Filter by:Patients with atrial fibrillation (AF) who have had a prior stroke are at very high risk of recurrent ischemic stroke. About 40% of these strokes are due to large emboli which result in large cerebral vessel occlusion (LVO). This randomized control trial aims to address this unmet need by testing whether use of bilateral carotid filter implants in addition to OAC will reduce the risk of stroke in AF patients with recent (e.g. within 12 months) ischemic stroke vs. only OAC.
The purpose of the study is to evaluate the PrimeTaper's implant survival rate 1 year after permanent restoration (PR). After being identified as being eligible for the study (i.e., via screening and pre-planning surgical visits), subjects will have the PrimeTaper implant placed with a post-op check-up 1-2 weeks later, as well an impression visit in order to develop the permanent restoration. Furthermore, the permanent restoration will be placed no more than 6 months beyond the implant placement visit. After the permanent restoration, there will be follow-up visits at: (i) 6 months, (ii) 1 year, (iii) 2 years, (iv) 3 years, (v) 4 years, and (vi) 5 years.
Study hypothesis: Low level laser (LED) will reduce initial bone resorption and improve primary stability of dental implant. It will also reduces post operative pain compared to patient without treatment Implant osseointegration depends on many factors including biocompatibility of implant materials, design, surface, surgical access, patient conditions, biomechanical status, and lack of primary stability. Several in vivo and in vitro studies showed the healing effect of low level laser therapy (LLLT) on bone by decreasing the initial bone resorption postoperatively and increasing the primary stability of the implant. It has also shown to have an analgesic effect intraorally when used post intraoral surgical procedures. The exact mechanism is unclear despite the fact that many hypothesis has been proposed. In our study, our goal is to present, in a randomized standardized clinical trial, the effect of LLLT on post operative implant stability assessed by resonance frequency analysis (RFA). We will assess the subjective measures of postoperative pain using visual analog scale (VAS).
