Abstract

Amaç: Bu
çalışmada rat tibiyalarına yerleştirilen primer stabilite olan ve olmayan
titanyum implantların osseointegrasyonunun biyomekanik incelenmesi
amaçlanmıştır.

Gereç ve Yöntem: Bu
çalışmada kullanılan 42 adet, dişi Spraque Dawley rat 2 gruba ayrıldı. Primer
Stabili- te Olan (PS+) Grup (n=21); 2.5 mm çapında 6 mm uzunluğunda tornalanmış
yüzey titanyum implantlar deneklerin sağ ve sol tibiyalarına primer
stabilizasyon sağlanarak, Primer Stabilite Olmayan (PS-) Grup (n=21); 2.5 mm
çapında 6 mm uzunluğunda titanyum implantlar deneklerin sağ ve sol tibiyalarına
primer stabilizasyon sağlanmaksızın steril şartlarda cerrahi yöntemle
yerleştirildi. Denekler her bir grupta eşit rat olacak şekilde 4. (n=7), 8.
(n=7) ve 12. (n=7) hafta sonunda sakrifiye edildi. İmplantların
biyomekanik analizleri basma testine  tabi tutularak
gerçekleştirildi.

Bulgular:
Kuvvet değerleri PS+ grubunda PS- grubuna göre 4., 8. ve 12. haftaların sonunda
yüksek tespit edildi (P<0.05). PS+ grubunda 4., 8. ve 12. hafta kuvvet
değer- lerinde fark tespit edilmedi (P>0.05). PS- grubunda kuv- vet
değerleri 4. ve 8. haftalar arasında bir fark meydana getirmemişken
(P>0.05), 12. hafta kuvvet değerleri 4. ve 8. haftalara göre yüksek tespit
edidi (P<0.05). Yer değiş- tirme miktarları 4. haftada PS- grubunda PS+
grubundan yüksek tespit edilirken (P<0.05), 8. ve 12. hafta yer de- ğiştirme
değerlerinde gruplar arası bir fark tespit edilmedi (P>0.05).  PS+ grubunun 4., 8. ve 12.haftalarda yer
değiştirme miktarları arasında bir fark tespit edilmezken (P>0.05), PS-
grubunda 4. hafta yer değiştirme değeri 8. ve 12. haftalara göre yüksek tespit
edildi (P<0.05).

Sonuç: Primer
stabilizasyon olan implantlarda osseoin- tegrasyon primer stabilite olmayan
implantlara göre daha iyi düzeyde elde edildi. Primer stabilite olmadan da
osseointegrasyon sağlanabilir.

BIOMECHANIC EVALUATION
OF THE BONE IMPLANT CONNECTION OF THE PRIMARY AND NON-PRIMARY STABILIZED TITANIUM
IMPLANTS: AN IN VIVO STUDY

ABSTRACT

 

Aim: In
this study it was aimed to that biomechanic evaluation of the primary
stabilized and non-primary stabilized titanium implant osseointegration in rat
tibias.

Materials and Methods: In
this study, 42 female Spraque Dawley rat were used and diveded 2 groups: Primer
stabilized group (PS+) (n=21); 2.5 diameter and 6 mm long titanium implant was
integrated in rat tibias both left and right side with primary stabilization. Non
primary stabilized (PS-) (n=21) group; 2.5 diameter and 6 mm long titanium
implant was integrated in rat tibias both left and right side without primary
stabilization. Surgical procedure was done under steril condition. Rats were
sacrified in 4. (n=7), 8. (n=7) and 12. (n=7) weeks in equal number in each
group. Biomechanical analysis of the implants were done with
compression test

Results: Force
magnitudes detected higly compared in PS+ compared PS- in 4., 8 and 12. weeks
(P<0.05). In PS+ any difference was not detected in forces at 4., 8. and 12.
weeks (P>0.05). In PS- group; difference was detected in forces at 12. week
when compared 4. and 8. weeks (P<0.05). Displacement in PS- group detected
highly compared with PS+ in 4. week (P<0.05), but in 8. and 12. weeks any
difference was not detected between two groups (P>0.05). any difference was
not detected at 4., 8. and 12. weeks in displacement values in PS+ group
(P>0.05). But in PS- group displacement values was detected highly in 4.
week compared 8. and 12. Weeks (P>0.05).

Conclusion:
Osseointegration in primary stabilized implants was detected better than
non-primary stabilized implants. Osseointagration could enhance without primary
stabilization.
