Dental Biomekanik movement Ortodontik

Principles of tooth movement
Terms of teeth can be moved:
1. There should be a place where the teeth will be moved
2. There should be a strength with the optimal direction in the right gear
3. Network periodonsium teeth must be well
This requirement must be observed so that the teeth in the jaw-teeth can be treated with care at both the ortodonsia. Because not a few cases of severe maloklusi increased after treatment with ortodonsi tools.

The concept of movement of teeth
Given the strength of the dental crown will cause the teeth will be slightly changed the location of the tooth socket. The strength of a given area that can cause pulling and pressure on the teeth. At a certain period, the socket will change gear teeth and will move away from the tooth socket

Gigi Ortodontik movement depends on:
A. Ortodontik strengths include:
1. Type of power
2. The direction and amount of power
3. Duration strength
B. Various movements Gigi
1. Tipping movement
2. Bodily movement
3. Rotation movement
4. Movement intrusion
5. Movement ekstrusi
6. Torque movement

The strength will be given planned correctly. Strength that is not correct can cause reactions that are not desired.
Planning must consider the strength of teeth penjangkar and network conditions periodonsium

Type of power
1. Strength continuously. Strength continuously. The strength of the continuous will stop at a certain period. Eg using the expansion jaw coffin, wire bow on uređaja ortodonsi cekat
2. intermittent power. Strength is in progress during a short period. Strength of the tools are usually intermittent ortodonsia lepasan. For example: expansion of the screw

The direction and amount of strength and duration of power
Tipping movement with roots and a single minimum hialinisasi: 25-40 grams with the movement of at least 1 mm / month
Have a threshold value
- Power above the threshold value
- The strength of the threshold value continuously hrs
Small enough strength hrs spy out tjd hialinisasi in ligamen periodontal
- Bodili: distribution pressure evenly, allows not going hialinisasi
- Tipping: hialinisasi tjd in alveolar Crest (Tech max), 2-3 after normal sunday
- Major strengths: hialinisasi large area, moves into gear teeth shake, hialinisasi continues, tertundanya
movement of teeth, loss of penjangkaran
Strength is provided for:
- Tipping movement: 50-75 gm
- Bodily movement: 100-150 gm
- Movement of rotation: 50-75 gm
- Movement ekstrusi: 50-75 gm
- Movement intrusion: 15-25 gm
- Duration is the length of the strength of treatment ortodonsia itself

Tipping movement
- The movement of teeth inclined toward the mesial, distal, bukal, or lingual.
- Generated by the movement of teeth through one point contact between the spring with the teeth.
- Given the strength of the work at one point on the crown gear teeth so that it will move italics /
tipping with a rotation on fulkrum
- Movement on this apeks will move towards the opposite direction of movement
crown
- Usually fulkrum point location is 1 / 3 the length of the root apeks (30-40%)
- So that the movements that can be corrected this aberration is the version set teeth, the movement can not
expected too much

Torque movement
- The tipping movement of teeth in the apeks

Bodily movement
- Gigi moved comprehensively (bodily)
- Need extra power to control the position fulkrum

Movement intrusion
- Movement is a movement intrusion avoid dental field oklusal
- Movement control strength intrusion requires a good
- The permanent teeth that have not grown perfect, too given the strength to be oklusal
cause movement intrusion
- Examples are elevation anterior bite on the bite in case. Insisif RB oklusi the rise dg
nibble page (inexact vertical) move tiping and intrusion. Posterior tooth-tooth contact is not to be. Purpose
elevation anterior bite is the bite with overlapping stimulate growth gigi2 posterior
dg prosesus alveolarisnya to oklusal


Movement ekstrusi
- The movement towards a tooth-tooth oklusal
- This movement is used in cases of open bite.
- Used labial bow is placed more to encourage that cervical tooth-teeth to oklusal

Rotation movement
- Correction tooth rotation (derotasi)
- Using more than one kind of strength. For example, for dental insisif RB rotation used 2 power
labial bow that is on the labial side and the spring on the Z palatal
- Tools lepasan used when little rotation
- Rotation with many cekat tool or combination of tools & equipment cekat separated
