“…Various methods, such as 3D-stereophotogrammetry 19 , 21 , Moire topography 22 , optical surface scans 23 , laser scanning 24 , 25 , and CBCT scans 6 , 9 , 19 , have been introduced to acquire 3D facial soft tissue data. In this study, CBCT was used for soft tissue data acquisition because the subjects underwent CBCT taking for the extraction of wisdom teeth.…”

“…Therefore, in the cosmetic field, the degree of skin shrinkage or skin elasticity is often evaluated using 3D-stereophotogrammetry 21 and Moire topography methods 22 , limiting radiation exposure. If the clinician uses only soft tissue procedures, such as botulinum toxin or fillers, laser scanners are often used as a simple method 24 , 28 . Previous studies defined soft tissue landmarks based on the underlying hard tissue structures; consequently, if there is no hard tissue data, clinicians cannot detect soft tissue landmarks 29 .…”

Current method of analyzing three-dimensional soft tissue data, especially in the frontal view, is subjective and has poor reliability. To overcome this limitation, the present study aimed to introduce a new method of analyzing soft tissue data reconstructed by marching cube algorithm (Program S) and compare it with a commercially available program (Program A). Cone-beam computed tomography images of 42 patients were included. Two orthodontists digitized six landmarks (pronasale, columella, upper and lower lip, right and left cheek) twice using both programs in two-week intervals, and the reliability was compared. Furthermore, computer-calculated point (CC point) was developed to evaluate whether human error could be reduced. The results showed that the intra- and inter-examiner reliability of Program S (99.7–100% and 99.9–100%, respectively) were higher than that of Program A (64.0–99.9% and 76.1–99.9%, respectively). Moreover, the inter-examiner difference of coordinate values and distances for all six landmarks in Program S was lower than Program A. Lastly, CC point was provided as a consistent single point. Therefore, it was validated that this new methodology can increase the intra- and inter-examiner reliability of soft tissue landmark digitation and CC point can be used as a landmark to reduce human error.

“…A 3D digital image of each wound (treated with T1 and T2) was taken every 4 days using a 3D camera (3D LifViz®mini Quantificare, Biot, France), commonly used in human medicine for maxillofacial surgery [ 16 ]. This camera uses two laser beams which indicate the optimal distance for image acquisition when the beams converge to a single point.…”

Objectives To evaluate secondary intention wound healing in the horse’s limbs when treated with the synthetic epidermis spray (Novacika®, Cohesive S.A.S, France) or with a standard bandaging technique. Methods Six Standardbred mares were included in the study. Four 2.5 x 2.5 cm full-thickness skin wounds were created on each thoracic limb. Two wounds were located on the dorsoproximal aspect of the cannon bone and the other two at the dorsoproximal aspect of the fetlock. Six hours after creation, wounds were randomly treated with synthetic epidermis spray or standard bandaging. The wounds were assessed every 4 days by gross visual assessment and using a 3D imaging camera. Analysis was performed with a 3D imaging application. Results Out of 46 wounds, 22 showed exuberant granulation tissue and were part of the standard bandaging group. Whether the wounds were treated with synthetic epidermis spray or standard bandaging, the time for healing was the same. Conclusion The synthetic epidermis spray studied in this model has allowed healing without the production of exuberant granulation tissue but did not reduce the median wound healing time compared to a standard bandaging technique. The synthetic epidermis spray is potentially an interesting alternative for the management of secondary intention wound healing of superficial and non-infected distal limb wounds in adult horses on economical and practical aspects. However, all statistical inference (p-values especially) must be interpreted with caution, given the size of the sample.

“…Although passive SPG represents a valid, reliable tool for detecting volume changes, its accuracy decreases with small volume comparisons, periorbital/midfacial regions, and in-vivo measurements. 2 Despite the high degree of reliability of modern 3D imaging systems, SPG measurements are still prone to error, with a coefficient of variation between 2.8% and 6.8%. 3,4 In clinical use, SPG may miscalculate volumes by 0.2-2 mL, with smallest detectable changes ranging from 1.5 to 6 mL in the midface.…”
