I have an overbite and a weak reccessed chin. I would like to know if sliding genioplasty or implant can help improve my profile. I currently have a habit of jutting out my lower jaw when mouth closed, smiling and laughing. I have always been told of having a bigger nose. Will genioplasty help at all. I want to go with the least invasive surgery. I dont have any functional problems with my ovebite and only looking for improving aesthetics.
