Indirect orthodontic bonding--a modified technique for improved efficiency and precision.

Introduction: The indirect bonding technique optimizes fixed appliance installation at the orthodontic office, ensuring precise bracket positioning, among other advantages. In this laboratory clinical phase, material and methods employed in creating the transfer tray are decisive to accuracy.

Objective: This article describes a simple, efficient and reproducible indirect bonding technique that allows the procedure to be carried out successfully.

New methodology for evaluating osteoclastic activity induced by orthodontic load.

Orthodontic tooth movement (OTM) is a dynamic process of bone modeling involving osteoclast-driven resorption on the compression side. Consequently, to estimate the influence of various situations on tooth movement, experimental studies need to analyze this cell. Objectives The aim of this study was to test and validate a new method for evaluating osteoclastic activity stimulated by mechanical loading based on the fractal analysis of the periodontal ligament (PDL)-bone interface.
