“…One study by Bondarenko et al showed that osteoporotic bone has worse osseointegration than healthy bone, and also that the implant can have a significant effect on the osseointegration, or bone-implant-contact [36]. In their study the tantalum implant Trabecular Metal ® and the Trabecular Titanium ® showed better osseointegration than the titanium implants Stiktite ® , titanium with Gription ® coating or Tritanium ® [36].…”

“…It has also been shown that successful osseointegration can occur with bony attachment that involves substantially less than 100% of the bone/implant interface [33,34] and most of the osseointegration occurs around the acetabular rim, and decreases towards the pole [34,35].

Adequate primary stability of the acetabular revision construct is necessary for long-term implant survival. The difference in primary stability between tantalum and titanium components is unclear. Six composite hemipelvises with an acetabular defect were implanted with a tantalum augment and cup, using cement fixation between cup and augment. Relative motion was measured at cup/bone, cup/augment and bone/augment interfaces at three load levels; the results were compared to the relative motion measured at the same interfaces of a titanium cup/augment construct of identical dimensions, also implanted into composite bone. The implants showed little relative motion at all load levels between the augment and cup. At the bone/augment and bone/cup interfaces the titanium implants showed less relative motion than tantalum at 30% load (p < 0.001), but more relative motion at 50% (p = n.s.) and 100% (p < 0001) load. The load did not have a significant effect at the augment/cup interface (p = 0.086); it did have a significant effect on relative motion of both implant materials at bone/cup and bone/augment interfaces (p < 0.001). All interfaces of both constructs displayed relative motion that should permit osseointegration. Tantalum, however, may provide a greater degree of primary stability at higher loads than titanium. The clinical implication is yet to be seen

“…The euthanasia of rats was performed 45 days after surgery by administering a lethal dose of anesthetic (sodium thiopental, 90 mg/kg intramuscularly). This observation period was chosen for the reason that other researchers conducted similar experimental studies on rats in the same period [32], as well as the results of previous study performed by us [28]. Since for this period (45 days) the site of defect is substituted by new formed mature bone.…”

Background: To compare structural features of femoral bone of ovariectomized and non-ovariectomized rats after implantation of porous materials (TANTALUM, CONCELOC, TTM, ATLANT).Methods: Experiments were carried out on 56 white laboratory female rats aged 6-months. Rats were randomly assigned into groups: Sham-operated control group (SH) or ovariectomy group (OVX). Four different commercial implant materials (TTM, CONCELOC, TANTALUM, ATLANT) were placed into the defects (diameter 2.5mm, depth 3.0mm) in the distal metaphysis of femurs. Rats were sacrificed 45-days after surgery. Histological study was performed and the percentage of bone area (BA%) around the implant at a distance of 500μm in the cancellous area was measured.Results: Formation of mature bone tissue of varying degrees around all of the implants was detected. In OVX rats cancellous bone defect zone was characterized by a high density of osteocytes on the surface. In the SH group, no differences in BA% among implant materials were found. In OVX rats the BA% around ATLANT implants was 1.5-time less (p=0.002) than around TANTALUM. The BA% around the rest of the materials was not statistically different.Conclusions: Bone formation around the studied porous titanium and tantalum materials in the osteoporosis model was lower than in normal bone. There were differences in bone formation around the different materials in the osteoporosis model, while in the normal bone model these differences were absent.

Comparative analysis of osseointegration in various types of acetabular implant materials

Abstract: Our study showed that the evaluated implants have good BIC features. Furthermore, based on histomorthometry and histology, Porous tantalum Trabecular Metal (A) and Trabecular Titanium (B) implants exhibit higher BIC with bone tissue.
