Marginal bone response of submerged and non-submerged osteoconductive alkali-etched implants in thick and thin biotypes: A 2-year clinical follow-up study.

Purpose: This follow-up study evaluated the implant success rate and marginal bone response of submerged and non-submerged osteoconductive two-piece implants with a moderately rough implant neck in thick and thin gingival biotypes.

Materials And Methods: The stability of the hard tissue surrounding the implants was evaluated, based on clinical and radiographic examinations performed after implant placement and every follow-up thereafter. The clinical data were processed via linear mixed-effects model statistics at the patient level.

18 months of experiences with the biotitanium replacement (Implaspin) used in treatment of degenerative lumbar spine diseases.

Between 2007-2008 forty two patients neurosurgery department of the KNTB (Regional Hospital of T. Bat'a) Zlin underwent surgery using the bioactive replacement Implaspin. The group of 21 patient of the total of number of 42 patients was operated first time for diagnosis degenerative instability or spondylolisthesis gr I-II.

Bioactive titan cage Implaspin in treatment of degenerative disease of the cervcal spine--the results from 2007 till 2008.

The authors present results of surgical treatment of cervical spine degenerative disease via Implaspin biotitanium replacement. Surgery was indicated for a group of 24 patients with symptoms of cervical spondylogenic myelopathy or the irritation decay root syndrome non-reacting to conservative treatment. Pre-surgery X-ray and MRI examinations showed spinal canal stenosis caused by the intervertebral disk osteochondrosis combined with prolapse or dorsal osteophytes.

Secondary stability assessment of titanium implants with an alkali-etched surface: a resonance frequency analysis study in beagle dogs.

Purpose: This study was carried out to quantify the effect of an alkali-modified surface on implant stability during healing using an animal model.

Materials And Methods: A total of 24 screw-shaped, self-tapping, commercially pure titanium dental implants, divided into a test group (implants with an alkali-modified surface or "biosurface") and a control group (implants with a turned, machined surface) were inserted without pretapping in the tibiae of 3 beagle dogs. The resonance frequency analysis method was used to measure the implant stability quotient (ISQ) 0, 1, 3, 9, and 12 weeks after implantation.

[Verification of a surgical technique using a new biotitanium cage in degenerative diseases of the lumbar spine--experimental study].

Purpose Of The Study: Authors performed experimental PLIF operations on cadavers to verify appropriate shape and size of cage made from bioactive titan material. The approach for application into intervertebral space of the lumbar spine and appearance on X-ray and CT scans was also investigated.

Material: In experiment on cadavers five implantations of interbody cages were performed, two of them in interbody space L3/L4 and three of them in L4/L5.
