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 two 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 3-5 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.
