Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 20 participants

Brief Summary

Horizontal ridge augmentation using either cortical bone plate technique or cortico-cancellous block graft was the aim of the study. Bone quality was analyzed histomorphomterically, and horizontal dimensional changes were assessed using CBCT.

Conditions

Horizontal Atrophy of Edentulous Alveolar Ridge

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Cortical bone plate

A cortical plate was harvested from the external oblique ridge and split in half. Then one plate was fixed at a distance from the atrophied ridge and autogenous bone chips were used to fill the gap between the plate and the ridge.

Group Type: EXPERIMENTAL

Split-block technique

Intervention Type: PROCEDURE

Horizontal ridge augmentation using the split-block technique where a cortical bone plate harvested from the external oblique ridge was split in half and fixed at a distance from the atrophied ridge. Then autogenous bone chips were packed in the gap between the plate and the ridge.

Cortico-cancellous block graft

A cortico-cancellous block graft was harvested from the symphysis of the mandible and fixed to the atrophied ridge.

Group Type: ACTIVE_COMPARATOR

Cortico-cancellous block graft

Intervention Type: PROCEDURE

Horizontal ridge augmentation using a cortico-cancellous block harvested from the chin of the mandible.

Interventions
