Analysis of Titanium Surfaces Following non-Surgical Instrumentation Techniques to Manage Peri-Implant Mucositis – an in-Vitro Study.
Objectives: Biofilm accumulation is the primary cause of peri-implant mucositis. Complete removal is a challenge as traditional instrumentation techniques are often hindered by the shape and positioning of implants. Inappropriate instrument material or adaption may result in microscopic surface alterations during biofilm removal and roughening of the titanium surface may occur. The aim of this study is to assess the extent of surface alterations inflicted on smooth implant surfaces following instrumentation with established hygiene modalities.
Methods: Biofilm of S. Mutans were formed on 20 identical cylindrical titanium surfaces (4mm diameter) to mimic dental implant surfaces over a 48-hour period. Specimens were divided into groups of 5, mounted on a 3D printed alveolar ridge with a gingival mask and treated as follows: group 1: untreated control, group 2: titanium curettes, group 3: air polishing with erythritol, group 4: modified power brush at a 45-degree angle. Each specimen was treated with a single modality for 10 seconds for 5 repeats. Surface roughness and debridement efficiency was assessed against untreated controls using non-contact profilometry and scanning electron microscopy.
Results: Preliminary data indicates that surfaces varied with applied treatment. The power brush group exhibited the least surface alteration compared to untreated controls. Loss of original finish and marked surface alterations was observed in the curette group compared to all other test groups. Minimal surface alteration was observed in air-polish group, however residual powder was observed on all surfaces following instrumentation.
Conclusions: Complete biofilm removal without inflicting surface alterations on smooth cylindrical titanium surfaces is difficult to achieve with instruments designed to adapt to root surface anatomy rather than implant structures. Clinical impact of these findings requires further investigation.
