BACKGROUND This study retrospectively investigated outcomes following dental implantation in patients with special needs who required general anesthesia to enable treatment. METHODS Patients underwent implant treatment under general anesthesia at the Clinic for the Disabled in Seoul National University Dental Hospital between January 2004 and June 2017. The study analyzed medical records and ...

Forty-three patients with severely resorbed maxillae who had been referred for implant treatment were assigned to one of three treatment groups: bone grafting and implant placement (graft group); modified implant placement but no bone grafting (trial group); or optimized complete dentures (no-implant group). Sixteen, 20, and 7 patients, respectively, were assigned to the three groups. At the 1-...

PURPOSE The aim of this study was to analyze and compare the survival rates of endosseous implants placed in the edentulous maxillae of patients in whom bone augmentation was undertaken prior to or in conjunction with implant placement with survival rates in patients who did not undergo bone augmentation. MATERIALS AND METHODS This study included 2 retrospective patient groups: the graft grou...

Over the last years, growing attention has been paid to the several domestic implant systems. This study presents results of a clinical trial of Implantium® implants followed up to 22 months. Two hundred fifty-two Implantium® implants were investigated which were placed in 119 patients between June 2003 and November 2004. The average follow-up period from implant placement was 10. 9months(SD 4....

PURPOSE To compare the 5-year outcomes of the Ahmed FP7 Glaucoma Valve (AGV) (New World Medical, Cucamonga, CA) and the Baerveldt 101-350 Glaucoma Implant (BGI) (Abbott Medical Optics, Abbott Park, IL) for the treatment of refractory glaucoma. DESIGN Multicenter, randomized, controlled clinical trial. PARTICIPANTS A total of 276 patients, including 143 in the AGV group and 133 in the BGI gr...

The corrosion of dental biomaterials is a pertinent clinical issue. In spite of the recent innovative metallurgical and technological advances and remarkable progress in the design and development of surgical and dental materials, failures do occur. The present article describes the problem of corrosion in titanium dental implants. The clinical significance of the dental implant corrosion is hi...

Prosthodontic treatment using dental implants is one of the solutions for partially and completely edentulous patients. The peri-implant area is colonized by a large variety of oral microbial complexes. Various prosthesis may provide means of mechanical attachment to the microflora; this in turn allows their aggregation and colonization. There exists a relationship between the peri-implant micr...

Osseointegrated extra-oral implants have been used effectively as the anchoring points for facial prostheses. The success of the extra-oral implants is dependant upon the continuing health of the bone-implant interface, and although the success rate of extra-oral implants is high there are still recorded failures in all the bones of the face. One of the factors that is believed to influence the...

Cochlear implantation is considered to be a safe and effective treatment for severe to profound sensorineural hearing loss. Device failures are rare. We report the cases of 2 patients--a 44-year-old woman and a 3-year-old boy--with cochlear implants who were referred to our tertiary cochlear implant center for treatment of magnet migration secondary to mild head trauma. The migration had led to...

The purpose of the present study, which used anorganic bovine bone (Bio-Oss) with and without autogenous bone as the augmentation material, was to compare the results of sinus elevation performed without a membrane (control) with the results of sinus elevation performed with either a short-term bioabsorbable membrane (Bio-Gide) or a nonabsorbable membrane (Gore-Tex) with regard to both vital bo...
