Three-dimensional facial volume analysis using algorithm-based personalized aesthetic templates. AJ Tuin, JW Meulstee, TGJ Loonen et al.

Date: February 2020 (Online). Source: International Journal of Oral and Maxillofacial Surgery. Abstract: Three-dimensional stereophotogrammetry is commonly used to assess volumetric changes after facial procedures. A lack of clear landmarks in aesthetic regions complicates the reproduction of selected areas in sequential images. A three-dimensional volumetric analysis was developed based on a personalized aesthetic template. The…

Collagen 2A Type B Induction after 3D Bioprinting Chondrocytes In Situ into Osteoarthritic Chondral Tibial Lesion. B Gatenholm, C Lindahl, M Brittberg, S Simonsson.

Date: February 2020. Source: CARTILAGE. https://doi.org/10.1177/1947603520903788 Objective: Large cartilage defects and osteoarthritis (OA) cause cartilage loss and remain a therapeutic challenge. Three-dimensional (3D) bioprinting with autologous cells using a computer-aided design (CAD) model generated from 3D imaging has the potential to reconstruct patient-specific features that match an articular joint lesion. Design: To scan a human…

Craniofacial Asymmetry from One to Three Years of Age: A Prospective Cohort Study with 3D Imaging. AM Launonen, V Vuollo, H Aarnivala, et al.

Date: December 2019. Source: Journal of Clinical Medicine, 9, 70; doi:10.3390/jcm9010070. Abstract: Deformational plagiocephaly (DP) is considered a risk factor for facial asymmetry. This cohort-based, prospective, follow-up study used three-dimensional (3D) stereophotogrammetry to assess the development of facial asymmetry in a normal birth cohort and to investigate the impact of DP on facial asymmetry for…
