Influence of Timing of Implant Placement on Early Healing Molecular Events
Influence of Timing of Implant Placement on Early Healing Molecular Events: A Two-centre, Parallel Group, Pilot Study
Queen Mary University of London
24 participants

INTERVENTIONAL
Conditions
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 the influence of timing of implant placement on wound healing. In addition, there is no data available on the signaling pathways and the expression of healing biomarkers involved in the early stages of osseointegration after immediate implant placement (IP) or delayed implant placement (DP). The primary objective of this study is to describe changes in the expression of inflammatory, angiogenesis and osseous biomarkers of saliva at 1, 3, 7, 15 and 30 days and of PICF at 3, 7, 15 and 30 days after immediate implant placement (IP) compared with delayed placement (DP).

Interventions
In this group, immediately after tooth extraction, a tapered bone level implant (Straumann BLX Implant System, Roxolid, Straumann AG, Basel, Switzerland) will be placed in an ideal prosthetically oriented position to achieve primary stability following the manufacture's guidelines. A prefabricated surgical template based on 3D pre-extraction planning will be used to place the implant. The jumping distance between the implant and the residual buccal bone will be measured and filled with slow resorption bone graft material (Bio-Oss®, Geistlich, Wolhusen, Switzerland) as per standard of practice.
A tapered bone level implant (Straumann BLX Implant System, Roxolid, Straumann AG, Basel, Switzerland) will be placed after complete bone healing (4 - 6 months after tooth extraction) in an ideal prosthetically oriented position to achieve primary stability following the manufacture's guidelines. Guided bone regeneration (GBR) will be performed simultaneously with the aim to re-establish the bone contour and treat any fenestration/dehiscence if needed. A bovine osteoconductive graft (Bio-Oss®, Geistlich, Wolhusen, Switzerland) will be loosely compacted on the buccal aspect of the implant and covered with a collagen membrane (Bio-Gide®, Geistlich, Wolhusen, Switzerland).
