background: the aim of this in vitro study was to evaluate the effect of shape, diameter and length of implants on their primary stability based on resonance frequency analysis. materials and methods: replace select tapered and branemark mk iii implants were selected. each of these two selected groups was divided into nine subgroups based on the implant length (il) (short, medium and long) and ...

Dental implants made from binary titanium-zirconium (TiZr) alloys have shown promise as a high strength, yet biocompatible alternative to pure titanium, particularly for applications requiring small diameter implants. The aim of this review is to summarize existing literature reporting on the use of binary TiZr alloys for endosseous dental implant applications as tested in vitro, in animals and...

A porous hydroxyapatite/collagen composite (HAp/Col) was developed that consists of hydroxyapatite nanocrystals and atelocollagen. In this study, cylindrical (diameter: 5 mm, height: 3 mm) porous HAp/Col implants with different pore sizes (diameter: 160 or 290 microm) were prepared, and the influences of pore size and implanted volume were evaluated using a rabbit bone defect model. In the impl...

Screw loosening is considered to be a common problem with both screw-retained and cemented implant restorations. A wider abutment platform, as well as using a torque driver to tighten specifically designed screws may help prevent this loosening. However, there has been no clinical study evaluating either of these. To longitudinally compare the frequency of screw loosening in standard diameter, ...

Introdouction: Although highly desirable outcomes and longterm survival of dental implant treatments are well documented, implant failures still occur due to various reasons. Several risk factors may impair implant survival including implant dimensions (length, diameter, and implant design), procedures, local bone density at the implant site, and patient-related risk factors such as age, smokin...

The aim of this study is to illustrate and discuss the fundamentals a well-succeeded minimally invasive technique surgical reintervention for installing implant in reduced area alveolus, affected by agenesis, traumatized an unsuccessful intervention. Materials methods: A 27-year-old patient sought dental care her main cause was great dissatisfaction with aesthetic sequelae region right upper la...

Posterior single-tooth implant restorations are subjected to an increased risk of bending overload. A high incidence of implant fracture has been reported when using a single standard 3.75-mm-diameter implant to support a molar restoration. The purpose of this article is to demonstrate the clinical feasibility of placing two implants to support a molar restoration and to compare this treatment ...

BACKGROUND: The aim of this study was to compare the bone loss pattern and soft tissue healing of immediately versus one-stage loaded 3.0-mm-diameter implants in cases involving a single missing lateral maxillary incisor. METHODS: Sixty patients with a missing lateral incisor in the maxilla were randomized to one of the treatments: 30 patients in the immediate-restoration group and 30 patients ...

AIM The purpose of this study was to evaluate the effect of the implants' diameter on the mechanical function and load-fatigue performance of dental implants. MATERIALS AND METHODS Three groups of implants with different diameters (3.3 mm, 3.75 mm and 5 mm), were tested under static and cyclic compressive loading. A total number of 15 implants for the static test and 112 implants for the cycl...

Implant overdentures are a popular and clinically significant treatment option to present to patients because of the large improvement achieved with a small surgical and financial investment. Narrow diameter overdenture implants, as a result, have gained in popularity in the recent years due to their unique ability to be placed in compromised mandibular alveolar ridges with minimal cost expendi...
