Summary: The study assessed the positive predictive value of panoramic radiographic signs in determining the relationship between impacted mandibular third molars (IMTMs) and the mandibular canal (MC). Results showed that root apex darkening and interference with the white line on panoramic radiographs had a high PPV for detecting the contact between IMTMs and MC. Presence of these risk factors indicates the necessity for subsequent 3D radiographic assessments.

Summary: This study compared panoramic radiography and cone-beam computed tomography for evaluating the roots of maxillary third molars and their relationship with the maxillary sinus. The study found that panoramic radiography can reliably determine the number of roots and root morphology but does not provide radiographic signs related to the anatomical relationship with the maxillary sinus.

Summary: The development and common use of radiology, rapid prototyping, and 3D printing in dentistry have inspired the improvement of diagnostic and therapeutic processes. A comparative analysis was conducted on dental panoramic radiographs, cone-beam computed tomography, and 3D printing in assessing the difficulty of surgical procedures, showing that linear measurements in dental panoramic radiographs were significantly lower than in CBCT and 3D models. Overall, the results suggest that the elective procedure of removing impacted mandibular third molars may be safe based on insignificant differences in measurements between 3D models and CBCT images.

Summary: This study aimed to analyze the role of preoperative Cone Beam CTs in the surgical removal of complex lower third molars and to evaluate the impact of nerve injuries and neurological disorders. The results show that CBCT does not significantly affect the risk for complications during surgery and should only be used for risk assessment. Additionally, exposure of the inferior alveolar nerve bundle during surgery does not necessarily predict neurological damage.

Summary: This study evaluated the impact of CBCT information on the treatment plan for maxillary second and third molars. Severe resorption in the second molar was found to significantly influence the treatment plan. Logistic regression analyses identified mesioangulation of the third molar, marginal bone loss, superficial resorption, and age as significant factors for deciding whether to remove the third molar. Severe resorption was also found to be significant in determining whether to remove the second molar instead of the third molar.

Summary: This study aimed to identify risk factors associated with perforation of the undercut (U)-shaped lingual plate (LP) by the lower third molar (LM3) root using panoramic radiography (PAN). The study found that men aged over their midtwenties with Class I/II impaction and mesioangularly or horizontally impacted LM3s, along with root darkening and no interruption of the white line on PAN, have a higher risk of U-type LP perforation.

Summary: The study found a high correlation between tooth-related findings in CBCT and clinical findings, but a low positive predictive value and likelihood ratio for canal-related variables. The highest positive predictive value and likelihood ratio were found when the mandibular canal was positioned between the roots of the third molar.

Summary: Dental CBCT and panoramic images are important for dental diagnosis and treatment planning. This study proposed a method of reconstructing a panoramic image by extracting panoramic projection data from dental CBCT projection data. The method was successfully applied to various patients' CBCT data, providing a universally applicable panoramic image.

Summary: The study examined the tensile properties of potential printing materials for FFF according to ISO527 and investigated the structural integrity of 3D-printed prostheses according to ISO10328. Tough PLA was identified as the most suitable print material, and FFF using Tough PLA can create transtibial prostheses that almost comply with the International Standard for Structural Testing of Lower Limb Prostheses.

Summary: This systematic review evaluates the use of 3D printing in producing limb prostheses in lower-income countries and lower-middle-income countries (LLMICs). The results of 18 studies show that 3D-printed prostheses have the advantages of low material costs, aesthetic appearance, and personalized fitting. However, the lack of (homogeneous) data highlights the need for more published (scientific) research to increase the availability of knowledge about 3D-printed prostheses for LLMICs.

Summary: This report describes a workflow to produce low-cost 3D-printed transtibial prosthetic sockets, which can be easily produced in rural areas using computer-aided design and manufacturing technologies. The size of the socket was scanned and printed using 3D printing technology. The cost of the 3D-printed socket is $20, and the total cost is approximately $100. This report provides a blueprint for producing low-cost 3D-printed transtibial prosthetic sockets.

Summary: This study compared the characteristics of mandibular asymmetry between patients with unilateral craniofacial microsomia (CFM) and class II asymmetry. The CFM group showed significantly larger size asymmetry in the mandibular body, ramus, and condyle compared to the Class II group. The positional asymmetry of mandibular body, including roll rotation and occlusal and mandibular plane cants, was also greater in CFM. These findings suggest that mild CFM has more severe size asymmetry and roll rotation in the mandible compared to non-CFM class II asymmetry.

Summary: The study aimed to assess the reproducibility of manually transferring the clinical natural head position (NHP) to the 3D virtual surgical planning and its subsequent influence on the soft tissue and maxillary hard tissue position. The study found that the reproducibility of manually aligning the NHP was lower for pitch alignment compared to roll and yaw alignments, and this alignment error affected the position of the maxilla and soft tissue.

Summary: Research findings suggest that the application of AR in patient education can improve knowledge retention and patient satisfaction. Patients generally like this technology and are willing to use it in education. The quality of the existing research results is moderate, and more high-quality studies are needed to fully assess the value of AR in patient education.

Summary: This study compared the location and motion of pessaries in women with pelvic organ prolapse (POP) who had successful and unsuccessful pessary treatments using dynamic magnetic resonance imaging (dMRI). The findings indicated that non-fitting pessaries were positioned lower at rest and showed more clockwise rotation and downward movement during Valsalva, suggesting that the dynamic characteristics of the pessary may play a role in its effectiveness.

Summary: This study evaluated the 3-year esthetic outcome of flapless immediate implant placement and provisionalization (FIIPP), and found that it may increase the risk of buccal soft-tissue recession. By installing implants in a maximal palatal position and filling the gaps with bovine bone substitute, high patient satisfaction and good soft-tissue esthetics were achieved after three years. Factors such as implant location, gap size, and emergence profiles were associated with the esthetic outcome.

Summary: This study analyzed the value of a 3D printed lung model in understanding and teaching anatomy. The results showed that experienced surgeons performed equally well with both 2D and 3D models. However, fellow surgeons benefited greatly from the 3D model, showing improved accuracy, shorter completion time, and increased confidence. Junior residents also showed shorter completion time and increased confidence, but no improvement in accuracy.

Summary: This study compared the skeletal structures of mandibular prognathism and retrognathism in patients with facial asymmetry. The results showed that the condylar heads were located more posteriorly, inferiorly, and medially in the retrognathism group compared to the deviated prognathism group. The asymmetric mandibular body length was significantly correlated with chin asymmetry in retrognathic asymmetry patients, while the asymmetric elongation of the condylar process was the most important factor for chin asymmetry in deviated prognathism.

Summary: This study evaluated the surgical accuracy of 3D virtual surgical planned orthognathic surgery and its relation to a learning curve, specifically considering posterior impaction and magnitude of planned movements. The results showed an annual increase in surgical accuracy from 2016 to 2020, particularly in vertical translations and yaw rotations. Furthermore, a less favorable learning curve was observed with posterior impaction and greater magnitude of movements.
