A comparison of different methods and materials for establishing maximal intercuspal position: A clinical study.

Statement Of Problem: Which method or material used to record the intercuspal position yields the best accuracy of location of the maxillary and mandibular casts is unclear.

Purpose: The purpose of this clinical study was to determine the most reliable method of recording a patient's maximal intercuspal position by comparing 2 common methods with 2 popular registration materials.

Material And Methods: Complete arch impressions were made of both jaws with a polyvinyl siloxane impression material in a metal stock tray followed by 4 interocclusal registrations for each of the 17 participants.

A comparison of the accuracy of polyether, polyvinyl siloxane, and plaster impressions for long-span implant-supported prostheses.

Purpose: The purpose of this study was to compare the capacity of different impression materials to accurately reproduce the positions of five implant analogs on a master model by comparing the resulting cast with the stainless steel master model. The study was motivated by the knowledge that distortions can occur during impression making and the pouring of casts and that this distortion may produce inaccuracies of subsequent restorations, especially long-span castings for implant superstructures.

Materials And Methods: The master model was a stainless steel model with five implant analogs.

The three-dimensional casting distortion of five implant-supported frameworks.

The aim of this study was to assess three-dimensional distortion in cast full-arch, screw-retained titanium implant frameworks. A conventional commercial laboratory one-piece casting was used implementing the lost-wax technique. Five wax patterns were fabricated on a die-stone cast poured from a plaster impression of a five-implant brass analog.

A protocol for maxillary reconstruction following oncology resection using zygomatic implants.

The purpose of this clinical report is to present a surgical and prosthodontic reconstructive protocol for 20 patients who underwent maxillary resection following malignancy to the head and neck region. This protocol was developed over a period of 7 years while treating a series of 20 maxillary resections due to oncology. Patients were reconstructed prosthodontically using fixed-removable overdentures or fixed prostheses, with and without separate obturators.

Surgical modifications to the Brånemark zygomaticus protocol in the treatment of the severely resorbed maxilla: a clinical report.

Purpose: The Zygomaticus dental implant, designed by Nobel Blocare, was developed for the treatment of the severely resorbed maxilla. Brånemark has reported an overall success rate of 97.6% with the placement of 183 implants over the last 12 years.
