Introduction: Dental implants have had a phenomenal rise in recent years. Design of the implant, biology of the bone, primary stability, osseointegration, prosthesis are the major factors taken into consideration for successful implant therapy. Primary stability is the initial engagement between bone and implant and one has to ensure that it should be strong enough. Implantologists completely monitor primary stability by synchronizing the above factors. Aim: To study the association between primary stability and crestal bone loss in implants placed in edentulous maxilla and mandible. Materials and methods: This is a retrospective study conducted in Saveetha Dental College and Hospitals, Chennai, India. The data of patients: age, gender, primary stability and crestal bone loss who had undergone implant placement from September 2019 to March 2021, was collected from the case sheets. The study had a sample size of 112 subjects. The data was tabulated in Excel and imported to SPSS for statistical analysis. Results and discussion: Most of the patients had no crestal bone loss, but a significant number of them had crestal bone loss of 1 mm and above. 2.68% of males and 0.89% of females had crestal bone loss of 4 mm and above. Primary stability of 30-40 Ncm was most prevalent among all age groups and gender. The association between primary stability and crestal bone loss was not significant. Conclusions: No significant association was evidenced between primary stability and crestal bone loss in implanted patients. Proper selection of bone graft materials and implant design are the key components of managing crestal bone loss.
