Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In this clinical study, the samples were collected from patients with single teeth missing who came from the department of prosthodontics from the School of Stomatology of the Fourth Military Medical University.The prospective cohort study was used to investigate the correlation between different factors and the early stability of the implants. And then, using the correlation between different factors and the early implant stability gives predictable data about implant stability and then evaluate the accuracy and reliability.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Cone beam computed tomography (CBCT) was used for preoperative radiological evaluation of the jawbone for each patient, and then bone density in Houndsfield units scale was assessed by SimPlant Pro 11.04 software. Immediately after the implant placement and 12 weeks later, stability measurements were performed with Osstell™ Mentor.The captured data was represented in a quantitative unit called Implant Stability Quotient (ISQ) on a scale from 1 to 100 and averaged for each implant.
The descriptive statistical methods were used to show the differences in bone density and ISQ values among location, gender, age and implant diameter variables. Mann-whitney test was used for comparison of HU values and ISQ values between different age and gender groups. Kruskal-Wallis test was used for comparison of HU values and ISQ values between different location and implant diameter groups. The changes of ISQ values over time were compared using Wilcoxon signed rank test. The Spearman's rank correlation coefficient was used to investigate the correlation between ISQ values and HU values.
At last, to investigate the possible correlations between implant stability and bone density and to study the feasibility of predicting implant stability by using preoperative CBCT.
