Preventive Orthodontics
Definition of Preventive Orthodontics
It is the actions taken to preserve the integrity of the arches, alignment
&harmony of dentition to maintain normal occlusion.
Things to do:
1- Preservation to primary teeth in their position because they are the guide to permanent eruption
2- Determine the relation between dentition, skeletal, and muscular to reach the good harmony to
avoid loss of space
3- Stop any habit affects the environment around teeth because it affects the teeth
Practice of preventive ortho
1- Knowledge and skill of the dentist
2- Patient motivation (to maintain oral hygiene and tooth structure)
3- Parents instructions
Knowledge like:
- Spacing → Important for providing the mesiodistal width between permanent and primary teeth,
so it will make good alignment of dentition in
the arch
- Double raw → Lower anterior teeth erupted
lingually, the tongue pushes them forward
(primary teeth out of occlusion must be Mesiodense teeth Spacing Double raw
extracted)
- Mesiodense teeth → Must be removed because it affects the arch length
Skill like:
- Return the proximal contact area to normal after class II
- Permanent teeth have contact point and primary teeth
have wide area, so if we leave caries or open contact,
Mesial shift will occur, so we will need more space to
accommodate the permanent teeth
So we should make perfect restoration
- If a patient comes with space between primary teeth, harry to put space maintainer until the
eruption of the permanent teeth
, - Able to eliminates habits like thumb sucking, pacifier habit and mouth breathing
✓ Thumb sucking
✓ Mouth breathing → high palate
✓ pacifier habit → The pacifier should be chosen anatomically, if not it will do
the same problems of thumb sucking
- The Rose one is better than the green cause its shape like the
palate and it is very thin
- Withdrawal with pacifier is much easier than thumb sucking
Parents instructions (Child under control from parents)
They must know Tooth brushing, Pit & fissure sealing → Caries ↓
Premature Loss
Causes:
- Dental caries (should be controlled by fluoride & pit and fissure sealing or make cavity then put
restoration specially with GIC)
- Dental trauma in primary dentition can alter the alignment of teeth & space loss.
- Ankylosis of primary teeth (Ruin the pathway of eruption of permanent teeth)
- Hypophosphatasia (affects bone → soft, Root → resorbed) make the environment not well
mineralized, results no support from the bone
- Leukemia (observed from inflammation & ulceration)
✓ makes abscess in the sound teeth
✓ Abnormal leukocytes in blood enters nerves → stagnation → thrombosis → death of tooth
due to cut of blood supply
