This study aimed to evaluate the impact of multimedia and verbal information on patients' knowledge, anxiety, and decision-making regarding dental implant surgery, focusing on comparing computer-assisted and freehand techniques. This randomized controlled trial involved 100 patients divided into two groups: one receiving multimedia information (n=50) and the other receiving verbal information (n=50). Data were collected through self-administered questionnaires assessing patients' baseline information, knowledge, anxiety, and decision-making before and after receiving information about dental implant surgery techniques. Results showed significant increases in knowledge scores for both groups, with the multimedia group improving from 1.96 to 3.90 (p<0.001) and the verbal group from 2.0 to 3.98 (p<0.001). Anxiety levels decreased significantly in both groups, with reductions from 12.76 to 11.48 (p=0.001) in the multimedia group and from 13.92 to 12.16 (p<0.001) in the verbal group. The proportion of patients who decided to proceed with dental implant surgery increased from 70% to 78% in the multimedia group and from 54% to 66% in the verbal group. After receiving the information, more patients in both groups opted for computer-assisted implant surgery, though treatment costs remained a significant concern for some, leading to declines in surgery acceptance. Despite these findings, no significant differences were observed between the multimedia and verbal groups regarding knowledge improvements, anxiety reduction, or decision-making. In conclusion, multimedia and verbal information effectively enhanced patient knowledge and reduced anxiety about dental implant surgery, and both methods may influence patients' decisions regarding their preferred implant technique, with no significant differences between the two methods.

Objectives: To compare the accuracy of position and parallelity of two implants, using static and dynamic CAIS systems. Materials & Methods: 30 patients received two implants randomly allocated to 2 different CAIS systems. Optimal implant position and absolute parallelity was planned based on preoperative CBCT. Implants were placed using surgical guide (static CAIS, n = 15) and real time navigation (dynamic CAIS, n = 15). Implant 3-dimentional deviation and parallelity was calculated after surgery. Results: The mean deviation at implant platform, apex and angulation in the static and dynamic CAIS group was 1.04 ± 0.67 mm, 1.54 ± 0.79 mm, …
