Horizontal Ridge Augmentation Using Sausage Technique: A Retrospective Study

Completed

• Conditions: Alveolar Bone Grafting; Guided Bone Regeneration; Bone Gain

• Registration Number: NCT07041398
• Lead Sponsor: Kocaeli University

Brief Summary

This retrospective study investigates the outcomes of the sausage technique, a contemporary modification of guided bone regeneration (GBR), for the augmentation of severely horizontally deficient alveolar ridges (\<4 mm width). The technique, originally introduced by Urban and colleagues, uses multiple fixation pins to enhance membrane stability and maintain graft volume through a tension dome effect.

In this study, a total of 23 patients underwent horizontal ridge augmentation using the sausage technique, with bone measurements assessed at 2, 4, and 6 mm apical to the crest using CBCT imaging at preoperative (T0), early postoperative (T1), and late postoperative (T2) stages. The study quantitatively analyzed both horizontal bone gain (T2-T0) and bone resorption (T1-T2) during the healing period.
