    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.
