Immediately after the placement of three en- dosseous implants 4mm direct abutments were tightened on fixtures (fig 16) (Direct Abutment System, Astra TechA
, Molndal, Sweden).
Beaumont of the Mineral Policy Institute (MPI) recently visited Misima to independently assess the problems and reports that the mine operates at one of the central mountains of the small island, with mine pits and waste dumps located at the headway of creeks and rivers providing most of the island population's water supplies.
From 1949 to 1956, the first Russian industrial nuclear facility, Mayak, poured about 7.6 X [10.sup.7] [m.sup.3] of liquid radioactive waste with total activity of 1017 Bq (2.7 X [10.sup.6] Ci) into the Techa

river became heavily contaminated by radioactive waste products from the production of plutonium for nuclear weapons that started at Mayak in 1949.
Four months later, an Astra TechA
implant was placed in the grafted site, surrounded by a thick buccal bony wall, demonstrating excellent primary stability and guaranteeing a better esthetic outcome.
Solid cancer incidence and lowdose-rate radiation exposures in the Techa
River cohort: 1956-2002.
Perhaps unaware of the possible dangers of radioactive wastes, gallons upon gallons of power plant wastes have been dumped directly into the Techa
River that runs 240 kilometers long.
