Single Crowns
A traumatic injury left this patient with a severely fractured and mobile upper front tooth. Because the tooth could no longer be predictably saved, treatment focused on replacing one highly visible tooth while preserving the surrounding smile and minimizing the amount of time the patient would have to go without a front tooth.
A traumatic injury damaged one highly visible front tooth
The patient, a man in his 20s, presented after suffering trauma to the face during an altercation. His face was significantly swollen, and one upper front tooth had visibly shifted downward compared with the neighboring teeth.
The injured tooth was also mobile, showing that the damage extended beyond the visible portion of the tooth. Because the problem involved a front tooth, the patient was understandably concerned about losing it and being left with a noticeable gap.
The fracture had destabilized the tooth and made preservation unpredictable
Clinical examination confirmed significant swelling and abnormal movement of the injured tooth. X-rays showed a fracture that had destabilized the tooth and caused it to move partially out of its normal position.
Because of the extent of the fracture and mobility, preserving the natural tooth was no longer considered predictable. Extraction was necessary.
The goal was to restore a single missing tooth in a highly visible area while keeping the neighboring natural teeth untouched and creating a final crown that blended naturally into the smile.
Same-day implant placement with a custom temporary single crown
The fractured tooth was carefully extracted, and a dental implant was placed immediately into the extraction site.
Dual-zone grafting was performed around the implant to help preserve the surrounding bone and soft-tissue contours. This is especially important in the front of the mouth, where gum shape can have a major influence on how natural the final single crown appears.
Because the implant achieved sufficient stability, a temporary implant abutment and custom temporary crown were placed during the same appointment. The patient was therefore able to leave with a replacement front tooth on the same day the damaged tooth was removed.
After approximately five months of healing and implant integration, the temporary crown was replaced with a custom permanent zirconia implant crown designed to function as one independent replacement tooth and match the surrounding natural teeth as closely as possible.
How a single implant crown can replace one missing front tooth
When only one tooth is lost, treatment does not necessarily need to involve the neighboring teeth. A single implant crown replaces the missing tooth using two primary components: a dental implant placed in the jawbone to replace the root and a custom crown attached above it to recreate the visible tooth.
This can be particularly valuable in the front of the mouth because the replacement crown can be designed independently to match the shape, size, position, and appearance of the surrounding natural teeth.
In selected situations, an implant can be placed immediately after an injured tooth is extracted. If adequate initial stability is achieved, a temporary single crown may also be placed that same day. This immediate provisional crown maintains the appearance of the smile during healing and can help guide the surrounding gum tissue.
Once the implant has integrated with the bone and the tissues have stabilized, the temporary restoration is replaced with the final custom crown.

Questions about single implant crowns
What is a single implant crown?
A single implant crown is used to replace one missing tooth. A dental implant functions as the replacement root, while a custom crown is attached above it to recreate the visible portion of the tooth.
Why couldn't this patient's original front tooth be saved?
The trauma caused a significant fracture and left the tooth mobile and displaced from its normal position. After clinical and X-ray evaluation, the damage was determined to be severe enough that the tooth could not be predictably restored.
Can a front tooth be extracted and replaced with a temporary crown on the same day?
In selected cases, yes. If the extraction site is suitable and the implant achieves adequate initial stability, an implant and temporary crown may be placed during the same appointment.
Is the same-day crown the permanent crown?
No. The initial crown is generally a temporary restoration used while the implant heals. In this case, the temporary crown remained in place for approximately five months before being replaced with the final zirconia crown.
Why is a temporary crown important for a front tooth?
In addition to maintaining appearance, a properly designed temporary crown can help support and shape the surrounding gum tissue while the implant heals. This is especially important in the esthetic zone.
What is dual-zone grafting?
Dual-zone grafting is used during immediate implant placement to help preserve the bone and soft tissues surrounding the extraction site. Maintaining these tissues can be particularly important around a front tooth because gum contours influence the final appearance.
Why did the implant need about five months to heal?
The surrounding bone needs time to integrate with the implant surface. This healing process creates the stable foundation needed to support the permanent crown. Healing time varies based on bone quality, implant stability, anatomy, grafting, and treatment location.
What is a zirconia crown?
Zirconia is a strong ceramic material commonly used for dental crowns. A zirconia implant crown can be customized in its shape, proportions, and appearance to blend with the surrounding smile.
Will a single implant crown look like a natural tooth?
The goal is for it to blend as naturally as possible. The final result depends on implant positioning, available bone and gum tissue, crown design, tooth shape, color, and the relationship between the restoration and neighboring teeth.
Does replacing one tooth with an implant affect the neighboring teeth?
Unlike a traditional tooth-supported bridge, a single implant normally does not require healthy neighboring teeth to be prepared solely to support the replacement tooth. The implant independently supports its own crown.
Can every fractured front tooth receive an immediate implant crown?
No. Immediate implant placement and provisionalization depend on the condition of the extraction site, surrounding bone and gum tissue, infection, implant stability, bite forces, and other clinical factors. Some patients require a staged approach instead.
Need to replace a single damaged or missing tooth?
At Ellui Dental, single-tooth treatment is planned around restoring function while creating a crown that blends naturally with the surrounding smile. A consultation can determine whether a traditional crown, implant-supported crown, or another restorative option is most appropriate for your situation.
