Brief Summary:
Dental implants have been on the market for several years and they are routinely used to replace single/multiple missing teeth with a high success rate. However, there is still a limited number of studies comparing hydrophilic titanium and zirconia implants. In addition, there is no data available on the signalling pathways and the expression of healing biomarkers involved in the early stages of osseointegration around zirconia surface implants placed with guided bone regeneration (GBR).
This study aims 1) to describe and compare the early wound healing molecular pathways, and the 2) vascularization patterns of mucosal tissues after the placement of hydrophilic titanium or zirconia implants with simultaneous guided bone regeneration (GBR).
In this study, the investigators will assess the expression of inflammatory, angiogenesis and osseous biomarkers of PICF at 3, 7, 15 and 30 days after the placement of hydrophilic titanium or zirconia dental implants with simultaneous GBR and of saliva at day 1, 3, 7, 15 and 30.

Detailed Description:
This is a two-centre prospective, parallel-group pilot study which will consist of 10-11 visits over a minimum period of 14 months. The study will take place at the Centre for Oral Clinical Research (COCR), at the Institute of Dentistry, Barts and The London School of Medicine and Dentistry, Queen Mary University of London (main centre), United Kingdom and at Clinic of Reconstructive Dentistry, University of Zurich, Zurich in accordance with local guidelines and procedures/interventions detailed below.
