Summary
Dental implants can be successfully placed in severely atrophied mandibles without bone grafting. This approach restores function and aesthetics in patients with severe atrophy.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Periodontology
Background:
- Severe mandibular atrophy presents challenges for dental implant placement.
- Traditional methods involve bone grafting or guided bone regeneration.
- These techniques aim to restore bone volume for implant support.
Purpose of the Study:
- To evaluate the feasibility of placing dental implants in severely atrophied mandibles without bone augmentation.
- To assess the long-term outcomes of such implant placements.
Main Methods:
- Twenty-four implants were placed in the anterior sector and on the internal oblique line of six patients with severe mandibular atrophy.
- Patients received implant-supported prostheses.
- A 10-year monitoring period was established.
Main Results:
- All patients achieved successful prosthetic rehabilitation after 12 months.
- Mean marginal bone loss was minimal (+0.11 mm ± 0.53).
- Posterior implants showed slightly less bone loss (+0.06 mm ± 0.48) than anterior implants (+0.14 mm ± 0.57).
Conclusions:
- Dental implants can be effectively placed in the anterior zone and on the internal oblique line in cases of severe mandibular atrophy.
- Adapted implant diameter and length allow for successful prosthetic rehabilitation.
- This single-stage procedure restores phonetic, masticatory, and aesthetic functions with minimal morbidity.
