Comparison of Two Expansion Techniques for Horizontal Bone Deficiency

This was a prospective, randomized clinical trial conducted at the Department of Oral and Maxillofacial Surgery, Ege University. Patients exhibiting horizontal bone insufficiency (residual crest width \< 4 mm) in the posterior mandible received dental implants with two techniques: osseodensification or crest split. The investigator compared to clinical and radiological outcomes of these techniques.

Inclusion Criteria: * a residual horizontal alveolar crest width of less than 4 mm * clinical indication for at least two implants * good systemic health Exclusion Criteria: * patients requiring vertical augmentation * tooth extraction prior or peri-surgery * presence of acute local infection or pathology at the operative site * allergy to titanium, anesthetics, or surgical materials * pregnancy or lactation * history of bisphosphonate or antiresorptive use
