. Rarely is the extraction of the four first molars the ideal choice in orthodontic treatment, especially the extraction of four molars and four premolars. However, the extraction program presents a treatment alternative in selected cases. In the following case report, the orthodontic treatment is described a 15-year-old male patient who presented with a dentoskeletal bimaxillary protrusion, and a chief complaint of”crooked teeth”. Moreover, the patient had a skeletal Class I malocclusion with crowded dentitions, a hyperdivergent growth pattern, deviated midlines and an extremely deep Curve of Spee. A satisfactory treatment outcome was obtained by the extraction of four premolars and four compromised first molars. The mechanics involved alignment, levelling, detailing the occlusion using a straight arch wire technique followed by retention. The active treatment time was 48 months. The treatment successfully achieved a bilateral Class I relationship of the canines and the right molars, a mild Class III relationship of the left molars, a normal overjet and overbite, aligned dental midlines, optimal intercuspation and a harmonious facial profile. The occlusion remained stable during 5 years of review.

ZusammenfassungDie kieferorthopädische Aufrichtung gekippter Molaren stellt eine häufige Behandlungsaufgabe dar. Dabei stehen neben funktionellen und präventiven Überlegungen vor allem parodontologische und prothetische Aspekte bei der Therapieplanung im Vordergrund. In der Literatur sind eine Vielzahl von Mechaniken und Methoden zur kieferorthopädischen Molarenaufrichtung beschrieben. Dabei erweitert der Einsatz von Mini-Implantaten heute das Spektrum der Verankerungsmöglichkeiten. Für die Auswahl einer geeigneten Mechanik sind die individuelle Ausgangsituation, das für die Therapieziele benötigte Kräftesystem und die Verankerung zu berücksichtigen. Im vorliegenden Artikel soll neben differentialtherapeutischen Überlegungen zu ausgewählten Mechaniken die Klinik der Molarenaufrichtung anhand von Fallbeispielen dargestellt werden.

Management of children with poor prognosis first permanent molars: an interdisciplinary approach is the key

et al. 2023

Although there have been continuous improvements in child oral health over recent decades, first permanent molars (FPMs) remain susceptible to early caries and can often be affected by hypomineralisation. We highlight current thinking in caries management and the restoration of hypomineralised FPMs, while also discussing enforced loss of these teeth within the context of interceptive extractions or extractions as part of orthodontic treatment. Compromised FPMs can negatively impact on quality of life for a child and present significant management challenges for the dental team. Although a high-quality evidence base is lacking for the different treatment options, early diagnosis and multidisciplinary treatment planning are key to achieving the best outcomes.
