Summary: This study aimed to assess the accuracy of virtual planning of computer-guided surgery based on the actual outcomes of clinical dental implant placement. The results showed that computer-guided surgery with the flapless approach demonstrated greater accuracy in implant placement. However, further research is needed to enhance the availability of guides for cases with unfavorable residual bone conditions.

Summary: This study found that fully guided orthodontic mini-implant placements supported by tooth-borne guides had higher accuracy compared to gingiva-borne guides in terms of implant angulation. Vertical implant positions showed the lowest deviations. Accuracy values of oral scans were significantly less accurate than CBCT scans.

Summary: This study conducted a randomized controlled trial to compare the accuracy of immediate implant placement using freehand and static guided surgery. The results showed that static guided surgery demonstrated better accuracy in crestal and apical deviations, as well as angular deviations, compared to freehand surgery. However, there was no significant difference in depth deviation between the two groups.

Summary: The study compared free-hand implant planning and placement with computer-assisted implant planning and placement (CAIPP) in achieving the planned implant position. The results showed that CAIPP protocols resulted in smaller deviations regardless of tooth gap size, while in the free-hand group, gap size only influenced angular errors.

Summary: Nowadays, dental implant is widely used in oral rehabilitation, and its success relies on bone density. Cone-beam computed tomography (CBCT) is a well-known method for measuring bone mineral density (BMD) through grayscale values on 3-D images. This study aimed to analyze bone density using CBCT and test its reliability and reproducibility. The results showed that CBCT can be a valuable technique in estimating bone density.

Summary: This study compared the deviations between implant planning and placement using dynamic computer-assisted implant surgery (d-CAIS) and autonomous robotic computer-assisted implant surgery (r-CAIS) methods. The results showed that r-CAIS achieved more accurate implant placement compared to d-CAIS, with no significant difference in patient satisfaction between the two groups.

Summary: The heat pulse method is commonly used to measure thermal properties of frozen soil, snow, or glaciers, but the phase change caused by ice melting affects the measurement accuracy. This study observed the thermal response of ice under different heating strategies and compared numerical simulations and analytical solutions. The results showed that optimizing phase change parameters improved accuracy and the numerical method effectively improved the calculation accuracy of ice thermal conductivity.

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 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: 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.

Summary: When dental patients seek care, not all treatments are successful. Group-based trajectory modeling is a statistical technique that can be used to identify non-responders and different patient groups in longitudinal data sets. This study demonstrated how to use this technique to identify treatment response patterns in patients with a shortened dental arch.

Summary: The aim of this study was to conduct a systematic literature review and meta-analysis on technical complications and failures of removable partial denture (RPD) therapy. After a systematic literature search, 43 publications were included. The data on technical complications and failures were found to be heterogeneous, and publications with high-quality evidence were limited. Therefore, separate reporting of data on technical complications and failures should be done in future studies for better comparison.
