Abstract
Abstract. Determining occlusal surface relief indicator plays an important role in odontometric tooth shape analysis. An analysis of the parameters of surface relief indicators provides valuable information about closure of dental arches (occlusion) and changes in structure of teeth in lifetime. Such data is relevant for dentistry or anthropology applications. Descriptive techniques commonly used for surface relief evaluation have limited precision which, as a result, does not provide for reliability of conclusions about structure and functioning of teeth. Parametric techniques developed for such applications need special facilities and are time-consuming which limits their spread and ease to access. Nevertheless the use of 3D models, obtained by photogrammetric techniques, allows attaining required measurements accuracy and has a potential for process automation. We introduce new approaches for determining tooth occlusal surface relief indicator and provide data on efficiency in use of different indicators in natural attrition evaluation.

Measurements are more often becoming essential in dental treatment
The other – odontometric – depicts physical sizes of teeth and is applicable in dentistry, anthropology, forensic dentistry and other disciplines related to biometric knowledge, traditional or present-day (Naidu and Freer, 2013; Paredes et al, 2015; Zubov, A.A., 1968)
Odontometry has provided important data applied in prosthodontics (Marxkors, 2003), studies of teeth durability (Khera et al, 1990), studies of attrition (Khan and Young, 2011), in tooth modelling (Lomiashvili and Ayupova, 2008) and etc
Summary
Measurements are more often becoming essential in dental treatment. Measurement techniques being in use and related to visualisation can be divided in two categories. Our base method of determining the occlusal surface relief indicator was applied in odontometric studies of 1240 tooth sections. We propose new improved approaches to measurement of occlusal surface relief expecting their higher sensitivity, in comparison to the base method, to minor but permanent attritional changes which have, as mentioned before,. The presented approaches naturally derive from originally developed odontometric techniques we have been used for tooth size and angle measurements in our previous studies They encompass positive features of odontotomy and provide parameters for occlusal surface feature evaluation. For image merging procedure it is preferable to use side surfaces of teeth insofar as occlusal surfaces are susceptible to functionally caused morphological changes
