“…At the same time, a long course of treatment will lead to severe discomfort of patients, and inadequate daily maintenance may cause inflammation and damage of periodontal tissue [ 16 ]. The All-on-4 immediate loading implant surgery only needs one operation, and it is easy to operate and less traumatic, which can reduce the adverse impact of the lack of teeth on the daily life of patients [ 17 , 18 ]. The All-on-4 immediate loading implant technology cleverly avoid the nerve distribution of the maxillary sinus and inferior alveolar through the preoperative detailed design and implanted the implant into the relatively dense place of the mandibular bone, so that the bone mass of the anterior mandible can be fully utilized.…”

Objective. To explore the clinical effect and aesthetics of All-on-4 immediate loading implant denture in severe periodontitis. Methods. Totally, 60 patients with dentition loss caused by severe periodontitis who were admitted to our hospital from February 2017 to February 2019 were selected. The patients were randomly divided into the observation group (n = 30) and the control group (n = 30) according to different restoration methods. The control group was used in traditional implant restoration treatment, and the observation group was used in All-on-4 immediate loading implant denture restoration. The clinical effect, periodontal index, aesthetic effect, and complications of the two groups were compared, and the levels of serum leptin (LEP), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and interleukin-6 (IL-6) were measured. Results. The total effective rate of the observation group (83.33%) was higher than that of the control group (60.00%) ( P < 0.05 ). After treatment, the plaque index, gingival sulcus bleeding index, and depth of exploration of the two groups were lower than those before treatment ( P < 0.05 ), and there was no significant difference between the two groups ( P > 0.05 ). After treatment, the serum LEP, TNF-α, CRP, and IL-6 in both groups were lower than before treatment, and the serum LEP, TNF-α, CRP, and IL-6 in the observation group were lower than that in the control group ( P < 0.05 ). The aesthetic rate of teeth in the observation group (90.00%) was higher than that in the control group (66.67%) ( P < 0.05 ). There was no significant difference in the total incidence of complications between the two groups ( P > 0.05 ). Conclusion. All-on-4 immediate loading implant denture has a good effect in the treatment of severe periodontitis, which is conducive to maintaining periodontal health, reducing the level of inflammation, improving aesthetics, and has high safety.

“…After a 3-month healing period, patients receive their permanent prosthodontic restoration (either fixed with occlusal screws or removable prostheses attached to bars). Due to a large variety of treatment approaches, very few clinical studies have examined the long-term survival rate of immediately loaded dental implants in edentulous jaws, which are later replaced by definitive prostheses, and their correlation to anamnestic risk factors [2][3][4]. Therefore, the aim of this study was to evaluate the clinical outcome of implant success within the full-arch immediate loading technique in a single-center retrospective cohort study by analyzing the 6 year survival rate of the dental implant and its correlation to oral hygiene and other risk factors.…”

Background: This study aims to show the long-time stability of straight and tilted implants loaded immediately with a provisional resin bridge followed by a definitive prosthodontic rehabilitation in edentulous jaws despite difficult hygiene conditions postoperatively. Results: This study included the participation of 23 patients and the restoration of 170 dental implants in 32 edentulous jaws. Patient data was analyzed from the start of treatment with a minimum follow-up period of 6 years in order to determine long-term implant success rates. However, the age of patients at time of surgery significantly affected the BOP to the detriment of younger patients (median 62 years old). Conclusion: Although there was a higher risk of implant failure due to general disease, all the implants in this study survived successfully. As a replacement for a complete dental arch, the reduced number of implants in combination with the avoidance of augmentations reduces treatment costs. The immediate fixed prosthetic restoration of edentulous jaws thus represents a reliable therapeutic alternative to a two-to three-stage procedure. Optimized aftercare including professional teeth cleaning (PTC) (at least twice a year) can minimize the anamnestic effect of smoking, diabetes mellitus, and osteoporosis on BOP and possible bone loss.

Background All-on-4 concept allows an immediate restoration, which is frequently a provisional restoration (PR), and will be replaced by a definitive restoration (DR) a few months later. However, this approach involves much higher treatment efforts and costs, compared to a DR immediately after implantation. PRs were mostly incorporated in the introductory phase of the All-on-4 concept in our respective clinics. Today, PRs are only used for referred patients and bimaxillary restorations. The aim of the study was to investigate whether PRs and DRs have comparable success rates. Methods A total of 126 patients with 136 All-on-4 restorations supported by 544 implants were included in this retrospective cohort study. The observation period was 1 year. In 42 cases, a PR was placed initially and replaced by a DR 3 months later. In 94 cases, a DR was placed immediately. Biological, technical, and severe (loss of an implant or PR/DR) complications associated with PRs and DRs were compared. The absence of a serious complication was considered a success. Results A total of 27 patients were affected by 33 complications, 19 biological (2 PR and 17 DR) and 14 technical (6 in PR and 8 in DR) in the first 3 months. Eight patients had ten severe complications (1 PR and 9 DR). Severe complications were all implant losses. Implant survival rate was 98.2% (99.4% PR and 97.6 DR), and restoration survival rate was 94.4% (97.6% PR and 92.6% DR). Six out of the ten implant losses occurred in the posterior maxillae of male patients. After 3 months, ten complications occurred in six patients within 1 year. One of these complications was an implant loss in the posterior maxillae of a male patient. Conclusion PRs and DRs showed comparable complication rates during the observation period. Only in male patients did implant losses occur more frequently in the posterior maxilla.
