Aim: Few clinical studies have reported the use of implant supported dental prosthesis for the management of posttraumatic dentoalveolar defects sustained during maxillofacial injuries. This is a presentation of our experience of such patients with the view of adding to the evidence on the subject matter.
Materials and Methods: This is retrospective study of patients seen at Cedarcrest Hospitals and QH Specialist Dental Clinics and Research Centre, in Abuja, over a period of nine years (2013 to 2022). Following standard maxillofacial fracture management, dentoalveolar defects were rehabilitated with implant supported prosthesis. Information extracted from the case files included demographics, case history, associated injuries, number of missing teeth and record of implant treatment done. Data obtained were analysed with SPSS version 20.
Results: There were 19 patients with 13 (68.4%) male and 6 (31.6%) female. Gunshot was the cause of injuries in 9 (47.4/%) patients, Road Traffic Crashes in 8 (42.1%) and fall from a height in 2 (10.5%). Associated injuries sustained included soft tissue in 17 (90.0%) patients and fractures of the following bones: maxillary 11 (57.9%), mandibular 5(26.1%), orbital 3 (15.8%) and zygomatic bone in 1(5.3%) patient. Implant rehabilitation was done using 92 implants for a total of 119 missing teeth. Augmentative surgery achieved with autologous bone grafts in 4 (21.1%) patients and synthetic bone grafts in 13 (78.9%) patients. Rehabilitation was achieved with cemented crowns and bridges in most cases and ball retained removable denture in 2 (10.5%) patients. Implant survival rate of 98.9% and crown survival rate of 98.3% was recorded with a follow-up of 50.6 +26.8. months.
Conclusion: Early implant supported rehabilitation of post-traumatic dentoalveolar defects using osteointegrated implants and bone augmentation was successful with few complications, holistic planning at the onset of management is key.
Clinical Significance: This article is an experience of holistic implant management of patients that sustained dentoalveolar defects in addition to maxillofacial injuries. It highlights the peculiarities of immediate management as well as its advantages and challenges. It will therefore provide a knowledge base that many clinicians may learn from.
