Six kinds of dental implants: Apaceram, Bioceram, Free design blade implant, Shape memory blade implant, Hydroxyapatite-coating blade implant and Vitallium were immersed in three kinds of solutions: Ringer's solution, 1.0% lactate acid solution, and 0.05% HCl solution, for seven days at 37•Ž. Using an inductively coupled plasma emission spectroscope, the solutions were analyzed. The element sol...

The indications for implant dentistry continue to increase, enabling the restoration of partially and totally edentulous patients with greater success and predictability. Recent goals for implant dentistry include simplifying the involved procedures, reducing the duration of therapy for the patient and clinician, and enabling the use of conventional prosthodontic techniques for implant-supporte...

OBJECTIVE Tooth/implant supported fixed prostheses may present biomechanical design problems, as the implant is rigidly anchored within the alveolus, whereas the tooth is attached by the periodontal ligament to the bone allowing movement. Many clinicians prefer tooth/implant supported fixed prosthesis designs with rigid connectors. However, there are some doubts about the effect of attachment p...

The relationship between occlusal overload and peri-implant bone loss remains a controversial topic in implant dentistry. A causal relationship between the incidence of marginal bone loss next to an implant and occlusal overload implies a treatment plan and occlusal scheme would benefit from a force management approach. A MEDLINE-assisted and hand search of peer-reviewed English literature and ...

OBJECTIVE To evaluate the clinical outcomes with the use of a dual-porosity expanded polytetrafluoroethylene implant for midfacial rejuvenation. DESIGN An institutional review board-approved retrospective chart review was conducted of all patients who underwent implantation with the dual-porosity expanded polytetrafluoroethylene implant between 2001 and 2005. RESULTS A total of 170 patients...

CAD/CAM (Computer-aided design/Computer-aided manufacturing) dental implant surgical templates applied in the immediate implant surgery in esthetic area,is beneficial to acquire appropriate three-dimensional position,realize the transformation that from virtual plan to practical surgery, from traditional surgery depended on experience to digital and accurate surgery, improve predictability, acc...

When performing cementless hip arthroplasty, it is critical to achieve firm primary mechanical stability followed by biological fixation. In order to achieve this, it is essential to fully understand characteristics of implant design. In this review, the authors review fixation principles for a variety of implants used for cementless hip replacement and considerations for making an optimal sele...

the effect of inter-implant distance on retention and resistance of implant-tissue-supported overdentures is lacking in the literature. an in vitro study was performed to evaluate this effect for mandibular implant-tissue-supported overdentures retained by two ball attachments.an acrylic cast of an edentulous mandible was fabricated. three pairs of implants were symmetrically placed at both sid...

results the mean distances between the crestal bone and the implant shoulder in group 1 were 1.01, 1.44, and 1.93 mm at the implant placement time, and at the 6 and 12-month postoperative intervals, respectively. in group 2, these distances were 1.35, 1.20, and 1.41 mm, respectively. there were no significant differences in the marginal bone resorption between the two groups (p > 0.05). conclus...
