Removable prosthodontic impressions
Article Abstract:
A new technique has been developed for making prosthodontic impressions for removable complete dentures. A prosthodontic impression is a model of a patient's gums that can be used to fit their dentures. The new technique is a very specific technique that is simple, fast and accurate. A preliminary cast is made using quick-setting stone. The preliminary cast can be poured by a member of the dental office staff. The final impression can be poured within five to 10 minutes using a light-curing prosthodontic resin. A staff member can also pour the final impression tray in states in which it is legal. This technique does not involve the use of the traditional wax relief of the preliminary cast. It can also be done at a lower cost to the patient than other impression techniques.

Keeping interocclusal records: how to solve a common problem
Article Abstract:
Increased accuracy of interocclusal records (IOR) may improve the treatment of patients with dental implants, or bone-anchored prostheses to replace missing teeth. The interocclusal space is the space situated between the contacting surfaces of opposing teeth of the mandibular and maxillary arches. Materials used to make IORs include wax, zinc oxide-eugenol pastes, non-eugenol pastes, silicone putty, polyether and non-slumping silicone paste. Polyether and non-slumping silicone are the easiest materials to use, and they provide the most accurate IOR. The main disadvantage of polyether is its bitter taste. Techniques used to make IORs have also changed. The most reproducible IOR technique involves injecting non-slumping silicone paste after the patient's jaws are closed.

When to use fillers, build-ups or posts and cores
Article Abstract:
Old restoration materials should be removed before placing fixed prosthodontics and crowns. The ideal type for filler material is a compomer and should be used for minor tooth preparations only. Build-ups are needed for a stronger basis and recent trends have seen the discontinuation of pin use, except for titanium pins. Most dentists prefer using a pre-fabricated post-and-core procedure instead of a customized one. Flexible posts are becoming more popular for added resilience.
