Scientific reports·2025

A new micro-computed tomography (micro-CT) method accurately calculates the potential bone/implant contact area (p-BICA) for dental implants. This reliable technique allows for predictable industrial design and comparison of implant properties.

Area of Science:

  • Biomaterials Science
  • Dental Implantology
  • Medical Imaging

Background:

  • Dental implant success is influenced by bone-to-implant contact.
  • Quantifying the potential bone/implant contact area (p-BICA) is crucial for predicting osseointegration.
  • Existing methods may lack precision or accessibility for standardized evaluation.

Purpose of the Study:

  • To present and validate a micro-computed tomography (micro-CT) based method for calculating the p-BICA of dental implants.
  • To assess the stability and repeatability of the developed measurement technique.
  • To establish a standardized approach for evaluating implant surface characteristics relevant to osseointegration.

Main Methods:

  • Utilized micro-computed tomography (micro-CT) for three-dimensional imaging of seven commercial dental implant types.

  • Employed computer-based data processing to determine the p-BICA for each implant.
  • Repeated measurements twice to evaluate the method's stability and repeatability.

    • Main Results:

    • The micro-CT method provided precise p-BICA values for all tested implants, ranging from 118 mm² (XiVE S CELLplus) to 199 mm² (Straumann Solid screw).
    • The measurement procedure demonstrated high stability and reproducibility across repeated trials.
    • Significant variations in p-BICA were observed among different implant designs.

    Conclusions:

    • The micro-CT based method offers a precise and reproducible means to determine the p-BICA of dental implants.
    • The calculated p-BICA is influenced by the implant's micro- and macrostructure.
    • This method facilitates predictable industrial design and allows for objective comparison of dental implant properties, irrespective of proprietary design details.
