Plain English summary of protocol
Background and study aims
Several techniques have been described for maxillary sinus graft augmentation such as the lateral window technique, or crestal approach with osteotomes or osseodensification. Platelet-rich fibrin (PRF) has been used in maxillary sinus lift procedures due to its ability to fasten the soft and hard tissue healing. PRF is an autologous platelet concentrate containing leukocyte. This study aims to evaluate the potential of PRF in combination with Synthetic hydroxyapatite Nanobone ® to enhance bone regeneration in sinus floor elevation with Lateral window technique in a split-mouth study, twelve sinus graft surgeries were carried out.
Who can participate?
Adults over the age of 18 years who attend consultation in University Institute of Health Sciences -IUCS in Portugal.
What does the study involve? (for participants)
Participants are asked to join this study in the implant consultation in Cespu University dental clinic . Participants must pass the screening the inclusion criteria. Participants must have pneumatized sinus with insufficient bone height for implant placement. Those in the first group as asked to give blood at the usual donation intervals (based on their gender). The study will last 6 months. Participants also complete informed consent and questionnaires before being choosen to participate in the study.
What are the possible benefits and risks of participating?
Potential faster bone and soft tissue healing using PRF
Where is the study run from?
University Institute of Health Sciences -IUCS Portugal in Cespu university dental clinic and Coimbra University Hard tissue Laboratory.
When is the study starting and how long is it expected to run for?
January 2023 to December 2023
Who is funding the study?
Investigator initiated and funded

| Scientific title | Clinical application of platelet-rich fibrin mixed with Synthetic Hydroxyapatite (Nanobone) material in maxillary sinus augmentation - randomised clinical trial |
| Study objectives | The aim of this clinical-histological study is to evaluate the potential of PRF in combination with Synthetic hydroxyapatite Nanobone to enhance bone regeneration in sinus floor elevation with Lateral window technique. |
| Ethics approval(s) |
Approved 14/07/2023, CESPU Ethics Committee (Rua Central de Gandra, Gandra, 4585-116, Portugal; +351 224 157 100; sec.ce@cespu.pt), ref: CE/IUCS/CESPU-18/23 |
| Health condition(s) or problem(s) studied | Reduced bone height in the posterior maxilla (1-4 mm) |
| Intervention | Participants will be randomized to test or control treatment lateral window technique for sinus augmentation using Liquid PRF with Nanobone / Nanobone alone based on computer-generated random codes. The allocation will be hidden from the surgeon by opaque envelopes to be opened right before the surgical procedure. With the exception of the surgical technique used, all methodology will be similar for both groups. Patients will be followed up for 6 months after surgery and until the implants are loaded with the final restoration. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure(s) |

| Key secondary outcome measure(s) |
1. Quality of life measured using the Oral Health Impact Profile 14 translated in Portuguese |
