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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: group 1; Eight implants were placed in patients of missing single tooth / teeth in posterior mandible with subsequent horizontal ridge augmentation by decompression technique.	Procedure: horizontal ridge augmentation by decompression technique.; Instead of a cover screw, a 2-mm healing abutment was used after implant insertion
Experimental: group 2; 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.	Procedure: horizontal ridge augmentation by ridge splitting technique using piezosurgery.; horizontal ridge augmentation was done using piezosurgery tips and bone expanders

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Alveolar ridge width	The ridge width was measured on the cross section view at different time interval from the outer surface of the buccal bone to the outer surface of the lingual bone perpendicular to the line marking the long axis of the implant at implant platform. Changes in alveolar ridge width was measured by subtracting ridge width value after 6 and 12 months from immediate postoperative.	12 months
