Clinical Trial: A Randomized Controlled Clinical Trial to Assess Crestal Bone Remodeling of Four Different Implant Designs

U.S., Feb. 12 -- ClinicalTrials.gov registry received information related to the study (NCT06821308) titled 'A Randomized Controlled Clinical Trial to Assess Crestal Bone Remodeling of Four Different Implant Designs' on Feb. 06.

Brief Summary: This randomized controlled trial aimed to assess the effect of the implant neck design (microthreaded vs. non-microthreaded) as well as the type of abutment connection (internal conical vs. external flat-to-flat) on long-term crestal bone remodelling and peri-implant health. Four implants used for a bar-retained maxillary overdenture, were followed over a period of at least 6 years.

Twenty-five patients were treated with a bar-retained maxillary overdenture. Four different implants were placed, with...
