Another route when Spee correction gets stuck
Beyond anterior intrusion, we will add options such as premolar extrusion, TAD-supported control, and alternatives for cases where classic methods alone do not solve the problem.
MASTERING THE CURVE OF SPEE
When the Curve of Spee does not level easily, what else can we do?
A clinical seminar from X UNIVERSITY on what to do when Spee correction stalls. We will organize classic approaches such as U-arch, slot selection, and stiffer wires, then focus on other powerful clinical options, including premolar extrusion, TAD-supported control, and aligner perspectives. The English edition is a translated archive, not live interpretation.
Putting words to why Spee sometimes levels smoothly, and sometimes does not.
For orthodontic specialists, GP dentists using aligners, GP dentists using fixed appliances, and younger orthodontists in university departments.
Curve of Spee correction can sometimes happen naturally through leveling, just like the textbook suggests. But in other cases, treatment progresses and the curve remains deep. Anterior intrusion does not seem to work. You are unsure how to manage the premolars. The occlusion does not settle cleanly at finishing.
When that happens, treatment becomes heavy if you only have one strategy. U-arch, slot selection, and leveling with stiffer wires are classic, well-known methods. In this seminar, we organize those foundations, then go beyond them: powerful clinical options for when Spee correction gets stuck, and aligner-side thinking for the same problem.
What You Take Home
Clinical viewpoints you can bring back to diagnosis, treatment planning, and sequencing.
A sequence that makes treatment lighter
We will organize classic methods such as U-arch, changing from .018 to .022 slot, and leveling with stiffer wires, then connect the next clinical decisions to the overall sequence.
Tips across labial, lingual, and aligners
We will share techniques that genuinely work in multi-bracket treatment, and also discuss aligner-side tips for Spee correction.
Speakers
Takao Minamidate will ask why and how strong clinicians make their decisions, and dig into the clinical reasoning.
Director, Yui Orthodontic Clinic
Shunsuke Takada
The “Haisai Curve”: an eye-opening method for Spee correction.
Joining from Okinawa, Dr. Takada is a bright, reliable senior-clinician type and a serious orthodontic specialist. He is also skilled in lingual treatment. In this session, he will mainly use labial multi-bracket cases to share how he efficiently integrates anterior intrusion and premolar extrusion into the treatment sequence.
Director, Kashiwanoha Campus Orthodontic Clinic
Shohei Komatsu
Efficient mechanics that start from the leveling stage.
From Kashiwanoha, Dr. Komatsu will explain labial multi-bracket clinical mechanics. He will organize the overview, problems, and difficulty of Spee correction in fixed appliance treatment, then unpack practical mechanics in a very clear way.
Director, Fukuoka MA Orthodontic Clinic / Moderator
Takao Minamidate
Founder of X University. Key points for Spee correction with aligners.
From Fukuoka, Dr. Minamidate will moderate as the host of X University. He will explain the key points of Spee correction with aligners and connect fixed-appliance tips with clinical decision-making.
Program
A lecture-based structure followed by discussion and Q&A to sharpen clinical decision-making.
LECTURE 01
Overview of Spee correction in multi-bracket orthodontics
Why is it difficult? Where does treatment tend to stall? We will organize the problems of leveling and occlusal design.
LECTURE 02
How to integrate anterior intrusion and premolar control into treatment
We will cover mandibular anterior intrusion with TADs, how to support the premolar region so it does not intrude, and how to use premolar extrusion clinically.
LECTURE 03
Classic methods, then the options beyond them
U-arch, changing from .018 to .022 slot, and leveling with stiffer wires are classic, well-known methods. This lecture starts from those foundations, then shares other powerful approaches and the clinical reasoning behind them.
APPLIANCE FREE
Tips that translate across labial, lingual, and aligner treatment
We will share techniques that genuinely work in clinical multi-bracket treatment. Takao Minamidate will also cover key points and tips for Spee correction with aligners.
DISCUSSION
Cases, decisions, and clinical tips in deeper discussion
The goal is to translate useful techniques passed down in clinical practice into clear, usable clinical language. Q&A included.
Who This Is For
If you have ever struggled with Spee correction, whether in wires or aligners, this archive should land clinically.
- Orthodontic specialists who want to organize fixed-appliance technique one level deeper.
- GP dentists who use aligners and struggle with deep bite or Spee correction.
- GP dentists who also provide wire/fixed appliance treatment and want more efficient leveling.
- Younger orthodontists in university departments who want clinical techniques beyond the textbook.
