Abstract
Patient: A 71-year-old female complained of masticatory disturbance resulting from the unconformity of her upper and lower removable partial dentures (RPDs). Non-vertical stop occlusion was observed, and her RPDs were functionally unstable because of the deflected mandibular position including the low occlusal vertical dimension and the inadequate design of the RPDs. The mandibular position was recovered using the treatment RPDs, and de.nitive RPDs were set after reassessment of her oral condition
s. Discussion: The proper mandibular position, the proper distribution of occlusal force on her occlusal arches by the relevant occlusal contacts and the rigid support design as a result of the proper supporting and bracing elements of the RPDs were fundamental for RPD stability in a case of non-vertical stop occlusion.
Conclusion: This case with non-vertical stop occlusion was successfully rehabilitated using the RPDs supplying relevant occlusal force distribution and function stability.
