Comparison of torque measurements and clinical handling of various surgical motors.

Purpose: Modern implant dentistry requires the application of torque during various treatment steps. This study investigated seven different surgical motors for the accuracy of the applied torque and their reliability.

Materials And Methods: The following surgical motors were evaluated: Chiropro 980 (Bienair), INTRAsurg 300 and INTRAsurg 500 (KaVo), Osseocare (Nobel Biocare), Surgic XT (NSK), Elcomed SA-200 C (W and H), and Osseo System (XO Dentalcare).

Stability change of chemically modified sandblasted/acid-etched titanium palatal implants. A randomized-controlled clinical trial.

Aim: The aim of this randomized-controlled clinical study was to examine stability changes of palatal implants with chemically modified sandblasted/acid-etched (modSLA) titanium surface compared with a standard SLA surface, during the early stages of bone healing.

Materials And Methods: Forty adult volunteers were recruited and randomly assigned to the test group (modSLA surface) and to the control group (SLA surface). The test and control implants had the same microscopic and macroscopic topography, but differed in surface chemistry.

Effect of N-chlorotaurine mouth rinses on plaque regrowth and plaque vitality.

The purpose of this 4-day plaque regrowth study was to assess the effect of N-chlorotaurine (NCT) mouth rinses on plaque inhibition and plaque vitality. Eighty volunteers participated in this investigator-blind, randomized, clinical controlled study in parallel groups. No oral hygiene was permitted except rinsing with a 2% or 3% NCT mouth rinse, a positive or a negative control.

[Acceptance of the meridol toothbrush by dental hygienists. A questionnaire study].

Two manual toothbrushes were tested in a questionnaire study by 171 dental hygienists in a crossover design: a new toothbrush with conical filaments (meridol toothbrush, GABA International AG) and a reference toothbrush with end-rounded filaments (ADA toothbrush, American Dental Association). Each trial subject tested the two manual toothbrushes in two consecutive periods. Not only was the immediate impression of interest but also the impression after a period of three weeks.

Enhanced implant stability with a chemically modified SLA surface: a randomized pilot study.

Purpose: Chemical modification to a sandblasted, large-grit, acid-etched (SLA) implant surface has been shown to enhance the rate of osseointegration. The goal of the present study was to examine changes in stability for implants with a chemically modified SLA surface and to compare their outcomes to those of control implants.

Materials And Methods: A randomized controlled trial was conducted with 31 patients.
