Summary: The aim of this study was to compare the accuracy of intraoral scan system (IOS) with prefabricated aids and stereophotogrammetry (SPG) compared with open tray implant impression (OI) for complete-arch implant-supported fixed dental prostheses (CIFDP). The results showed that the accuracy of SPG and IOS with prefabricated aids were comparable, but IOS had the most efficient workflow.

Summary: This study describes a protocol for computer-assisted surgery in complex temporomandibular joint reconstruction. The protocol includes preoperative assessment, imaging acquisition, virtual surgical planning, and intraoperative transfer. The results show that this method reduces complications and pain, and improves patients' interincisal opening and masticatory function. In conclusion, this protocol is a safe and reliable surgical management modality, but further research is needed to validate its usefulness and indications.

Summary: The aim of this study was to investigate the precision of implantation on a phantom head according to preliminary planning and the influence of participants' knowledge and experience. Implants were scanned and compared to the 3D-planned placement to measure deviations. The results showed that both implantologists and students had deviations less than 1.78 mm on average from 3D planning, demonstrating the predictability and reproducibility of guided implantology in dental implantology.

Summary: The accuracy of static computer-assisted implant surgery (sCAIS) for tooth-supported free-end dental implantation was evaluated in this study. The use of surgical guides with or without fixation pins can provide clinically acceptable outcomes in terms of accuracy in implant position. Statistically significant differences were found in the accuracy of implant position when utilizing fixation pins only for horizontal apical and depth deviation, as well as between the planned and the 3D printed surgical guide when considering the sleeve position.

Summary: A digital approach is described for fabricating a splinted framework and custom open tray for multiple implant impressions. By digitally scanning and aligning impression copings to a preliminary cast, a virtual cast is created that offers information about the impression coping positions and their surrounding tissues. This allows for the digital design and fabrication of a splinted framework and custom open tray. The digital approach eliminates the need for traditional manual fabrication procedures, reduces treatment time and cost, and ensures consistent quality.

Summary: This study aimed to evaluate the accuracy of eight impression-making methods for edentulous arches and determine the effects of using a 3-dimensionally printed polyetheretherketone (PEEK) scanning aid on the accuracy of intraoral scanners. The results showed that intraoral scanners demonstrated accuracy comparable with that of conventional impression materials, and the PEEK-based scanning aid improved the accuracy of the intraoral scanners compared to conventional impression materials.

Summary: This study aimed to investigate the effects of implant-analog-holder (IAH) offset, inner structure, and printing layer thickness on the accuracy and positional changes of 3D printed dental models. The results showed that these factors significantly affected the accuracy of the printed models and the positions of the implant analogs. Clinicians can improve printing accuracy and minimize positional changes by considering the recommended IAH offset, inner structure, and printing layer thickness.

Summary: This study investigates the effect of acid etching treatment on the surface microstructure, roughness, and contact angle of zirconia, and compares its effects on the shear bond strength of resin cement. The results suggest that acid etching significantly alters the surface of zirconia and increases the resin cement's bond strength. Therefore, acid etching is a promising method for zirconia surface treatment.

Summary: This study evaluated the effect of surface treatments and adhesion conditions on the long-term use of 3D printing polymers in bonding with resin cements. The optimal adhesion condition for UDMA was achieved with APA and SBU treatments followed by the use of U200 cement, while the adhesion conditions had no significant effect on Bis-EMA. After thermocycling, the SBS significantly decreased in UDMA without APA treatment and in the entire Bis-EMA group. Surface porosity and increased roughness were observed on both material surfaces after APA.

Summary: This study examines the reinforcement effect of recombinant human bone morphogenetic protein-2 (rhBMP-2) applied to collagen membranes in guided bone regeneration. Results show that the combination of collagen membranes with rhBMP-2 and biphasic calcium phosphate (BCP) significantly enhances bone formation rates. The 2-week healing period yields lower bone formation compared to 4 and 8 weeks.

Summary: This study evaluated the clinical usefulness of a freely detachable zirconia ball-and spring-retained implant prosthesis (BSRP) and found it to be a viable treatment option. The implant success rate was 100% and marginal bone resorption was lower in the BSRP group compared to the screw-and cement-retained group. Although periodontal pocket depth was slightly higher in the BSRP group, there was no significant difference from the SCRP group.
