Öğe Comparison of Osteoimmunological and Microbiological Parameters of Extra Short and Longer Implants Loaded in the Posterior Mandible: A Split Mouth Randomized Clinical Study(Univ Zagreb, Sch Dental Medicine, 2021) Karci, Bilge; Oncu, ElifObjectives: This study aimed to evaluate the levels of TNF-alpha, PGE., RANKL, RANK, OPG, the markers of periimplant bone toss in peri-implant crevicutar fluid obtained around standard and extra short implants. Moreover, the levels of putative oral pathogens were investigated in the submucosal biofilm samples. Material and Methods: The implants were divided into two groups according to their Lengths: standard (>= 8 mm) and extra short (4 mm). A total of 60 implants were researched in 30 patients. The probing depth (PD), clinical attachment level (CAL), presence of bleeding on probing (BOP), 3-year survival rate (CSR), and bone toss (BL) were measured. Results: No statistically significant difference was found in the values of PD, CAL, BOP, CSR, and BL between the groups (P> 0.05). Total amounts of PGE,, RANKL, RANK, OPG, and RANKL/OPG were not statistically significantly different between the groups (P> 0.05). The abundance of F. nucleatum, T. forsythia, P. intermedia, P. gingivalis, S. oralis and T. denticola was compared between the groups and the results were not statistically significant (P> 0.05). Conclusion: The results of this study suggested that PGE(2), TNF-alpha, RANKL, RANK, OPG, and RANKL/OPG in PICF, as well as microbiological parameters in submucosal biofilms, were similar between standard (>= 8 mm) and extra short (4 mm) implants. Therefore, the implant length does not seem to influence the bone loss, levels of osteoimmunological and microbiological markers in the peri-implant tissues and survival rates.Öğe Comparison of Osteoimmunological and Microbiological Parameters of Extra Short and Longer Implants Loaded in the Posterior Mandible: A Split Mouth Randomized Clinical Study(Univ Zagreb, Sch Dental Medicine, 2021) Karci, Bilge; Oncu, ElifObjectives: This study aimed to evaluate the levels of TNF-alpha, PGE., RANKL, RANK, OPG, the markers of periimplant bone toss in peri-implant crevicutar fluid obtained around standard and extra short implants.

A total of 71 implants from 37 patients were assessed, grouped according to the surface characteristics of the implants: SLA surface (Group 1), fluorine-modified surface (Group 2), and anodized surface (Group 3). The following clinical indices were measured: Gingival Index (GI), probing depth (PD), bleeding on probing (BOP), clinical attachment level (CAL), and keratinized tissue width (KTW). Peri-implant sulcus fluid and subgingival plaque samples were also collected. Commercial enzyme-linked immunosorbent assay (ELISA) kits were purchased for measuring TNF-alpha, PGE2, RANKL, RANK, and OPG. Real-time quantitative polymerase chain reaction (PCR) was used to detect P intermedia, T forsythia, T denticola, F nucleatum, P gingivalis, and S oralis levels in the subgingival biofilms. The groups showed no statistically significant differences in GI, PD, BOP, CAL, KTW, or peri-implant status. The total amounts of PGE2, TNF-alpha, RANKL, RANK, and OPG and the RANKL/OPG ratio were not significantly different between groups. F nucleatum, T forsythia, P intermedia, P gingivalis, and T denticola were significantly higher in Group 3 implants. DNA concentrations of S oralis were higher in Group 2. Within the limitations of this study, SLA and fluorine-modified implant surfaces may be more clinically successful than anodized-surface implants.
