Study summary

This randomized controlled study aims to evaluate the clinical, radiographic, and histologic efficacy of using bioactive glass bone graft (UNIGRAFT by Biomed Inc., USA) compared to a conventional xenograft in maxillary sinus augmentation procedures. A total of 20 patients classified as SA4 according to the Misch classification will be enrolled and randomly allocated into two groups. Outcomes will be assessed using Cone Beam Computed Tomography (CBCT) for vertical bone gain and, where applicable, histologic analysis. The study is conducted at the Faculty of Dentistry, Suez Canal University.

Read the detailed description

The aim of this clinical study is to compare the performance of a novel bioactive glass bone graft (UNIGRAFT) with a standard xenograft material in open sinus lift procedures for patients with severely atrophic maxillary posterior ridges (Misch SA4 classification). The trial is designed as a parallel-arm, randomized controlled study involving 20 patients. Each participant will undergo maxillary sinus augmentation using either the bioactive glass or the xenograft, followed by a healing period prior to implant placement.

Radiographic evaluation using CBCT will be conducted to assess vertical bone height gain pre- and post-operatively. Additionally, histological samples may be obtained during implant placement in indicated cases to evaluate bone quality. The primary endpoint is vertical bone gain after 6 months, and secondary endpoints include bone density, complication rate, and histologic characteristics. The study will follow strict ethical guidelines and is approved by the institutional ethics committee of Suez Canal University.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
