The Challenging Case of a Crown-Root Fracture
At Station Road Dental Aldergrove, we take pride in our ability to handle complex dental cases with the utmost care and expertise. Today, we’d like to share the story of a patient who presented with a crown-root fracture that was encroaching on the biological width – a delicate situation that required a tailored treatment approach.
Mrs. Samantha Wilkins, a 55-year-old patient, came to our clinic with a history of sensitive and painful symptoms on her upper right central incisor. Upon examination, our dentists discovered a horizontal crown-root fracture that extended below the gumline, dangerously close to the biological width. This sensitive area, where the tooth meets the surrounding gum tissue, is crucial for maintaining healthy periodontal (gum) conditions.
Understanding Crown-Root Fractures
A crown-root fracture is a type of dental injury where the tooth’s crown (visible part) and root (embedded part) are both broken, often in a horizontal pattern. These types of fractures can be particularly problematic, as they can compromise the tooth’s structural integrity and threaten the surrounding periodontal tissues.
In Mrs. Wilkins’ case, the crown-root fracture was especially concerning because it was encroaching on the biological width – the delicate zone between the top of the alveolar bone (the bone that supports the teeth) and the bottom of the gum tissue. Maintaining this space is crucial for preserving the health and stability of the periodontal structures.
Evaluating the Biological Width
The biological width is a critical concept in dentistry, as it represents the minimum vertical distance required between the gingival margin (gum line) and the alveolar crest (the top of the supporting bone). This area is typically 2-3 millimeters in height and is essential for maintaining proper periodontal function and esthetics.
When a crown-root fracture encroaches on the biological width, it can disrupt the delicate balance of the periodontal tissues, leading to potential issues such as:
- Gingival inflammation and recession
- Alveolar bone loss
- Increased risk of periodontal disease
- Compromised tooth stability and longevity
In Mrs. Wilkins’ case, our dentists carefully evaluated the extent of the crown-root fracture and its proximity to the biological width using a combination of clinical examination and radiographic imaging. This comprehensive assessment was crucial in determining the appropriate treatment plan to address the complex situation.
Developing a Treatment Plan
After a thorough evaluation, our dentists at Station Road Dental Aldergrove developed a comprehensive treatment plan to manage Mrs. Wilkins’ crown-root fracture while preserving the biological width and her periodontal health.
The treatment plan involved the following steps:
-
Provisional Restoration: To address the immediate concerns and alleviate Mrs. Wilkins’ symptoms, our dentists placed a temporary composite resin restoration on the affected tooth. This allowed them to seal the fracture, protect the pulp (inner tooth nerve), and provide relief from sensitivity and pain.
-
Surgical Crown Lengthening: Given the location of the crown-root fracture below the gingival margin, our periodontist performed a surgical crown lengthening procedure. This involved carefully removing a small amount of the alveolar bone and gingival tissue to expose more of the tooth structure and re-establish the proper biological width.
-
Definitive Restoration: After allowing the gingival tissues to heal and stabilize, our dentists proceeded with the final restoration. In Mrs. Wilkins’ case, they opted for a full-coverage crown to provide a durable and long-lasting solution that would protect the remaining tooth structure and maintain the periodontal health.
Throughout the treatment process, our team closely monitored Mrs. Wilkins’ progress, ensuring that the biological width was maintained and the periodontal tissues remained healthy. Regular prophylaxis (professional cleanings) and oral hygiene instructions were also provided to support her overall dental health.
Managing the Outcomes
The successful management of Mrs. Wilkins’ crown-root fracture encroaching the biological width was a testament to the expertise and collaborative approach of our dental team at Station Road Dental Aldergrove.
The surgical crown lengthening procedure allowed our periodontist to reestablish the proper biological width, creating a stable foundation for the final full-coverage crown restoration. This comprehensive treatment approach not only addressed the immediate issue but also ensured the long-term periodontal health and stability of the affected tooth.
During the follow-up visits, our dentists carefully monitored the gingival healing, the alveolar bone levels, and the overall periodontal condition. Mrs. Wilkins’ dental hygiene regimen was reinforced, and she was encouraged to maintain regular prophylaxis appointments to sustain the positive treatment outcomes.
The Importance of Proactive Dental Care
The case of Mrs. Wilkins highlights the importance of proactive dental care and the need for prompt attention to complex dental issues. By addressing the crown-root fracture and the biological width concerns in a timely manner, our team at Station Road Dental Aldergrove was able to preserve the affected tooth, maintain the periodontal health, and provide Mrs. Wilkins with a comfortable and functional long-term solution.
