Crestal Bone Level After Allogenic Bone Ring With Simultaneous Dental Implant Placement

Evaluation Of Crestal Bone Level After Alveolar Bone Augmentation of Atrophied Posterior Mandibular Region Using Allogenic Bone Rings Vs. Autogenous Bone Rings With Simultaneous Dental Implant Placement (A Randomized Controlled Clinical Trial)

This trial is aiming to answer a question whether in Patients with severely atrophied, distal mandibular regions, the use of allogenic bone rings with simultaneous dental implants, compared to autogenous bone rings, give successful clinical and radiographic outcomes without donor site morbidity

Inclusion Criteria:

1. Medically free form any systemic diseases that contraindicate the surgical procedures or affect predictable outcomes and non-smoker subjects.
2. Atrophic mandibular distal region requiring vertical augmentation.
3. Good oral hygiene and healthy keratinized mucosa.

Exclusion Criteria:

1. Presence of acute dentoalveolar infection or any pathologic lesions.
2. Totally edentulous patients and patients requiring massive reconstruction and augmentation procedures.
3. Patients with history of previously failed augmentation procedures, or failed implant placement at the intended augmentation region.
