BACKGROUND The concept of the vestibular implant is primarily to artificially restore the vestibular function in patients with a bilateral vestibular loss (BVL) by providing the central nervous system with motion information using electrical stimulation of the vestibular nerve. Our group initiated human trials about 10 years ago. METHODS Between 2007 and 2013, 11 patients with a BVL received ...

crestal bone loss is a biological complication in implant dentistry. the aim of this study was to compare the effect of progressive and conventional loading on crestal bone height and bone density around single osseointegrated implants in the posterior maxilla by a longitudinal radiographic assessment technique.twenty micro thread implants were placed in 10 patients (two implants per patient). ...

objectives : microbial leakage through the implant-abutment (i-a) interface results in bacterial colonization in two-piece implants. the aim of this study was to compare microleakage rates in three types of replace abutments namely snappy, goldadapt, and customized ceramic using radiotracing. materials and methods: three groups, one for each abutment type, of five implants and one positive and ...

objective: vertical bone loss evaluations in the nobel biocare replace® select tapered tm implant system in the human after one-year loading time. materials and methods: this retrospective cross-sectional study was performed on 31 patients (14 men, 17 women; mean age, 60.39 years) receiving 170 implants (mean, 5.48 for each patient) of groovy and non-groovy designs in the nobel biocare replace®...

UNIOCULAR aphakia is a condition of artificial anisometropia which very often causes great annoyance to the sufferer, who finds the aphakic eye of little use if the other eye is normal, and often complains of lack of binocular function and difficulty in judging distances, especially at close range. If contact lenses have been tried with unsatisfactoryresults, it seems justifiable especially in ...

The use of split-thickness dermal grafts for successful repair of corneal and scleral defects is reported in 10 patients (11 eyes) who had non-infectious, impending, or overt ocular perforation. In all patients, traditional methods of reconstruction were deemed inappropriate or had already failed. Corneo-scleral defects occurred after various operations: pterygium excision, retinal detachment r...

5 Various strategies for ocular drug delivery are considered; from basic formulation techniques for 6 improving availability of drugs; viscosity enhancers and mucoadhesives aid drug retention and 7 penetration enhancers promote drug transport into the eye. The use of drug loaded contact lenses 8 and ocular inserts allows drugs to be better placed where they are needed for more direct 9 delivery...

OBJECTIVE To evaluate the effect of adjunctive intravitreal triamcinolone (IVTA) on intraocular pressure (IOP) in the setting of combined vitrectomy with phacoemulsification. DESIGN Retrospective case series. PARTICIPANTS One hundred thirty-one consecutive eyes undergoing nonemergent vitrectomy with phacoemulsification and IVTA were reviewed and included in the analysis. All 131 eyes receiv...

Vestibular implants are devices designed to rehabilitate patients with a bilateral vestibular loss (BVL). These patients lack a properly functioning vestibulo-ocular reflex (VOR), which impairs gaze stabilization abilities and results in an abnormal loss of visual acuity (VA) in dynamic situations (i.e., severely limiting the patient's ability to read signs or recognize faces while walking). We...
