“…The high implant success rate (97.9%) achieved in our study is in agreement with the previously published data [16,[20][21][22][23] (Table III). The study thus confirms the excellent results achieved with the protocols of immediate loading of prostheses supported by a combination of 4-6 axial and angulated implants.…”

“…This result, according to literature data [16,[21][22][23] (Table IV) validates the viability of angulated implants, even those placed in a region where bone density is usually low. Angulated implants offer an additional advantage to decrease distal prosthetic extensions while maintaining satisfactory arch length and good distribution of the mechanical stresses transmitted to the prosthetic frame and the peri-implant bone [17], all the while freeing elevations of low sinus depth, thus decreasing the time and cost of treatment.…”

“…As in the literature [20][21][22], most prosthetic complications identified in our study are represented by the resin fractures on the provisional prosthesis, which occurred in 10 patients (20.8% cases). They bear witness to the importance of good occlusal control insofar as the absence of periodontal around the implants strongly decreases proprioceptive abilities, and therefore detection of occlusal overload.…”

“…This is a percentage close to the 80% failure rate before 12 months found in our study. Similarly, Malo et al [21] shows 89% implant failures in 13 months following surgery. These figures show that the osseointegration period in the first postoperative months is the most conducive period to the implant failure.…”

--Introduction:In recent years, the immediate loading procedure for the rehabilitation of edentulous jaws has gained popularity among patients and practitioners. The purpose of this study was to evaluate implant and prosthetic success rates for the rehabilitation of edentulous maxillae using tilted distal implants and immediate loading of prostheses, after 2 years. Material and method: Patients included in the study received a complete prosthesis of the upper arch, attached to 4, 5 or 6 implants. The provisional prosthesis was fixed the same day the implants were placed. After a period of osseointegration, the provisional prosthesis was replaced by a definitive prosthesis with a titanium framework made using computer-aided design/computer-assisted manufacturing (CAD/ CAM) technology. Judgment criteria were the implant success rate, the provisional prosthesis success rate, and the definitive prosthetic success rate. Results: Two hundred and forty-two implants were placed in 48 patients. Five implants were lost, resulting in an implant survival at 2 years of 97.9%. Two provisional fixed prosthesis had to be temporarily replaced by a removable solution, resulting in a provisional prosthesis success rate of 95.8%. The definitive prosthesis success rate was 100%. Discussion: Use of a provisional prosthesis during the osseointegration period is essential, both for the preparation of the final prosthesis as well as for proper management of potential implant failures. Implant failures are more easily managed if at least five implants were originally placed.

“…Some research showed that rehabilitation in the maxillary all-on-four scheme using anterior vertical and posterior tilted implants allows survival over 95% (Maló et al, 2012a;Balshi et al, 2014). Likewise, this scheme installed in bone area with considerable bone deficiencies, post-extraction alveoli, fenestrations and "non-ideal" bone conditions generally presents a high success rate, with a bone loss of up to 1.6 mm at cervical level at 3 years of follow-up (Maló et al, 2012b).…”

The aim of this research was to evaluate the load distribution in tilted distal implants used in the all-onfour system. Two implant schemes were used. In both, two vertical anterior implants and tilted posterior implants were installed, one group with an angulation of 15º and another with an angulation of 35º. The implants were installed together with a bar binding them all in a photoelastic model obtained from a replica of an edentulous maxilla. In this model, loads were produced in the sector of the bar cantilever, the abutment of the tilted implants and over the four implants using devices specially designed for this purpose. The bands were recorded with a digital camera, and the qualitative and quantitative analyses were carried out by means of student's t-test and the Mann-Whitney test in Biostat v. 5.0, considering a level of p<0.05 to establish a statistically significant relation. In the qualitative analysis, the implant with 35º presented the greatest amount of stress on the cantilever forces at cervical level. The quantitative studies showed fewer differences in all aspects assessed, although significant differences were observed between the two systems when loads were applied at cantilever level. It can be concluded that there are minimal differences in the stress distribution when comparing implants with angulations of 15º or 35º. However, there is a greater concentration of stress at the cervical level in implants tilted to 35º.

“All‐on‐4” Immediate‐Function Concept for Completely Edentulous Maxillae: A Clinical Report on the Medium (3 Years) and Long‐Term (5 Years) Outcomes

Abstract: The high survival rates at patient and implant level indicates that the immediate-function concept for completely edentulous maxillae using the present protocol is viable in the medium- and long-term outcomes.
