Usually used for edentulous patients, this type of guide gains its support from the load bearing areas or the divergence of the alveolar ridge.
A bone supported surgical guide is generally used for full-arch edentulous implant cases. This type of guide derives its support from load bearing areas and/or the natural divergence of the alveolar ridge seen in both maxillary and mandibular arches in a corono-apical direction. Bone supported guides are difficult to fabricate and accurately place intraorally due to the extent of flap reflection needed for access, as well as inaccuracies that can result from the digital workflow. Although the difficulties associated with bone supported guides are well reported, they may be mitigated with proper planning, accurate imaging and operator experience.
Bone supported guides are available for most cases. Simply upload your CBCT scan and provide the information on our on line Rx. If the case is to involve immediate prosthetic, ROE can support you with immediate dentures, trough guides, or upgrade to full surgical guide and integrated prosthetics using CHROME GuidedSMILE.
