Characterization of Extraction Sockets by Indirect Digital Root Analysis
The International Journal of Periodontics & Restorative Dentistry
|February 2, 2021
Summary
This study digitally analyzed extraction socket dimensions using 420 teeth. Findings provide crucial data for dental procedures like socket grafting and implant placement.
Area of Science:
- Dentistry
- Oral Surgery
- Digital Imaging
Background:
- Accurate characterization of extraction sockets is essential for predictable clinical outcomes.
- Indirect digital root analysis offers a novel approach to quantify socket morphology.
Purpose of the Study:
- To digitally characterize human extraction sockets by estimating socket volume and orifice dimensions.
- To provide quantitative data for dental clinicians and product development.
Main Methods:
- 420 permanent teeth (excluding third molars) were scanned to generate STL files.
- Digital analysis was performed 2.0 mm apical to the cementoenamel junction (CEJ).
- Socket volume, orifice surface area, and linear dimensions (buccolingual, mesiodistal) were computed.
Main Results:
- Maxillary first molars had the largest mean root volume (0.451 cc).
- Mandibular first molars had the largest socket orifice area (78.56 mm²).
- Specific teeth exhibited distinct orifice dimensions, with maxillary first molars largest buccolingually and mandibular first molars largest mesiodistally.
Conclusions:
- Digital root analysis provides precise measurements of extraction socket morphology.
- These data aid in planning socket preservation, implant provisionalization, and product design.
- Understanding tooth-specific socket dimensions optimizes site management strategies.

The distribution law or Nernst's distribution law is the law that governs the distribution of a solute between two immiscible solvents. This law, also known as the partition law, states that if a solute is added to the mixture of two immiscible solvents at a constant temperature, the solute is distributed between the two solvents in such a way that the ratio of solute concentrations in the solvents remains constant at equilibrium.

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

01:19Plotting and Calibrating the Root Locus
263
Root loci often diverge as system poles shift from the real axis to the complex plane. Key points in this transition are the breakaway and break-in points, indicating where the root locus leaves and reenters the real axis. The branches of the root locus form an angle of 180/n degrees with the real axis, where n is the number of branches at a breakaway or break-in point.
The maximum gain occurs at the breakaway points between open-loop poles on the real axis, while the minimum gain is...

The root locus method is an invaluable tool for analyzing higher-order systems without needing to factor the denominator of the transfer function. A pole of the system is identified when the characteristic polynomial in the transfer function's denominator equals zero.
To determine if a point lies on the root locus, the criterion involves the sum of angles contributed by all poles and zeros to that point. Specifically, this sum must be an odd multiple of 180 degrees. The gain at any point on...
