Donor organ transplantation is currently an essential therapeutic approach to the replacement of a dysfunctional organ as a result of disease, injury or aging in vivo. Recent progress in the area of regenerative therapy has the potential to lead to bioengineered mature organ replacement in the future. In this proof of concept study, we here report a further development in this regard in which a...
By means of histologic and histochemical studies of oxidative enzymes, the pulps of transplanted fully developed maxillary canines have been evaluated after an observation period of 3 to 25 months. No pulp had survived the transplantation trauma, and endodontic treatment of fully developed transplant teeth was considered to be a prerequisite to an optimal clinical result.
OBJECTIVE To volumetrically evaluate soft tissue changes of different ridge preservation techniques compared to spontaneous healing 6 months after tooth extraction. MATERIALS AND METHODS In each of 40 patients, one single-rooted tooth was extracted and four treatment modalities were randomly assigned to the following groups (n = 10 each): A) ß-tricalcium-phosphate-particles with a polylactid ...
BACKGROUND Transplantation of fresh osteochondral allografts (OCAs) is an attractive treatment option for symptomatic articular cartilage lesions in young, healthy patients. Because the lack of OCA bone integration can be a cause of treatment failure, methods for speeding and enhancing OCA bone integration to mitigate this potential complication are highly desirable. PURPOSE To determine if a...
Articular cartilage is composed of chondrocytes and matrix, and it is diffi cult for cartilage to heal after injury. In 1743, Hunter had stated that, “cartilage once destroyed is never recovered.” This was true until 2003, when Koshino and colleagues reported regeneration of degenerated articular cartilage after high tibial valgus osteotomy for medial compartmental osteoarthritis of the knee. I...
