  1. 1. Reliability and precision of root length measurements in cone beam CT images: a study of adolescents

    University essay from Malmö universitet/Odontologiska fakulteten

    Author : Alexander Coholic; Fanny Hellberg; [2019]
    Keywords : CBCT; Reliability; Precision; Root length measurement;

    Abstract : Bakgrund: Under en ortodontisk behandling med fast apparatur finns det en risk för att tänderna drabbas av rotresorption. Rotresorptioner kan mätas med hjälp av Cone Beam Computed Tomography (CBCT). Mätresultatet kan dock variera mellan olika observatörer och mätfel kan uppstå vilket påverkar metodens tillförlitlighet.

    Abstract : Sammanfattning Syfte Syftet med projektet var att undersöka tillförlitligheten i mätningar av marginala bennivån, i anslutning till implantat, i röntgenbilder tagna med CBCT, genom att använda 2 observatörer. Material & metod Röntgenbilder från CBCT undersökningar utförda på 37 patienter 2,5– 7 år efter implantatbehandling bedömdes av två observatörer avseende den marginala bennivån. READ MORE

  5. 5. Impact of peri-implant buccal bone thickness, implant fixture diameter, abutment and/or prosthetic reconstruction material on the accuracy of Cone Beam Computed Tomography to assess peri-implant buccal bone level: an in vitro study in pig jaw

    University essay from Malmö universitet/Odontologiska fakulteten

    Author : Salman Ahmad; [2018]
    Keywords : ;

    Abstract : Abstract Aim: To evaluate the impact of peri-implant buccal bone thickness, implant fixture diameter, abutment material (Titanium Ti, Zirconium Zr) and/or prosthetic reconstruction material (metal ceramic vs ceramic) on the accuracy of Cone Beam Computed Tomography (CBCT) to assess peri-implant buccal bone level. Materials and methods: Titanium implants were inserted into 36 blocks of pig mandible in a way to create variable buccal bone thicknesses groups, each group with 12 blocks; group 1 (0. READ MORE
