Evaluation of a variable-thread tapered implant in extraction sites with immediate temporization: a 3-year multicenter clinical study.

Background: The purpose of this clinical study is to evaluate the radiographic bone remodeling, survival rate, and soft tissue health surrounding a variable-thread tapered implant immediately placed in extraction sites.

Methods: Sixty implants were placed in 55 patients at six centers according to a predetermined protocol. All implants were placed in extraction sockets and were subjected to immediate temporization and function.

Two-year evaluation of a variable-thread tapered implant in extraction sites with immediate temporization: a multicenter clinical trial.

Purpose: The purpose of this clinical trial was to evaluate the survival rate, bone remodeling, and soft tissue health surrounding variable-thread tapered implants placed in fresh extraction sites and loaded immediately.

Materials And Methods: Sixty implants were placed in 55 patients at six centers according to a predetermined protocol. All implants were placed in extraction sockets and were subjected to immediate temporization.

Functional quorum sensing systems affect biofilm formation and protein expression in Yersinia pestis.

Gram-negative bacteria predominantly use two types of quorum sensing (QS) systems--LuxI-LuxR, responsible for synthesis of N-acylhomoserine lactones (AHL or AI-1 signal molecule), and LuxS, which makes furanones (AI-2 signal molecule). We showed that LuxS and two LuxI-LuxR (YtbIR and YpsIR) systems are functional in Y. pestis.
