Complete Denture

Complete dentures are full-coverage oral prosthetic appliances that replace a complete edentulous arch. These are dentures that are fabricated using acrylic resin and that rely on the alveolar ridge, saliva, and other supporting structures for retention.

Send Case
  • Complete dentures are full-coverage oral prosthetic appliances that replace a complete edentulous arch.

  • These are dentures that are fabricated using acrylic resin and that rely on the alveolar ridge, saliva, and other supporting structures for retention.

  • Intraoral cancer can cause a loss of gross intraoral tissue, resulting in an edentulous dental arch; the complete denture prosthesis would not only replace these teeth but also fill in the portion of missing tissue

  • Complete dentures are an alternative to dental implants that have been deemed inappropriate by the patient and/or doctor because of financial constraints, a medically compromised status that contraindicates surgery, or inevitable damage to vital structures such as maxillary sinuses, nerves, and vessels

  • Complete dentures are fabricated using the injection mold technique for long term stability. The materials feature a surface quality and fracture toughness equivalent to that of heat-curing polymers and are even superior to many other heat-curing polymers, for instance with regard to the exceptionally low residual monomer content. The high degree of monomer conversion during the polymerization process results in a residual monomer content of less than 1.5%, which is very low for a self-curing polymer (limit values according to ISO 20795-1: 4.5% for self-curing polymers and 2.2% for heat-curing polymers)

  • Digital Complete Dentures are also available:

    • Ivoclar Vivadent Digital Denture
    • Dentsply Sirona Lucitone Digital Denture

Validations

“…Injection molding has been demonstrated in a number of studies to produce better denture base adaptation than the conventional denture processing technique. This study investigated overall base plate adaptation accuracy denture bases produced by conventional pressure packing or injection molding techniques. The dimensional accuracy of the injection molded PMMA was better than the conventional PMMA, and these results are in agreement with Huggett et al. Comparative studies have demonstrated that modern injection molding techniques result in fewer dimensional inaccuracies than conventional processing techniques. This is based on the principle that throughout the carefully controlled polymerization procedure, PMMA resin is continuously injected at pressure to compensate for polymerization shrinkage…”
