Abstract

Introduction: Although several studies demonstrate predictable outcomes of non-submerged implant placement with concomitant contour augmentation, to our knowledge, there are no studies comparing these two techniques directly. Aim: The primary and secondary objectives of the present study were to compare vertical and horizontal facial bone dimensional changes around implants subjected to contour augmentation at the time of implant placement in a submerged and non-submerged treatment approach after 4 months of healing. Methods: A total of 16 patients in need of single tooth replacement were recruited and distributed into submerged and non-submerged groups using block randomization (n = 9 for control group, n = 7 for test group). Astra EV implants were placed with simultaneous guided bone regeneration using mineralized cortical bone allograft particles and a non-cross-linked collagen membrane. Clinical and radiographic measurements were performed at baseline and at 4 months. At baseline, the following parameters were measured intraoperatively: vertical defect height (VDH), horizontal defect depth (HDD), horizontal defect width (HDW), intra-bony component of the defect (INTRA), and soft tissue thickness (STT). In addition, a cone beam computed tomography (CBCT) was taken immediately after completion of the surgery to show the volume of the augmented area. At 4 months, a CBCT was taken to evaluate healing and remodeling of bone at different levels of the defect. Results: At the 4-month follow-up, all 16 implants integrated successfully within bone, and uneventful healing was noted. The results demonstrated statistically significant bone remodeling within the groups. However, there were no statistically significant differences between the submerged and non-submerged implants in regard to bone regeneration and soft tissue healing. Conclusion: A non-submerged approach is a predictable method for implant healing with simultaneous contour augmentation. The study failed to find significant differences in bone and soft tissue responses between the groups.
