This is not the most ideal for Complete denture but can be managed considerably well compared to the Class III and Class IV types. Residual Ridge morphology is such that it resists horizontal and vertical movement of the denture base. It also comes with Class I maxillomandibular relationship.
We can get good Retention and resistance without much effort in this type of ridge morphology.Ĭlass II: The Residual Ridge Bone height is 16 to 20 mm measured from the least vertical height of the mandible. The Class I morphology is the most suited and most apt morphology of Edentulous ridge for obtaining successful Prosthodontic treatment using Complete Denture prosthesis. It has Class I maxillomandibular relationship.
