New Tooth-Bone plate may speed up jaw surgery and improve accuracy
NCT ID NCT07622758
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 20 patients who had jaw surgery to correct facial deformities. Researchers compared a new tooth-bone dual-support guide plate to the usual CAD/CAM splints to see which was more accurate and faster. The goal was to find out if the new plate could improve surgery results and save time in the operating room.
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 the new plate proves more accurate and faster, it could improve surgical outcomes and reduce time in the operating room for jaw correction surgeries.
- What could go wrong
- This is a small, retrospective study with only 20 participants, so results may not apply to all patients. It does not test a new drug or treatment, only a surgical tool.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Patients primarily diagnosed as "dentofacial deformities" who are scheduled for "surgery-first" bimaxillary orthognathic surgery. They are cases eligible for the surgery-first approach after joint assessment by craniomaxillofacial surgeons and orthodontists. Orthodontists confirm that satisfactory occlusal relationships can be achieved via postoperative orthodontic treatment. Preoperative requirements are as follows: no or mild anterior crowding, flat or shallow Spee's curve, slight incisor inclination, harmonious maxillary and mandibular dental arches, and at least three stable occlusal contacts in the transitional occlusion.

Inclusion Criteria: 1. Age: 18 to 40 years old. 2. Diagnosis: Patients treated at Plastic Surgery Hospital, Chinese Academy of Medical Sciences. Diagnosed with dentofacial deformity upon comprehensive evaluation by two senior attending plastic surgeons. 3. Surgical plan: Scheduled for bimaxillary orthognathic surgery, which may be combined with subapical osteotomy of the maxilla and mandible or genioplasty. 4. Treatment protocol: Cases eligible for the surgery-first approach after joint assessment by craniomaxillofacial surgeons and orthodontists. Orthodontists confirm that satisfactory occlusal relationships can be achieved via postoperative orthodontic treatment. Preoperative requirements are as follows: no or mild anterior crowding, flat or shallow Spee's curve, slight incisor inclination, harmonious maxillary and mandibular dental arches, and at least three stable occlusal contacts in the transitional occlusion. 5. Agreement to follow-up and signed informed consent form. Exclusion Criteria: 1. Presence of comorbid diseases or symptoms that may increase surgical risks or compromise surgical outcomes, as determined by two senior plastic surgeons, including but not limited to hypertension, diabetes, immune thrombocytopenic purpura, and hemoglobin (Hb) ≤ 100 g/L. 2. Body dysmorphic disorder, history of psychiatric disorders, or excessively demanding patients with unrealistic expectations. 3. Facial skeletal tumors. 4. Revision surgery after prior orthognathic procedures.
