All-on-4®Dental Implants in Tribeca, NYC
A fixed full-arch tooth-replacement approach supported by four strategically planned implants. Digital imaging, surgical planning, provisional teeth when clinical criteria are met, and long-term restorative care are coordinated in one treatment pathway.
All-on-4 may be considered for patients missing most or all teeth in one arch, but candidacy and immediate loading must be confirmed after a clinical and 3D evaluation.

Full-Arch Implant Concept
Understanding the TreatmentExplore the Implant Center↗
What Are All-on-4® Dental Implants?
All-on-4® is a full-arch treatment concept designed for patients who need replacement of most or all teeth in the upper or lower jaw. Four implants support a fixed bridge rather than replacing every missing tooth with a separate implant.
The two posterior implants can be angled up to 45 degrees when appropriate. This can help use available anterior bone, extend support toward the back of the arch, and in some cases reduce the need for bone grafting.
A provisional fixed arch may be attached on the day of surgery when adequate primary stability is achieved. The definitive restoration is planned after the healing phase and may differ in material, fit, bite design, and hygiene access.
Why This Concept Is Used
Potential Advantages of All-on-4 Full-Arch Treatment
The value of All-on-4 is not that it is automatically the best option for everyone. Its advantage is that implant position, prosthetic design, and available bone can be coordinated into a streamlined full-arch treatment when the anatomy and clinical conditions support it.
May Reduce the Need for Bone Grafting
Strategic implant positioning can sometimes avoid a separate grafting procedure, but this depends on bone anatomy, implant stability, and the treatment plan.
Designed for Fixed Function
Unlike removable dentures, the restoration is secured to implants. The shape, bite, hygiene access, and final material are planned around the individual patient.
Candidate Assessment
Who May Be a Candidate for All-on-4?
An All-on-4 consultation is an evaluation, not an automatic treatment recommendation. Full-arch planning starts by determining whether remaining teeth should be preserved, whether four implants are appropriate, and whether another restorative approach would better match your anatomy and goals.
- ✓Multiple failing, missing, or non-restorable teeth in one arch
- ✓Current removable denture wearers seeking a fixed implant-supported option
- ✓Adequate bone volume and quality for planned implant positions
- ✓General and oral health that supports implant surgery and healing
- ✓Ability to maintain daily hygiene and attend long-term maintenance visits
What We Evaluate
01
Bone Anatomy
CBCT imaging can help evaluate available bone, sinus position, nerve anatomy, and potential implant trajectories.
02
Gum Health
Active periodontal disease, inflammation, or infection should be identified and addressed as part of planning.
03
Bite & Prosthetic Space
The team evaluates bite forces, smile line, available restorative space, speech, and the desired final tooth position.
04
Medical History
Medications, smoking history, healing risk, and relevant medical conditions are reviewed before surgical treatment is recommended.
Treatment Journey
How All-on-4 Dental Implant Treatment Works
A strong full-arch result starts before surgery. Diagnostic planning, prosthetic design, surgical placement, healing, and long-term maintenance all influence the final outcome.
Consultation & Full-Arch Evaluation
We review your goals, dental history, existing teeth, gum condition, bite, and previous implant or denture experience.
3D CBCT & Digital Planning
Three-dimensional imaging and digital scans help map anatomy, restorative space, and potential implant positions before surgery.
Personalized Treatment Plan
The plan defines whether teeth need removal, whether grafting is necessary, the implant strategy, provisional restoration, and expected healing sequence.
Implant Placement
Four implants are positioned to support the arch. When adequate stability and clinical criteria are met, a fixed provisional restoration may be placed the same day.
Healing & Osseointegration
During healing, the implants integrate with the surrounding bone. Follow-up visits are used to monitor tissue health, bite, comfort, and hygiene.
Final Full-Arch Restoration
After appropriate healing, the final restoration is designed for fit, function, cleansability, speech, and appearance.
3D Treatment Planning
Why CBCT Imaging Matters for Full-Arch Implants
Bone Mapping
Three-dimensional imaging helps the clinical team evaluate bone volume and anatomy at potential implant sites.
Anatomical Structures
Planning considers the relationship between proposed implants and nearby structures such as the maxillary sinus and nerve pathways.
Prosthetic Planning
Implant placement is coordinated with the planned tooth position, bite, smile line, restorative space, and hygiene access.
Digital Records
Digital scans can help document the arch and support communication between surgical and restorative planning.
Compare Full-Arch Options
All-on-4 vs. Removable Dentures vs. Conventional Full-Arch Implants
These approaches solve different problems. The right choice depends on anatomy, remaining teeth, health, maintenance ability, restorative goals, and the clinical plan.
| Feature | All-on-4® | Removable Dentures | Conventional Full-Arch Implants |
|---|---|---|---|
| Retention | Fixed to implants | Patient-removable | Fixed to multiple implants |
| Typical Support | Four implants per arch | Gums / palate, sometimes implants | Often more than four implants |
| Bone Grafting | May be avoidable in some cases | Usually not required for a conventional denture | May be needed depending on implant positions |
| Provisional Teeth | Same-day provisional may be possible | Immediate dentures may be possible | Depends on stability and treatment design |
| Daily Cleaning | Brush plus cleaning under the bridge | Remove and clean the denture | Brush plus implant-specific interdental care |
Recovery & Maintenance
Care Does Not End on Surgery Day
Full-arch implants require healing, follow-up, home hygiene, and professional maintenance. Your exact instructions should come from the treating clinical team because surgery and restorative designs vary.
First Days
Follow the post-operative instructions provided for eating, oral hygiene, medications, and activity. Contact the office if symptoms feel unusual or worsen.
Healing Phase
The provisional restoration may require bite or fit adjustments while tissues change. Follow-up appointments help monitor healing and implant stability.
Long-Term Maintenance
Implant-supported full arches still require daily plaque control and professional maintenance. The team can show you how to clean around and beneath the restoration.

Patient Knowledge
All-on-4 Dental Implants FAQ
These answers provide general educational information. Your diagnosis, treatment sequence, healing time, and suitability for immediate loading require an individual clinical evaluation.
01What are All-on-4 dental implants?
+
What are All-on-4 dental implants?
All-on-4 is a full-arch implant treatment concept in which four implants support a fixed prosthetic arch. Two posterior implants may be tilted to improve the use of available bone and reduce cantilever length.
02Can I get temporary teeth the same day?
+
Can I get temporary teeth the same day?
In qualifying cases, a fixed provisional restoration may be delivered on the day of implant placement. Immediate loading depends on implant stability, bone conditions, bite forces, and the surgical plan, so it cannot be promised before evaluation.
03Does All-on-4 always avoid bone grafting?
+
Does All-on-4 always avoid bone grafting?
No. The angled implant concept can reduce the need for grafting in many full-arch cases, but some patients still need bone augmentation or a different implant strategy based on their anatomy and treatment goals.
04Who is a candidate for All-on-4?
+
Who is a candidate for All-on-4?
It may be considered for people missing most or all teeth in an arch, people with severely compromised teeth, or denture wearers seeking a fixed option. Candidacy depends on oral health, bone anatomy, medical history, hygiene, and restorative goals.
05What is the difference between the temporary and final All-on-4 bridge?
+
What is the difference between the temporary and final All-on-4 bridge?
A provisional bridge is designed to protect the surgical plan and provide function during healing. After healing and implant integration, the final restoration can be refined for fit, bite, cleansability, material, and esthetics.
06How long does All-on-4 treatment take?
+
How long does All-on-4 treatment take?
The surgical visit is only one part of the process. Consultation, imaging, planning, surgery, healing, follow-up, and fabrication of the final restoration occur over a longer treatment timeline that varies by patient.
07How do I clean an All-on-4 bridge?
+
How do I clean an All-on-4 bridge?
Daily care typically includes brushing the restoration and cleaning beneath the bridge with tools recommended for your design, such as floss threaders, interdental brushes, or an oral irrigator. Professional maintenance remains important.
08What if I have been told I do not have enough bone?
+
What if I have been told I do not have enough bone?
Low bone volume does not automatically determine one treatment. 3D evaluation can help identify whether standard All-on-4 positioning, grafting, additional implants, or another full-arch approach should be considered.
