Round vs. Teardrop? (Photo)

The Round Base High Profile implant from Sientra is made for you. Gives more roundness with its high profile, but has a slight slope to the upper pole which can add an element of 'natural' otherwise not achieved with a round implant. Mentor has similar, but slightly oval (wider than tall), and Allergan implants, imo, are too stiff/hard in their shaped versions. Best. 

You can have a natural look with a smooth round implant placed under the muscle without sacrificing upper pole fullness.
