CAD-CAM custom healing abutments: A dental technique

The Journal of Prosthetic Dentistry
Custom healing abutments are important in establishing optimal esthetics for prosthesis-driven, implant-supported restorations. This report demonstrates a technique for constructing a custom healing abutment with computer-aided design and computer-aided manufacturing to save chairside time and provide predictable results.

In Vitro Evaluation of the Removal Force of Abutments in Frictional Dental Implants

Journal of Oral Implantology, 2011
The objective of the present work was to determine some force parameters for removal of an abutment from a dental implant in a frictional system (locking taper, 1.23 degrees). Ten implants of the same length (11 mm) and different diameters were selected, along with 10 straight abutments (13 mm length) with different diameters.

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 ...

A custom auricular implant healing abutment: A dental technique

The Journal of Prosthetic Dentistry
Skin overgrowth is a complication that hinders bone-anchored prosthetic ear rehabilitation. In order to accurately transfer the healing skin for prosthetic reconstruction, this article introduces a custom-made autopolymerizing acrylic resin auricular cap (button) through indirect pick up of the metal housing.

Probabilistic analysis of preload in the abutment screw of a dental implant complex

The Journal of Prosthetic Dentistry, 2008
Screw loosening is a problem for a percentage of implants. A probabilistic analysis to determine the cumulative probability distribution of the preload, the probability of obtaining an optimal preload, and the probabilistic sensitivities identifying important variables is lacking.The purpose of this study was to examine the inherent variability of ...

Micromotion and dynamic fatigue properties of the dental implant–abutment interface

The Journal of Prosthetic Dentistry, 2001
Clinical loading may result in micromotion and metal fatigue in apparently stable implant screw joints. This micromotion may contribute to tissue inflammation and prosthesis failure.This study investigated dental implant screw joint micromotion and dynamic fatigue as a function of varied preload torque applied to abutment screws when tested under ...

Miniaturized Electromagnetic Device Abutment Improves Stability of the Dental Implants

Journal of Craniofacial Surgery, 2019
Background: The overall success and predictability of dental implant treatment hinge on the primary stability, direct bone-to implant contact formation, and quantity and/or quality of residual bone. Pulsed electromagnetic field has been reported to increase bone regeneration in various clinical situations.

Root Fracture of Abutment Teeth for Partial Removable Dental Prostheses

The International Journal of Prosthodontics, 2016
Root fracture is a common and serious cause of abutment tooth loss. No studies to date have comprehensively assessed the individual contributions of the factors that increase stress on abutment teeth. The purpose of this study was to analyze the stress distribution in abutment teeth based on a three-dimensional finite element model and to analyze the ...

Characterization of Micro-Machining of Dental Screws and Abutments

2017
In today’s society, dental implants are a growing solution for dental care. However, most dental components are very expensive when imported, and are purchased at premium costs solely from a few international companies. It is estimated that the current market price of dental implants is as much as one thousand times the material cost.

Retrieving a “frozen” over‐torqued altered dental implant healing abutment: A dental technique

Journal of Prosthodontics
AbstractThis report describes a method for retrieval of an over‐torqued and altered dental healing abutment using a conservative approach with readily available armamentarium. The previously unretrievable prosthetic component had been modified to support an implant crown prosthesis which required replacement.
