Osseodensification for Narrow Alveolar Ridge Expansion

Yemen30 participantsStarted 2025-02-01

Plain-language summary

This prospective clinical study aims to evaluate the effectiveness of osseodensification in expanding narrow alveolar ridges during dental implant site preparation. Alveolar ridge deficiency is a common clinical challenge that may complicate implant placement. Osseodensification is a minimally invasive drilling technique that preserves and compacts bone rather than removing it, potentially allowing simultaneous ridge expansion and implant placement. In this study, patients presenting with narrow alveolar ridges indicated for dental implant placement will be treated using Densah burs operating in a non-extractive (densifying) mode. Ridge width will be measured directly using standardized Micro Castroviejo bone calipers at three reference levels: at the crestal bone level and at 5mm, at 10 mm apical to the crest. Measurements will be recorded immediately before and immediately after osseodensification. The primary objective is to assess the dimensional changes in ridge width achieved through osseodensification without the use of additional ridge augmentation procedures. The study focuses solely on within-subject comparison (pre- and post-expansion measurements) and does not compare this technique to other ridge expansion methods. The results are expected to provide clinical evidence regarding the amount of horizontal ridge expansion achievable using osseodensification and its applicability in managing narrow alveolar ridges for implant therapy.

Inclusion Criteria: * Patients aged 18 years or older, including both genders. * Healed edentulous sites (short or long spans, single or multiple missing teeth) in maxillary or mandibular arches. * At least 6 months post-extraction period (delayed implant placement). * Alveolar ridge width of 3-8 mm at the crest (buccolingually). * Low-density jaw regions (D1-D5 according to Misch classification). * Presence of ≥ 2 mm trabecular bone core and trabecular-to-cortical bone ratio of ≥ 1:1. * Sufficient vertical dimensions as assessed via CBCT. * Straightforward cases according to SAC classification (Beagle, 2013). * Well-motivated patients willing to attend follow-up visits and maintain good oral hygiene. Exclusion Criteria: * Acute or chronic infection or pathological condition at the proposed implant site. * Severe buccal plate undercut or concavity. * Signs of active infection in the implant zone. * Severe parafunctional habits such as bruxism or clenching. * Heavy smoking (more than 10 cigarettes per day). * Inadequate inter-ridge distance or insufficient vertical height for implant placement. * Use of medications compromising bone healing (e.g., corticosteroids, hormone replacement therapy, or bisphosphonates). * Uncontrolled systemic diseases (e.g., diabetes, immunocompromised states, hyperparathyroidism, or fibrous dysplasia). * History of radiotherapy to the head/neck or chemotherapy within the past 5 years. * Current pregnancy during the surgical procedure.

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?

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.
