Abstract
This study aimed at evaluating the bacterial colonization in dental implants inserted in the crestal or supracrestal position and correlated it to radiographic bone measurements.
Thirty-five implants with regular platform in nine patients (mean age 62.4±11.2 years) were inserted either at the bone crest level (control group) or at a suprecrestal level (test group). Radiographic examination was performed at baseline (implant installation) and after 6 months. Clinical and microbiological data were collected after 6 months. Digital radiography was used to assess bone remodeling (marginal bone loss and optical alveolar density). Bacterial profile was analyzed by checkerboard DNA–DNA hybridization, including a panel of 40 bacterial species.
After 6 months, there were significantly higher counts of
Significantly higher counts of

Radiographic examination was performed at baseline (implant installation) and after 6 months. Clinical and microbiological data were collected after 6 months. Digital radiography was used to assess bone remodeling (marginal bone loss and optical alveolar density). Bacterial profile was analyzed by checkerboard DNA–DNA hybridization, including a panel of 40 bacterial species.</p></sec><sec id="st3"><title>Results</title><p>After 6 months, there were significantly higher counts of <italic>Actinomyces gerencseriae</italic> (<italic>p=</italic>0.009) and <italic>Streptococcus constellatus</italic> (<italic>p=</italic>0.05) in the test group. No significant differences between test and control groups were observed for marginal bone loss (<italic>p=</italic>0.725) and optical alveolar density (<italic>p=</italic>0.975). Probing depth was similar in both groups.</p></sec><sec id="st4"><title>Conclusion</title><p>Significantly higher counts of <italic>A. gerencseriae</italic> and <italic>S. constellatus</italic> were found in implants placed at the supracrestal level compared to the ones placed at the bone level. No relation was found between the installation level of dental implants and peri-implant bone remodeling.</p></sec></abstract><kwd-group><kwd>dental implants</kwd><kwd>bacteria</kwd><kwd><italic>Actinomyces</italic></kwd><kwd><italic>Streptococcus</italic></kwd><kwd>bone remodeling</kwd></kwd-group></article-meta></front></pmc><affiliations><list><country><li>Brésil</li></country><region><li>État de Rio de Janeiro</li></region><settlement><li>Rio de Janeiro</li></settlement></list><tree><country name="Brésil"><region name="État de Rio de Janeiro"><name sortKey="De Moraes Rego, Mariana Ribeiro" sort="De Moraes Rego, Mariana Ribeiro" uniqKey="De Moraes Rego M" first="Mariana Ribeiro" last="De Moraes Rego">Mariana Ribeiro De Moraes Rego</name></region><name sortKey="De Moraes Telles, Daniel" sort="De Moraes Telles, Daniel" uniqKey="De Moraes Telles D" first="Daniel" last="De Moraes Telles">Daniel De Moraes Telles</name><name sortKey="Figueredo, Carlos Marcelo" sort="Figueredo, Carlos Marcelo" uniqKey="Figueredo C" first="Carlos Marcelo" last="Figueredo">Carlos Marcelo Figueredo</name><name sortKey="Lira Junior, Ronaldo" sort="Lira Junior, Ronaldo" uniqKey="Lira Junior R" first="Ronaldo" last="Lira-Junior">Ronaldo Lira-Junior</name><name sortKey="Lourenco, Eduardo Jose Veras" sort="Lourenco, Eduardo Jose Veras" uniqKey="Lourenco E" first="Eduardo José Veras" last="Lourenço">Eduardo José Veras Lourenço</name><name sortKey="Santiago, Luiz Carlos" sort="Santiago, Luiz Carlos" uniqKey="Santiago L" first="Luiz Carlos" last="Santiago">Luiz Carlos Santiago</name><name sortKey="Torres, Marcelo Ferreira" sort="Torres, Marcelo Ferreira" uniqKey="Torres M" first="Marcelo Ferreira" last="Torres">Marcelo Ferreira Torres</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
