Evolution of Adjustable Implants

1. Silicone Gel Implants

Silicone gel implants were the first implants developed. The shape and size has to be very carefully selected and therefore available in a multitude of shapes and sizes.

2. Saline Implants

Empty implant. Fill tube attached.

Implant filled to desired volume.

Fill tube removed.

Tissue Expanders

Tissue expander replaced with breast implant.

Tissue expanders are temporary devices that are used to expand the tissues. For example in, breast reconstruction or severe asymmetry. Tissue expanders are filled after surgery by injecting saline in to the fixed injection dome. The tissue expander is then removed at a second operation and replaced with an implant, gel or saline.

The fill tube can be removed with no saline added or up to 20% saline added.

3. Adjustable Saline Implants 

The adjustable breast implant was developed in 1980 by Dr. Becker. The implant consists of a membrane that is filled with saline via detachable dome. Saline (salt water solution) is added or removed from the implant post-operatively by inserting a thin needle through the skin into the injection dome. Once the patient is satisfied with the size and shape of her breasts, the dome is removed usually three to six months post-operatively. The implant seals at the self-sealing valve. alternativly the injection dome may be exteriorizied and removed one week later.

Single-lumen saline implant (Spectrum)

The adjustable saline implant functions exactly like a normal saline implant, with the added advantage of volume increase and decrease capabilities.

4. Double-lumen saline-gel implant (Becker-Mentor)

Names of the double-lumen saline-gel implant are as follows: Becker 50/50, Becker 25/75 and the Contour Profile Gel (CPG) Becker Implants. The Becker 50/50 is composed of 50% gel in the outer chamber and 50% saline in the inner chamber. The Becker 25/75 is a double-lumen implant with 25% gel in the outer chamber and 75% saline in the inner chamber. The CPG Becker is an anatomically shaped implant with 35% gel in the outer chamber and 65% saline in the inner chamber. These implants are mostly used in reconstruction surgery. However, in selective cases they are useful in treating complications of the breast following breast implant surgery.

Becker Adjustable Breast Implants / Expanders

The Becker is the only gel product that gives you the option of a single or two-stage breast reconstruction. These unique products have an inner lumen containing saline that allows for tissue expansion and an outer lumen of gel, that is designed to provide a softer feeling implant. The remote injection dome makes volume adjustments simple and can easily be removed when expansion is complete.

Adjustable Gel Spectra 

The Spectra adjustable gel implant is a dual-lumen gel implant. However, it has a small inner chamber that can be filled with saline. Gel percentage in the Spectra can range from 100% to 80% of total volume. The implant can be placed in the patient with or without any saline in the inner chamber. If the size is satisfactory, then the fill tube is removed. The implant for all intents and purposes is then a gel filled implant. If, however, further volume is needed, the inner lumen can be filled to the desired volume before the fill tube is removed. If increased projection is desired, the inner lumen can be overfilled. Projection can thus be increased without decreasing the base diameter. The firmer pressure of the overfilled inner chamber aids in projection but without creating undue firmness, due to the presence of the soft gel. The ability to alter implant size and projection at the time of surgery eliminates the need to discard an implant that does not have the correct dimension. In addition, in the event that the desired gel implant is not available, the Spectra adjustable gel implant can be an ideal alternative because of its flexibility.

The adjustable gel implant represents a totally new concept in breast implant design. It was developed by Dr. Becker in 2006. Visit to find out more.

5. Adjustable Gel Implant Spectra

The implant is essentially a gel implant, the inner lumen may be left empty or filled up to 20% for enhanced projection. This is the first adjustable implant that does not require any saline to be added if necessary and has greater volume flexibility.

Another unique feature is that scalloping is not seen on overexpansion.


  • Breast augmentation
    • For post operative volume and projection adjustment.
    • Asymmetry
    • Mild ptosis correction
    • Enhanced projection
  • Augmentation Mastopexy
    • For optimal volume and projection
    • To enhance projection with circum areolar mastopexy
  • Revision Augmentation
    • Where some expansion is required
  • Breast Reconstruction
    • As a second stage replacement following expander removal
    • Immediate one stage reconstruction following skin sparring mastectomy
    • Delayed reconstruction - for enhanced projection
    • Delayed reconstruction where a reduction or augmentation will be done on the opposite breast. Post operative adjustment aids in achievement of asymmetry
    • Revision reconstruction requiring tissue shaping and symmetry
  • Congenital Anamolies
    • Correction of Poland's syndrome where the final implant is required to be a gel
    • Prevention and treatment of Capsular Contraction
    • Replacement of Saline implants or gel implants where rippling has been a problem

Becker Implant Types

Saline and Silicone - Smooth and Textured

Dr. Becker prefers using smooth implants because he feels these give the most natural shape and feel, with less tendency to ripple and less tendency to form fluid collections after surgery.

Dr. Becker's Implants and Breast Reconstruction

These implants were developed by Dr. Becker and act as short-term “tissue expanders” after reconstruction surgery – and as long-term breast implants. The Becker and Becker 50 are double-lumen implants – with the outer lumen being pre-filled with gel while the inner lumen is filled with saline. The Spectrum is a single-lumen implant filled with saline. All three of these implants can be gradually filled for tissue expansion – until the desired volume is obtained.

Implants Overview

  • Implants are available in a single chamber filled with saline or a double lumen containing silicone in the outer chamber and saline in the inner chamber.
  • Implants can be placed under-filled to avoid excess tension on the incision and reduced risk of cutting off the blood supply to the remaining skin.
  • Later adjustability allows you to shape the breast and achieve the size and symmetry you desire.

Adjustable Implants: Gel and Saline


  • Volume can be changed after surgery
  • Patient has input into final size
  • Better able to correct asymmetry
  • Better able to treat complications following previous breast surgery i.e., irregularities in shape, capsular contracture, symmastia (disruption of midline)


  • Injection dome has to be removed (can be buried or externalized)
  • If the injection dome is buried, a second minor procedure, performed under local anasthetic, is necessary to remove the injection dome
  • If the injection dome is exteriorized, no further surgery is necessary for removal.

Adjustable Saline Implants: Smooth vs Textured


  • Thinner Shell
  • More elastic
  • May be filled beyond recommended fill volume
  • Less rippling and scalloping
  • Smooth surgace is less abrasive
  • Easier to use


  • Thicker shell
  • Less elastic
  • Must be filled to optimal volume
  • More rippling and scalloping
  • Rough surface is more abrading
  • More difficult to use

Silicon Gel Implants


  • Smaller incision
  • Lower cost
  • Slightly less incidence of capsular contracture


  • Higher leakage rate
  • Higher incidence of rippling
  • Heavier than gel, therefore preferable placement is behind the muscle to avoid sagging
