Bone fracture healing is a complex process including inflammation, repair and remodeling. Bone grafts or substitute are widely accepted to treat impaired healing. Newly developed bone substitutes must undergo in vitro and in vivo testing before clinical application. All kinds of intraosseous and heterotopic implant models in small and/ or large animals are used for different bone substitutes. O...

OBJECTIVES The purpose of this preliminary study is to evaluate the effectiveness of a customized, three-dimensional, preformed titanium mesh as a barrier membrane for peri-implant alveolar bone regeneration. MATERIALS AND METHODS Ten patients were recruited for this study. At the time of implant placement, all patients had fenestration or a dehiscence defect around the implant fixture. A mix...

In this study, a new concept of a 3D-printed scaffold was introduced for the accurate placement of an implant and the application of a recombinant human bone morphogenetic protein-2 (rhBMP-2)-loaded bone graft. This preliminary study was conducted using two adult beagles to evaluate the 3D-printed polycaprolactone (PCL)/β-tricalcium phosphate (β-TCP)/bone decellularized extracellular matrix (bd...

Objective: The aim of this study was to assess, through biological analysis, the local effects and osseointegration dental implants incorporating surface micro/nanofeatures compared identical design without treatment. Background: Known impact bone cell behavior, chemical topography modifications target improved long-term success implants. Very few studies assess performance presenting both micr...

The long-term success of arthroplastic joints is dependent on the stabilization of the implant within the skeletal site. Movement of the arthroplastic implant within the bone can stimulate osteolysis, and therefore methods which promote rigid fixation or bone growth are expected to enhance implant stability and the long-term success of joint arthroplasty. In the present study, we used a simple ...

This article addresses diagnostic parameters that should be assessed in the treatment of extraction sockets with dental implant placement by presenting three case reports that emphasize the relevance of the amount of remaining bone walls. Diagnosis was based on the analysis of clinical and radiographic parameters (e.g.: bone defect morphology, remaining bone volume, presence of infections on th...

context a key determinant for clinical success is the diagnosis of the bone density in a potential implant site. the percentage of bone-implant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone. evidence acquisition a number of reports have emphasized the importance of the quality of bone on the survival of dental implants. t...

Implant failure can be because of many reasons, it is difficult to determine the exact cause implant failure, especially when there are factors contributing. This case report reviews in which occurred. A female patient 34 years came with complaint edentulous space region 11. An was placed got exfoliated on 10th day. In this Norris 3.75 /8 6 months back extraction done respect 11 but after bone ...

We report the eventually successful treatment of a huge bone defect and peri-implantitis following reconstruction of a previously failed intra-mobile cylinder implant system (IMZ) implant site using distraction osteogenesis (DO). In the anterior mandible, two IMZ implants failed and surgical debridement was performed in accordance to the patient's needs. Thereafter, mobility and suppuration wer...

This study employed a noncontact resonance frequency (RF) detection technique that was developed by our group to evaluate the interfacial bone in in vitro implant-bone models. Based on our method, the implant-bone structure was excited by the acoustic energy of a loudspeaker, and its vibration response was acquired with a capacitance sensor. The spectral analysis was used to characterize the fi...
