Jawbone graft showdown: which technique works best for dental implants?
NCT ID NCT07656662
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two surgical techniques used to rebuild the jawbone so dental implants can be placed. The Split Box Technique and the Split Bone Block Technique both aim to increase bone width. Researchers looked back at records of 31 patients treated at a university dental clinic to see which method led to more bone gain, better long-term stability, and higher implant survival rates.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help dentists choose the better technique for rebuilding jawbone before placing dental implants, leading to more predictable outcomes.
- What could go wrong
- This is a small, retrospective study (31 patients) that only looks back at past records. Results may not apply to all patients, and the study does not test new treatments.

Who is studied
The study population consisted of adult patients with horizontal alveolar ridge deficiencies who underwent horizontal ridge augmentation using either the Split Box Technique or the Split Bone Block Technique before implant placement. Patients were treated at Marmara University Faculty of Dentistry between January 2014 and January 2026 and had complete clinical records and CBCT imaging available for retrospective evaluation.

Inclusion Criteria: * Age ≥18 years. * Patients with horizontal alveolar ridge deficiency requiring horizontal ridge augmentation before implant placement. * Patients treated with either the Split Box Technique (SBT) or Split Bone Block Technique (SBBT) at Marmara University Faculty of Dentistry between January 2014 and January 2026. * Availability of complete radiographic records, including CBCT scans obtained preoperatively (T0), 6 months after augmentation (T1), and during long-term follow-up after prosthetic loading (T2). * Availability of complete clinical records and follow-up data. Exclusion Criteria: * Incomplete clinical or radiographic records. * Patients lost to follow-up. * Presence of uncontrolled systemic diseases or conditions known to adversely affect bone healing. * Use of medications known to interfere with bone metabolism or healing. * Active infection at the augmentation site or complications that altered the planned treatment protocol.
