INTRODUCTION The objective of the study is to compare the efficacy of fl at insoles, bone spur pads, pre-fabricated orthotics and customised orthotics in reducing plantar contact pressure of subjects with plantar fasciitis. MATERIALS AND METHODS This is a controlled non-blinded comparative study conducted in a tertiary medical institute. Thirty subjects with unilateral plantar fasciitis betwe...

OBJECTIVE To evaluate the rate and degree of osseointegration at chemically modified moderately rough, hydrophilic (SLActive) and moderately rough, hydrophobic (SLA) implant surfaces during early phases of healing in a human model. MATERIAL AND METHODS The devices used for this study of early healing were 4 mm long and 2.8 mm in diameter and had either an SLActive chemically modified or a mod...

Metal plates for internal fixation of fractures have been used for more than 100 years. Although initial shortcomings such as corrosion and insufficient strength have been overcome, more recent designs have not solved all problems. Further research is needed to develop a plate that accelerates fracture healing while not interfering with bone physiology. The introduction of rigid plates had by f...

STATEMENT OF PROBLEM The transition from implant to abutment is solid in 1-piece (1P) and broken in 2-piece (2P) implant designs. This difference may affect occlusal load distribution and marginal bone response. PURPOSE To determine whether 1P and 2P implants with equivalent geometries exhibited stresses and strains differently under applied loading conditions. MATERIALS AND METHODS Design ...

The aim of this experimental study was to evaluate the use of prefabricated autogenous bone grafts as onlay grafts to the mandible. Excess bone of 10 x 12 x 40 mm was produced inside blocks of pyrolyzed bovine bone under a polylactic membrane coverage on the outside of the mandible in 15 adult Göttingen minipigs. After 5 months, this bone was harvested and transferred to the premolar region of ...

Osseointegration of dental implants refers to the process of bone growing right up to the implant surface. No soft tissue connects the bone to the surface of the implant. No scar tissue, cartilage or ligament fibers are present between the bones and implant surface. The direct contact of bone and implant surface can be verified microscopically. When Osseointegration occurs, the implant is tight...

Introduction: This study aims to evaluate the parameters that might have an impact on swallowing performance after a total glossectomy with laryngeal preservation (TGLP). Methods: Among 39 patients who underwent surgery with curative intent for squamous cell carcinoma of the tongue, our retrospective analysis focused on 18 patients treated by TGLP and flap reconstruction. The flap was position...

Infection associated with orthopedic implants often results in bone loss and requires surgical removal of the implant. The aim of this study was to evaluate morphological changes of bone adjacent to a bacteria-colonized implant, with the aim of identifying temporal patterns that are characteristic of infection. In an in vivo study with rats, bone changes were assessed using in vivo microCT at 7...

OBJECTIVE To evaluate the effect of low dose methotrexate alone or in combination with glucocorticoid treatment on titanium implant osseointegration. METHODS Groups of 6-8 adult New Zealand White rabbits were treated for 18 weeks with saline (control), methotrexate, glucocorticoid, or methotrexate plus glucocorticoid. The animals received a titanium implant in the tibia at week 6. Lumbar spin...
