Evaluation of Implant Abutment Screw Tightening Protocols on Reverse Tightening Values 

The purpose of this in vitro study was to determine the optimal tightening protocol for implant abutment screws

Testing and Calibrating the Mechanical-Type Toggle Torque Wrenches Used in Implant Dentistry: A Dental Technique 

A straightforward, in-office, inexpensive alternative for testing and re-calibrating a toggle torque wrench is described in this article in order to solve common complications in implant-supported crowns. 

Instrument Selection and Application Used to Probe Dental Implants 

A study used to survey clinician's choice of peri-implant instrument selection and the application used to probe dental implants as well as to evaluate peri-implant probing force and pressure applied as compared to that reported in current literature is described in this article. 

Effect of Image Sharpening on Radiographic Image Quality 

This article advised by Dr. Wadhwani studies the effect of Unsharp Masking on digital dental radiographic quality 

Techniques to Optimize Color Esthetics, Bonding, and Peri-Implant Tissue Health with Titanium Implant Abutments 

In this article, a technique involving anodization and simple light reflection is used to improve previous aesthetic issues with titanium. Another technique used to improve the bonding ca[abilities of cement to the abutment is also discussed. 

Screw-Retained Versus Cement-Retained Restorations: Aesthetic Zone Options 

Read about the decision making process of clinicians looking to select the restoration type as related to retention. 

A Customized Healing Abutment for Immediate and delayed Implant Cases

This article serves to describe a technique that enables simple chair-side fabrication of precisely contoured customized healing abutments and exact 3-dimensional intraoral positioning in order to allow for functional and aesthetic implant-supported restorations. 

Accuracy and Reproducibility of Radiographic Images for Assessing Cretal Bone Height of Implants Using the Precision Implant X-ray Locator (PIXRL) Device 

This study used PIXRL to determine if it could produce orthogonal rdiographs of dental implants more accurately that traditional radiologic techniques for assessing crestal bone levels.

In-Vitro Study of the Contamination Remaining on Used Healing Abutments 

In light of a recent investigation into a Las-Vegas dentist who was found to have re-used sterilized healing abutments manufactured for single use, we are sharing our 2016 in-vitro study of the contamination remaining on used healing abutments after cleaning and sterilization.

Laboratory Technique for Coloring Titanium Abutments to Improve Esthetics 

​A common material used for implant abutments onto which prostheses are attached is titanium alloy. One disadvantage to using titanium alloy is that its metallic gray color can show through surrounding tissues or restorative materials. In this article, readily available household items are used to alter the abutment color through anodization.
