Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary aim is to determine the effect of a short term disruption of the blood flow in the gingiva next to an implant and the contralateral tooth, in order to compare the functionally active collateral circulation in the attached gingiva at these respective regions. Using Laser Speckle Contrast Imaging technique (LSCI), which provides blood perfusion data, the investigators will have the possibility to detect functional alterations in gingival microcirculation during and after a short term compression of the gingiva. The secondary aim is to assess and compare the time course of the restoration of the circulation on the affected areas. Further aims are to observe if the compensation capability of the circulation is influenced by gingival thickness (biotype) and patient's gender.

Study Groups

Implant
Post-occlusive reactive hyperaemia test (PORH test) in the gingiva at a dental implant born crown in the front region of the jaw
Post-occlusive reactive hyperemia test (PORH test)
Compression is applied on the buccal side of the attached gingiva, perpendicular to the long axis of the natural or implant born crown 2 mm far from the gingival margin.
Tooth
Post-occlusive reactive hyperaemia test (PORH test) in the gingiva at the contralateral natural tooth
Post-occlusive reactive hyperemia test (PORH test)
Compression is applied on the buccal side of the attached gingiva, perpendicular to the long axis of the natural or implant born crown 2 mm far from the gingival margin.
