Computer-guided vs. Conventional Cortical Shell Technique for Horizontal Augmentation
Alveolar Bone Resorption, Horizontal Ridge Deficiency
About this trial
This is an interventional treatment trial for Alveolar Bone Resorption focused on measuring alveolar ridge deficiency, computer guided surgery, chin graft
Eligibility Criteria
Inclusion Criteria:
- patient free from any systemic condition.
- Edentulous anterior maxilla with a horizontal deficient alveolar ridge that is less than 4 mm measured from outer buccal cortices to outer palatal cortices.
- Highly motivated patients are willing for the surgical procedure and follow-up, with informed consent.
Exclusion Criteria:
- Intra bony lesions (e.g. Cysts) or infections(e.g.abcess) that may retard the osteotomy healing.
- Medically compromised patients.
- Uncooperative patients.
- Patients with any diseases or taking any medications that compromise bone healing
Sites / Locations
- future university in Egypt, faculty of dentistry

Active Comparator
Anterior maxillary bone augmentation using computer guided autogenous cortical shell technique.
Anterior maxilla bone augmentation using free hand autogenous cortical shell technique.
a patient-specific guide was used to harvest a chin cortical shell which was also prepared and positioned at the (anterior horizontally atrophied maxilla) recipient site using another patient-specific positioning guide.
the horizontally atrophic anterior maxilla was augmented with a cortical shell technique the bone was harvested from the chin without a patient-specific guide.
