Chin implant or sliding genioplasty? Please help I'm nervous. (photos)

Iv recently been to a surgeon on the nhs over my side profile and bad anxiety over my side profile the surgeon told me he would put a brace and perform slideing genioplasty but I'd realy just prefare an implant my teeth are straight into had my front four crowned I'm happy with my teeth now finally but I'm wondering if an implant will be enough I realy don't want a big operation I'm a single mum to a toddler and iv read it can be a very complicated surgery will an implant make a difference
