What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.

Summary

This study tested whether a custom 3D-printed surgical guide helps dentists place bone grafts more accurately in the upper jaw compared to doing it free-hand. Thirty people with thin jawbones received bone taken from their chin. The main goal was to measure how much bone width and height were gained, as seen on CT scans. The study is complete and aims to improve dental implant success.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * • Anterior maxilla with horizontal deficient alveolar ridge that is from 2 to 4 mm measured from the crest of the alveolar ridge buccolingually, combined with vertical deficiency. * Patients free from any systemic conditions and bone metabolism diseases that might interfere with the surgical intervention, soft tissue or hard tissue healing. * Both genders males and females will be included * Normal vertical dimension with normal inter-arch space Exclusion Criteria: * Intra-bony lesions (e.g. cysts) or infections (e.g. abscess) that may retard the osteotomy healing. * 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 females. * Immunosuppressed or immunocompromised * Heavy smokers * Patients undergo medication interfere with bone healing
