Silicone Gel Breast Implants

Abstract

The initial findings show that these implant characteristics are individual factors to be considered separately and are not necessarily correlative. Further study of implants using these and other testing techniques will help clinicians choose between implants.

Covalently Grafted 2-Methacryloyloxyethyl Phosphorylcholine Networks Inhibit Fibrous Capsule Formation around Silicone Breast Implants in a Porcine Model

“…A silicone gel breast implant, the most popular type of breast implant, is composed of a PDMS-based silicone shell encapsulating a silicone-based cohesive gel (Figure S6). 62 We checked if the MPC network could be surface-grafted on the implant shell by the same strategy as for the silicone block. Due to the round shape of the breast implant with a significant projection (2.8 cm), we first grafted the upper, round side of the implant followed by the bottom, flat side by UV illumination.…”

Objective Comparison of Commercially Available Breast Implant Devices

“…A review of the breast implant device literature shows that most is authored by surgeons who have acknowledged financial support from these companies, and is sometimes even co-authored by employees of the company [3][4][5]. As such, they usually focus on only one company's products, they do not offer an unbiased comparison of all available options, and the conclusions must at least be questioned for the presence of bias.…”

Physical Properties of Silicone Gel Breast Implants

“…9 Imaging was used in a morphological analysis comparing shaped and round breast implants manufactured by Allergan, Mentor, and Sientra, and demonstrated changes in upper pole dimension when moving the implants from a horizontal to a vertical orientation. 10 An in vivo magnetic resonance imaging study conducted at least 12 months after implantation of the Allergan Natrelle 410 breast implant in 9 patients found changes in dimension on movement from the supine to prone position, including a mean 29.5% increase in maximum projection. 11…”

“…10,12 Kinney and colleagues used the BTC-2000 method to evaluate the gel material properties of round and anatomic shaped implants. 10 Of the shaped implants, the Allergan Natrelle 410 exhibited less gel elasticity compared with the Sientra implants containing High-Strength Cohesive Plus gel, 10 a finding confirmed in the present study. The round implants tested differed from those evaluated in the current study.…”
