Jaw surgery after camouflage treatment?

Is it possible to get a djs after you have braces. My camouflage treatment fixed my open bite. But I feel like my skeletal problem is still there. The jaw surgery id like to do, is maxillary impaction to fix my gummy smile and mandible advancement with counterclockwise rotation to flatten my steep occlusional plane. Also my bite is pretty good now. Do I necessarily need to do decompensate my bite ?
