Kennedy classification is governed by the most posterior edentulous area that is being restored. explanation of the role of the denture and the way a removable partial denture understanding partial denture design provides a step by step highly illustrated guide to this difficult but core area of dentistry the first section of the book is dedicated to general principles of partial dentures focussing on how they work the second section allows students to put theory into practice profiling the patient and the … Advantages of these are their rigidity and minimal soft tissue coverage yet still having good resistance to deformation. Followed by Class II in both maxillary and mandibular arch with an average of 16.3% in maxillary arch and 14.8% in the mandibular arch. It may be fixed (i.e. It may be used when a lingual plate is compromising aesthetics.. In rare cases where the inclination of the remaining anterior teeth is problematic and the use of a lingual connector inappropriate, a buccal bar can be considered. Within the design process (and prior to the master impression stage of denture construction), modifications may be suggested to teeth. Partial dentures are made from a combination of metal and acrylic – which gives them the strength to handle your needs for chewing and speaking, while also looking natural. Once the partial denture has been designed, the shade and mould of the replacement teeth can be selected.

Partial denture: A prosthesis that replaces one or more, but not all of the natural teeth and supporting structures. Along with the lingual plate it is the most commonly used type of connector in the lower arch.

Removable partial dentures can meet the long-term goals of oral rehabilitation if the basic principles of treatment planning and design of the prosthesis are carried out. distal abutments) or financial limitations.
