Abstract
The aim of the present study is to compare two different implant surface chemistries of failing dental implants. Sixteen patients (mean age: 52 ± 8.27 with eight females and eight males) and 34 implants were included in the study. Group-I implants consisted of a blasted/etched surface with a final process surface, while Group-II implants consisted of the sandblasted acid etching (SLA) method. The chemical surface analysis was performed by the energy dispersive X-ray spectroscopy (EDX) method from coronal, middle, and apical parts of each implant. Titanium (Ti) element values were found to be 20.22 ± 15.7 at.% in Group I and 33.96 ± 13.62 at.% in Group-II in the middle of the dental implants. Aluminum (Al) element values were found to be 0.01 ± 0.002 in Group-I and 0.17 ± 0.28 at.% in Group II in the middle of the dental implants, and statistically significant differences were found between the groups for the Al and Ti elements in the middle of the dental implants (p < 0.05). There was a statistically significant difference for the Ti, Al, O, Ca, Fe, P, and Mg elements in the coronal, middle, and apical parts of the implants in the intragroup evaluation (p < 0.05). It is reported that different parts of the implants affected by peri-implant inflammation show different surface chemistries, from coronal to apical, but there is no difference in the implants with different surfaces.
Highlights
Accepted: 16 February 2021Peri-implantitis is an inflammatory disease characterized by alveolar bone loss and increased peri-implant pocket depth [1]
In a hypothesis presented by Mouhyi et al, it was reported that the formation of an acidic electrochemical environment due to excessive mechanical stress and bacterial biofilm causes the destruction of the oxide layer on the surface of the dental implant and that peri-implant fluids in direct contact with the Ti can be expected to affect this oxide layer [6]
A statistically significant difference was found in terms of the Ti and Al values in the evaluation of two different implant surface chemistries, but no significant difference was found in terms of other elements between the groups
Summary
Accepted: 16 February 2021Peri-implantitis is an inflammatory disease characterized by alveolar bone loss and increased peri-implant pocket depth [1]. In a hypothesis presented by Mouhyi et al, it was reported that the formation of an acidic electrochemical environment due to excessive mechanical stress and bacterial biofilm causes the destruction of the oxide layer on the surface of the dental implant and that peri-implant fluids in direct contact with the Ti can be expected to affect this oxide layer [6]. In another hypothesis proposed by Fretwurst, it was claimed that the Ti element released from dental implants could be expected to lead to host tissue
