Abstract:
This study was aimed to objectively measure the changes in bone density amount obtained through cone-beam computed tomography around dental implants after a short period of time in the maxilla. Thirty-two SLActive Straumann implants were inserted into 12 healthy patients. Changes in bone density were measured at the surgery time (Bone mineral density (BMD)0) and 60 days after investment (Bone mineral density (BMD)60). Statistically, significant differences were observed between traumatic and sinus zones at the time of surgery and after 60 days respectively (P ≤ 0.05). For each group, a significant decrease in density was observed with the following variables (male, age of 18-40 years, sinus zone, and implant diameter of 4.1 mm). The survival rate was 83.8% after 60 days. Implant surface modification has no significant effect on bone mineral density after a short period of time in the sinus zone. Early loading of the prosthesis can be performed in the traumatic zone only.
