One-stage ridge splitting in the upper jaw using piezo surgery or a bone-disc technique

Evaluation of Endosseous Implants in One Stage Ridge Splitting Using the Conventional Technique Versus the Use of Piezo Surgery in the Maxilla

We will try two ridge-splitting techniques—piezo surgery and bone discs—to widen narrow upper-jaw bone in adults needing a single-tooth implant.

Quick facts

• Phase: NA
• Study type: Interventional
• Enrollment: 20 (estimated)
• Ages: 20 Years to 48 Years
• Sex: All
• Sponsor: Cairo University (other)
• Drugs / interventions: chemotherapy
• Locations: 1 site (Cairo)
• Trial ID: NCT06891261 on ClinicalTrials.gov

What this trial studies

Participants are randomized to one-stage ridge splitting in the maxilla performed either with piezoelectric bone inserts or with a bone-disc osteotomy, followed by bone chisels, drills, expanders and implant placement. All participants receive baseline CBCT, diagnostic wax-up and stent fabrication, and repeat CBCT at four months to document bone changes. Procedures are performed under local infiltration anesthesia with a full-thickness mucoperiosteal pyramidal flap and periosteal releasing incisions for tension-free closure. The protocol measures ridge width gain and implant site readiness after four months.

Who should consider this trial

Good fit: Adults with a single missing upper tooth, maxillary residual bone height of at least 8 mm and ridge width between 3–5 mm who can undergo CBCT imaging and attend follow-up visits.

Not a fit: Patients who smoke heavily, have uncontrolled metabolic or bone disease, recent head/neck radiotherapy or chemotherapy, pregnancy, active local bone pathology, or who are uncooperative are unlikely to benefit.

Why it matters

Potential benefit: If successful, the preferred technique could widen the alveolar ridge with less bone trauma and improve conditions for stable implant placement.

How similar studies have performed: Piezo-assisted ridge splitting has reported favorable outcomes in several case series and some clinical trials, while the bone-disc approach has less extensive published evidence.
