Area of Science:

  • Dental Implantology
  • Biomaterials Science
  • Prosthodontics

Background:

  • Single tooth implants are a common solution for missing teeth.
  • Evaluating new implant designs is crucial for improving patient outcomes.
  • The Astra Tech implant features a microthreaded conical neck and TiO blast surface.

Purpose of the Study:

  • To evaluate the clinical and radiographic success of a new Astra Tech single tooth implant design.
  • To assess bone level changes and soft tissue health around the implants over two years.
  • To determine the incidence of complications such as abutment screw loosening or implant failure.

Main Methods:

  • Fifteen patients received Astra Tech implants in the maxillary anterior region.
  • Implants were placed and submerged for six months before restoration.

  • Clinical and radiographic assessments were performed at crown insertion, one year, and two years.

    • Main Results:

    • All implants integrated successfully, with no losses reported.
    • No abutment screw loosening or soft tissue problems were observed.
    • Mean bone levels remained stable, showing no statistically significant changes over two years.

    Conclusions:

    • The Astra Tech single tooth implant design demonstrated high clinical and radiographic success.
    • Bone stability and maintenance of gingival health were favorable.
    • The implant's performance is comparable to other systems with high long-term success rates.
