Introduction:
A dental trauma that leads to tooth fracture or significant damage can be a challenging situation, both for the patient and the treating dentist. When it occurs in a previously treated tooth, such as one that has undergone a root canal treatment (RCT), the prognosis can be uncertain. In this case study, we discuss the management of a patient with a horizontal root fracture in the upper front tooth (tooth #12) and the successful use of an immediate dental implant followed by a screw-retained crown to restore function and aesthetics.
Patient Presentation:
A 32-year-old patient presented with a complaint of pain in the upper front tooth (right maxillary central incisor, tooth #12) for the past 10 days. The patient had a history of root canal treatment (RCT) performed on tooth #12 previously. There were no significant medical conditions or history that would affect the treatment plan. Upon clinical examination, the tooth exhibited grade II mobility, and the patient experienced discomfort when applying pressure on the tooth.
Clinical Findings:
Given the symptoms of pain and mobility in the treated tooth, further diagnostic workup was necessary. A panoramic radiograph (OPG) and an intraoral periapical radiograph (IOPAR) were recommended. The radiographs revealed a horizontal root fracture in tooth #12. A horizontal root fracture is a serious condition that typically results from trauma and often requires tooth extraction if the fracture compromises the tooth’s stability and function.
Diagnosis:
The diagnosis of a horizontal root fracture in tooth #12 was confirmed. Given that the tooth had already undergone RCT, the fracture made the tooth non-restorable. The patient’s complaint of pain and increased mobility were directly linked to the fractured root.
Treatment Plan: After discussing the options with the patient, the recommended treatment plan included:
- Extraction of the compromised tooth (#12).
- Immediate placement of a dental implant to restore the function and aesthetics of the tooth.
- Cone Beam Computed Tomography (CBCT) to assess the bone structure for optimal implant placement.
- A screw-retained crown would be placed after 3 months, once the implant had successfully integrated into the bone.
Treatment Performed:
The treatment was carried out under local anaesthesia. The first step involved the careful extraction of tooth #12, taking special care to preserve the surrounding tissues and bone structure. Once the tooth was extracted, an immediate dental implant was placed in the prepared site. The decision to place the implant immediately was based on the patient’s healthy bone structure and the favourable condition of the extraction site.
The use of a CBCT scan before the implant placement ensured that the bone density and quality were ideal for immediate implant placement. The procedure went smoothly, and the patient was given post-operative care instructions, including pain management and instructions for oral hygiene to promote healing.
Post-Treatment and Healing:
After the implant placement, the patient was scheduled for regular follow-up appointments to monitor the healing process. The healing period typically lasts about 3 months, during which the implant undergoes osseointegration (the process by which the implant fuses with the surrounding bone).
Placement of Screw-Retained Crown:
After 3 months, when the implant had fully integrated, the patient returned for the placement of the final restoration. A screw-retained crown was chosen for this case due to its ease of maintenance and durability. The crown was carefully crafted to match the natural appearance of the adjacent teeth, restoring both the function and aesthetics of the smile.
The crown was securely attached to the implant, and the patient was able to resume normal chewing and speaking functions without discomfort.
Conclusion:
This case demonstrates the importance of proper diagnosis and treatment planning when dealing with a fractured tooth, especially one that has already undergone root canal therapy. The combination of immediate implant placement and a screw-retained crown restoration proved to be an effective solution for this patient, offering a functional and aesthetic outcome.
Why Immediate Implant and Screw-Retained Crown?
- Immediate Implant Placement: Placing the implant immediately after tooth extraction helps preserve the bone structure and reduces the overall treatment time. It also avoids the need for bone grafting, making it a more predictable and efficient option.
- Screw-Retained Crown: This type of crown is preferred for its ease of removal and maintenance. If the crown ever requires adjustment or replacement, it can be easily removed by the dentist. Additionally, screw-retained crowns are more stable and durable than other types of crowns.
- Enhanced Aesthetics and Function: The immediate implant and crown restoration helped the patient regain not only the function of the tooth but also its appearance. The front teeth are critical for the smile’s aesthetics, and restoring them properly is essential for the patient’s self-esteem.
Final Thoughts:
This case highlights how modern dental techniques, including immediate implants and screw-retained crowns, offer patients a rapid and effective solution to dental trauma. By choosing the appropriate treatment plan based on diagnostic findings, dentists can provide long-lasting, functional, and aesthetically pleasing results. If you have a fractured or compromised tooth, it’s important to seek prompt dental care to explore all your restoration options.
