About

Apply LSCI method for follow-up changes in regional blood flow after compression of the gingiva in order to compare the vascular reactivity of the attached gingiva at implant versus at tooth.

Full description

This study will examine the effects of implantation and peri-implant soft tissue shaping on the circulation and the regeneration processes of the human gingiva.

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.
