Article Synopsis
- Inserting a titanium implant can change how the bone is stress-loaded, possibly leading to bone loss due to stress-shielding effects.
- A two-dimensional finite element model was created to study the bone-implant interaction and how factors like the bone-implant contact ratio, material properties, and implant roughness influence stress distribution.
- The findings suggest that using implant materials with similar mechanical properties to bone can create a more uniform stress field, potentially reducing negative effects associated with stress-shielding.
The evolution of bone tissue quantity and quality in contact with the surface of orthopedic and dental implants is a strong determinant of the surgical outcome but remains difficult to be assessed quantitatively. The aim of this study was to investigate the performance of a quantitative ultrasound (QUS) method to measure bone-implant interface (BII) properties. A dedicated animal model considering coin-shaped titanium implants with two levels of surface roughness (smooth, S = 0.

The aim of this in vivo preclinical study is to compare the results obtained with these two techniques with the bone-implant contact (BIC) ratio, which is the gold standard to assess dental implant stability.Methods Twenty-two identical dental implants were inserted in the tibia and femur of 12 rabbits, which were sacrificed after different healing durations (0, 4, 8 and 13 weeks).

The quality of the bone-implant interface (BII), resulting from the properties of newly formed bone, determines the implant stability.

This study investigates the spatio-temporal evolution of mineral crystal thickness and plate orientation in newly formed bone around the surface of a metallic implant. Standardized coin-shaped titanium implants designed with a bone chamber were inserted into rabbit tibiae for 7 and 13 weeks.
