Abstract: According to a combined intraoral and impression scanning system and method of the present invention, intraoral scan data of an intraoral object can be obtained and stored, and impression scan data of the oral object can be selectively stored from an intraoral scan data area that satisfies a preset determination condition. By applying the intraoral scan data area corresponding to the preset determination condition as the impression scan data, highly reliable final scan data can be obtained and a precise prosthesis can be manufactured.

Abstract: An image processing apparatus and an image processing method, according to the present invention, may sense an identifier positioned in a tip to identify unique information such as a serial number of the tip, and may update tip use information assigned to the identified unique information. In some cases, in connection with updating the tip use information, the use information may also be selectively updated based on the type of a scan target to be scanned. Alternatively, a scanning operation of the image processing apparatus may be restricted when a predetermined elapsed time from the removal to the mounting of the tip after scanning an oral cavity is not ensured. Due to the above-mentioned configuration, a user can conveniently recognize when to replace the tip.
