 2020.10/31,11/1,2 International LH Orthodontic Course in Singapore 
 
3-day intensive / All English Course!! 
 
 
 
Course outline
Introduction to LH orthodontics
We use LH archwire for almost all cases. LH archwire was developed by Tokyo Medical and Dental University. LH is noted for its “One archwire method”, “Day-one torque control”, “Individual normal occlusion”, “shock and vibration absorbing property”, “LH Expansion Arch”, “LH Crossbite Arch” and dynamic anchorage by means of crimpable hook/stoppers.
Diagnosis and treatment planning
Introduction to quick diagnosis and complete treatment planning for high and low angle cases, extraction and non-extraction cases
Treatment goals are: ideal arch, desirable occlusion with adequate overbite and overjet, favorable cusp interdigitaion, and harmonious arch coordination
Anchorage preparation
(1) Intra-oral anchorage(IOA): We prepare anchorage with serial ligature tying(SLT) ,crimpable hook/ stopper, elastics, Curve, MEAW, and opposite direction.
(2) Reinforced IOA: a dual thread orthodontic implant with a revolving cap called “R1” is to be introduced, with its clinical applications.
(3) Extra-oral anchorage(EOA): J-hook when R1 is not applicable, and facemask for maxillary deficiency
Space preparation and creation
Space preparation: SLT+ open coil spring+ posterior MEAW
Space creation: Flare-out(LCC+open), Expansion(leveling), Distalization(stopper+open coil spring), Extraction, Stripping, MEAW
Incisor control
Right & Left: Midline correction & Incisor Angulation
Anterior(Flare-out) & Posterior(Lingual tipping) & Torquing
Intrusion & Extrusion: Not-in-slot, Elastic chain, Rebonding
+ Intrusion: (upper) J-hook, (lower) CAT=curve+active tie back, R1
+ Extrusion: up & down elastics
Dual-thread ortho implant with revolving cap (R1)
Development of dual-thread orthodontic implant with revolving cap (R1) will be introduced.
Features:
1. Self-drilling & immediate loading
2. Dual thread design
3. Soft tissue housing
4. Durable strength
5. Ideal stability
6. Dynamic anchorage
7. Secondary anchorage with a revolving cap as compensation for anatomic and inflammatory limitations
Leveling (1) De-rotation
Conventional treatment for severely rotated tooth requires multiple wire changing process. By LH leveling, one can perform correction of rotated tooth and torque control at the same time. Therefore, rotated teeth can be treated with LH leveling under a favorable torque control, from mere buccal side approach(no lingual button, lingual arch, etc).
Leveling (2) Molar management
Key to a successful molar management will be introduced, including
 
• Molar derotation…leveling(toe-in/out bend)
• Molar uprighting…open coil spring / leveling or MEAW/ implant
• Molar distalization…stopper + open coil spring
• Molar expansion…straight LH wire / archwire inside out
• Buccoversion and Scissors bite…lower bracket for upper/ bracket upside down(b-u-d)
• Molar control
   …intentional torque
   …tip back bend / toe-in & toe-out bend / LH MEAW
   Molar Intrusion…LH MEAW(6,7) / vertical offset(7)
   Molar Extrusion…IME(6)/ vertical offset(7)
• Molar impaction…surgical exposure + leveling (+open coil spring)
• Molar mesial drive
Treatment Strategy (1) Class II div.1 & div.2
Treatment strategy for Class II div.1 & div.2 will be introduced.
Also, consideration of Class II div.1: Type 1 & Type 2 will also be emphasized.
Treatment Strategy (2) Class III
Treatment of Class III cases is always a challenging scope of orthodontics in its difficulty and time consuming. The key element to achieve a successful therapy lies exactly in differentially diagnosing a Class III case as dental/functional or skeletal problem. We will discuss non-surgical treatment for Class III cases by LH Crossbite Arch, LH MEAW, and most of all, consideration and limitation for “Lower Extraction”.
Treatment Strategy (3) Open bite & Retention
We use LH MEAW technique to treat all kinds of open bite cases. Also, extraction consideration for open bite cases is taken into account. In addition, treatment for posterior open bite and reasons for transitional open bite are to be explained, too.
For open bite retention, we use circumferential retainer for the upper arch and Hawley retainer for the lower arch. An additional retainer with tongue crib and a reminder is advised for night wear only. For some cases suffering from facial asymmetry, with a view to maintaining jaw relationships, an FKO(one of Functional appliances) or a DP(dynamic positioner) for muscle training purposes (MFT) is also delivered.
Orthodontic treatment for Children (1) skeletal problem (2) shift and dental problems
