In recent years, there has been a growing demand for aesthetic orthodontic treatments, leading to the rise in popularity of clear aligners. These aligners offer a discreet and convenient alternative to traditional braces, but certain tooth movements, such as extrusion, remain challenging. Extrusion requires precise and stable force application, which clear aligners alone may struggle to achieve. To address this, attachments-small, tooth-colored composite resin pieces-are strategically placed on teeth to enhance aligner grip and improve force transmission. Various attachment designs exist, each with unique benefits for specific movements like extrusion. This systematic review aims to analyze the efficacy of different attachment designs in generating extrusive forces. By examining studies such as randomized controlled trials and FEM studies, the review seeks to provide evidence-based guidance for orthodontists. The goal is to enhance treatment outcomes, improve patient satisfaction, and offer clinicians valuable insights into optimizing clear aligner therapy through effective attachment selection.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.?

We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
