Implant-supported maxillary denture retained by a telescopic abutment system: A clinical report.

An implant-supported fixed dental prosthesis is one of the treatment options for an individual with a completely edentulous maxilla. However, a screw-retained or cemented prosthesis can make oral hygiene difficult, especially for patients with a history of periodontal disease or disabilities. Compared with maxillary fixed dental prostheses, implant-supported overdentures offer similar retention and function and facilitate esthetics, phonetics, and hygiene.

Comparative analysis of 4 impression techniques for implants.

Purpose: This in vitro study investigated 4 impression techniques to determine their dimensional accuracy in comparison with a standard technique.

Materials And Methods: A master metal framework with 2 inner hex implants (SIN; Sistema de Implante Nacional Ltda., Sao Paulo, Brazil) was used as a standard for the comparisons.
