OBJECTIVES Implant design features such as macro- and micro-design may influence overall implant success. Limited information is currently available. Therefore, it is the purpose of this paper to examine these factors such as thread pitch, thread geometry, helix angle, thread depth and width as well as implant crestal module may affect implant stability. SEARCH STRATEGY A literature search wa...

Loss of fixation between bone and implant surface is one of the main treatment problems in total hip arthroplasty. It might lead to implant instability, bone loss and treatment failure resulting in revision surgery. Surface modification is a method for improving bone response to implant and increasing implant osseointegration. However, the currently applied modifications such as hydroxyapatite ...

BACKGROUND The purpose of this study was to compare a parallel wall design implant to a tapered apex design implant when placed in the posterior maxilla using two different surgical protocols. METHODS Twenty-seven patients (30 implants) were divided into three groups. All implants were 4 mm wide in diameter and 8 mm long. Group A received 10 tapered implants (OSPTX) (Astra Tech OsseoSpeed TX™...

BACKGROUND Insufficient bone volume often hamper placement of dental implants in the posterior maxilla. PURPOSE The aim of the present clinical study was to evaluate retrospectively the clinical outcome of implant placement in the resorbed posterior maxilla using an osteotome technique without adding any grafting material. MATERIALS AND METHODS Twenty patients with 5 to 9 mm of residual alv...

PURPOSE This study investigated the influence of bone quality and surgical technique on the implant stability quotient (ISQ) value. In addition, the influence of interfacial bone quality, directly surrounding the implant fixture, on the resonance frequency of the structure was also evaluated by the finite element analysis. MATERIALS AND METHODS Two different types of bone (type 1 and type 2) ...

The osseointegration and long-term success of bone-interfacing implants are dependent on mechanical stability of the implant relative to host bone during the early healing period. The geometric design of an implant surface may play an important role in affecting early implant stabilization, possibly by influencing tissue healing dynamics. In this study, we compared the early tissue healing resp...

Implant dentistry has come a long way since 1981, with great improvements made to achieve primary implant stability and improve bone-to-implant contact. The focus has since shifted toward creating an esthetic restoration that is indistinguishable from natural teeth and is stable over time. This paper proposes a management triad that enhances soft tissue thickness around implant-supported restor...

To investigate whether there are differences in patients' denture satisfaction when an implant placed in the midline of the edentulous mandible is loaded either immediately or three months later, after second-stage surgery. One hundred and fifty-eight edentulous patients received a single implant in the midline of the mandible. After randomisation, it was loaded either immediately after implant...

This document contains the supplementary figures and details on the patient cohort and on the stability of the implant in the first module of the multicentre clinical trial using the subretinal implant Alpha IMS (Retina Implant AG, Reutlingen) that are described in the manuscript by K Stingl et al.: Artificial Vision with Wirelessly Powered Subretinal Electronic Implant Alpha IMS. The electroni...
