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.

Study Population

In this study, patient follow-up forms and cone-beam computed tomography (CBCT) scans taken during the pre- and postoperative periods were retrospectively reviewed from the archive of the Department of Oral and Maxillofacial Surgery at Kocaeli University Faculty of Dentistry. All procedures had been performed by the same team (B.T. and Z.D.). Among these records, patients who presented with total or partial edentulism in either jaw and received the sausage technique to treat horizontal alveolar bone deficiency were selected for inclusion.

You may qualify if:

• Patients with knife-edge alveolar ridges, classified as Class IV according to the Cawood and Howell classification, who underwent ridge augmentation using the sausage technique
• Patients aged 18 or older with fully developed bone
• Patients who had regular clinical and radiographic follow-up after the procedure, with a minimum follow-up period of six months

You may not qualify if:

• Patients with systemic conditions (such as osteoporosis, cancer, immunosuppression, hyperparathyroidism, or hyperthyroidism) or a history of medications (including intravenous or oral bisphosphonates, immunosuppressants, or chemotherapy) that could interfere with bone healing
• Patients with a history of radiotherapy to the head or neck region
• Patients classified as ASA III or ASA IV
• Patients who were active smokers at the time of surgery
• Patients whose pre- or postoperative CBCT scans were of low image quality or affected by artefacts
