Using an extraoral pin to place implants in the anterior edentulous or partially edentulous mandible.
July 1, 2006... When the clinician plans to place an implant in the anterior edentulous or partially edentulous mandible (especially where there is no tooth adjacent to the planned location for the implant), the lack of anatomical references can make proper...

Resorbable screws for fixation of autologous bone grafts.(Clinically Significant ABSTRACTS)
July 1, 2006... The aim of this study was to evaluate the suitability of resorbable screws made of poly (d.l-lactide) acid (PDLLA) for fixation of autologous bone grafts related to graft regeneration and osseointegration of dental implants. In eight...

Performance of six bone collectors designed for dental implant surgery.(Clinically Significant ABSTRACTS)
July 1, 2006... The aim of this study was to perform an in vitro comparison of six bone collectors for harvesting of particulate bone. Four commercially available bone collectors (Frios[R], Osseous Coagulum Trap[R], ACE Autografter[R], Bone Trap[R]) and...

Dental implants placed in expanded narrow edentulous ridges with the Extension Crest device.(Clinically Significant ABSTRACTS)
July 1, 2006... This study has been designed to evaluate the capability of a new surgical device (Extension Crest[R]) to widen narrow edentulous alveolar ridges and to allow a correct placement of endosseous implants in horizontally atrophied sites. ...

Significance of primary stability for osseointegration of dental implants.(Clinically Significant ABSTRACTS)
July 1, 2006... The purpose of this study was to investigate the significance of the initial stability of dental implants for the establishment of osseointegration in an experimental capsule model for bone augmentation. Sixteen male rats were used in the...

Comparison of static and dynamic computer-assisted guidance methods in implantology.(Clinically Significant ABSTRACTS)(Brief article)
July 1, 2006... This study compares computer-assisted fabricated surgical templates as the static method with intro-operative image-guided navigation as the dynamic method for transfer of three-dimensional pre-operative planning. For the static method, the...

Changes in the volume and density of calvarial split bone grafts after alveolar ridge augmentation.(Clinically Significant ABSTRACTS)
July 1, 2006... Resorption after bone grafting often leads to insufficient bone volume and quality, and may subsequently cause dental implant failure. This paper is the first clinical study evaluating bone volume and density changes of calvarial split bone...

Influence of fluoride, hydrogen peroxide and lactic acid on the corrosion resistance of commercially pure titanium.(Clinically Significant ABSTRACTS)
July 1, 2006... Titanium is widely used in dental implantology and orthopedics due to its excellent corrosion resistance and mechanical properties. However, it has been reported that Ti is sensitive to F-, [H.sub.2][O.sub.2], and lactic acid. Atomic force...

Mechanical properties of porous, electrosprayed calcium phosphate coatings.(Clinically Significant ABSTRACTS)
July 1, 2006... Mechanical properties of calcium phosphate coatings (CAP), deposited using the electrostatic spray deposition (ESD) technique, have been characterized using a range of analytical techniques, including tensile testing (ASTM C633), fatigue...

Dental implants placement in conjunction with osteotome sinus floor elevation: a 12-year life-table analysis from a prospective study on 588 ITI implants.(Clinically Significant ABSTRACTS)
July 1, 2006... The purpose of this prospective study was to evaluate the clinical success of placing ITI dental implants in the posterior maxilla using the osteotome technique. All implants were placed following a one-stage protocol (elevating the sinus...

Feasibility and influence of the microgap of two implants placed in a non-submerged procedure: a five-year follow-up clinical trial.(Clinically Significant ABSTRACTS)
July 1, 2006... The aim of this study was to evaluate the feasibility of using a two-piece implant system in a non-submerged procedure and to study the impact of the microgap between the implant and abutment. Sixty edentulous patients (Cawood Class V-VI)...

Computer-guided flapless transmucosal implant placement in the mandible: a new combination of two innovative techniques.(Clinically Significant ABSTRACTS)
July 1, 2006... The objective of this study was to assess whether computer-guided flapless transmucosal implant bed preparation without mucosal punching allows placement of dental implants in edentulous mandibles. Twenty patients with fully edentulous...

Hydroxyapatite film coating by thermally induced liquid-phase deposition method for titanium implants.(Clinically Significant ABSTRACTS)
July 1, 2006... Thermally induced liquid-phase deposition method was employed to produce a thin hydroxyapatite (HA) film on a titanium substrate in a metastable calcium phosphate solution. Titanium foil of 100 x 10 x 0.02 [mm.sup.3] was used as a substrate....

AFM force spectroscopy of the fibrinogen adsorption process onto dental implants.(Clinically Significant ABSTRACTS)
July 1, 2006... Protein binding to implants is governed by the physicochemical properties of the biomaterial surface. The adhesion of a protein onto a solid surface is nonspecific. The aim of this study was to assess the adsorption process of fibrinogen at two...

Antibacterial activity of zinc modified titanium oxide surface.(Clinically Significant ABSTRACTS)
July 1, 2006... Titanium-based implants are successfully used for various biomedical applications. However, in some cases, e.g., in dental implants, failures due to bacterial colonization are reported. Surface modification is a commonly proposed strategy to...
