Abstract :

Introduction: The primary implant stability at implant placement is a mechanical phenomenon related to the quality and quantity of bone at the recipient site, the type and design of implant used and the surgical technique employed. Aims and objectives: To clinically evaluate and compare the primary stability of a commercially available implant system using Periotest and percussion methods. To evaluate and compare the primary stability achieved at baseline with the osseointegration at the second stage surgery (90 days) and at the time of prosthesis delivery (120 days). Materials and Methods: A total of twenty implants were placed in ten systemically healthy subjects, in the age range of 25–45 years, who presented with missing mandibular anterior teeth from lower right first premolar to lower left first premolar. Two stage rootform hydroxyapetite coated, pure titanium endosseous implants of diameter 3.3mm and implant length of 10mm & 13mm were placed. Subjects with sufficient alveolar bone volume at the implant site of > 5.5mm width labiolingually, 15mm height and type I and type II bone quality were divided into two groups depending on the length of implant placed: Group A (10mm) and Group B (13mm) . Complete blood investigation were done. Diagnostic intraoral and panoramic radiographs were taken and bone mapping was done. The Periotest values were recorded at baseline, after 90 days and 120 days. Results: The mean periotest values (PTv) of both the groups were statistically significant, indicating significant primary stability. On comparison between the two groups, the PTv in Group B were highly significant, indicating that primary stability of implant increases with increase in implant length. Conclusion: Primary stability of an implant is better in longer implants. The primary stability of implant is high on the day of placement, decreases by the second and third month and increases again after three months.
