Chapter
An increasing number of patients seek orthodontic treatment with aligner therapy. Pure bodily tooth movement with sequential plastic aligner therapy is challenging to achieve to a high degree of predictability. As a consequence, unilateral or bilateral molar distalization is limited when relying on aligner movement alone. By using palatal mini-impl...
Article
Introduction: Orthodontic mini-implants are frequently used to provide additional anchorage for orthodontic appliances. The anterior palate is frequently used owing to sufficient bone quality and low risk of iatrogenic trauma to adjacent anatomical structures. Even though the success rates in this site are high, failure of an implant will result i...

The aims of this study were (i) to develop a simulation unit to mimic point set registrations and (ii) to evaluate the impact and clinical relevance of manual landmark sele...
Article
In cases with missing maxillary lateral incisors, the two major treatment approaches are space closure and space opening. In many cases, space closure to the mesial seems to be the favourable treatment goal, since treatment already can be completed as soon as the dentition is complete. However, the demands for anchorage are quite high. Both reverse...
Article
Full-text available
Mini-implants were introduced in recent years as a new method of anchorage reinforcement. In addition to classical treatment tasks like distalization to gain space and mesialization for space closure, mini-implants can also be used for pre-prosthodontic treatment objectives such as extrusion of roots or impacted teeth, uprighting of tipped teeth, o...

Full-text available
Recently, skeletal anchorage devices have been used as anchorage units for upper molar intrusion as a way of correcting an anterior open bite malocclusion. To avoid the surgical procedures associated with the placement of miniplates in the zygomatic area, mini-implants may be inserted palatally or buccally in the alveolar process. However, consider...
Article
Full-text available
Currently, the alveolar process is the most preferred insertion site for orthodontic mini-implants. However, due to the varying bone quality and the risk of root contact, the survival rate of implants inserted in the alveolar ridge still needs improvement. Other regions, such as the anterior palate and the mental region provide much better conditio...

A treatment objective of upper molar distalisation may often be required during the correction of a malocclusion. Distalisation is not only indicated for the management of Class II patients, but also for Class III surgery patients who require decompensation in the upper arch if upper incisor retrusion is needed. Unfortunately, most conventional int...
Article
Full-text available
Growing class III patients with maxillary deficiency may be treated with a maxillary protraction facemask. Because the force generated by this appliance is applied to the teeth, the inevitable mesial migration of the dentition can result in anterior crowding, incisor proclination and a possible need for subsequent extraction therapy. The Hybrid Hyr...
