U. Karlsson et al., SINGLE-TOOTH REPLACEMENT BY OSSEOINTEGRATED ASTRA TECH DENTAL IMPLANTS - A 2-YEAR REPORT, The International journal of prosthodontics, 10(4), 1997, pp. 318-324
This study presents the outcome of single-tooth restorations supported
by Astra Tech single-tooth implants followed for 2 years. Forty-seven
implants were placed in the same number of patients. Forty-three pati
ents attended the second recall visit, and none of the evaluated impla
nts have been removed. The mean marginal bone loss after 2 years of se
rvice was 0.31 (SD = 0.48) mm. Overall, few complications were recorde
d during the 2-year period, the most frequent of which were loose crow
ns (7).
