How to Select the Right Surgical Guide
Glidewell’s Digital Treatment Planning (DTP) team provides dentists with the full range of guided surgical solutions needed to perform most implant procedures. But how does the doctor determine which surgical guide is best for a particular case? With this simple breakdown of Glidewell’s options for surgical guides, doctors will be able to make more informed decisions.
TOOTH-SUPPORTED
When to Use
Stable remaining teeth
A common misconception is that tooth-supported surgical guides can only be used when a space is surrounded by teeth on the mesial and distal. Glidewell can fabricate tooth-borne guides for cases with a distal or medial extension and include cross-arch supports for added stability, as long as there are enough teeth in the area to support the guide.
The Main Benefit
Stability
When patients have stable teeth to work with, these guides offer the best accuracy for surgical placement.1
TISSUE-SUPPORTED
When to Use
Partially edentulous
Edentulous
Tissue-supported guides sit directly on the mucosa in the absence of teeth. The tissue will support and stabilize the guide throughout the surgery, therefore it is recommended that the tissue be healthy and firm. Varying soft-tissue thicknesses and quality can decrease the stability of the surgical guide.
The Main Benefit
Reduced risk of damage to vital anatomy
Available in multi-level, or “stackable,” options
When patients have good quality mucosa, these guides are an excellent option for reducing the number of surgical steps required to perform the implant procedure. It’s important to note that tissue-borne guides are the least accurate option due to pressure exerted during surgery in combination with the resilient mucosa, which may cause the guide to move.2
BONE-SUPPORTED
When to Use
Partially edentulous
Edentulous
Bone-supported surgical guides are often used for full-arch patients that are being edentulated or are already edentulous. These guides seat directly on the alveolar ridge requiring extensive tissue reflection to properly seat the guide.
The Main Benefit
Added stability in edentulous cases
Available in multi-level, or “stackable,” options
For fully edentulous situations, bone-supported surgical guides offer better stability and accuracy than tissue-supported.3 When used in the multi-level format, these guides come fabricated with a foundation guide that sits on the bone, as well as a bone-reduction guide, osteotomy guide, and other components for immediate loading of a full-arch screw-retained provisional prosthesis when desired.
Guided surgery makes it easier to achieve the ideal implant placement needed for an optimal prosthetic outcome. Through digital treatment planning, a top-down approach can be utilized by first establishing the proper tooth position. Once the restoration is planned, the implant position and abutment choice is much easier to determine. The Glidewell DTP team makes it simple and straightforward to submit and plan a case. Here’s how to get started:
Glidewell also provides ample opportunities to save on costs. To maximize savings and efficiency, doctors can take advantage of the Glidewell HT™ Surgical Bundles. These bundles come with all of the components needed for surgically guided implant placement, healing or temporization, and impressions for one low price. When dentists restore over Glidewell HT Implants through Glidewell, an additional 20% discount will automatically be applied to the restoration. For more information on pricing, as well as downloadable step-by-step clinical guides, protocols and photo templates for each type of surgical guide, doctors can visit
