简要总结

Dental implants have become a widely accepted treatment modality for the replacement of missing single or multiple teeth in the recent years. In order to meet patients' needs for shorter treatment times and the necessity of dealing with more challenging clinical situations, implants and implant therapies have undergone continuous improvement to improve the function and longevity of the implants. Recently the constant search for improvements in modern implant have been focused on surface modifications so a new era of surface treatment have been showed up; the chemically modified hydrophilic surfaces.

结局指标

主要结局

Change in implant stability

时间窗: at baseline and 6 months

The implant stability measurement was examined at the time of insertion of the implants (primary stability) and 6 months (secondary stability) for the two groups of patients using the resonance Frequency Analysis (RFA) via the Osstell ISQ system

Biochemical assessment of bone formation

时间窗: at 3 months

Done by measuring of Runt-related transcription factor 2 (RUNX2) as a bone marker by Enzyme-Linked Immunosorbent Assay

Change in bone density

时间窗: at baseline and 6 months

Cone beam Computerized tomography was used to assess bone denisty

Change in ridge height

时间窗: at baseline and 6 months

Cone beam Computerized tomography was used to assess ridge height
