PURPOSE The inter-relationships between various implant and bone parameters were evaluated for their influence on the von Mises stress distribution within the mandible using the finite element procedure. The maximum compressive stresses in cancellous and cortical bone were compared to the published stress-strain data to determine bone fracturing status when the maximum (traumatic) loading is ap...

PURPOSE To review published articles dealing with platform switched implants in order to assess survival rates and clarify their influence both on marginal bone loss around the cervical region of the implant and on soft tissue aesthetics. MATERIAL AND METHODS PubMed and GallileUM databases were used to identify any studies or clinical cases involving implant platform switching published betwe...

Objectives. The purpose of this panoramic radiography study was to assess the impact of image magnification on the accuracy of vertical measurements in the posterior mandible. Methods. Six dental implants, inserted in the posterior segments of a resin model, were used as reference objects. Two observers performed implant length measurements using a proprietary viewer with two preset image magni...

Quantitative analysis of histological images of bone-implant samples is a important step in the evaluation of bone-implant integration. However, the quantification is a tedious task when carried out manually in the light microscope. To automatize the quantification, Cuanto, a software for measurements of bone area and estimation of bone-implant contact length in histological images of boneimpla...

PURPOSE To differentiate between the survival and success definitions of functional hydroxyapatite (HA)-coated implant prosthesis. METHODS A total of 248 implants (62 patients), 5-10 years in function, were evaluated. The implant distribution length was 8 mm (6.5%), 10 mm (29.4%), 13 mm (30.2%) and 15 mm (33.9%). The diameter was 3.25 mm (60.1%) and 4 mm (39.9%). Probing depth (PD), gingival ...

BACKGROUND Primary stabilityis not sufficientin less contact area between the implant and bone, the healing process because will be disrupted due to micro-motions and fibrous tissue affects osseointegration. MATERIAL AND METHODS We implemented an in vitro experimental study of total 135 XiVE® implants were inserted in 22.5 bovine cow ribs with bone quality similar to a type IV human bone. Eac...

BACKGROUND Osteointegration of press-fit radial head implants is achieved by limiting micromotion between the stem and bone. Aspects of stem design that contribute to the enhancement of initial stability (ie, stem diameter and surface coating) have been investigated. The importance of total prosthesis length and level of the neck cut has not been examined. METHODS Cadaveric radii were implant...

Introduction: The marginal bone change of 1 year loading was evaluated in the non-microthread collar and platform switching structured INNO® dental implant of which the surface is treated with the RBM sandblasting, hyper-thermal acid etching and alkali solution cleaning process for hydrophilic macroand micro-porosity. Material and Methods: A total of 144 implants were placed in the healed ridge...

PURPOSE The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS A retrospective study of patients rec...
