Q

reactia de priza compomeri

A
  • primar- fotopolim
  • pe masura ce abs apa- reactie acid-baza lanturi carboxil- sticka
23
Q

diferente intre COMP si CIMR

A

comp- fotopolim+ r acid baza tardiv
cimr- fotopolim+ r acid baza debut imediat

24
Q

produse comerciale compomeri

A

F2000 compomer/ 3M
Dyract
Dyract AP
Dyract eXTRa
Hytac Aplitip/ Espe
Compoglass/ Ivoclar

25
compozitie compomeri
1. matrice org dimetacrilica+ grupari acide carboxilice 2. umplutura- sticla fluoro alumini silicatica
26
compozitie chimica compomeri
faza org faza anorg ag cuplare
27
faza organica compomeri
monomer baza: CDMA, UDMA monomer dilutie: GDMA, TEGDMA polimer hidroxilic HEMA sistem foto- amine tertiare CPO2
28
actiune polimer hidroxilic HEMA in compomeri
modifica reologia transport apa+ fluor
29
faza anorg in compomeri
sticla fluoroaluminosilicat 45-67% fluorosilicat de strontiu( Dyract)
30
agenti cuplare compomeri
silicat coloidal - dispersie larticule anorg -leaga cele 2 comp
31
componenta lichida compomeri denumiri si rol
PRIMER- NRC, Prompt L Pop faciliteaza adeziune necesita/ nu necesita demineraliz contraindicata pt alte materiale
32
indicatii compomeri
eroziuni cervicale- lacune cuneiforme carii radiculare obt cls 3,4 pt obt cls 1,2- restaurare mixta compomer+ RDC restaurari bonturi- coroana mai prezinta 1/2 pereti restaurari coronare dinti fracturati clasa 1,2 dinti temporari sigilare lineri/ baze
33
contraindicatii compomeri
nu se fol pt coroane total ceramice
34
prop mecanice compomeri
- rez mecanica> CIS si CIMR, asem RDC cu microumplutura - duritate <= RDC - rez la abrazie scade in timp dat atac acid particule sticla si derulare reactie acid baza
35
prop de suprafata compomeri
m bune decat CIMR si pastrate in timp
36
prop adezive compomeri
14-20 MPa - ca RDC- utilizare sist adezive similare
37
efect carioprofilactic compomeri
- atacul acid asupra particule de sticla fluoroaluminosilicatica=> eliberare ioni F - timp redus fara carie secundara
38
contractia de polimerizare compomeri
~ RDC - maj cintractiei in faza plastica, poate fi compensata prin fluaj - efect benefic reducere stres rezidual si inchidere marginala
39
absorbtie apa compomeri
>RDC - datorita HEMA fav eliberare F prin matrice org hidrofila in cant mare=> efect negativ asupra prop mecanice
40
vascozitate compomeri
< RDC deci aplicare mai usoara
41
dilatare termica compomeri
= struct dent aprox 11 ppm/ grade celsius
42
eliberare fluor compomeri
cant mici fata de CIS si CIMR
43
cat se fotopolimerzi compomerii
40 sec
44
cu ce se face prelucrarea obturatiei compomeri
cu discuri si benzi lustruit
45
ce se intampla daca exista compomer nepolimerizat
efect iritativ local
46
denumire comerciala rasini compozite silorani
Filtek Silorane 3M Espe
47
ce sunt rasici compozite pe baza silorani
mat compozit microhibrid in compozitie silorani ( siloxani+ oxirani)
48
contractie polimerizare rasini baza silorani
0,9%
49
dezavantaje rasini silorani
estetica de adeziune
50
sistem clasificare dinti endo- restaurati
clasa 0- reconstituire bont coronar din compozit clasa 1- aplicare pivot clasa 2- interventii pre restaurative (extruzie ortodontica, alungire coronara) clasa 3- pivot aur clasa 4- extractie
51
cand se aplica pivot
dinti frontali+ PM cu <50% din structura dura restanta raport coroana- radacina nefavorabil
52
rol pivot aur
conservare dinte in absenta ferrule effect creste modul elasticitate- suporta m bine stres creste risc fractura radiculara
53
dimensiuni minime ferrule effect
inaltime 1,5-2 mm grosime > 1 mm
