Summary

This study aims to characterise the stability of crestal bone levels one year after loading, the associated aesthetic outcomes, immunological response, prosthodontic outcomes as well as overall patient reported outcome measures for modSLA (SLActive, Institut Straumann AG, Switzerland) and NGA (TiUltraNP, Nobel Biocare AG, Switzerland) dental implants.

Detailed description

Ultra-hydrophilic SLActive (modSLA) implants have been extensively studied in pre-clinical and clinical studies, demonstrating their pro-osteogenic nature and long-term maintenance of facial bone and aesthetics. A novel multi-zone novel gradient anodized (NGA) hydrophilic surface (TiUltra) has recently been introduced to clinical practice. Pre-clinical studies have demonstrated that the smoother coronal aspect achieved stable soft tissue adhesion. In clinical practice, prosthetically driven implant placement, particularly in the anterior maxilla, may result in a buccal dehiscence that is commonly treated with guided bone regeneration (GBR). Currently no studies have been published investigating differences between these commercially available implant surfaces (modSLA, NGA). This prospective, single centre randomised clinical trial will recruit 39 patients who require a single tooth extraction in the anterior maxilla for a Type IIc implant placement. Patients enrolled in the study will be allocated to one of three implant groups: * Group 1: NGA Implant (NobelActive TiUltraNP, Nobel Biocare AG, Switzerland) * Group 2: BLX implant (BLX) modSLA Surface (BLX, SLActive, Roxolid, Institut Straumann AG, Switzerland) * Group 3: TLX implant (TLX) modSLA Surface (TLX, SLActive, Roxolid, Institut Straumann AG, Switzerland). This study aims to characterise the stability of crestal bone levels one year after loading, the associated aesthetic outcomes, immunological response, prosthodontic outcomes as well as overall patient reported outcome measures.
