Two-piece zirconia implants in the posterior mandible and maxilla: A cohort study with a follow-up period of 9 years.

Objectives: Long-term follow-up observations of zirconia implants are rare. This study aimed at evaluating the clinical performance of two-piece zirconia implants in the posterior jaws over 9 years.

Materials And Methods: Sixty partially edentulous patients were treated with two-piece zirconia implants.

Cone beam CT in assessment of tibial bone defect healing: an animal study.

Rationale And Objectives: To evaluate cone beam computed tomography (CBCT) for monitoring of tibial bone defect healing in comparison to histopathological findings.

Materials And Methods: Circumscribed tibial bone defects were created in 16 mini-pigs and imaging of the tibia was performed on day 42 using a modern CBCT scanner with flat panel detector (PaX-Duo3D, Vatech, Korea). The extent of osseous consolidation including remaining calcium phosphate granules was measured quantitatively by a CBCT volumetry tool using commercially available software (Osirix Imaging software, Pixmeo, Geneva, Switzerland).

Quantitative assessment of bone defect healing by multidetector CT in a pig model.

Objective: To evaluate multidetector CT volumetry in the assessment of bone defect healing in comparison to histopathological findings in an animal model.

Materials And Methods: In 16 mini-pigs, a circumscribed tibial bone defect was created. Multidetector CT (MDCT) of the tibia was performed on a 64-row scanner 42 days after the operation.
