OBJECTIVES Gingival recession can lead to root exposure and discomfort for patients. There are various techniques for root coverage. The aim of this study was to compare the use of gingival unit graft (palatal graft including the marginal gingiva and papillae) with free gingival graft for treatment of localized gingival recession. MATERIALS AND METHODS In this randomized controlled clinical t...

BACKGROUND Previous experimental studies have been conducted to evaluate the biomechanical effects of posterior cruciate ligament reconstruction; but no consensus has been reached on the preferred method of reconstruction. METHODS The 3D finite element mesh of a knee joint was reconstructed from computed tomography and magnetic resonance images. The ligaments were considered as hyperelastic m...

Guided bone regeneration (GBR) is a reconstructive procedure of alveolar ridge using membranes. This procedure is indicated when there is no sufficient bone for implantation, or in the case of optimal implant installation for esthetic or functional needs. GBR can be performed before implant placement, when there is not enough bone for initial stability of implants and less predictable outcomes ...

background: various materials and techniques have been developed to facilitate bone healing process and reduce its healing period. in recent studies, it is pointed out that, platelet-rich fi brin (prf) which is derived autogenously from the own blood of the individuals, increase regeneration and accelerate the healing of the wound, due to the consisting various growing factors. the aim of the e...

it is difficult to reconstruct an alar defect with cartilage involvement. here in the authors report a case of traumatic alar loss during childhood in which an alar reconstruction was carried out with a composite auricular graft put over the pedicle buccal flap which was rotated and passed through the intraoral side. the lining skin and auricular cartilage for the flap was obtained from the aur...

Surgical treatment for injuries to soft connective tissues are estimated at about 800,000 cases each year in the US. For these surgical procedures, interference screws or suture anchors are needed. Currently, materials used for the devices are non-degradable metals or bioresorbable polymers. However, these materials do lead to complications. Metallic materials suffer from difficulties encounter...

UNLABELLED Micro-invasive bone grafting is to deliver bone graft materials to the desired site through local puncturation and injection. It has many advantages such as little injury, simple procedures and high efficiency of osteogenesis. Limited sources of graft materials and complicated procedures are the main factors affecting the development of the technique. Therefore, to prepare a stable, ...
