Removal of artifacts arising from reflections for intraoral scanner

A three-dimensional (3D) scanner system comprising:

• an intraoral scanner comprising:
• an elongate wand comprising a distal end configured for insertion into an oral cavity, wherein the elongate wand comprises a means for light to enter and exit the intraoral scanner;
• and
• a means for preventing contact between internal components of the intraoral scanner and the oral cavity, wherein the means for preventing contact between the internal components of the intraoral scanner and the oral cavity is a transparent means that also enables the light to enter and exit the intraoral scanner;
• and
• a means for:
• a) receiving one or more two-dimensional (2D) images generated by the intraoral scanner, the one or more 2D images comprising a) captured structured light reflected off of an intraoral object and b) captured additional light arising from reflections from the means for preventing contact between the internal components of the intraoral scanner and the oral cavity;
• and
• b) performing three-dimensional (3D) image reconstruction using the captured structured light in the one or more 2D images while excluding the captured additional light in the one or more 2D images based on processing of the one or more 2D images using one or more algorithms.
