Clinical Evaluation of Stability of Short Deep Threaded Dental Implant During Early Healing Period: A Prospective Controlled Clinical Trial

Objectives: To assess the initial stability of short, deep-threaded dental implants placed in the posterior mandible and to determine the influence of deep-thread design on implant stability during early healing. Methods: Twenty short, deep-threaded implants were placed in the posterior mandibular region of ten patients. Insertion torque value (ITV) was recorded at implant placement. Implant stability quotient (ISQ) was measured immediately post-surgery and at weeks 2, 3, 4, and 5. Results: No significant difference in ITV was observed between short and standard implants. ISQ values did not significantly differ between implant types across the evaluation period (F = 1.17, p = 0.3). Conclusion; Short, deep-threaded implants demonstrate comparable primary stability to standard implants in the posterior mandible. These findings support their use as a viable treatment option for patients with advanced alveolar ridge resorption
