Q

Cauze anchiloze - reincluzie D

A

solutie de continuitate congenitala la nivelul membranei paro
- explica anchiloza la D neerupti - f rara
- contact prelungit cement-os - x fuziune, dificil de acceptat

P masticatorii mari sau trauma Oc - lezare locala membrana paro si ulterior osificare ca un proces reparator

Q

Consecinte reincluzie D

A
  1. denivelare plan Oc
  2. modificari de Oc - inclinare D vecini, migrari D antagonisti
  3. aparitie F anormale la nivelul D vecini - solicitati nefunctional
  4. incluzie succesional permanent - cel mai frecvent
  5. ectopie succesional permanent - rar
  6. carii de colet si/sau radiculare D vecini - zone retentive
  7. Hestezie, Hssb D vecini - zone denudate

Q

Modalitati tratament reincluzie dupa Bierderman

A

// cauza e anchiloza

  1. reconstituirea contactelor Px si Oc ale D in cauza
  2. luxare D anchilozat pentru distrugerea puntii osoase anchilotice
  3. extractie si replantare cat mai precoce
  4. expectativa

Q

In T reincluziei trebuie avut in vedere

A
  1. dintele in cauza - T/P
  2. gradul reincluziei - partiala/totala
  3. momentul aparitiei - precoce/tardiv
  4. ritmul evolutiei - lent/rapid
  5. consecintele asupra evolutiei celorlalti D - incluzii, ectopii, resorbtii
