[Dental implant restoration abutment selection].

Hua xi kou qiang yi xue za zhi = Huaxi kouqiang yixue zazhi = West China journal of stomatology, 2017
An increasing number of implant restoration abutment types are produced with the rapid development of dental implantology. Although various abutments can meet different clinical demands, the selection of the appropriate abutment is both difficult and confusing.

Microbiome of titanium and zirconia dental implants abutments

Dental Materials, 2016
This study employed culture-independent molecular techniques to extend the characterization of the microbial diversity of biofilm associated with either titanium or zirconia implant-abutments, including not-yet-cultivated bacteria species, and to identify and quantify species recovered from peri-implantar/periodontal sulci, supragingival biofilm and ...

An investment technique for custom dental implant abutments

The Journal of Prosthetic Dentistry, 2006
Custom implant abutments can be difficult to invest because of the narrow and long screw space that must be completely filled with the investment material. Conventional investing techniques may result in voids in the investment, which may result in the presence of metal in the screw chamber.

Abutment Hammering Tool for Dental Implants

Mechanical Engineering Design Education: Issues and Case Studies, 2001
Abstract One method for installing dental prosthetics uses components fastened with a tapered interference fit. An abutment is fastened into an implant to provide an anchor for the prosthesis. The current method of installation involves hammering with a dental mallet, which provides inconsistent force.

Clinical performance of cantilevered fixed dental prostheses abutments in the shortened dental arch [PDF]

Journal of Dentistry, 2014
This article is part of a randomized clinical trial on different treatments in the shortened dental arch (SDA). It focused on the abutment tooth prognosis with cantilevered fixed dental prostheses (CFDPs).Sixty-two patients with a bilaterally SDA up to the first or second premolar in the mandible or maxilla were evaluated.

Influence of implant/abutment joint designs on abutment screw loosening in a dental implant system

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005
AbstractThe objective of this study was to investigate the influence of implant/abutment joint designs on abutment screw loosening in a dental implant system, using nonlinear dynamic analysis of the finite element method (FEM). This finite element simulation study used two dental implant systems: the Ankylos implant system (Degusa Dental, Hanau, German)

Antibacterial effect of doxycycline-coated dental abutment surfaces

Biomedical Materials, 2015
Biofilm formation on dental abutment may lead to peri-implant mucositis and subsequent peri-implantitis. These cases are clinically treated with antibiotics such as doxycycline (Doxy). Here we used an electrochemical method of cathodic polarization to coat Doxy onto the outer surface of a dental abutment material. The Doxy-coated surface showed a burst

Deformation of Dental Abutment Screw after Tightening and Loosening

Key Engineering Materials, 2007
To evaluate the mechanical deformation phenomena of dental abutment screw after tightening and loosening, five species of abutments were selected (3i-three, Avana- two) respectively by two pieces. The abutment screws were repeatedly tightened and removed 20 times with a digital controller.

INFLUENCE OF ABUTMENT DESIGN ON THE SUCCESS OF DENTAL IMPLANTS

Journal of Biomechanics, 2012
Abutment angulation is one of the numerous biomechanical variables involved in implant dentistry that need scientific evaluation [Saab, 2007]. The aim of the present study was to investigate experimentally and numerically the influence of a fine threadedagainst a roughenedcervical region of immediately loaded dental implants in combination with ...
