I want to have chin implant too. Mind telling me more about the bone erosion? I remember Cupid&Star did mentioned once about the bone erosion possibilities with Silicon chin implant.
Read This. Hope its useful.
Because the chin implant is placed in a dynamic region, it is subjected to micromotion due to oral and labial movements for speaking, expression, and deglutition. This may lead to bony changes under the implant. Erosion is classified as type I if it is up to 3 mm, type II if it is 3-5 mm, or type III if it is more than 5 mm. Bony absorption under the implant is perhaps the most dreaded complication following alloplastic chin augmentation and is a common complication. This has been described with silicone implants and the harder alloplasts (eg, Medpor). By avoiding the subperiosteal plane, some bony absorption can be prevented. Good positioning also may prevent this complication. Larger implants have also been associated with erosion. Erosion has been reported as early as a few months after augmentation.
But mY ps said, whats make the difference between the implant material is,.. Ex. like medpor,.. allowed for soft tissue and bony ingrowth to the pores of implant,.. so make more stable than silicone and less grinding with chin bone when you talking, eat, laughing, etc which is cause the bone erosion greater.
