Abstract
Abstract. Over the past few years closer cooperation can be observed in various aspects of digital techniques in such disciplines as dentistry and anthropology. And in most cases that consists in imaging and image processing which results in obtaining 3D reconstructions. And indeed, they can significantly improve research and practice. Thus, depending on imaging technique and application, they can support CAD/CAM technology or precisely reconstruct morphology of invisible structures. However the currently presented study refers to technical aspects of shade and texture mapping, which is more aimed to obtain more realistic 3D reconstructions of palaeoanthropological material. Colour or shade matching has become an integral part of dental practice. It can be carried in a traditional manner though matching the tooth with conventional shade-guides, or, which is in line with the subjects of our study, by means of spectrophotometry. And the main procedures of shade detection have been performed by SpectroShade (MHT). Necessary attention has been paid to conditions influencing shade detection process with respect to the studied material teeth taken from the Bronze Age findings. Reconstructive techniques have traditionally been a scientific and practical part of palaeoanthropological research which is directed at appearance reconstruction. Though the leading part of this branch has been always aimed at analysis of skull morphology. In our time of rapidly developing digital techniques reconstructions have become to a large extent a matter of improvements of imaging and image processing techniques. Even though this doesnt directly refer to soft tissue reconstruction, it undoubtedly applies to dental reconstructions. And the current study presents improvements in reconstruction through combining imaging with shade and texture mapping on 3D models of teeth.
Highlights
Dental studies have become more intense over the period of recent years in terms and through cooperation between different scientific and practical disciplines
This can be illustrated once again by the current study where shade matching methodology and technology developed for practical applications in dentistry has been transferred to reconstruct palaeoanthropological material
The currently presented study which deals with shade matching and its application in palaeoanthropology is an example of such cooperation
Summary
Dental studies have become more intense over the period of recent years in terms and through cooperation between different scientific and practical disciplines. Especially taking into consideration rapid advances in digital techniques, the connecting link is provided by 3D imaging and image processing They improve many aspects in practical dentistry as well as in anthropological and dental research. The focus is usually concentrated on obtaining accurate, highresolution reconstructions This is undoubtedly important from technological point of view (Beyer, 2019) or in terms of detailed reconstruction of the smallest structures which are necessary for studies or methodological improvements (Gaboutchian et al, 2020 b). There are other aspects which come to the fore in order to add value to traditional workflow This can be illustrated once again by the current study where shade matching methodology and technology developed for practical applications in dentistry has been transferred to reconstruct palaeoanthropological material
