However as a non-invasive treatment, LIPUS therapy has not ever been reported to be utilized in ABG. We propose a hypothesis is that LIPUS may be an adjunct treatment for osteonecrosis by controlling infection, accelerating bone regeneration and promoting osseointegration after ABG. This hypothesis is based on the following three points: (1) The LIPUS has a bactericidal effect on pathogens rele...

The introduction of percutaneous osseointegration biotechnology in 1979 to head and neck reconstruction permanently revised the long held view that a facial prosthesis was a last resort for the patient and surgeon alike. Since that time, the use of extraoral osseointegration has expanded considerably. The present review of the literature considers indications and methods of care for aspects of ...

Osseointegration of titanium implants is a complex biological process involving interactions between immuno-inflammatory responses, angiogenesis and osteogenesis, all of which are influenced by the physical and chemical characteristics of the implant surface. An implant surface with moderately rough topography and high surface energy influences cellular activities, enhancing peri-implant bone w...

Implant surface topography is a key factor in achieving osseointegration. l-Threonine can be chemically and stably bonded to titanium surfaces by phosphorylation. This study investigated the degree of in vivo osseointegration of an implant with a novel o-phospho-l-threonine (p-Thr)-binding surface. MC3T3-E1 cells were seeded on the p-Thr binding surface and machined surface disks, and initial c...

Mini-implants and miniscrews are commonly used in orthodontics to provide additional temporary intraoral anchorage. Partial osseointegration represents a distinct advantage in orthodontic applications, allowing effective anchorage to be combined with easy insertion and removal. This article reports the histomorphometric findings of the osseointegration of bracket screw bone anchors (BSBAs). In ...

the focus of this paper is to evaluate the influence of mechanical characteristics of the implant on primary stability in different bone types, based on resonance frequency analysis (rfa).a number of 60 nobel biocare replace select tiunit tapered implants of two different lengths (10 mm and 13 mm) and three different widths as 3.4 mm (narrow platform (np)), 4.3 mm (regular platform (rp)) and 5 ...

PURPOSE To test the mechanical stability and histologic osseointegration under load-bearing conditions of 2 different materials, pyrocarbon (Py) and titanium (Ti), in a rabbit model. METHODS Proximal interphalangeal implants (9 Ti, 8 Py) were placed into rabbit knees and the animals were killed after 3 months. Subsidence was assessed by monthly x-rays. Mechanical stability was measured with a...

OBJECTIVES The aim of this pilot study was to evaluate the effects of low intensity pulsed ultrasound (LIPU) on dental implant osseointegration in a rabbit model using mechanical-histomorphometric methods and resonance-frequency analysis (RFA). METHODS Twelve skeletally mature, male New Zealand rabbits (3.4 kg+/-0.5) were included in the study. A total number of 24 implants were placed bilate...
