Bone transplantation is often used for the reconstruction of defects. The best results are achieved with autogenous grafts because they induce no immunological reaction, but allogeneic grafts from bone banks are frequently used to provide an adequate volume of bone (Cookson et al 1988). In Germany, about 470 departments using such banks perform about 71 000 autogenous and about 25 000 allogenei...

Reconstruction of large bone defects after resection of malignant musculoskeletal tumors is a significant challenge in orthopedic surgery. Extracorporeal autogenous irradiated bone grafting is a treatment option for bone reconstruction. However, nonunion often occurs because the osteogenic capacity is lost by irradiation. In the present study, we established an autogenous irradiated bone graft ...

In this case report, a mature third mandibular molar was transplanted in the socket of a hopeless first mandibular molar of the same quadrant. A 32-year-old woman was diagnosed with strip perforation of her left first lower molar. Orthograde and retrograde treatments were unsuccessful. The tooth was extracted and replaced by the third molar of the same quadrant. Following transplantation, the t...

Introduction: There are medications capable of affecting bone metabolism and the rate of tooth movement. Among these medications are the immunosuppressants, which act by repressing the action of T lymphocytes, however they can cause bone loss and consequently lead to osteoporosis. Osteoporosis is a common complication following kidney, heart, liver or lung transplantation. The immunosuppressant...

One of the most important purposes of secondary bone grafting of the alveolar cleft is to stabilize the maxillary alveolar arch with completion of the dental arch. We report a case of secondary bone grafting with simultaneous auto-tooth transplantation to the alveolar cleft, using particulate cancellous bone and marrow (PCBM) combined with platelet-rich plasma (PRP), which contains many growth ...

Severely impacted and dilacerated incisors are rarely considered for surgical exposure because they may not respond favorably to orthodontic extrusion. These incisors are often extracted, resulting in the need for tooth replacement; however, prosthetic solutions are limited in growing patients. Transalveolar autotransplantation of an impacted incisor may be the only method to preserve the natur...

This paper describes the autologous transplantation of a mandibular right third molar to replace the residual roots of the second molar in the same quadrant, preserving function and aesthetics. A 5-year clinical and radiographic follow-up was undertaken. After transplantation, the donor tooth received endodontic treatment and placement of calcium hydroxide, which was periodically replaced every...

We previously showed that cartilage tissue can be engineered in vitro with porcine chondrocytes and gelatin/chondoitin-6-sulfate/hyaluronan tri-copolymer which mimic natural cartilage matrix for use as a scaffold. In this animal study, 15 miniature pigs were used in a randomized control study to compare tissue engineering with allogenous chondrocytes, autogenous osteochondral (OC) transplantati...
