Study Notes
-
Full palatal coverage is a major connector used in specific applications for Kennedy class one patients on the maxillary arch. Prioritizing patient comfort and symmetry, the connector follows these guidelines:
-
Anterior Palatal Bars:
- Broad anterior palatal bar: Thinner and one-piece metal structure connecting the anterior teeth with speech issues due to thickness.
- Posterior palatal bar: Half-teardrop shaped with thickness increasing towards the posterior, parallel to the anterior palatal bar and perpendicular to the median suture.
- Both anterior and posterior bars maintain a minimum distance of 6mm from the gingival margins of the anterior teeth.
-
Full palatal coverage connector:
- Full acrylic coverage for Kennedy class one maxillary cases.
- Includes a metal base for posterior meshwork placement.
- Offers additional support through a posterior palatal seal.
- Can be used to cover Tori or Taurus when present.
- More adjustable than all-metal palates.
-
When not using full palatal coverage, a horseshoe shape is an alternative connector for dentures.
-
Lingual bars (simple and blanket) are options for mandibular major connectors.
-
Width and thickness of connectors depend on the number of missing teeth.
-
Rigidity of the connector and patient comfort are key considerations.
