Horizontal Ridge Augmentation Using Sausage Technique: A Retrospective Study
Turkey (Türkiye)23 participantsStarted 2024-01-02
Plain-language 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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* 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
Exclusion Criteria:
* 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
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
