Surgeon said sliding genioplasty will give me same results as chin implant?

Without an exam your question cannot be answered.  You will need to see an Oral/Maxillofacial surgeon to see if othognathic surgery, genioplasty or using an implant is best for your specific case. It should be noted that patients with severely weak jaws or abnormally functioning jaws may be better treated with other facial surgery (orthognathic surgery), although a chin augmentation may be an option at a later time. These patients should seek the advice of a plastic surgeon to determine which course is right for them. Here is some information to help you make this decision: Candidates for Chin Augmentation - Patients whose chin profiles are weak but have normally functioning jaws are candidates for Chin Augmentation. Many of these candidates have used injectable fillers in the past to strengthen the protrusion of their chins, but are looking for a permanent solution. If you are one of these patients, then you are a likely candidate for chin augmentation

A chin implant is three-dimensional augmentation of the chin gives not only forward projection, lateral width and small amount of  vertical height.  A chin implant will not help fix the way the teeth come together.  Chin implants are performed under local  anesthesia as an outpatient procedure which takes approximately 30 minutes. A sliding genioplasty is performed by an oral surgeon  under general anesthesia in a hospital with an overnight stay, since the mandible is being cut, slid forward, and plated into the new forward projection.

Hi Julia, If your surgeon says this then most likely they are correct. You can not advance the chin too much. The bone healing would not occur properly. If you need your chin advanced so much you may need jaw surgery instead to begin with.
