Abstract

Wisdom tooth Management for Second molar extraction cases
Wisdom teeth, being the furthest back in both the upper and lower dentition, can easily remain unerupted, or partially unerupted if mandible development doesn’t leave enough eruption space for them. In orthodontic treatment, wisdom teeth can often nullify the results of treatment, and so are often extracted.
The first and second molars, due to problems during eruption period or hygiene, can present a caries risk, and at the beginning orthodontic treatment, may already have a large prosthetic, or have been subject to a root canal. With treatments in cases like this, when considering the stability of long-term prognosis, rather than focusing on preservation of the first and second molar, wisdom teeth can be effectively used in place of teeth with a long-term caries risk, which can be strategically removed during treatment. Our team combines tooth-movement specialist orthodontists, with extraction and other surgical procedure specialist orthognathic surgeons to accurately assess the difficulty of orthodontic treatment or extraction, eruption status, and anatomical conditions, such as the condition of the wisdom teeth, to effectively consider molar extraction in orthodontic treatments.
In this presentation, we share a case in which wisdow teeth are effectively utilized in post-molar extraction treatment for improved occlusal contact. Cases from several different categories of treatment types will be introduced and reported upon.

New Approach using 3D Printer for Aligner Orthodontics
The implementation of various intra oral scanning devices at our clinic has had great merit not only for us, but has also reduced treatment burden on patients as well. In orthodontic treatment, from diagnosis to analysis, record of treatment progression through to treatment finish and retention we create a portfolio of images of the entire jaw. Since the implementation of advanced scanners, the speed and precision with which these images are made has increased dramatically. With these scanners, the next step is making a full, tangible image of this data with 3D printers. This presentation will how the ways in which our clinical practice has changed since implementing digital printers, as well as how we use them during aligner treatment recovery.

Using TADs Approach with Invisailgn ~Biomechanics Oriented Orthodontics for TADs~
In recent years there have been many different cases and papers on the use of TADs in orthodontic treatments. TADs can be divided largely into 4 groups (1) plate type (2) mini screw (3) palatal plate type (4) zygoma type. Mini screw type TADs, which are minimally invasive and simple to install, have been frequently chosen for locations that minimize damage to roots and have a low failure rate. In our group, we believe that the most important element of orthodontic treatment, however, is careful consideration of planned tooth movement and biomechanics and appropriate TAD selection. Presently at our practice, when planning an aligner treatment, the orthodontist decides the direction of tooth movement and traction, and is then followed an oral surgeon who performs a data overlay with CT or STL data. Once possible installation locations have bern found, we choose a TAD type, create a surgical guide and perform installation. Doing this enables us to execute tooth movement more faithful to the plan resulting in highly predictable outcomes.
This presentation will discuss our approach to choosing TADs with careful consideration of the biomechanics of aligner treatments.
