The transmandibular implant: a 12-year follow-up study
1Deaconesses Hospital, Department of Oral and Maxillofacial Surgery, Groningen, The Netherlands.
Summary
The transmandibular implant effectively restores function in severely atrophic mandibles, offering a predictable solution for dental prostheses. This clinical study followed 368 patients, with long-term outcomes demonstrating successful rehabilitation.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Reconstructive Dentistry
Background:
- Severely atrophic mandibles pose significant challenges for dental prosthesis rehabilitation.
- Traditional augmentation procedures may offer less predictable outcomes for mandibular reconstruction.
Purpose of the Study:
- To evaluate the efficacy and predictability of the transmandibular implant system for reconstructing severely atrophic mandibles.
- To assess long-term functional restoration and complication rates associated with this implant technique.
Main Methods:
- A clinical study involving 368 patients with a mean mandibular height of 10 mm.
- Comprehensive evaluation using clinical examination, radiography, and patient questionnaires.
- Long-term follow-up, with 185 patients observed for 5+ years and 55 for 10+ years.
Main Results:
- Successful functional restoration was achieved in the majority of patients.
- Removable dentures were fabricated for 350 patients, and fixed bridges for 18.
- Reversible complications (e.g., infection, hyperplasia) were managed effectively without significant long-term tissue damage. Six implants required removal.
Conclusions:
- The transmandibular implant system provides a predictable and successful method for restoring function in severely atrophic mandibles.
- It presents a viable alternative to augmentation procedures for complex mandibular reconstruction cases.
