Die Alignertherapie ist heute in aller Munde. 24 Jahre nach der Markteinführung von Invisalign durch Align Technology (San Jose, USA) hat sich auf dem Gebiet der transparenten Zahnkorrekturschienen einiges getan: Die Materialentwicklung ist vorangeschritten und es gibt zahlreiche klinische Studien zur Behandlung mit Alignern, sodass sich auch ehemalige Kritiker zunehmend der Aligner-Technologie öffnen.

The approach used to treat open bite depends on the origin of the anomaly and the Angle classification. This vertical deviation can be dental or skeletal in nature, or both combined. If removable appliances, such as an oral vestibular plate, or palatal expansion and myofunctional therapy are used in early treatments, multibracket therapy, extraction therapy or orthodontic treatment in combination with surgery are most used in the permanent dentition. Aligner therapy offers a valuable alternative approach for treating dentoalveolar open bite, and its use in combination with skeletal anchorage broadens the spectrum of orthodontics even more. The present article shows different examples of open bite patients treated with aligner orthodontics alone and discusses the incorporation of virtual articulators in treatment planning.

To overcome the limitations of the conventional vacuum thermo forming manufacturing process, the method of direct 3D printing of aligners has been developed. This presents more advantages than simply avoiding a two-step process, whereby the model needs to be printed first before the aligners are thermoformed. The shape memory function of-fers new and improved biomechanical options. This article presents the new direct 3D printed aligner material from Graphy (Seoul, South Korea) and a patient example demon-strating the course of treatment with the new material.

Artificial intelligence is now involved in many aspects of our everyday life. In digital orthodontic practice in particular, practitioners are constantly and mostly unknowingly confronted with different levels of implementations of artificial intelligence. The present article, the third in a three-part series, will seek to shed light on some of these algorithms using common examples from a standard orthodontic digital workflow. Schlagwörter: aligner orthodontics, artificial intelligence, digital orthodontics, machine learning

The present article describes the material properties of CA Pro (Scheu Dental, Iserlohn, Germany), a novel aligner foil, and demonstrates its performance in the orthodontic treatment of two cases with different characteristics.

Within the framework of treatment planning for missing teeth, the fundamental question is how to offer long-term solutions. One option is to close the space with a prosthetic restoration such as a dental implant or fixed or removable partial denture. Another option is orthodontic space closure, which makes it possible to avoid further tooth preparation, thus reducing the tooth substance required, or even generate new bone through the tooth movement into the gap due to the interdental fibres. Compared to space opening, however, space closure has far greater requirements in terms of anchorage. Preservation of the sagittal vertical overlap and adjustment of the dental midlines often necessitates use of skeletal anchorage, especially in cases of dental asymmetry. The present case report demonstrates a complex treatment using aligner orthodontics in combination with the Mesialslider (TADMAN, Gunningen, Germany) after loss of a maxillary molar, including a mandibular incisor extraction approach, closure of anterior open bite and solving of unilateral reverse articulation.

Artificial intelligence is now firmly established in society. Whether we are searching on Google (Mountain View, CA, USA), being guided by recommendation algorithms or using facial recognition or smart home software, artificial intelligence is a daily presence in our lives, and in almost all areas: business, science, medicine, and increasingly in orthodontics. What is artificial intelligence, what does it encompass, what can it already do in orthodontics and where is it taking us in the discipline? What opportunities does it offer and what negative effects does it have? In this article, the first in a three-part series, we will discuss these questions and strive to answer them.
