Summary

This prospective controlled clinical study evaluates the effectiveness of adding bone graft or dentin graft material during the split crest (alveolar ridge splitting) procedure for horizontal ridge augmentation with simultaneous implant placement.

The study includes patients with narrow alveolar ridges requiring implant-supported rehabilitation. Participants are divided into three groups: split crest without grafting, split crest with bone graft, and split crest with dentin graft. The aim is to determine whether the addition of graft material to the osteotomy gap improves bone width, bone density, and primary implant stability compared to the split crest technique alone.

Clinical and radiographic assessments are performed using cone-beam computed tomography (CBCT) and implant stability measurements (ISQ values) before surgery, immediately after implant placement, and three months postoperatively. All patients are monitored over a one-year follow-up period to evaluate healing progression and treatment outcomes.

This study seeks to identify the most effective approach for horizontal ridge augmentation and to improve clinical decision-making in implant dentistry. The findings aim to contribute to optimizing surgical protocols, enhancing implant stability, and improving long-term functional outcomes for patients.

Participation is voluntary, and all procedures are conducted in accordance with approved ethical standards and clinical guidelines.

  • Alveolar Bone Resorption
  • Alveolar Bone Grafting
  • Bone Expansion

Interventions

PROCEDURE

Split Crest Technique

A surgical split crest (alveolar ridge splitting) procedure performed to increase horizontal alveolar bone width and enable simultaneous dental implant placement. A controlled osteotomy is created along the crest of the ridge, followed by gradual expansion of the buccal cortical plate to form an osteotomy gap for implant insertion.
