Abstract

Objective

The aim of the present pilot study is to investigate the effects of hydrophilicity and microtopography of titanium implant surfaces on initial supragingival plaque biofilm formation.

Materials and Methods

Test specimens were manufactured from commercially pure grade 2 titanium according to one of the following procedures: polished (P), acid-etched (A), chemically modified (mod) A (modA), sand-blasted large grit and A (SLA), and modSLA. Intraoral splints were used to collect an in vivo supragingival plaque biofilm in each group at 12, 24, and 48 h. Stained plaque biofilm (PB) areas (%) were morphometrically assessed.

Results

All groups exhibited significant increases of mean PB areas over time (p < 0.001; respectively). Morphometrical analysis revealed the following mean PB areas: 12 h: SLA = modSLA > P > A = modA (p < 0.001; respectively); 24 h: SLA > modSLA = P >A = modA (p < 0.001; respectively); 48h: SLA = modSLA = P >A = modA (p < 0.001; respectively).

Conclusions

Within the limits of a pilot study, it could be concluded that hydrophilicity had no apparent effect, while microtopography had a highly uneven and unpredictable influence on supragingival plaque biofilm formation.

Zusammenfassung

Fragestellung

Das Ziel der vorliegenden Pilotuntersuchung war, den Einfluss der Hydrophilizität und Mikrotopografie von Titanimplantatoberflächen auf die supragingivale Plaque Biofilmbildung zu untersuchen.

Material und Methode

Standardisierte Titanplättchen wurden mit nachfolgenden Oberflächencharakteristika hergestellt: poliert (P), säuregeätzt (A), chemisch modifiziert hydrophil (mod) A (modA), sandgestrahlt und säuregeätzt (SLA) und modSLA. Ein intraorales Schienensystem diente zur in vivo supragingivalen Plaque-Biofilmformation in jeder Gruppe nach 12, 24 und 48 Stunden. Die Bewertung gefärbter Plaque-Biofilm (PB) Areale (%) erfolgte morphometrisch.

Ergebnisse

Alle Gruppen zeigten einen signifikanten Anstieg der mittleren PB-Areale über die Zeit (p < 0,001; respektive). Die morphometrische Analyse ergab die nachfolgenden mittleren PB Areale: 12 h: SLA = modSLA > P >A = modA (p < 0,001; respektive); 24h: SLA > modSLA =P > A = modA (p < 0,001; respektive); 48 h: SLA =modSLA = P > A = modA (p < 0,001; respektive).

Schlussfolgerung

Die Ergebnisse der vorliegenden Pilotuntersuchung haben gezeigt, dass die Hydrophilizität keinen Effekt und die Mikrotopografie einen nur uneinheitlichen sowie unvorhersehbaren Einfluss auf die supragingivale Plaque-Biofilmformation auf Titanimplantatoberflächen hatte.
