Generally, it is recommended that complete dentures be removed at night to allow tissues to rest. [Medline]. Figure 1. The patella may or may not be resurfaced. Research studies with sound parameters may help to create more reliable longevity estimates for dental clinicians to share with their patients. In turn, this ensures that fixed dentures are more functional than removable dentures. Mazurat RD. Because of the many variables that exist, it is difficult to know for certain how long complete dentures may last. Maintenance and repairing: Maintenance and repairing of fixed partial dentures is more difficult than that of removable partial dentures. Relative contraindications to dental implantation include: Lack of dental health (presence of carious teeth, for example); Poor oral hygiene (this item is a direct indication for removable prosthesis); Gingivitis (inflammation of the gums infectious and noninfectious nature); Marginal periodontitis (inflammation of the tissues surrounding the teeth); Pre-Surgical Workup.

A plastic spacer is introduced between the metallic surfaces to ensure smooth movement. When retiring for the night, the complete denture should be submerged in water to avoid the development of dimensional changes from dehydration. Casts are mounted on an articulator, which emulates dynamic occlusal relationships. [9] depicted in the image below, describes viscous tension eloquently. Figure 1.12 a, b, c. In addition to the tooth loss, the teeth that are around the gap and not in their normal position and the decays on the adjacent teeth are the reasons that make the treatment difficult.

Hand soap or dishwashing soap may be used, but toothpastes are generally regarded as being too abrasive and should be avoided. 14, 433, 441-444. Therefore, implant applications should be taken into consideration while the indications and contraindications are evaluated.
