Comparison Between Different Horizontal Ridge Augmentation Techniques

Horizontal Ridge Augmentation Using Decompression Technique Versus Ridge Splitting in Atrophic Posterior Mandibular Ridge With Simultaneous Implant Placement

Sixteen patients were selected from the Outpatient Clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University for replacement of missed single tooth / teeth in posterior atrophic mandible by dental implant.

Patients' grouping:

Patients were divided randomly into two equal uniform groups as follow:

Group I:

Eight implants were placed in patients of missing single tooth / teeth in posterior mandible with subsequent horizontal ridge augmentation by decompression technique.

Group II:

Eight implants were placed in patients of missing single tooth / teeth in posterior mandible with subsequent horizontal ridge augmentation by ridge splitting technique using piezosurgery.

All patients were evaluated clinically and radiographically at regular time interval immediately, 6 and 12 months after surgery.

Inclusion Criteria:

• Patient's cooperation, motivation and good oral hygiene.
• Patient medically free from systemic diseases that absolutely contraindicate implant surgery.
• Moderately atrophic posterior mandible (horizontal alveolar dimension is not more than 4 mm at the crest), with minimum 10 mm vertical height.
• Patients prepared to comply with the follow-up and maintenance programme.
• Free from history of bruxism / parafunctional habits.

Exclusion Criteria:

• Patients with local pathological disease such as cyst, tumor at the planned surgical site.
• Pregnant patients.
