Summary: The study aimed to determine the accuracy of partially and fully guided surgical techniques for immediate implant placement into fresh sockets and compare two different methods of implant position deviations analysis. The partially guided technique resulted in significantly higher deviations compared to the fully guided technique in both tomographic and digital scanning analysis. More studies are needed to validate and define the most reliable method of measuring implant deviation.

Summary: The study evaluated the accuracy of computer-guided implant surgery associated with prototyped surgical guides. Results showed no significant difference between the virtual and real positions of the implants, with a tendency towards greater error in the mandible compared to the maxilla in terms of angular, central, and coronal deviations.

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: 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: The aim of this study was to investigate the accuracy of an implant surgical guide digitally designed by using data from cone beam computed tomography (CBCT) scans and milled with a 5-axis CNC machine. The results showed that the average deviation of the surgical guide was 0.16 +/- 0.06 mm, indicating acceptable precision.

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: The study compared the accuracy of implant placement using a surgical motor or a torque wrench as part of a half-guided surgical protocol. While there was no significant difference in accuracy and mean insertion torque between the two groups, machine-driven implant placement was found to be significantly less time-consuming.

Summary: Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy has revolutionized survival and quality of life in peritoneal carcinomatosis patients. Preoperative CT is crucial for patient selection and surgical planning. Radiologists play a key role in describing cancerous implants, analyzing involvement patterns, and estimating disease burden during CT interpretation, enhancing disease understanding and communication between radiologists and surgeons.

Summary: The aim of this study was to assess the eruption path and development of the maxillary canine following alveolar bone grafting in patients with cleft lip and palate. The study found that higher angulation of the canine on the cleft side indicates a higher risk of future canine impaction. The presence or absence of the lateral incisor did not significantly affect canine angulation or its vertical eruption.

Summary: Objective Tooth segmentation and classification from cone-beam computed tomography (CBCT) is a prerequisite for diagnosis and treatment planning in digital dental workflows. This study validated an automated deep convolutional neural network (CNN)-based tool for segmenting and classifying teeth with orthodontic brackets on CBCT images. The CNN model outperformed other algorithms in terms of accuracy and efficiency, making it a viable alternative for automatic tooth segmentation and classification.

Summary: This study aimed to identify local radiographic risk factors for Medication-Related Osteonecrosis of the Jaws (MRONJ) in osteoporotic patients undergoing tooth extraction while being treated with antiresorptive drugs. The results showed that tooth extraction sites with radiographic signs of chronic dental infection are prone to MRONJ. Additionally, factors such as gender, smoking, location in the mandible, radiolucent or sclerotic trabecular pattern, complex extractions, root remnants, and unrestored caries lesions were also associated with the development of MRONJ.

Summary: This study assessed the radiographic presentation of anatomical structures, bony changes, and soft tissue calcifications on panoramic radiographs of oncologic patients under high dose antiresorptive drug therapy (ART) before tooth extraction. The results showed that patients under ART had more sclerotic bone patterns in the mandible and posterior maxilla, as well as thicker mandibular cortices. However, there were no differences in the visibility of anatomical structures and presence of soft tissue calcifications among groups. Therefore, it is suggested that the sclerotic bone pattern and thicker mandibular cortices may be a consequence of ART rather than specific findings of medication-related osteonecrosis of the jaw (MRONJ).

Summary: The study assesses the accuracy of sleeveless guided endodontics for root canal treatment in 3D printed jaws with severe pulp canal obliteration (PCO). The results show that sleeveless guides can accurately guide the endodontic treatment and there is no significant difference between operators. The study suggests that sleeveless guides offer a valuable alternative to conventional endodontic guides with similar accuracy results.

Summary: The aim of this study is to evaluate the accuracy of a novel augmented reality (AR) method for guided access cavity preparation in 3D-printed jaws. Two operators with different levels of experience performed virtually guided access cavities using an AR system on 3D-printed jaw models. The results show promising results for the use of AR as a digital guide in endodontics, but further research and development may be needed.

Summary: This study found that paediatric dentists had poor diagnostic accuracy when using CBCT without specific training, with higher sensitivity observed when using 2D images. Sensitivity was high for diagnosing apical pathology and root fractures, but low for inflammatory root resorption, root cracks, and subluxations. Additional training in radiographic diagnosis is necessary for paediatric dentists to improve diagnostic performance, especially when using CBCT.

Summary: This study compares the trueness of skull models fabricated using different technology and cost segments of 3D printers. It finds that medium to high-cost stereolithography and material jetting printers have optimal trueness for patient-specific treatment planning in craniomaxillofacial surgery. On the other hand, low-cost fused filament fabrication printers are suitable for anatomical education and/or patient communication.

Summary: The aim of this study was to introduce an objective method for evaluating the accuracy of implant position assessment in partially edentulous patients. Different techniques (conventional impression, intraoral scan, CBCT) were compared to an industrial scanner to obtain a reference 3D model. The results showed that all assessment techniques deviated from the reference industrial scan, with intraoral scans being slightly less accurate than both conventional impressions and CBCT.

Summary: This study validates the use of an intraoral scan (IOS) post-operatively compared to the gold standard Cone Beam Computed Tomography (CBCT) in measuring the accuracy of guided endodontics. Clinical data shows high accuracy of guided endodontics with mean apical deviation less than 0.5 mm and mean angular deviation less than 2 degrees. Hence, IOS can be used to assess the accuracy of guided endodontics.

Summary: Accurate detection of the mandibular canal is crucial for avoiding nerve injury during surgery, especially in the complex interforaminal region. In this study, an AI-driven tool was trained and validated to accurately segment the mandibular canal, even in the presence of anatomical variations such as the anterior loop. The results showed high accuracy metrics, indicating that the AI tool can significantly contribute to presurgical planning for dental implant placement.

Summary: The aim of this study was to assess the symmetry of skeletal midfacial complex in skeletal class I patients. The results showed that female patients had a more symmetrical midfacial complex compared to male patients. The comparison between true and mirrored models justified the applicability of using the mirroring technique in reconstructive surgical procedures.
