Background To evaluate the accuracy of implant placement assisted by a dynamic navigation system, as well as its influencing factors and learning curve. Methods At Macao We Care Dental Center, 55 cases of implant placement using dynamic navigation were retrospectively evaluated. To evaluate their accuracy, the apex, tip, and angle deviations of preoperatively planned and postoperatively placed implants were measured. The effects of the upper and lower jaws, different sites or lateral locations of dental implants, and the length and diameter of the implants on accuracy were analyzed, as well as the variation in accuracy with the increase in the number of surgical procedures performed by dentists. Results The implant had an apex deviation of 1.60 ± 0.94 mm, a tip deviation of 1.83 ± 1.03 mm, and an angle deviation of 3.80 ± 2.09 mm. Statistical differences were observed in the tip deviation of implants at different positions based on three factors: jaw position, lateral location, and tooth position (P < 0.05). The tip deviation of the anterior teeth area was significantly greater than those of the premolar and molar areas. There were no statistically significant differences in apex deviation, tip deviation, or angle deviation between the implants of different diameters and lengths (P > 0.05). There were significant differences in the angle deviation between the final 27 implants and the first 28 implants. Learning curve analysis revealed that angle deviation was negatively correlated with the number of surgical procedures, whereas the regression of apex deviation and tip deviation did not differ statistically. Conclusions The accuracy of dynamic navigation-assisted dental implants meets the clinical needs and is higher than that of traditional implants. Different jaw positions, lateral locations, and implant diameters and lengths had no effect on the accuracy of the dental implants guided by the dynamic navigation system. The anterior teeth area had a larger tip deviation than the posterior teeth area did. As the number of dynamic implantation procedures performed by the same implant doctor increased, the angle deviation gradually decreased.

Background Oral rehabilitation with dental implants is a common procedure in modern dentistry due to its high success rates. However, complications such as implant displacement can occur, particularly in the maxillary region due to factors like atrophied maxilla, thin alveolar bone, and low bone density. This case series explores scenarios of maxillary dental implant displacement, emphasizing the impact of immediate preoperative imaging on patient outcomes. Case presentation Three cases of maxillary implant displacement are presented, each illustrating a different scenario. Complications resulting from the displacement of implants into adjacent structures such as the maxillary sinus and nasal cavity are described. All cases involved implants that were displaced during second-stage surgery, occurring four to six months post-implantation. Removal attempts used transnasal endoscopic, intraoral, or combined approaches, with only one implant successfully retrieved. Delays in surgery ranged up to 72 h, leading to one implant being swallowed and another unlocated. Outcomes varied, with some patients requiring hospitalization for up to five days. Conclusion This series highlights the crucial role of immediate preoperative 3D imaging in precisely locating displaced implants to ensure their safe and efficient removal. While implant displacement may not always be preventable, optimizing the timeframe between diagnostic imaging and surgical intervention can significantly enhance management. Accurately locating the implant minimizes treatment invasiveness and patient discomfort, thereby improving clinical outcomes.
