Loss of sensation is not very common. It can happen when placing implants.
On the other hand, short term sensory change is quite common. This may be due to swelling and usually gets better within a few weeks after surgery.
One theory: The larger the implant, the more likely it could happen. This may be due to stretching of the tissues ans subsequently the sensory nerve fibers that go to the nipple. There is no strong evidence suggesting any one incision is more likely to cause it.
