Abstract
Purpose: To evaluate the correlation between bone density and implant stability using conventional and immediately extracted implant sockets.
Materials and Methods: 56 Straumann bone level implants were evaluated in this study. The patients were devided into 2 groups: Group A received immediate implant placement after extraction. Group B received conventional implant placement at edentulous area. Bone density of recipient site was evaluated using CBCT before implant placement. The insertion torque values (ITV) were measured at implant placement, and the resonance frequency analysis measurements (ISQ) were performed with Osstell instrument immediately after implant placement. In group A and group B, the correlation between bone density and implant stability parameters (ITV, ISQ) were evaluated.
Results: In Group A, the bone density was not correlated with ITV and ISQ (p>.05). However, Group B showed significant correlation between a) bone density and ITV and b) bone density and ISQ (p<.05).
Conclusion: Influence of bone density on implant stability was less effective at immediately extracted implant sockets compared to conventionally placed implant sites.
