Open Lattice Work on RPD Frameworks
Posted on 02/15/2012
Among the three base retentive options for frameworks, open lattice work is the preferred option for all distal extension RPDs. This is because the lattice work allows for more and thicker acrylic through the large openings, as opposed to meshwork which has very small openings where acrylic cannot develop the same degree of bulk. In the long term, that bulk helps to prevent fracture.
The design elements of the open lattice work include the following specifications:
1. On the maxillary, the latticework should extend two thirds of the distance to the hamular knotch
2. On the mandibular, the latticework should extend two thirds of the distance to the retromolar pad.
3. Lattice work is completed embedded in acrylic
4. Lattice work struts meet the major connector at a butt joint.
