The clasp features a mesial lingual undercut for retention and a short bracing or reciprocating arm; In addition, retention is adjustable. The diagnostic cast was surveyed to ensure the adequacy.

The present case report describes the modified design of major connectors used in maxillary and mandibular removable partial dentures for the management of. This case report presents rehabilitation of a partially edentulous mandibular arch opposing completely edentulous maxillary arch using digital technology and casting using. This clinical report describes the treatment of a patient with an anterior maxillary edentulous area using a dual path rpd.
Due to instability of his remaining maxillary teeth stemming from caries and periodontal disease, it was agreed that extracted teeth would be cosmetically replaced with an immediate interim rpd until the.
As was stated in chapter 7, retention is accomplished by placement of mechanical retaining elements (clasps) on the abutment. This program of instruction reviews the basic. The objective is to design and rpd which effectively retains the obturator prosthesis without subjecting the abutment teeth to pathologic stress which may limit their lifespan. Centric occlusion is often distant from centric relation in partially edentulous patient because of unfavorable jaw relations,.
Other components are presented in. Digital the design and fabrication of maxillary removable partial denture (rpd) frameworks is now a reality. For the most part, although far more protective to abutment teeth, class ii lever rpds are limited in. To prevent displacement of rpd away from oral tissues and rotational movements, retention is obtained by direct and indirect retainers.

### Design of maxillary and mandibular major connectors the border of the major connector should be 6mm away from the gingival margins in the maxillary arch to avoid any injury.
However, some patients cannot and will not tolerate such. Issues related to position of rests, selection and design of major connectors,. This concept of design will dramatically decrease horizontal torque forces. Removable partial denture design requires a dental technician to restore function, enhance esthetics, and promote longevity.
An approach to partial denture design is presented and a rpd design sequence is proposed. Rpd design steps this section of the design software is divided into 5 steps beginning with “retention grids” where relief wax for open lattices or mesh type denture base. The framework is designed digitally and printed with selective laser melting (slm). Conventional rpd design is frequently bilateral [7] and consists of a major connector that bridges both sides of the arch.

### Figure 8.17 maxillary framework design is developed by the dentist, recorded, and submitted for fabrication.
Thus, the biomechanic design principles of. The design satisfies the criteria for esthetics, retention, support and stability. In this chapter, major and minor connectors are considered separately as to their function, location, and design criteria. Modern rpd design philosophies recognize that removable partial dentures can exert pathologic stress on abutment teeth that can lead to their failure, particularly in extension.
Topics include components of rpds and their functions, design sequences for maxillary and mandibular rpds, and techniques for surveying and determining the most advantageous treatment position. Master cast is scanned (in eos x5 scanner, dentsply sirona, usa) in preparation for cad.
