Implant Options in the United States: A Unique History
The story of breast implants in the U.S. is different from other countries, shaped by regulation, medical advances, and consumer demand.
From 1992 to 2006, saline implants were the go-to option in the United States. During this stretch, the FDA limited the use of silicone gel implants, except for those in clinical trials. So, most women seeking breast augmentation or reconstruction had saline implants.
Other countries continued to use silicone and experiment with new gels during this period. This led to big differences in the types of breast implants and techniques used inside versus outside the U.S.
Here’s what set the U.S. approach apart:
- Regulation: Silicone gel implants had restricted access after concerns about their safety.
- Saline popularity: Surgeons and patients became experts with saline, developing placement methods to make them look and feel as natural as possible.
- Innovation: As other countries moved ahead with gel designs and textured options, the U.S. market played catch-up once silicone returned in 2006.
Since 2006, U.S. patients have had greater access to silicone gel implants, including the so-called “gummy bear” options. The introduction of fifth- and sixth-generation implants is changing surgical results and the choices that patients have during consultation.
Saline Implants: What You Need to Know
Saline implants use a silicone shell filled with sterile salt water (saline) during surgery. This simple design is safe and easy to understand. For over a decade, saline was the default choice for American women because it was seen as the safest option.
Structure and Customization
Saline implants are inserted into the body while empty, then filled to the desired size through a built-in valve. The filling is done with saline solution (similar to what’s given in a hospital IV), allowing your surgeon to adjust the volume, sometimes even during the operation.
Pros and cons of saline implants
| Feature | Pros | Cons |
| Customizable Size | Surgeon controls fill volume | Can be over- or under-filled |
| Leak Detection | Immediate, visible (flat tire effect) | Leaks more likely at fill valve |
| Feel | Consistent yet firm | Often stiffer, less natural |
| Appearance | Can be tailored | Rippling, water balloon look at edges |
| Incision Size | Small, implant goes in empty | N/A |
| Placement | Usually under muscle for best results | Over muscle increases rippling risk |
Pros:
- Wide range of sizes: The surgeon can “overfill” for firmness or underfill for softness, customizing the final size.
- Smaller incision needed: Implants go in empty, which helps minimize the surgical cut.
- Detecting leaks is easy: If the shell leaks, saline is harmlessly absorbed by the body and the implant quickly deflates—like a flat tire.
Cons:
- Firmer feel: Saline implants are often stiffer than modern gels, which can feel less natural, especially for women with little existing breast tissue.
- Visible rippling: The edges may show ripples, particularly in thinner patients or those choosing larger implants.
- Higher leak rates: Leaks, while easy to spot, happen a bit more often because of the filling mechanism.
- Aesthetic challenges: Saline sometimes gives a “water balloon” look, especially if the implant is placed above muscle or is very large.
Enhancement Strategies with Saline
To make saline implants look and feel more natural, surgeons commonly place them under the muscle. This adds an extra cushion of tissue over the implant, helping to hide edges and reduce firmness. However, this surgical technique can mean a more involved recovery.

Fifth Generation Implants: The First Big Leap Forward
When silicone implants returned to the U.S. market, they arrived in a new form: the fifth-generation “gummy bear” implant. This name refers to the soft, stable, and cohesive gel inside these implants. Think of the gel like a gummy candy that keeps its form, even if cut in half.
Why Gummy Bear Implants Matter
Gummy bear implants use highly cohesive silicone gel that stays together, even if the outer shell is damaged. Early versions were shaped with a natural breast contour, but now they’re available in both round and anatomical (shaped) options.
Benefits of Fifth Generation Gummy Bear Implants
- Safety: The cohesive gel stays within the shell even if a tear develops, reducing the risk of spreading to surrounding tissue.
- Soft, natural feel: Modern gels strike a balance between softness and shape retention, helping to avoid the “fake” or “hard” look.
- Reduced rippling: These implants are less likely to show ripples, especially compared to saline.
- Low risk of leak detection issues: Leaks are rare, and the gel’s cohesiveness makes them easier to manage if they do occur.
Profiles and Sizes
Fifth-generation implants come in different profiles (low, moderate, high) that affect how much the implant projects from your chest.
They’re available in sizes ranging from about 150cc up to 800cc or more, with brands tweaking size ranges and shapes.
Placement Options
With the improved feel and stability of gummy bear implants, surgeons gained the freedom to try new placements:
- Under the muscle (submuscular)
- Partial under the muscle (dual plane)
- Above the muscle (subglandular)
This flexibility gave more control for creating natural or full looks, depending on the patient’s preference.
Saline vs. Fifth-Generation Gummy Bear Implants
| Feature | Saline Implants | Fifth-Gen Gummy Bear Implants |
| Material | Salt water in silicone shell | Highly cohesive silicone gel |
| Feel | Firmer, sometimes stiff | Softer, more natural, less rippling |
| Leak Detection | Immediate, obvious | Rare, but gel stays inside |
| Customizable Size | Intraoperative filling | Multiple sizes, profiles |
| Incision Size | Small | Slightly larger, prefilled |
| Placement Options | Best under muscle | Can go above or below muscle |
| Appearance | May ripple, less natural | Fuller, tailored, natural styles |
Sixth Generation Implants: The Latest Innovations
Sixth-generation implants have brought significant upgrades by blending the stability of “gummy bear” gel with an even softer, more natural movement.
Major Brands and Unique Features
Leading sixth-generation brands include:
- Motiva
- Sientra
- Mentor
- Allergan
Each brand offers implants with unique variations on shell strength, gel consistency, and surface design, but the core innovations remain consistent.
What’s New with Sixth Generation?
Softness and Movement
- Progressive gel technology: These implants use layers of gel with slightly different firmness. The result feels more like natural breast tissue and flows with the body’s movement.
- 100% filled shell: By fully filling the implant shell, makers reduce the chance of rippling or edges showing.
Safety Measures
- Mono-block technology: The implant’s shell and gel fuse together as one piece, making the structure strong and stable.
- Blue seal: This visible mark helps spot any leaks during checkups and adds a layer of security.
- Strong shell material: Improved shells lower the risk of breaks and decrease scar tissue hardening (capsular contracture).
Surgical Flexibility
With better control over rippling and shape, surgeons can now place these implants above or below the muscle, depending on each patient’s unique anatomy and needs. This opens the door for less invasive, faster-recovery procedures.
Perfect for “Ozempic Breast” and Weight Loss Patients
Patients who’ve lost a lot of weight, especially those using GLP-1 medications like Ozempic, often have less natural breast tissue. Sixth-generation implants:
- Provide structure and fullness without excessive firmness.
- Add softness to thin tissue, restoring volume lost from weight changes.
- Reduce visible implant edges thanks to cohesive gel and full shells.
Key Features of Sixth Generation Implants
- Natural flow, soft feel: Blends cohesive structure with comfortable movement.
- Custom profiles and sizes: Multiple heights, widths, and shapes for fit.
- Mono-block build and blue seal: Improved safety, easy leak checks.
- Lower capsular contracture risk: Scar tissue forms less often.
Quick Look: Improvements Over Fifth Generation
- Even softer feel with the same reliable shape.
- Smoother movement and more natural “settling” in the breast.
- Less noticeable edges or ripples, especially in thinner patients.
- More choices for above-muscle placements, less invasive surgeries, and quicker recovery.
Comparing Implant Generations: Which Implant Suits You Best?
Picking the “right” implant means matching your body, goals, and lifestyle. Here’s a quick comparison:
| Feature | Saline | 5th Gen Gummy Bear | 6th Gen Progressive Gel |
| Material | Saline in shell | Cohesive silicone gel | Upgraded cohesive gel |
| Feel | Firm, can be stiff | Soft, less rippling | Softest, natural movement |
| Leak Detection | Immediate (flat tire) | Gel stays in shell | Blue seal, easy detection |
| Rippling Risk | Higher | Lower | Lowest |
| Customization | Adjustable in surgery | Lots of profiles & sizes | Largest range/profiles |
| Placement options | Mostly under muscle | Under, partial, above | Wide flexibility |
| Incision size | Smallest (goes in empty) | Slightly larger (prefilled) | Comparable or smaller |
| Best for | Those wanting ultra-safe or incisions as small as possible | Fullness, natural results | Preserving breast shape, post-weight loss |
How to Decide:
- If you want maximum control during surgery and spot a leak right away, saline works well.
- If you value a soft, natural shape with less risk of rippling, fifth or sixth-generation implants are hard to beat.
- If you’ve lost weight or want subtle fullness without going bigger, the newer sixth-generation options offer the best natural contour and recovery.
“I just want to improve the overall shape. I really don’t want to be any bigger.” This is a common request, especially as more patients come in after major weight loss or focus on enhancing their existing figure, not just size. Today’s implants and placement techniques make those outcomes possible.
The Future of Breast Implants and What’s Next
Breast implant technology keeps moving. We’re likely to see:
- Even more precise shapes and sizes—larger options, but also smaller, subtler enhancements.
- Continued lowering of risks for rippling, leaks, and capsular contracture.
- Easier, faster recoveries from less invasive procedures.
- More personalized planning, matching implant structure with your anatomy and vision, whether you’re aiming for a dramatic change or restoring a fuller, natural look.
