Horizontal ridge augmentation using a customized porous zirconia shell
Tomographic Evaluation of The Dimensional Changes After Horizontal Ridge Augmentation of the Lower Posterior Mandible Using a Novel Customized Porous Zirconia Shell Technique: Clinical Case Study.
This tests whether a custom porous zirconia shell can rebuild missing width in the lower back jaw for adults who need dental implants.

What this trial studies
This case series compares a customized porous zirconia shell technique to traditional autogenous bone block methods for horizontal ridge augmentation. The zirconia shells are patient-specific, non-resorbable devices placed over the deficient alveolar ridge to create and maintain space for bone regeneration. Participants are adults with Seibert class I posterior mandibular deficiencies who receive the shell placement and are followed for bone fill and complications. Outcomes include horizontal bone gain, wound healing, and donor-site morbidity avoidance compared with expectations from the Khoury technique.
Who should consider this trial
Good fit: Adults over 18 with a Seibert class I deficiency in the lower posterior jaw, adequate inter-arch space, good oral hygiene, motivation for implant treatment, and no systemic conditions affecting healing are ideal candidates.
Not a fit: Patients who smoke, are pregnant, have poor oral hygiene, active systemic conditions that impair healing, or who need vertical or complex defects may not benefit from this technique.
Why it matters
Potential benefit: If successful, this could restore bone width needed for implants while avoiding bone harvesting and its associated donor-site pain and complications.
How similar studies have performed: Autogenous block grafting like the Khoury technique has an established track record, while customized porous zirconia shells are a relatively novel approach with limited published clinical series to date.
