[Short and long-term results of bone grafting of the maxillary alveolar process in patients with alveolar ridge cleft].

The purpose of this study: Was to evaluate alveolar bone grafting success using the autograft from the mandibular body, own bone fragments and xenogeneic material.

Material and methods: This study was conducted by Central Research Institute of Dentistry and Maxillofacial Surgery (Moscow, Russia) from 2013 through 2023. Consecutive 128 patients with cleft lip/palate who underwent alveolar bone grafting by one surgeon were included. The median age at alveolar bone graft was 12.7 years (range 7-23 years). Inclusion criteria were unilateral and bilateral cleft lip and alveolus and a computed tomography (CT) scan obtained >8 months (128 patients) and 2-10 years (range 3.2 years, 52 patients) after alveolar bone grafting.

Results: The success rate of surgical intervention was 92.6%. Alveolar bone graft undergoes remodeling but not lysis long-term.

Conclusion: Alveolar bone grafting with mandibular bone proved to be effective and has demonstrated good long-term results. The bone level in the grafted area was satisfactory with no signs of resorption.
