Trial summary

This was a prospective, randomized clinical trial conducted at the Department of Oral and Maxillofacial Surgery, Ege University. Patients exhibiting horizontal bone insufficiency (residual crest width < 4 mm) in the posterior mandible received dental implants with two techniques: osseodensification or crest split.

About this study

Official title: Clinical and Radiological Comparison of Two Different Expansion Techniques in Patients With Horizontal Bone Sufficiency

This was a prospective, randomized clinical trial conducted at the Department of Oral and Maxillofacial Surgery, Ege University. Patients exhibiting horizontal bone insufficiency (residual crest width < 4 mm) in the posterior mandible received dental implants with two techniques: osseodensification or crest split. The investigator compared to clinical and radiological outcomes of these techniques.

Read the detailed description

This prospective, parallel-group randomized clinical trial was conducted at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Ege University, İzmir, Turkey, between February 2021 and August 2023.Patients exhibiting horizontal bone insufficiency (residual crest width < 4 mm) in the posterior mandible received dental implants with two techniques. The primary predictor variable was the ridge expansion technique: Osseodensification (Group 1, n=10 patients, 21 implants) or Crest Split (Group 2, n=10 patients, 25 implants). primary outcome variables were primary stability. The secondary outcome variables were clinical bone expansion, intraoperative/postoperative complications, marginal bone level, plaque accumulation, and bleeding on probing.

What participants receive

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

  • Bone expansion and implant placement with crest splitProcedure or surgery

    Bone expansion was provided with chisel and mullet. Implant was inserted following expansion.

  • Bone expansion and implant placement with specifically design drillsProcedure or surgery

    Bone expansion was provided with implant drills. Implant was inserted following expansion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean of implant stability quantity (ISQ) value

    Calculation of ISQ value: Measurement for each implant using resonance frequency analysis (RFA)

    Measured: At surgery

  2. Mean of torque value

    Calculation of torque value: Measurement for each implant using a ratchet and torque wrench

    Measured: At surgery

Secondary outcomes (3)
  1. Marginal bone level

    Change in peri-implant bone level

    Measured: through study completion, ana average of 2 year

  2. Complication

    Number of operative and postoperative complications

    Measured: through study completion, an average of 2 year

  3. Peri-implant health

    Calculation of bleeding on probing and plaque accumulation. Bleeding on probing: Assessment of bleeding presence/absence using a periodontal probe.

    Plaque accumulation: Assessment of plaque presence/absence using a modified plaque index.

    Measured: at 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Bone expansion and implant placement with crest split and Bone expansion and implant placement with specifically design drills in people with Horizontal Alveolar Bone Loss and Implant Therapy, run by Ege University at 1 site in Turkey (Türkiye).

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 3 inclusion and 6 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 2 Oct 2026. 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 Turkey (Türkiye). 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?

Mean of implant stability quantity (ISQ) value (time frame: At surgery). The study lists 2 primary outcomes in all. 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 2 Oct 2026.
