A scanner for scanning a dental site comprises a base, a detector mounted to the base, and an optical element to redirect light reflected off of the dental site towards the detector along a detection axis in a first direction. Two or more flexures couple the optical element to the base, wherein thermal expansion or contraction of the optical element with respect to at least one of the detector or the base bends each flexure of the two or more flexures in a respective second direction without bending the flexure in a respective third direction approximately perpendicular to the first direction and the respective second direction, wherein the two or more flexures maintain an alignment of the optical element to the detector with changes in temperature.
