Comparison of Split Box and Split Bone Block Techniques in Horizontal Ridge Augmentation

NCT07656662 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 31

No results posted yet for this study

Summary

Horizontal alveolar ridge deficiencies may prevent the placement of dental implants and often require bone augmentation procedures before implant treatment. Two techniques commonly used for horizontal ridge augmentation are the Split Box Technique and the Split Bone Block Technique.

This retrospective study included patients treated at Marmara University Faculty of Dentistry between January 2014 and January 2026. Radiographic records were reviewed to evaluate bone gain after augmentation and the stability of the augmented bone during long-term follow-up. Implant survival after prosthetic rehabilitation was also assessed.

The purpose of this study was to compare the long-term outcomes of the Split Box Technique and the Split Bone Block Technique in terms of bone gain, bone stability, and implant survival.

Conditions

  • Horizontal Alveolar Ridge Deficiency

Interventions

PROCEDURE

Split Bone Block Technique

Autogenous horizontal ridge augmentation procedure using cortical bone plates harvested from the mandibular ramus to reconstruct deficient alveolar ridges prior to implant placement.

PROCEDURE

Split Box Technique

Autogenous horizontal ridge augmentation procedure involving mobilization and fixation of a buccal bone segment to increase horizontal ridge width prior to implant placement.
