Silicone vs saline, high profile vs moderate profile: What are the pros and cons? (Photos)

One alternative is to place high profile saline implants that can be filled to a larger volume.  However, most plastic surgeons will recommend not having 1000 cc implants due to the long term effects on the tissues.The high profile breast implant is extremely narrow at the base to provide maximum projection. High profile implants yield the fullest and most rounded results, which may look  less natural on some patients. However, high profile implants are often ideal for petite women who have a narrow chest wall.Filling type – You can get silicone gel or highly cohesive
saline gummy bear implants or saline implants. None of these are better
options than the others. However, they do have their differences when
you examine their cost, feel, and incision requirements.  The choice for
implants is really up to you.  There are pros and cons of each which
your PS can explain during your in-office consultation.  If you have a
lot of tissue to cover the implant, the advantages of silicone
for softness and less rippling are not as marked. Shape
– Silicone gel and saline implants are usually round whereas gummy bear
implants can be had in shaped or round choices depending on your
requirements. Shaped implants give a gentle sloping look to breast
profiles whereas round implants result in a fuller upper portion of your
breasts aka the upper pole. Profile – Everyone’s profile is
different and can be chosen based on input from your cosmetic surgeon.
Your doctor will arrive at this decision based on your goals as well as
existing proportions.  This factor actually has very little to do with
the result.  Almost no low profile implant is ever utilized.  Almost all
implants placed are moderate, moderate plus, or high(full) profile. 
Very few ultra high profile implants are used as they may have a higher
probability of thinning tissue over time.  The difference in diameter
and implant height among moderate, moderate plus, and high (or full)
profile implants is very little and may be less than a centimeter in
diameter for a given volume.  Size – Breast implants come in a
variety of sizes that range from 150cc all the way to 800cc and
sometimes even go larger. Most patients need a different breast implant
size for each of their breasts. This is done so that they reach the best
symmetry possible. The size chosen by patients should be based on the
size of your breasts currently, the goals you wish to achieve as well as
input from your cosmetic surgeon. Tall women with larger frames and
broader chest, shoulders, and hips can often handle larger implants that
would make smaller women's chests look overcrowded and heavier.  Placement
- I think that most plastic surgeons would agree that a breast
augmentation result where the implant is placed under the muscle (dual
plane) tends to have better longevity than a breast implant placed over
the muscle.I would recommend that you go with the size
that boosts your self-esteem, and fits your anatomy.  Choosing an
implant based on an aesthetic goal that exceeds your anatomic capacity
may lead to complications and possibly revision.

It isn’t clear what you don’t like about your current result other than you just want to be larger. Although a larger implant may give you more upper fullness they will gradually sag again and then you will need a lift.
