A Mandibular Removable Partial Denture with flexible framework was made for a 42 year old female patient. Missing teeth are 36, 37, 38, 46 and 48 FDI Two-Digit Notation, lower left first molar, second molar and third molar, lower right first molar and third molar.

5 Unit Porcelain Fused to Metal Fixed Partial Denture.
A Maxillary / Upper Removable Partial Denture was made for a 75 year old, male patient. Remaining teeth are 14, 15, 17 FDI Two-Digit Notation, upper right first premolar, upper right second first premolar and upper right second molar.
Upper Removable Partial Denture Occlusal
Occlusal factors which are considered in Denture Construction:
Muscles
These are the drivers of the system and are what put it all in the motion. They include muscles of mastication and posture, and their adaptability.
Skeleton
Genetic and functional demands strongly affect occlusion. Consider deep Class II malocclusions with exaggerated Curves of Wilson and Curves of Spee.
Joints
Unique in that they function as a pair and dislocate during normal function. Capable of significant remodelling and susceptilble to damage.
Dentition
Dominates the entire system by establishing maximum intercuspation. Establishing a centric occlusion with no sloping interferences is the basis for long term stability.
Patient
Psychological aspects of patient’s expectations and perceptions will either nullify or exaggerate any of the other factors.
Rebasing refers to a process of refitting of a denture by the replacement of the entire denture base with new material without changing the occlusal relations of the teeth. In a rebase procedure, denture teeth may sometimes need to be replaced.
Old Upper Complete Denture Indicated for Rebasing
Dentures are relined for the following reasons:
- to treat pressure spots
- to improve fit, re-adapt the denture
- to cushion sharp-edged alveolar processes
- to support the healing process in dental implantology
