Mandibular reconstruction using single piece zygomatic implant in conjunction with a reinforcing Fibular Graft Union: A case report

Bengani A. Management of mandibular nonunion fracture with single-piece implant - A case report

Rationale:

This paper presents the treatment of noninfected hypertrophic, horse hoof nonunion edentulous mandible accompanied with a Luhr class fracture.

Patient Concerns:

The patient reported with complaints of pain and an unstable lower denture at the right side of the lower jaw post mandibular fracture.

Diagnosis:

Upon inspection and post cone-beam computed tomography, it was determined that it was a case of a noninfected hypertrophic, horse hoof nonunion edentulous mandible with Luhr class 1 fracture.

Treatment:

The clinicians in this study treated the fracture with single-piece corticobasal jaw implants successfully with 10 BECES^® corticobasal single-piece jaw implants in the maxilla by engaging double pterygoids bilaterally and eight implants in the mandible.

Outcomes:

After two years, complete unification of the fracture line and callus adaptation was observed on a panoramic radiograph.

Take-away Lessons:

The authors propose a new treatment option for the correction of nonunion mandibular fracture.

A practical approach to orofacial rehabilitation in a patient after inferior maxillectomy and rhinectomy with mono framework construction supported on a zygomatic implant placed in the glabella: a case report

Background

In the field of craniofacial tumor surgery, an adequately performed excision, despite being a life-saving procedure, is only a first step to successful treatment. During such a procedure, the main goal is to completely remove the lesion, paying less attention to factors contributing to future rehabilitation possibilities. One ty 2of the possibilities for prosthetic rehabilitation of such cases is utilizing one-piece implants with bicortical anchorage.

Case presentation

This case report presents a case of a 48-year-old patient with oral squamous cell carcinoma (OSCC). The treatment protocol consisted of radical surgery to remove the tumor, and intraoral and extraoral rehabilitation with a single framework prosthesis anchored with one-piece implants. Moreover, the intraoral stomatognathic deformity was corrected with a fixed implant-retained prosthesis, and the extraoral defect was covered with a removable epithesis.

Conclusions

The use of one-piece implants with bicortical anchorage may be an additional tool in reconstructing maxillofacial defects. Properly executed treatment may improve the esthetics, speech, masticatory function, muscle support, and the overall quality of life of patients with extensive defects in the maxillofacial region.

Immediate rehabilitation of a rheumatoid arthritis patient with single-piece implants

INTRODUCTION AND IMPORTANCE

The aim of this article is to report the long-term outcome of full mouth rehabilitation with single piece, smooth surface implants following immediate loading protocol on a patient suffering with RA and severe unilateral condylar resorption.

CASE PRESENTATION

Here, we present a challenging case of a patient suffering from Rheumatoid Arthritis who was stabilized and completed successfully with a 4 year follow-up period. Prosthetic management optimized the inter-occlusal relationship to maintain both function and esthetic integrity. Single piece implants are designed to engage and take support from the cortical bone low in metabolic activities thus promoting the force transmission through apical threads that are engaged in the cortical bone.

DISCUSSION

Rheumatoid Arthritis [RA] is an auto-immune inflammatory condition in which the inflamed and hypertrophic synovial membrane grows into the articulation surfaces. The Temporomandibular Joints [TM] are frequently involved in rheumatoid arthritis. According to the literature on RA, due to frequent periodontitis, decreased salivary secretion, medication, as well as decrease in bone regenerative potential, RA is often considered as a relative contraindication in the use of implants. Atrophic jaws and cases with comorbidities like osteoporosis, diabetes, rheumatoid arthritis, periodontally infected cases are restored with high success by single piece smooth surface.

CONCLUSION

To the best of our knowledge, this may be the first case of immediate functional loading by bi-cortical single piece implants.
