Displacement is common Tooth fracture is common
Intrusion Extrusion Displacement
Maturation of root: crown fracture or root fracture Immaturation of root: Mobility,displacement ,extrusion
2.2.4 therapy method
coronal third
endodontic-orthodontic combined treatment
tooth fracture
middle third
• replacement and splinting • fixed for 2-3mouths • review :broken ends healing and pulp vitality • root canal therapy when broken ends healing

tooth tissue Integrity display to be enamel fissure no sclerous tissues defect no tooth luxation.
tooth fracture
2.1.3 crown fracture with pulp exposed
they were sensitive to the caloric stimulation pulp could be infected and hyperblastosis if it didn't treat in time
tooth fracture
Treatment
No disposal Grinding and polishing to restore in short-term for the small areas to restore after viewing for the large areas
tooth fracture
tooth fracture
2.2.1 It can be divided into three types

tooth fracture
2.1 crown fracture
• it was the commonest in the tooth fracture • it was predilected in incisal angle and edge • It can be divided into three types :
concussion
2.3 dental tissue injury
• enamel fissure
concussion
3. Treatment
eliminate occlusal trauma diminish or avoid irritation prevent infection deal with enamel surface fissure follow-up periodic review
merely enamel fracture enamel fracture with dentin exposed crown fracture with pulp exposed
tooth fracture
2.1.1 merely enamel fracture
it was predilected in incisal angle and edge, dentin didn't expose
tooth fracture
second paragraph:tooth fracture
1. definition: fracture took place in tooth hard tissues ，such as enamel, dentin and cementum.
2. clinical types: 2.1 crown fracture 2.2 root fracture 2.3 crown-root fracture
tooth fracture
Treatment direct pulp capping (it was difficult to success) palpotomy(root immaturating) apexification(root immaturating) root canal therapy(root maturating)
