The All-on-4® approach is designed around efficiency and predictability: by placing four dental implants in strategic positions, a full-arch prosthesis can be attached the same day. This method reduces the number of surgeries and shortens the time between extractions and a functional set of teeth, so patients can leave the office with improved chewing ability and an appearance that immediately restores confidence.
Precision planning is the foundation of a successful All-on-4® restoration. Before any procedure, we review imaging and medical history to map bone structure and identify the best implant sites. That advanced planning helps the surgical team place implants at optimal angles and depths, creating a stable platform for the temporary prosthesis that will carry patients through the healing phase.
For many people who are tired of removable dentures or facing full-arch tooth loss, the ability to walk out with teeth the same day is life-changing. The immediate provisional prosthesis restores basic function and esthetics while the implants integrate with the bone — a process that establishes the long-term foundation for the final restoration.
All-on-4® combines anatomic insight with implant biomechanics. Instead of placing many implants in line with the ridge, the posterior implants are tilted to make use of denser bone farther back in the jaw. This tilting reduces the need for bone grafts and provides better support for the arch with fewer implants, while still delivering the stability needed for comfortable chewing.
Implant components and prosthetic design are matched to each patient’s unique anatomy. The restorative team considers jaw relationships, bite forces, and esthetic requirements when shaping the provisional prosthesis. That collaborative approach helps reduce adjustments after surgery and keeps recovery smoother for patients as they transition to their permanent arch.
Because the method focuses on maximizing support from a limited number of implants, careful surgical execution and prosthetic follow-through are essential. When these elements are coordinated, All-on-4® can offer predictable function and longevity that align with modern implant dentistry standards.
Initial visits center on thorough evaluation and communication. We discuss medical history, oral health goals, and expectations, then obtain diagnostic imaging to build a treatment plan tailored to the individual. Patients receive clear explanations about the surgical sequence and the temporary prosthesis they’ll receive on the day of treatment.
On the day of the procedure, implant placement and immediate provisionalization are performed in a controlled, efficient manner. Local anesthesia and, when appropriate, sedation are used to ensure patient comfort. The provisional arch is attached to the implants once primary stability is achieved, providing immediate function and a finished appearance.
Healing and follow-up visits focus on monitoring integration and fine-tuning the provisional prosthesis for comfort and function. After a healing interval, the final prosthesis is fabricated and secured. This definitive restoration is designed to match the patient’s facial proportions and functional needs so the new arch performs reliably for years.
Restoring a full arch with All-on-4® reestablishes chewing efficiency, enabling patients to enjoy a broader variety of foods. Improved oral function contributes to nutritional well-being, and many patients report greater ease speaking and smiling with confidence. Because the prosthesis is fixed to implants, the experience is often far more comfortable than dealing with removable dentures.
Implant-supported arches also help preserve jawbone by transmitting functional forces through the implants into the bone, which can slow resorption compared with teeth that are missing. Maintaining bone volume is important for long-term facial support and helps sustain a natural appearance over time.
Finally, the streamlined nature of All-on-4® — fewer implants and a consolidated treatment pathway — makes it a practical option for many people seeking a long-term, fixed solution. The approach emphasizes durability, function, and a quality of life that aligns with patients’ daily needs.
Good candidates for All-on-4® are generally those facing loss of most or all teeth in an arch, or who already wear unstable dentures and want a fixed alternative. However, candidacy is established through comprehensive evaluation rather than assumptions: bone quality, general health, and personal expectations all play a role in determining the safest, most effective plan.
Treatment is individualized. If supplemental procedures are necessary, such as minor bone grafting or soft-tissue management, we explain how those steps fit into the overall timeline. The goal is to align clinical needs with the patient’s lifestyle and priorities while maintaining predictable outcomes throughout the process.
Throughout care, our clinical team emphasizes clear communication and evidence-based decision-making. At the office of ProSmiles OC, we combine clinical expertise with modern surgical and prosthetic techniques to create treatment plans that respect each patient’s anatomy and goals.
In summary, the All-on-4® method offers a reliable, science-driven route to restoring a full arch of teeth with the possibility of same-day provisionalization, improved function, and long-term stability.

The All-on-4 treatment concept offers a fixed and permanent alternative to removable dentures. Unlike dentures, All-on-4 does not rely on messy dental adhesives or natural suction to hold your new set of teeth in place. With All-on-4, your replacement teeth are permanently secured by dental implants, giving you a smile that looks not only great but also feels secure and stable. You'll feel comfortable and confident as you speak, smile, and chew with ease.
While traditional full arch implants also achieve outstanding results of care, the All-On-4 treatment concept does not involve bone grafting and requires fewer implants to support a full set of teeth. With just four strategically placed dental implants needed to support an entire set of upper or lower teeth, the All-on-4 treatment concept offers a cost-effective and satisfying solution for rebuilding a complete smile. Thanks to this remarkable method of care, patients can experience the satisfaction of having teeth placed the same day as surgery. This key feature allows patients to smile and function with confidence until healing is complete and the permanent restorations installed.
Once it's been determined that you're a candidate for treatment with All-on-4, the process of treatment planning and designing your new smile begins. 3D diagnostic records provide the detailed information required to determine the exact positions of the four supporting dental implants. Then, on the day of surgery, we'll remove any remaining teeth, place the 4 implants, and insert a set of attractive, sturdy, and functional set of temporary teeth. With All-on-4, temporary teeth can be placed right away with a customized, permanent set to follow once the implants become fully integrated with the surrounding bone.
With All-on-4, temporary teeth can be placed right away with a customized, permanent set to follow within just a few months after the implants become fully integrated with the surrounding bone.
Thanks to All-on-4, patients enjoy permanent teeth that look, feel, and function just like real teeth. And with a patient satisfaction rate that exceeds 95%, the All-on-4 treatment concept restores your smile, your confidence, and allows you to enjoy once again the foods you love!

Our office will demonstrate the most effective methods of oral hygiene and answer all your questions as to how to care for your new smile.
All-on-4® is a full-arch tooth replacement protocol that secures a prosthetic arch to four strategically placed dental implants. Unlike removable dentures, the prosthesis is fixed to implants and does not rely on adhesives or suction to stay in place. This approach is designed to restore chewing function and esthetics with a streamlined surgical and restorative pathway.
The concept uses posterior implant angulation to make the most of available bone and reduce the need for extensive grafting. Because the implants support a fixed provisional prosthesis, patients often receive immediate function on the day of surgery when primary stability is achieved. The goal is to provide a predictable foundation for a durable definitive restoration after healing.
Good candidates are typically people who are missing most or all teeth in an arch or who wear unstable removable dentures and want a fixed alternative. Candidacy depends on a comprehensive clinical evaluation that includes medical history, dental examination and imaging to assess bone quality and oral health. Factors such as systemic health, smoking status and parafunctional habits are also considered when determining suitability.
Age alone is not a limiting factor; rather, the overall health of the patient and the condition of the jawbone guide recommendations. If bone volume is limited in certain areas, tilted posterior implants may often avoid the need for extensive grafting. When additional procedures are required, the treatment plan is tailored to the patient’s clinical needs and expectations.
During the initial consultation we review your medical and dental history, discuss your goals and obtain diagnostic imaging such as cone beam computed tomography to map bone anatomy. Digital planning tools and surgical guides are used to determine ideal implant positions and to design the provisional prosthesis that can be delivered at the time of surgery. Clear communication about the sequence of care, expected outcomes and post-operative requirements is part of the planning phase.
At ProSmiles OC the treatment team coordinates surgical and restorative planning so the provisional arch fits the patient’s functional and esthetic needs. This collaboration reduces surprises on the day of treatment and helps streamline the transition from temporary to final prosthesis. Patients receive instructions about pre-operative preparation and what to expect during the surgical visit.
On the day of surgery the clinical team administers local anesthesia and, when appropriate, sedation to ensure patient comfort. Teeth are extracted if necessary, implants are placed according to the preoperative plan and a provisional prosthesis is attached when implants exhibit sufficient primary stability. The procedure is performed in a controlled, sterile environment with close attention to soft-tissue management and implant positioning.
After the provisional prosthesis is secured the team confirms occlusion and makes any necessary adjustments for comfort and function. Patients receive post-operative care instructions covering oral hygiene, medications and dietary recommendations for the initial healing period. Follow-up appointments are scheduled to monitor integration and to refine the provisional as healing progresses.
Initial recovery typically involves mild-to-moderate swelling and discomfort that can be managed with prescribed or over-the-counter analgesics and cold packs. A soft diet is recommended during the early healing phase while the implants integrate with the jawbone, and patients are advised on gentle oral hygiene techniques to protect the surgical sites. Most patients return to normal daily activities within a few days, though strenuous exercise should be avoided for a limited period.
Osseointegration—the process by which bone bonds to the implant surface—usually takes several months and is monitored through scheduled follow-ups. During this time the provisional prosthesis provides function and esthetics while the bone matures around the implants. Once integration is confirmed, the definitive restoration is fabricated and secured for long-term use.
Immediate provisionalization refers to attaching a temporary fixed prosthesis to the implants on the same day as placement when primary stability is achieved. This provisional arch restores basic chewing function and esthetics while the bone heals around the implants, allowing patients to leave the office with a functional smile. The provisional is designed to protect the implants and to be adjusted as needed during the healing phase.
Primary stability is a critical requirement; if implants do not meet the stability threshold, the team may delay provisionalization until integration progresses. The provisional prosthesis is not the final restoration and is intended to be replaced by a definitive prosthesis once healing is complete. Throughout the provisional phase the clinician monitors fit, occlusion and tissue response to guide the final restorative design.
An implant-supported full-arch restoration can restore efficient chewing, improve speech and provide a fixed solution that does not require nightly removal like conventional dentures. By reestablishing functional load through the implants, the approach helps support jawbone health and facial structures over time. The fixed nature of the prosthesis often leads to increased comfort and predictable daily function compared with unstable removable options.
Long-term success depends on proper maintenance, routine dental care and periodic professional evaluations to check implants and prosthetic components. With careful oral hygiene and regular follow-up, implant-supported arches can provide stable function and esthetics for many years. Clinicians design definitive prostheses to balance durability with the patient’s anatomic and functional needs.
Some patients require supplemental procedures to optimize implant outcomes, although the All-on-4® concept often minimizes the need for extensive grafting by using angled posterior implants. When bone deficiencies or soft-tissue issues are present, targeted bone grafts, minor ridge augmentation or soft-tissue management can improve implant support and esthetic results. The need for these procedures is determined during the diagnostic phase and is explained as part of the treatment plan.
Sinus considerations in the upper jaw or localized bone deficits may require specific interventions to create a stable environment for implants. When additional steps are necessary they are sequenced to align with the overall goals and timeline, and the restorative plan is adjusted accordingly. The clinical team prioritizes predictable outcomes and long-term function when recommending adjunctive procedures.
Dental implants transmit functional forces into the jawbone during chewing, which stimulates bone maintenance and helps slow the resorption that occurs when teeth are missing. Removable dentures rest on soft tissues and do not provide the same mechanical stimulus to the underlying bone, which can lead to progressive bone loss over time. By preserving bone volume, implants contribute to long-term facial support and help maintain a natural appearance.
Maintaining bone also creates a more stable foundation for prosthetic teeth and can reduce the need for future reconstructive procedures. The All-on-4® design seeks to maximize this benefit by positioning implants to engage denser bone where possible. Regular follow-up allows the clinician to monitor bone levels and intervene if changes are detected.
Personalized planning begins with a detailed clinical examination, three-dimensional imaging and a review of the patient’s medical history and goals. The restorative and surgical teams collaborate to determine implant positions, prosthetic design and the timing of provisionalization to match the patient’s anatomy and lifestyle. Individual factors such as bite relationships, lip support and esthetic expectations guide the design of the definitive prosthesis.
At ProSmiles OC Dr. Ivan Ho and the clinical team tailor each plan to prioritize predictable function and long-term health while explaining options clearly to the patient. Follow-up care and maintenance protocols are customized based on the patient’s oral hygiene habits and clinical findings to support lasting success. This individualized approach helps ensure that the final restoration meets both functional and esthetic objectives.
