Do textured round and textured teardrop implants feel the same? Do teardrop implants have good cleavage?

We are fortunate to have variety of options for aesthetic breast augmentation because everyone is different and has different needs.  In general the pros of the textured is as follows:
1.  It may decrease the risk of capsular contracture.
2.  Because it integrates with the tissues around it, will migrate less with time and reduce the risk of implant “bottoming out”.
3.  The anatomical textured has the shape that most patients want, which is tear drop shaped.  In patients who rely on implant to shape the breast, it may be of advantage.  
For the smooth implants, the pros are as follows:
1.  It decreases the risk of rippling especially in patients with very little soft tissue coverage.  
2.  For patients with very short lower pole, the “settling “will stretch the lower pole with time.
3.  The occurrence of the Breast implant-Anaplastic Large Cell Lymphoma seems to be significantly less than textured.  
Because there are so many choices and factors to consider, not just the type and size of the implant, it is very important to seek an experienced Board certified plastic surgeon.

Thank you for the question. 
These days there are a variety of breast implants available; the variety of breast implant available raise a lot of questions from women considering breast augmentation surgery. Personally, I think that for most patients considering breast augmentation surgery, careful selection of plastic surgeon and careful communication of goals, far outweigh the specific type of breast implant utilized (when it comes to the success of the breast augmentation procedure).
Anatomical breast implants were designed to better simulate the natural breast shape; the problem with these implants is that if they shift or rotate, the entire breast will change shape as well. This change in breast shape may require further surgery to correct. Round implants, under the hand, can shift or rotate without changing the shape of the breasts. ***Overall, I find that beautiful outcomes can be achieved with the use of round saline or silicone gel breast implants for the vast majority of patients.
Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery ( regarding breast implant size/profile selection) is:
1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. For example, I have found that the use of words such as “very natural” or "C or D cup" or "good cleavage" etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. Again, the use of computer imaging has been very helpful during the communication process, in our practice.
3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, after the use of temporary intraoperative sizers.
I hope this helps. Best wishes for an outcome that you will be very pleased with. 

Gummy bear implants are a variant of silicone implants. The difference being a form stable gel fill which imparts the anatomic shape. 
The simple answer to your question is: the devices feature silicone gel fills of differing cohesivity. The gummy bear gel is the most cohesive/firm available. It is form stable and will hold a shape thus the shaped/gummy bear. So there is a difference in feel, primarily.
In my practice most patients will choose a smooth round device. When placed in the submuscular plane, the aesthetic differences are minimal. The downward pressure by the muscle across the upper pole of the round device forces it to assume a more tear drop appearance. Recent studies have shown that both patients and surgeons have difficulty distinguishing between the 2 implant types post-operatively. Additionally, shaped implants are more costly and have an increased risk of rotation.
Finally, although very rare, the few documented cases of BIA-ALCL (Breast Implant Associated Anaplastic Large Cell Lymphoma) have all been in cases of textured devices. Until more data is available many are shifting their practice back to smooth round devices.
Studies have shown most cannot tell the difference between the shaped and round devices when placed submuscular. In light of the added cost, larger incision, and BIA-ALCL risk...most will opt for round devices.As always, discuss your concerns with a board certified plastic surgeon (ABPS).
