The effect of implant characteristics on the implant stability of immediately loaded single implant cases: A prospective study

Introduction: Factors that affect primary and ultimate implant stability include characteristics of the type of dental implant used, bone quality at the site of implant placement, insertion torque, as well as micromotions at the bone–implant interface. This study, however, sought out to determine the effect and relationship between relevant implant characteristics and implant stability in immediately loaded single implant cases using the Periotest® M handheld device. Aim: To determine the effect of implant characteristics on the ultimate implant stability in immediately loaded single implant cases. Results: At placement, 33 (94%) of implants had periotest values between −0.8 and 0 at placement. There is a general decrease in the number of patients with periotest values −0.8–0 and those with +1–9 from the initial placement to 6 months after placement. It was further observed that there is a negative correlation between the implant length, diameter, and the mean periotest values although this was not statistically significant. Conclusion: There is a directly proportional relationship between implant characteristics and implant stability of immediately loaded implants.
