PURPOSE Various bone graft materials have been used for periodontal tissue regeneration. Demineralized freeze-dried bone allograft (DFDBA) is a widely used bone substitute. The current widespread use of DFDBA is based on its potential osteoinductive ability. Due to the lack of verifiable data, the purpose of this study was to assess the osteoinductive activity of different DFDBAs in vitro. ME...

The prerequisites of a successful dental implant are the achievement and maintenance of implant stability. Implant stability may be well-defined as the lack of clinical mobility that is also described as osseo integration. As a mechanical phenomenon, primary implant at placement is associated with quantity and quality of the local bone, the kind of implant method and placement used. Secondary i...

Chronic smoking can lead to failure of Osseo integration due to decrease in local blood flow and failure of cell proliferation by by-products of smoking. This along with immediate failure of a malpositioned implant, devitalization of adjacent tooth necessitating a call for endodontic treatment or the fracture of the adjacent tooth due to malpositioned implant, fracture of the prosthesis due to ...

We carried out a histological study of a proximally hydroxyapatite (HA)-coated femoral component, retrieved after 9.5 years of good function. The HA coating had completely degraded. Bone was in direct contact with the titanium surface in all the areas which had been coated, with no interposing fibrous tissue. There were no signs of particles, third-body wear, adverse tissue reactions or osteoly...

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 ...

The eye is a vital organ and an important component of facial expression. Several ocular and orbital disorders require surgical intervention that may result in ocular defects. Loss of an eye has a crippling effect on the psychology of the patient. Enucleation of the eye is therefore normally followed by fabrication of an ocular prosthesis to improve esthetics. The primary purpose of an ocular p...
