Evaluation of Hard and soft tissues around immediately placed implants with immediate loading versus immediately placed implants with delayed loading- A clinical and radiographic study Introduction: Teeth can be lost due to many reasons such as trauma, caries or periodontal disease. The classic and conventional protocols of implant placement usually have a waiting period of 6 months or more. In anterior aesthetic regions, it hampers patient satisfaction and confidence levels irrespective of the age or gender of the patient. To avoid this embarrassment, new protocol of immediate implant placement with immediate loading or immediate implant placement with delayed loading was developed.

Aim: The aim of the study was to evaluate the impact of immediately placed and immediately restored single tooth implant on hard and soft tissue and to compare it with immediately placed and delayed restored implants in the maxillary and mandibular anterior region.

Methods: The study was conducted on 30 patients, which were divided into 2 groups. Maxillary and mandibular anterior regions were included in the study. Based on coin toss method and insertion torque of the implants, they were divided into immediately placed with immediately loading and immediately placed with delayed loading. Soft and hard tissue parameters were measure as such, Soft tissue assessment: 1) Soft tissue thickness (measured at baseline, 1 month and 3 months) 2) Implant esthetic score (measured at 1 week, 1 month and 3 months) Hard tissue assessment–crestal bone level (measured at baseline and 3 months)

Results: Comparing Group A and Group B, there was no significant difference in the mean soft tissue thickness after 1 month and 3 months. For the implant esthetic score, there was no statistically significant difference seen between Group A and Group B. Considering Crestal bone levels, at baseline and 3 months, the levels were higher in the immediate loading cases as compared to the delayed loading cases.

Conclusion: There was no statistically significant difference in soft tissue thickness in both the groups, for the implant esthetic score, it was higher for the immediately loaded group compared to the delayed loading group. Crestal bone levels were higher for immediately loaded groups as compared to delayed loaded groups.
