About this study

Official title: A Prospective Controlled Clinical Study Evaluating the Effect of Bone and Autologous Dentin Grafting in the Osteotomy Gap During the Split Crest Procedure With Simultaneous Implant Placement

This prospective controlled clinical study evaluates the effectiveness of adding bone graft or dentin graft material during the split crest (alveolar ridge splitting) procedure for horizontal ridge augmentation with simultaneous implant placement.

The study includes patients with narrow alveolar ridges requiring implant-supported rehabilitation. Participants are divided into three groups: split crest without grafting, split crest with bone graft, and split crest with dentin graft. The aim is to determine whether the addition of graft material to the osteotomy gap improves bone width, bone density, and primary implant stability compared to the split crest technique alone.

Read more

Clinical and radiographic assessments are performed using cone-beam computed tomography (CBCT) and implant stability measurements (ISQ values) before surgery, immediately after implant placement, and three months postoperatively. All patients are monitored over a one-year follow-up period to evaluate healing progression and treatment outcomes.

This study seeks to identify the most effective approach for horizontal ridge augmentation and to improve clinical decision-making in implant dentistry. The findings aim to contribute to optimizing surgical protocols, enhancing implant stability, and improving long-term functional outcomes for patients.

Participation is voluntary, and all procedures are conducted in accordance with approved ethical standards and clinical guidelines.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Split Crest TechniqueProcedure or surgery

    A surgical split crest (alveolar ridge splitting) procedure performed to increase horizontal alveolar bone width and enable simultaneous dental implant placement. A controlled osteotomy is created along the crest of the ridge, followed by gradual expansion of the buccal cortical plate to form an osteotomy gap for implant insertion.

Questions about this trial

What is this clinical trial studying?

A study testing Split Crest Technique in people with Alveolar Bone Resorption and Alveolar Bone Grafting, run by Vladimir Biocanin at 1 site in Serbia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Serbia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in alveolar ridge width following split crest proceduree with or without bone or dentin grafting (time frame: Preoparative, Immediately postoperative, and 3 months after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Dec 2025.
