I suggest that you try Dr. Alonzo Genao, Santiago; email@example.com; 971 3616. I had 5 implants done in July 2003. US $800 per implant; the dentist needed to fit the new crowns on the implants is a different dentist & more $. Genao speaks VG English, very clean & well organzied office, & was very professional. VG follw up. I recommend him w/o hesitation. Good fortune.
