Screw Versus Mono PDO Smooth Threads: Which One Do You Choose?

By Lauren Niehaus, MSN, CNP

Let’s start from the beginning. PDO smooth threads are composed of polydioxanone suture material, which is often used in cardiac surgeries. Researchers have found that polydioxanone dissolves over a period of three to six months, creating collagen and elastin; therefore rebuilding skin structure. Sounds ideal for the aesthetic industry, right? We can place these threads anywhere in the body that we want to build collagen, without the risk of vascular complications that come along with dermal filler. Smooth threads are great for acne scarring, nasolabial folds, submental skin tightening, the dreaded necklace lines, and so much more. However, when you’re first starting out, the many different thread options can be daunting.

One of the most common questions we receive in our PDO smooth thread courses is “when do I use the screw PDO threads?” Let me break it down for you! Screw PDO threads are my go-to selection for areas of deep deficit. Since the thread is twisted around the needle, rather than looped over, you get more surface area of thread underneath the skin. This creates more collagen and elastin compared to mono smooth threads. I love to use screw threads for nasolabial folds, submental skin tightening, deep lines in the glabella, and umbilicus skin tightening. Screw threads can be slightly more challenging to place than mono smooth threads, however technique for placement remains consistent regardless of the type and size of threads. Screw PDO smooth threads come in 29gx40mm as well as 27gx50mm sizes. Smooth threads are such a quick and easy addition to your practice to help increase your revenue and provide your patients with more comprehensive treatment!
