Dental Implants Clinical Trial
Official title:
Comparison of Microvascular Reactivity Assessed by Post-occlusive Reactive Hyperaemia Test in Gingiva at Natural Tooth and at Implant Borne Crown
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.
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.
