Summary: This systematic review and meta-analysis aimed to analyze the accuracy of implant placement using computer-assisted dynamic navigation procedures. The results showed that the clinical accuracy of dynamic navigation is comparable to static navigation, but there is great heterogeneity in dynamic navigation systems, indicating a need for further research to validate their feasibility.

Summary: This study evaluated the accuracy of dental implant placement using a dynamic computer-assisted implant surgery (dCAIS) system and a freehand approach, and compared the patients' perception and quality of life with the two approaches. The results showed that the dCAIS system significantly improved implant placement accuracy compared to the freehand approach, but it also increased the surgical time and did not improve patient satisfaction or reduce postoperative pain.

Summary: The meta-analysis of ten studies showed that dynamic computer-assisted implant surgery achieves clinically acceptable accuracy. There were no significant differences found between different jaw types, guidance methods, and systems. However, more patient-centered outcomes and socio-economic benefits should be reported for further evaluation.

Summary: This in vitro study evaluated and compared the accuracy of zygomatic dental implant placement using a dynamic navigation system versus a conventional free-hand technique. The results showed that the free-hand technique enabled more accurate placement of zygomatic dental implants than the computer-assisted surgical technique. Additionally, placement in the anterior region was more accurate than in the posterior region.

Summary: This in vitro study aimed to investigate the influence of the process chain on the accuracy of a computer-assisted dynamic navigation procedure. Results showed that the position of reference markers can affect the precision of implant positions in the in vitro examination. Further clinical studies are needed to confirm these findings.

Summary: The study aimed to evaluate the accuracy of different approaches for zygomatic implant (ZI) placement in patients with severe maxillary problems. The results showed that dynamic computer-aided surgery (d-CAIS) and modified static computer-aided surgery (s-CAIS) had clinically acceptable outcomes, while the conventional s-CAIS had the highest deviation values. Surgeons should be aware of potential deviations and complications regardless of the selected approach.

Summary: Image-guided surgery, prosthetic-based virtual planning, 3D printing, and CAD/ CAM technology have revolutionized head and neck ablative and reconstructive surgical oncology, enabling accurate dental implant placement and improving quality of life. A learning curve exists for surgeons using guided methods, with dynamic navigation cases achieving the highest accuracy in implant placement. Smartphone-based augmented reality visualization is a valuable tool for intraoperative visualization and final verification, contributing to the success of free flap oncological reconstruction.

Summary: This study compared the accuracy of implant placement and patient satisfaction between dynamic computer-assisted implant surgeries (d-CAISs) using marker-based and marker-free registration methods. The results showed that the marker-free group had a significantly lower angular deviation compared to the marker-based group, while there was no significant difference in global linear deviations. There were no significant differences in the postoperative oral health impact profile scores between the two groups, but the marker-free group had significantly higher satisfaction with the treatment procedures.

Summary: In this research, a motion-tracking system for robotic computer-assisted implant surgery is investigated. Accurate implant positioning is crucial in order to avoid significant issues. The essential features of the motion-tracking system are analyzed and categorized into four categories: workspace, sampling rate, accuracy, and back-drivability. Based on this analysis, requirements for each category are derived to ensure the desired performance criteria. A novel 6-DOF motion-tracking system is proposed which demonstrates high accuracy and back-drivability, making it suitable for use in computer-assisted implant surgery. Experimental results confirm the effectiveness of the proposed system in achieving the essential features required for a motion-tracking system in robotic computer-assisted implant surgery.

Summary: The study aimed to investigate the impact of loading protocols on single dental implants in edentulous mandibles. Results showed that immediate loading led to lower survival rates compared to delayed loading, suggesting that immediate loading should be considered only in exceptional cases.

Summary: This clinical report describes the implant-supported prosthetic treatment of a 26-year-old patient with cleidocranial dysplasia who had not received orthodontic therapy in childhood. The treatment involved surgical pretreatment, placement of multiple implants using a three-dimensional template, and immediate loading of the implants. Clinical and radiological parameters suggest that concepts from implantology can be applied to patients with cleidocranial dysplasia.

Summary: This study analyzed the long-term success of treatments in shortened dental arch (SDA), finding that half of the patients could maintain the prosthetic status according to the treatment plan for over 10 years. However, the risk of losing the prosthetic status increased for moderate or worse failures. Overall, the influence of treatments on success rates appeared to be low.

Summary: After a 15-year follow-up, it was found that there was no significant difference in oral health-related quality of life between patients who received removable partial dentures for molar replacement and those who had a restored shortened dental arch without molar replacement. The study suggests that both treatment options are equivalent in maintaining long-term oral health-related quality of life, with no notable changes observed over the 15-year period.

Summary: This study found that healthy gingiva favored the effectiveness of the double cord technique for gingival displacement procedures, while mild gingivitis had a smaller impact on the kaolin paste technique. The gingival condition did not influence the changes in marginal gingival height, and the changes measured up to six months post-intervention were not considered clinically relevant.

Summary: This randomized clinical study compared the gingival displacement performance of 3M Astringent Retraction Paste with the double-cord technique. The results showed that both techniques had comparable performance in the horizontal direction and the cord technique was slightly better in the vertical direction. The marginal gingiva height changes were minimal during the 12-month follow-up period.
