Perfect digital impression of natural abutment teeth without using retraction cords.

Digital technologies are gradually gaining ground in dentistry. In particular, taking impressions with intraoral scanners is becoming routine; however, even this must often be preceded by the use of retraction cords. This article presents an innovative technique to record digital impressions of natural tooth abutments using interim restorations relined with impression material instead of retraction cords.

Bone contact around osseointegrated implants: a histologic study of acid-etched and machined surfaces.

Current literature reports that surface acid etching can improve bone--implant contact (BIC). The aim of this study was to evaluate the differences of BIC between acid-etched (Osseotite) and machined surface implants. Six white New Zealand mature rabbits were used in the present investigation.

Sandblasted and acid-etched dental implants: a histologic study in rats.

Purpose: Current literature has revealed that surface etching of endosseous implants can improve bone-implant contact. The aim of this study was to evaluate the differences in bone-implant contact (BIC) between sandblasted/acid-etched and machined-surface implants.

Materials And Methods: Thirty-two Sprague-Dawley rats were used in this study.
