Robot vs. surgeon: which builds better jawbone?
NCT ID NCT06195761
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using a computer guide makes jawbone-building surgery more accurate than the traditional free-hand method. About 18 adults with narrow jawbones in the back of the lower jaw will take part. Researchers will compare the two techniques using 3D scans to see which one adds bone more precisely.

Inclusion Criteria: * posterior mandible with horizontal deficient alveolar ridge that is from 2 to 4 mm measured from the crest of the alveolar ridge buccolingually * Age range from 25-55 years. No sex predilection. * Patients free from any systemic conditions and bone metabolism diseases that might interfere with the surgical intervention, soft tissue or hard tissue healing. * Patients of adequate alveolar bone width. * Both genders males and females will be included * Normal vertical dimension with normal inter-arch space. The minimum number of missing teeth in the posterior mandible alveolar ridge is two adjacent anterior teeth Exclusion Criteria: * Intra-bony lesions (e.g. cysts) or infections (e.g. abscess) that may retard the osteotomy healing. * Previous grafting procedures in the edentulous area. * General contraindications to implant surgery. * Subjected to irradiation in the head and neck area less than 1 year before implantation. * Untreated periodontitis. * Poor oral hygiene and motivation. * Uncontrolled diabetes. * Pregnant or nursing. * Immunosuppressed or immunocompromised * Heavy smokers * Patients undergo medication interfere with bone healing
