Comparison of hand and ultrasonic strokes
Trailer- Lifetime access
What it covers
This lecture provides a detailed comparison between hand instrumentation and ultrasonic scaling, challenging the common misconception that ultrasonics remove more calculus or biofilm per stroke than hand instruments. Instead, emphasis is placed on technique, stroke sequence, and clinical strategy—particularly in managing deep pockets and heavy or tenacious deposits.
Dr. Pattison outlines best practices for initial therapy using scaling and root planing kits, universal curets, and Gracey curets, with guidance on how to tailor your approach during both active and maintenance phases. Limitations of current ultrasonic devices are discussed alongside the specific advantages of manual instruments, especially in terms of control, adaptability, and access to complex anatomy.
Dr. Pattison also introduces Guided Biofilm Therapy (GBT) and devices such as EMS PerioFlow, offering insight into their role in non-surgical periodontal treatment and supportive care.
In particular, this lecture covers the following topics:
- Differences in stroke effectiveness between hand and ultrasonic instruments
- Sequencing instrumentation in deep pockets with heavy calculus
- Selecting the right tools for scaling, root planing, and maintenance
- Benefits and limitations of ultrasonic scalers
- Introduction to Guided Biofilm Therapy and EMS PerioFlow systems
