Guidelines and Strategies for Safe Computer Charting

Guidelines and Strategies for Safe Computer Charting

The guidelines and strategies provided by the American Nurses Association (ANA) and the Canadian Nurses Association (CNA) offer essential principles for ensuring safe and secure computer charting systems in healthcare settings. Let's break down each recommendation:

Masking and Demasking Agents

Masking and Demasking Agents

EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...

Area of Science:

Dentistry
Oral Surgery
Implantology

Background:

The socket-shield procedure is crucial for preserving soft and hard tissues during immediate implant placement.
The Selective Preservation of Tooth (SPOT) protocol provides a tooth-guided method for socket-shield preparation in both anterior and posterior teeth.

Purpose of the Study:

To present a fully guided protocol for the SPOT procedure and immediate implant placement in single-rooted teeth.
To detail the use of osseodensification burs for simultaneous apex removal, shield preparation, and implant site preparation.

Main Methods:

Utilized a guided SPOT protocol with osseodensification burs for sequential clockwise and counterclockwise operations.
Employed two static surgical guides for precise trajectories in apex removal, shield preparation, and implant site preparation.
Incorporated compaction-autografting of bone and dentin into the alveolus for enhanced primary stability.

Main Results:

Achieved improved drilling accuracy and reproducibility through guided procedures.
Demonstrated reduced chairside time due to the streamlined, guided protocol.
Facilitated prefabrication of provisional restorations or custom healing abutments.

Conclusions:

The guided SPOT protocol offers a reproducible and efficient method for immediate implant placement with socket-shield preservation.
This technique enhances primary implant stability and promotes early healing by utilizing autografted bone and dentin.
The protocol streamlines the surgical process, improving outcomes for single-rooted tooth immediate implant procedures.
