The All-on-4 dental implant procedure is a prosthodontic solution for the total rehabilitation of patients with missing teeth, badly broken down teeth, decayed teeth, or teeth compromised by gum disease[1]. It provides a permanent, screw-retained, same-day replacement of teeth[1]. The term "All-on-4," also known as "All-on-Four" and "All-in-Four," signifies that 'all' teeth are supported 'on four' dental implants[1]. This innovative approach involves the rehabilitation of either the edentulous (toothless) or dentate maxilla and/or mandible with a fixed prosthesis by placing four implants in the anterior maxilla, where bone density is higher[1]. These four implants support a fixed prosthesis with 10 to 14 teeth, which is typically placed within 24 hours of surgery[1].
The All-on-4 technique is a revolutionary approach to solving the problem of multiple missing teeth and reconstructing a patient's mouth to restore full function[3]. Losing teeth can occur due to various factors, including accidental impact, advanced tooth decay, or other oral health problems[3]. Regardless of the cause, addressing the issue is crucial to restore the patient's mouth to full function, and All-on-4 is one of the most modern methods to achieve this goal[3].
All-on-4 fixed dentures differ from traditional dentures in several ways[4]. They do not rely on adhesives, do not shift, do not require removal for cleaning, and do not degrade over time[4]. This "soft" implantology solution limits the number of implants placed per jaw while preventing the progressive deterioration of the jawbone that occurs when natural or artificial tooth roots are absent[4]. In addition to providing a natural aesthetic appearance and restoring a genuine smile, All-on-4 dental implants also enable efficient, long-lasting chewing[4]. Gum problems can be resolved before the operation with a gummy smile treatment[4].
The All-on-4 procedure works by placing two implants at an angle in the denser and stronger bone at the front of the jaw[7]. This allows all replacement teeth to be supported on just four implants with one bridge[7]. Consequently, the entire row of teeth is supported by the strongest bone[7].
The All-on-4 dental implant procedure offers numerous benefits, making it a popular choice for individuals seeking a permanent and efficient solution for missing teeth.
-Fixed and Comfortable: Unlike removable dentures, All-on-4 treatment is fixed, providing greater comfort, durability, and aesthetics[4].
-Suitable for Low Bone Mass: The All-on-4 system is suitable for patients with low bone mass, eliminating the need for bone grafting in many cases[4].
-Prevents Bone Degradation: The dental prosthesis is fixed in the bone, preventing bone degradation that can occur in the absence of natural or artificial tooth roots[4].
-Long-lasting: An All-on-4 implant-supported bridge can last over 20 years with proper dental hygiene, regular check-ups, and abstaining from smoking[4].
-Faster Recovery: The All-on-4 implant solution offers a faster and less restrictive recovery due to the limited number of implants[4].
-No Sinus Lift Required: The creation of a bridge surmounted by a false gum does not require pre-implant surgery like a Sinus Lift[4].
-Restored Functionality: All-on-4 dental implants restore the full functioning force of chewing, allowing you to speak and smile confidently, improving your quality of life[5].
Determining whether you are a suitable candidate for All-on-4 dental implants involves a comprehensive evaluation by a prosthodontist[5]. This assessment ensures the best possible outcome for the procedure.
Personalized Treatment Plan
1. Initial Consultation: The process begins with an initial consultation with the prosthodontist to discuss concerns, goals, and personal requirements for All-on-4 dental implants[5].
2. Oral Examination: The prosthodontist conducts a thorough oral examination, inspecting the facial structure, gums, remaining natural teeth, and jawbone[5].
3. X-rays and CT Scan: The prosthodontist takes X-rays of the jaw using a 2D panoramic radiograph and a 3D computerized tomography (3D CT) scan[5]. The coDiagnosTiX software assesses the amount of alveolar bone that supports the tooth root to determine if it is sufficient for implant placements and to identify the location of vital organs and related nerves[5].
4. Treatment Plan: Based on the examination results, the prosthodontist tailors a treatment plan and prepares for the fabrication of a temporary bridge at the digital dental lab[5].
The All-on-4 dental implant procedure is a two-phase surgical process[2]. The first phase involves the surgical placement of four dental implants into the jaw, while the second phase occurs after healing and includes attaching a new abutment to the dental implants and fitting a new set of teeth (denture) to the abutments[2].
Surgery Placement Phase
1. Implant Placement: During the surgical portion of the treatment, the dental surgeon measures and marks the correct natural distance between the top and bottom jaws to ensure proper alignment[3]. The prosthodontist performs the All-on-4 dental implant surgery using CT-guided surgery to guide tooth extraction, drill the gums, and accurately place four dental implants in the designated positions according to the treatment plan, avoiding vital organs and other teeth[5].
2. Implant Angulation: The prosthodontist surgically posts two dental implants in the anterior maxilla at a 90-degree angle and two in the posterior maxilla at a 17-45-degree angle in areas with high alveolar bone density to achieve balance and stability[5]. Bone grafting may be considered for individuals with insufficient alveolar bones to support their tooth roots[5].
3. Alveolectomy: After placing the four dental implants, the prosthodontist performs an alveolectomy to prepare the gums and teeth by circumcising and shaping both the upper and lower jaw bones to ensure the bridge fits snugly[5].
4. Temporary Bridge Placement: A temporary acrylic bridge is placed over the gums and adjusted to fit snugly against the gum, ensuring proper dental occlusion[5]. The abutments are screwed up, and the bridge is firmly attached to ensure secure attachment[5]. This temporary bridge creates balance and stabilization, enables full chewing force, and provides comfort with a new, confident smile[5].
5. Duration: The surgery typically takes approximately 3–4 hours[5].
Denture Attachment Phase
1. Healing Period: A healing period of 2 to 6 months is required to allow optimal bone integration of the implants and healing of the gums[4]. During this time, the patient wears a suitable temporary prosthesis[4].
2. Permanent Denture Attachment: During the second appointment, the dentist inserts the prosthetic arch into the implants, topped by false teeth, with the shade previously chosen in consultation with the patient[4]. The permanent caps are removed, along with any temporary components used in surgery. A new abutment is attached to each of the dental implants, and a new set of customized teeth is fitted to the abutments and held in place by the implants[2]. This second session typically lasts less than an hour[4].
Proper recovery and aftercare are essential for the long-term success of All-on-4 dental implants.
-Post-Surgery Care: Following the implant day, the surgeon restores the gum tissue around the implants and stitches up any openings[8]. The temporary holes are sealed, and the bite pattern is checked and verified[8]. The healing process then begins[8].
-Dietary Considerations: Patients need to wait between three and six months after the implants are fitted before resuming a completely normal diet[4].
-Dental Hygiene: Maintaining impeccable dental hygiene is crucial for the longevity of All-on-4 dental implants[4]. This includes regular brushing, flossing, and check-ups with your dentist.
-Regular Check-ups: Undergoing a check-up and scaling once a year at your dentist's is essential to ensure the continued health and stability of the implants[4].
The long-term success of All-on-4 dental implants depends on several factors, including proper oral hygiene, regular dental check-ups, and lifestyle choices.
-Implant-Supported Bridge Longevity: An All-on-4 implant-supported bridge can last over 20 years with proper care[4].
-Avoiding Smoking: Refraining from smoking is crucial, as smoking can compromise the health of the gums and bone, potentially leading to implant failure[4].
-Maintaining Dental Hygiene: Consistent and thorough dental hygiene practices are essential for preventing infections and maintaining the health of the implants[4].
-Regular Professional Cleanings: Regular professional cleanings help remove plaque and tartar buildup, preventing gum disease and ensuring the longevity of the implants.
The cost of All-on-4 dental implants can vary depending on several factors, including the location of the dental practice, the complexity of the case, and the materials used for the prosthesis.
-Price: Implantology is generally more expensive than removable dentures[4].
-NHS Refund Rate: Implantology is also much less covered by Social Security, as removable prostheses can often be reimbursed at 100% by Assurance Maladie and Mutuelles[4].
-Medical Tourism: Choosing medical tourism for dental implantology can be a cost-effective option[4].
