I had Dr.Golpa do my 4on4 upper and lowers.,Love em,he did a excellent job,Had upper dentures 2 years ago,i hated them,tried to eat a good steak and had nothing but sores ,then i tried snap'in mini dentures and they weren't any better.My wife Peggy Admann had them done 1 year ago and convinced me on getting this done,i'am so glad that i did it.Thank you Dr.Golpa Dental Implant Center - Las Vegas and all the technicians that helped.
