The All-on-4 ® method uses four implants-two placed axially in the anterior incisor region and two placed in the posterior and angled distally up to 45 o. Tilting the posterior implants avoids interference with anatomical structures such as maxillary sinuses and inferior alveolar nerve, allows for maximum anterior/posterior spread, and. The superior and inferior limits of bone reduction are the occlusal plane and anatomical structures. The vertical dimension of occlusion can be altered within esthetic and functional parameters.. Lopes A, Ferro A, Botto J. The All-on-4 treatment concept for the rehabilitation of the completely edentulous mandible: a longitudinal study with.

Advantages of the All-on-4® treatment concept. With adequate implant design, implant surface and drill protocol, also depending on the bone quality, a sufficient primary stability can be achieved. This is a basic requirement for the immediate loading. Treatment time is reduced to one surgical intervention. The patient receives a restored. The term All-on-4, also known as All‐on‐Four and All‐in‐Four, refers to 'all' teeth being supported 'on four' dental implants, a prosthodontics procedure for total rehabilitation of the edentulous (toothless) patient, or for patients with badly broken down teeth, decayed teeth, or compromised teeth due to gum disease. It. Utilization of the "All-on-4" concept has overcome these anatomic restrictions by allowing placement of 2 vertical and 2 angled implants in the premaxilla and anterior mandible. This technique has enabled immediate placement of full arch fixed restoration at the time of implant surgery if sufficient torque is achieved.. Inferior alveolar. Presurgical cross-sectional CBCT scan slice of an All-on-4-style dental implant patient with crestal location of the inferior alveolar nerve (yellow crosshairs on nerve) secondary to bone resorption.

All-on-4 implants are a dental implant treatment created by Nobel Biocare. A type of ClearChoice implant, this surgical procedure replaces a full arch of upper or lower teeth with a new set of fixed prosthetic teeth.. These arches, or implant bridges, are attached to the upper or lower jawbone with four dental implants, tiny metal screws that replace the original tooth roots. The All-on-four concept offers various advantages. The first main benefit of this concept is that it allows a fixed rehabilitation of edentulous patients without bone grafting or advanced augmentation procedures even in severely resorbed ridges that are close to anatomical structures in both the maxilla and the mandible such as the maxillary sinus and inferior alveolar nerve, respectively []. This approach is also excellent to use without inferior border perforation if somewhat greater bone mass is available. The V-4 technique is biomechanically favorable in 3 ways: 1) mandibular continuity preservation; 2) a greater length of implants; and 3) the V-shape is very stable biomechanically. Versus the All-on-4 Concept: A Cohort Study. Implant Dent 2014;23:218-24 11 Patzelt SB, Bahat O, Reynolds MA, Strub JR. The All-on-Four Treatment Concept: A Systematic Review. Clin Implant Dent Relat Res 2013 [epub ahead of print] 12 Pomares C. A retrospective study of edentulous patients rehabilitated according to the 'all-on-four' or the

Teeth and acrylic of the all on 4 can break. This is by far the most common issue we see. Studies show that half of acrylic all on 4 prosthesis will have a tooth or acrylic fracture @ the 10 year mark. One study also shows that nearly half will have porcelain chip or break in the first 5 years as well, but I feel strongly that the type of crown. With the All-on-4™, only the 10- to 12-unit prosthesis is delivered over the four implants, and often patients request the addition of more posterior teeth to maximize chewing efficiency and improve the overall maxillofacial prosthesis. 5.. Perforation through the inferior or anterior wall of the sinus. It can be avoided by proper.
Enhanced Appearance and Confidence. All-on-4 dentures can be designed to look like natural teeth, significantly improving a patient's facial appearance and boosting self-confidence. Patients can smile, eat, and speak confidently, knowing their teeth are secure and stable. Preserved Jawbone and Oral Health. Our case report differs from the well-known current technique All-on-Four, which uses four implants in the mandible to support overdenture prosthesis ( 27 ). In addition, in All-on-Four technique, the bone availability affects the placement of the tilted implants, possibly creating cantilevers in posterior areas.

Immediate-function implants have become an accepted alternative for fixed restoration protocols in edentulous mandibles on the basis of documented high success rates. The All-on-4 concept (Nobel Biocare, Göteborg, Sweden), a surgical and prosthetic protocol for immediate function involving the use of four implants to support a fixed prosthesis in patients with completely edentulous mandibles. The All-on-4 concept described by Malo et al. [1] involves the placement of four implants in either the maxilla or mandible, with the posterior implants inclined distally up to 45°. This method eliminates advanced augmentation procedures in highly resorbed ridges by preserving the relevant anatomic structures, namely the maxillary sinus and.
