Bone Resorption after Use of Silicone Chin Implants, Long-term Follow-up Study with Lateral Chin Radiography

The chin is an extremely relevant anatomic component of facial harmony.1,2 Chin augmentation with the use of implants is a highly effective surgical procedure, with a low rate of complications.1,3 The range of postsurgical patient satisfaction after genioplasty is between 85% and 90%.4 Currently, silicone is the most commonly used material for implants,1 because it causes less adhesion of soft tissue, which makes it easier for the implant to be inserted or removed as necessary.4,5 As with most surgeries, the use of implants may produce complications. There have been reports of a series of possible complications related to the use of implants such as infections, oral incompetence, displacement of the implant, damage of the mental nerve, bone resorption, and so on.1,6 Bone resorption is the most disturbing complication that could occur. This complication occurs because the chin is a very dynamic region, and it is exposed continually to the movements of the lips and mouth.1,7
