Porous tantalum (Ta) is a promising biomaterial and has been applied in orthopedics dentistry for nearly two decades. The high porosity interconnected pore structure of porous Ta promise fine bone ingrowth new formation within the inner space, which further guarantee rapid osteointegration bone–implant stability long term. wettability surface energy that can facilitate adherence, proliferation ...

The majority of acetabular defects can be reconstructed with a hemispherical acetabular component alone. However, severe bone loss encountered at the time of revision acetabular surgery can result in compromised initial fixation leading to component micromotion, failure of bone ingrowth, and mechanical failure. Porous acetabular augments offer a potential solution to enhance initial component f...

OBJECTIVE Since 1993, titanium prostheses have been used in Europe as a biocompatible implant for ossicular reconstruction. More recently, the titanium ossicular prosthesis has become more widely available in the United States as a newer means of surgical restoration of hearing. We will review the hearing results of patients who have undergone tympano-ossiculoplasty using a titanium total ossic...

A topology optimized lumbar interbody fusion cage was made of Ti-Al6-V4 alloy by the rapid prototyping process of selective laser melting (SLM) to reproduce designed microstructure features. Radiographic characterizations and the mechanical properties were investigated to determine how the structural characteristics of the fabricated cage were reproduced from design characteristics using micro-...

For healing of critically sized bone defects, biocompatible and angiogenesis supporting implants are favorable. Murine osteoblasts showed equal proliferation behavior on the polymers poly-ε-caprolactone (PCL) and poly-(3-hydroxybutyrate)/poly-(4-hydroxybutyrate) (P(3HB)/P(4HB)). As vitality was significantly better for PCL, it was chosen as a suitable coating material for further experiments. T...

tooth/implant supported fixed prostheses may present biomechanical design problems, as the implant is rigidly anchored within the alveolus, whereas the tooth is attached by the periodontal ligament to the bone allowing movement. many clinicians prefer tooth/implant supported fixed prosthesis designs with rigid connectors. however, there are some doubts about the effect of attachment placement i...

Biocompatibility and osteoconductivity of porous scaffolds can be improved through coating technique by creating micro- nanostructures on the surfaces. In this study, a biomimetic approach was used to construct bone morphogenetic protein-2 (BMP-2) integrated calcium phosphate (CaP) surface titanium scaffolds. vitro characterizations showed that had mechanical properties comparable those human c...

BACKGROUND Meniscectomy will lead to articular cartilage degeneration in the long term. Therefore, the authors developed an implant to replace the native meniscus. HYPOTHESIS The porous polymer meniscus implant develops into a neomeniscus and protects the cartilage from degeneration. STUDY DESIGN Controlled laboratory study. METHODS In a dog model, a porous polymer scaffold with optimal p...

background & aim: dental implants should be surrounded with at least 1mm bone. assessing ridge width is an important part to achieve this goal. the use of ridge mapping to assess bone levels available avoids some of the problems associated with ct-scanning. the aim of this study was to assess the accuracy of ridge-mapping compared to ct-scan in determination of bony ridge widths. methods & mate...
