OBJECTIVES To identify risk factors for early failure of immediately placed implants in molar regions associated with three bone regenerative techniques. METHODS Ninety-two patients (44 women and 48 men; mean age 50 years, 35 smokers and 57 non-smokers) in need of a single implant crown to replace a molar were included. After placing the implant, patients were randomized to one of three treat...

The maxillary posterior area is the most challenging site for the dental implant. Although the sinus graft is a predictable and successful technique for rehabilitation of atrophic and pneumatized posterior maxilla, when there is severe destruction of alveolar bone, a very long crown length remains challenging after successful dental implants installation with sinus graft. We performed vertical ...

OBJECTIVES The purpose of this study was to compare union rates for isolated subtalar arthrodesis with and without the use of bone grafts or bone graft substitutes. METHODS We retrospectively reviewed 135 subtalar fusions with a mean follow-up of 18 ± 14 months. The standard approach was used for all surgeries. Graft materials included b-tricalcium phosphate, demineralized bone matrix, iliac ...

BONE GRAFTING +*Mak, S Y; *Smith, S D; *Miles, A W +*Centre for Orthopaedic Biomechanics, University of Bath, UK [email protected] INTRODUCTION: Impaction bone grafting (IBG) has been used in revision hip replacement for more than 15 years. The objective is to impact allograft bone chips into the medullary canal to compensate for bone stock loss after failed primary hip replacement. Initial st...

An investigation was conducted to test the feasibility of demineralized bone matrix and cancellous bone chips in a reverse-phase medium carrier (DynaBlast) in concert with an extracellular matrix membrane (DynaMatrix) to provide hard and soft tissue regeneration for the purpose of a ridge preservation procedure. Nine patients requiring extraction of 30 maxillary teeth were grafted with DynaBlas...

LiF, Mg and Ti cubical TLD chips (known as TLD-100) are widely used for dosimetry purposes. The repeatability of TL dosimetry is investigated by exposing them to doses of (81, 162 and 40.5 mGy) with 662keV photons of Cs-137. A group of 40 cubical TLD chips was randomly selected from a batch and the values of Element Correction Coefficient (ECC) were obtained 4 times by irradiating them to doses...

the demand for low fat snacks is increasing. there are different methods to produce low fat fried products. one of these methods is coating. in this study effect of carrageenan, oil temperature and frying time, on oil uptake of fried products (chips and strips) has been evaluated. samples were deep fried in frying oil (palm olein) at 160, 175 and 190 ºc. in order to evaluate the effect of fryin...

This has been done as described by Russe (1960), except that the cavity prepared in both parts of the scaphoid with the aid of a small gouge, is filled with one snugly fitting piece of cancellous bone taken from the ilium, small chips being added when necessary to fill up any remaining gaps. The tightly fitting plug provides immediate immobilisation of the fragments. A plaster splint was used f...
