Abstract

Background:The aim of this study was to investigate
levels of bone morphogenetic protein-2 (BMP-2), BMP-7, soluble receptor
activator of nuclear factor-kB ligand (sRANKL) and osteoprotegerin (OPG) in the
peri-implant crevicular fluid (PICF) of implants placed in both maxilla and mandible
during the osseointegration period.

Methods:Thirty-three patients (17 females and 16
males; mean age 47.03±11.23 years) were included in this study. A total of 33
implants were placed in both of maxilla (Group 1/n=18) and mandible (group
2/n=15). Peri-implant
crevicular fluid (PICF) samples, modified plaque index (MPI), gingival index
(GI) and probing depth (PD) measurements were obtained at 1 and 3 months after
surgery. PICF levels of BMP-2/-7, sRANKL and OPG were analyzed by ELISA.

Results:No complications were observed during
the healing period. No significant differences were observed in the PICF
levels of sRANKL, OPG, BMP-2 and BMP-7 and evaluated clinical parameters between
groups at any time point (p>0.05). While PICF volume of group 2 was greater
than group 1 at first month, PICF volume of group 1 was greater than group 2 at
3 months (p<0.05). There was a positive correlation between sRANKL
levels and PICF volume (p<0.05) and a strong correlation between BMP-2 and
BMP-7 (p<0.01).

Conclusions:The results of this pilot study didn’t
show any significant difference in PICF levels of BMP-2, BMP-7, sRANKL, and OPG
in terms of anatomic location of dental implants. Further well-designed studies should be carried
out to evaluate the relationship between bone related biomarkers and anatomic
location of dental implants.

Abstract

Amaç: Bu çalışmanın amacı, hem maksilla hemde
mandibulaya yerleştirilen implantların periimplant oluğu sıvısında
osseointegrasyon süresi boyunca kemik morfogenetik protein-2 (BMP-2), BMP-7,
çözünür reseptör aktivatör nükleer faktör kappa B ligandı (sRANKL) ve osteoprotegrin (OPG) seviyelerinin
araştırılmasıdır.

Gereç ve Yöntemler:Bu çalışmada 33 hasta (17 bayan ve 16
erkek; ortalama yaş 47.03±11.23) yer almıştır. Hem maxillaya (Grup 1/n=18)
hemde mandibulaya (Grup 2/n=15) olmak üzere toplam 33 implant
yerleştirilmiştir. Peri-implant oluğu sıvısı (PIS) örnekleri, modifiye plak
indeksi (MPI), gingival indeks (GI) ve sondlama cep derinliği (SCD)
ölçümleri cerrahiden sonra 1. ve 3. ayda alındı. BMP-2/-7, sRANKL ve OPG PIS
seviyeleri ELIZA ile incelendi.

Bulgular:İyileşme süresince herhangi bir
komplikasyon gözlenmedi.Gruplar arasında sRANKL, OPG, BMP-2 ve BMP-7 PIS
seviyeleri ve incelenen klinik parametreler açısından herhangi bir zaman
periyodunda anlamlı fark gözlenmedi (p>0.05). PIS hacmi 1. ayda grup 2 de
grup 1’e göre fazla iken, 3. ayda PIS hacmi grup 1 de grup 2’ye göre fazlaydı
(p<0.05). PIS hacmi ile sRANKL arasında pozitif (p<0.05) ve BMP-2 ile
BMP-7 arasında güçlü pozitif korelasyon (p<0.01) mevcuttu.

Sonuçlar:Bu pilot çalışmanın sonuçları, dental
implantların anatomik lokasyonları açısından BMP-2, BMP-7, sRANKL, ve OPG PIS
seviyelerinde anlamlı bir fark gösterememiştir. Kemik ile ilişkili
biyobelirteçler ve dental implantların anatomic lokasyonu arasındaki ilişkinin
değerlendirilmesi için iyi dizayn edilmiş çalışmalar yapılmalıdır.
