I want to rebuild my temple points. How do I need to measure to be able to have a natural and somewhat receding look?

Filling in the temple points is often important in a good hair transplant. If, as you say, you don't have temple points anymore then you likely would benefit from adding temple points to balance with your newly transplanted hairline. An experienced hair transplant surgeon should be able to help you determine what you need.

Temporal peaks are placed projection of the most lateral point of eye...I personall y just follow the route and alignment of preexisting hair in order to create the new frontal hair line and temples.. So it is the important point that to find an experienced surgeon.. But ıf you have an idea about the place of temporal point (not the temporal peak) : The lateral temporal point exist in intersection of 2 lines , one pass through between tip of the nose and pupil of eyes and another line passes between earlobe and midpoint of frontal hair line ..

Temple points can be very important in the aesthetic redesign of the male hairline. The good news is that a skilled surgeon will have the skill to know how to design the temple points and this is not something you will need to measure.
