The aim of this work is the microscopic study of the dynamics of the healing of the defect of compact bone tissue after the implantation into its cavity of osteoplastic material «easy-graft CRYSTAL». The experiment was conducted on 24 Wistar rats. In the middle third of the femoral shaft of rats there was reproduced perforated defect in the diameter of 2.5 mm to the medullary canal, which was f...

Introduction: Vocal fold lipoinjection (VFLI) has been used in glottal insufficiency rehabilitation, although with inconsistent results due to unpredictable fat resorption. Recent studies demonstrate that platelet-rich plasma (PRP), obtained from autologous venous blood, increases graft stability, stimulating the proliferation of adipose stem cells (ASC). Objective: The objective of this work i...

Background: Tooth extraction is followed by a resorption of the bone in buccal or facial portion, up to 50% first six months after extraction. Bone loss mainly results from damage periodontal ligament complex. Socket preservation surgical procedure aimed maintain an alveolar ridge extraction, eliminating minimizing need for future augmentation implant-prosthetic rehabilitation. techniques use s...

The use of implants in pediatric cranioplasty is still debatable. Many surgeons prefer to autologous bone grafts than due previous concerns that have a higher risk infection, allergic response, and are not biocompatible as an graft. However, recent studies showed several implant materials similar infection rate following or might be lower compared bone. Moreover, also reported high flap resorpt...

LEARNING OBJECTIVES After reading this article, the participant should be able to: 1. Understand the challenges in restoring volume and structural integrity in rhinoplasty. 2. Identify the appropriate uses of various autografts in aesthetic and reconstructive rhinoplasty (septal cartilage, auricular cartilage, costal cartilage, calvarial and nasal bone, and olecranon process of the ulna). 3. Id...

Animal studies were conducted to evaluate the cell response and chemical potentiality of a synthetic bioactive resorbable graft (SBRG) made of nonceramic cluster particulate of low-temperature HA material. The study evaluated bone-bridging of the SBRG particulates in 1-mm wide implant channels of 5 x 8 mm long roughened titanium interface in 6 dogs and compared results to the same implant chann...

The filling of tissue for facial rejuvenation can be challenging. The aim is to restore harmonious volumetric facial ratios by regaining the contours of cheekbones, drooping jaw lines and nasolobial folds. Adipocyte grafts can return the skin to a state of brightness and to a volume that deteriorates gradually during ageing. To ensure that a tissue graft remains stable, it must be integrated in...

PURPOSE This study investigated the shape of bone grafts and associations with upper limb function over the long term after free vascularized fibular head graft (FVFHG) for reconstruction of the proximal humerus after wide resection for bone sarcoma. METHODS Patients comprised 3 women who had undergone FVFHG at least 5 years previously. Age at surgery was 12 years in 2 cases and 76 years in o...

An operation is described in which a microvascular technique was used to transfer a living fibula, with its vascular pedicle intact, to replace the lower end of the radius after massive resection for giant-cell tumour. Angiography carried out six weeks later showed that the grafted bone was viable. Six months after operation the transplanted fibula showed no osteoporosis or bone resorption and ...
