Breast Implants Explained: How to Choose the Right Type for You

Breast implants are available in three fill types — silicone gel, saline, and structured saline — and two primary shapes: round and anatomical. The right implant for any individual patient depends on their existing breast tissue, chest wall anatomy, body frame, lifestyle, and aesthetic goals. There is no universally superior implant type. The decision is made collaboratively between patient and surgeon during consultation, based on your specific anatomy and what you are trying to achieve.

Why Implant Choice Matters

The implant selected for your surgery is one of the most consequential decisions in the entire process. It affects how your result looks, how it feels, how it ages over time, and what your options are if revision surgery is ever needed. Yet many patients arrive at consultations having already decided on an implant type based on what they have read online or heard from friends — often without the anatomical context that makes one choice more appropriate than another for their specific body.

This guide explains what each implant type actually is, where the meaningful differences lie, and how surgeons approach the decision. The goal is not to tell you which implant to choose — that is your surgeon’s role after examining you — but to give you the knowledge to have a genuinely informed conversation during your consultation.

Implant Fill Types: Silicone, Saline, and Structured

The three available fill types are silicone gel, saline (sterile salt water), and structured saline. Silicone gel implants are the most widely used globally, preferred for their natural feel and appearance. Saline implants offer the safety advantage of harmless absorption if ruptured. Structured implants combine an internal scaffold with saline fill to reduce the rippling common in standard saline implants.

Silicone Gel Implants

Silicone gel implants are filled with a cohesive silicone gel that closely replicates the density and movement of natural breast tissue. Modern implants use a highly cohesive gel formulation — sometimes referred to informally as “gummy bear” technology — where the gel maintains its form even if the outer shell is damaged. This is a significant improvement over earlier generation silicone implants and addresses the primary historical concern about silicone migration.

Silicone implants are available in a wider range of sizes, profiles, and shapes than saline alternatives, giving surgeons more flexibility to tailor the result to individual anatomy. They are the implant of choice for the majority of patients globally and are the most commonly used type in Dubai. The main monitoring consideration is that silicone implant rupture — unlike saline — can be silent, meaning there is no visible change in breast appearance. For this reason, periodic MRI monitoring (every 5 to 6 years) is the recommended standard for patients with silicone implants.

Saline Implants

Saline implants consist of a silicone shell filled with sterile salt water after placement. Because they are filled post-insertion, the incision required is smaller than for pre-filled silicone implants. If a saline implant ruptures, the salt water is harmlessly absorbed by the body and the deflation is immediately visible — which some patients consider a safety advantage as it removes the need for MRI surveillance.

The primary limitation of saline implants is feel. They are firmer than silicone and, in patients with thin skin or limited breast tissue coverage, can show visible rippling or edge definition — particularly along the inner and lower breast. For patients with sufficient existing breast tissue to provide coverage, this is less of a concern. For patients who are slim, have minimal natural breast tissue, or are seeking a subtle, natural result, silicone is generally the more appropriate choice.

Structured Saline Implants

Structured implants — the primary example being the IDEAL IMPLANT — contain an internal baffle structure designed to control the movement of saline and reduce the rippling that standard saline implants can produce. They offer a feel that sits between standard saline and silicone, and retain the advantage of saline in terms of rupture detection and body absorption. They are not as widely available as silicone or standard saline and carry a higher cost. They represent a valid middle-ground option for patients who have specific concerns about silicone but find standard saline unsuitable.

Implant Shape: Round vs Anatomical

Round implants add volume throughout the breast, including the upper pole, and are the most versatile choice for the majority of patients. Anatomical implants — also called teardrop or form-stable implants — are shaped to replicate the natural breast slope, with more projection concentrated at the lower pole. Neither shape is universally superior. The appropriate choice depends on your starting anatomy, the result you want, and your surgeon’s assessment.

Round Implants

Round implants are symmetrical — they look the same regardless of orientation — which eliminates the risk of rotation affecting the result. They add fullness across the entire breast, including the upper pole, and are available in a range of profiles (the degree of forward projection relative to the base width). Because rotation is not a concern, they are compatible with both smooth and textured surfaces and are simpler to place and revise.

Round implants are appropriate for the majority of patients seeking augmentation. They are particularly well-suited to patients who want noticeable upper pole fullness, patients augmenting after volume loss, and patients seeking a moderate-to-significant size increase. The perception that round implants inevitably look artificial is not accurate — projection profile, size selection relative to chest width, and placement technique have far more influence on the naturalness of the result than implant shape alone.

Anatomical (Teardrop) Implants

Anatomical implants are shaped with a graduated slope — less projection at the top, more at the bottom — designed to replicate the natural teardrop profile of the breast. They are form-stable, meaning the gel is highly cohesive and holds its shape. For certain patients — particularly those seeking a subtle, natural result with minimal upper pole projection — they can produce excellent outcomes.

The critical technical consideration with anatomical implants is rotation. Because they are not symmetrical, rotation within the pocket causes visible distortion of the breast shape. To minimise this risk, anatomical implants require a textured surface to create tissue adherence, precise pocket sizing, and a surgeon experienced in placing and managing them. If rotation does occur, surgical correction is required. This is not a common complication in experienced hands, but it is a relevant risk that does not exist with round implants.

Anatomical implants are not the right choice for every patient seeking a natural result. Many surgeons achieve equally natural results with round implants by carefully selecting the appropriate profile and size. Your surgeon’s recommendation on shape should be driven by your anatomy, not by patient preference alone.

Implant Surface: Smooth vs Textured

Breast implants are available with either a smooth or textured outer surface. Smooth implants move freely within the pocket and have a long safety track record. Textured implants adhere to surrounding tissue, which reduces movement — a relevant consideration for anatomical implants that must not rotate. There has been significant research attention on a rare condition called BIA-ALCL associated with certain textured implants, which has shaped current clinical practice.

Smooth Surface Implants

Smooth implants have an uninterrupted outer shell that allows the implant to move naturally within the pocket. They have been in use for decades and have an established long-term safety record. Because they move freely, they are not appropriate for anatomical shapes — but for round implants, smooth surface is the most commonly selected option globally. Smooth implants are associated with a softer feel and natural movement.

Textured Surface Implants

Textured implants have a roughened outer surface designed to encourage tissue adherence. They were originally developed to reduce capsular contracture rates and to stabilise anatomical implants against rotation. Some research has supported lower capsular contracture rates with textured implants in subglandular placement, though results vary across studies.

A rare condition called Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL) — a type of lymphoma of the immune system, not breast cancer — has been associated specifically with certain macro-textured implant surfaces. The condition is rare, with incidence estimated at between 1 in 3,500 and 1 in 30,000 patients depending on implant type, but it led to the withdrawal of several high-surface-area textured implants from the market and has changed clinical practice in many countries. Your surgeon will discuss current implant options and surface recommendations in the context of your specific case and the implants available in the UAE.

Implant Profile: What It Means and Why It Matters

Implant profile refers to how much forward projection the implant has relative to its base width. Low profile implants are wider and flatter. High profile implants are narrower at the base with more forward projection. Profile selection is driven by your chest width — the goal is to match the implant base width to your natural breast footprint, then choose the profile that achieves the desired projection and size.

Profile is one of the most technically important and least discussed aspects of implant selection among patients. Two implants of the same volume — say, 300cc — can look significantly different depending on their profile. A moderate profile implant at 300cc will be wider and create a subtler, more spreadout increase in volume. A high profile implant at 300cc will project further forward on a narrower base, creating a more noticeable forward projection.

For patients with a narrow chest or small frame, a high profile implant allows meaningful volume increase without the implant base extending beyond the natural breast footprint — which would cause an unnatural appearance. For patients with a wider chest seeking a proportionate result, a lower profile with a wider base may be more anatomically appropriate. Profile is always selected in the context of your measurements, not your desired cup size.

What Your Surgeon Assesses During Consultation

During your consultation, your surgeon will take a series of measurements and make observations that directly inform the implant recommendation. Understanding what they are assessing helps you interpret their recommendations:

Base width of the breast — the horizontal measurement of your natural breast footprint. This sets the maximum appropriate implant base width and is one of the most constraining measurements in implant selection.

Skin elasticity and pinch thickness — how much coverage exists between the skin surface and the chest wall. Thin coverage favours silicone and submuscular placement to minimise visible implant edge and rippling.

Nipple-to-fold distance — the distance between the nipple and the inframammary fold. This influences how the implant will sit and whether a lift component is needed alongside augmentation.

Existing breast volume and symmetry — natural asymmetry is present in virtually all patients and may influence using different implant sizes on each side.

Chest wall shape — a convex or concave chest wall affects how the implant sits and which placement approach provides the most stable, natural result.

Common Misconceptions About Implant Choice

“I want a natural look, so I need anatomical implants.” This is one of the most common misconceptions. Naturalness of result is primarily determined by implant size relative to body frame, profile selection, and surgical technique — not implant shape. Many surgeons achieve highly natural results exclusively with round implants.

“Bigger implants look better.” Implants selected outside the range appropriate for a patient’s chest width and tissue coverage are the most common cause of unsatisfactory results and early revision. The most reliable aesthetic outcomes come from implants sized within the patient’s anatomical parameters.

“Saline is safer than silicone.” Both implant types have extensive safety data and are approved by international regulatory bodies. The rupture detection advantage of saline is real but does not make saline categorically safer. Modern silicone implants are fundamentally different from earlier generation devices. Risk profiles should be discussed with your surgeon in the context of your specific situation.

“I should choose the same size as someone I know.” The same volume implant looks completely different on two patients with different chest widths, existing tissue, and body proportions. Cup size as a target is similarly unreliable — bra sizing is not standardised. Implant selection based on measurements, not cup sizes or comparisons to other patients, produces the most predictable outcomes.

The Bottom Line

Implant selection is a clinical decision shaped by anatomy, not a consumer preference shaped by brand awareness or peer recommendation. The best implant for you is the one your surgeon recommends after a thorough physical assessment — not the one a friend has, not the one most prominently marketed, and not the one that happens to be the lowest cost.

The variables that most reliably predict a satisfying outcome are these: an implant sized within your anatomical parameters, placed by a surgeon with specific breast surgery experience, in a properly accredited facility. Fill type and shape, within the appropriate range for your anatomy, are secondary considerations.
