Abstract
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.
Highlights
Periodontitis is a chronic inflammation of periodontal supporting tissue caused by plaque, calculus, and other factors, which has become one of the common oral diseases [1]. e early symptoms of this disease are not obvious, but with the progress of the disease, there may occur loosening and shedding of teeth, soft tissue inflammation, alveolar bone absorption, and other symptoms
Inclusion criteria were as follows: age 18–65 years; met the diagnostic criteria for severe periodontitis; missing or remaining teeth should not be retained; alveolar bone resorption of the affected tooth reaches 1/2 to 1/3 of the root length, degree II to III looseness; the patients were in good condition and could tolerate the operation; some patients were accompanied by other diseases such as cardiovascular system, digestive system, endocrine system, and other diseases, but their conditions were under control, and according to the general condition of the patients, the implant restoration had no effect on their vital signs; fasting blood glucose 3 mm, and the four-wall bone plate of the extraction socket were relatively complete
There was no difference between the two groups of periodontal indexes of plaque index (PLI), sulcus bleeding index (SBI), and probing depth (PD) (P > 0.05)
Summary
Periodontitis is a chronic inflammation of periodontal supporting tissue caused by plaque, calculus, and other factors, which has become one of the common oral diseases [1]. e early symptoms of this disease are not obvious, but with the progress of the disease, there may occur loosening and shedding of teeth, soft tissue inflammation, alveolar bone absorption, and other symptoms. Some patients have developed into severe periodontitis [2]. Patients with severe periodontitis usually have heavy alveolar bone resorption and large distance between upper and lower jaws. Most patients may develop dentition loss, which has adverse effects on chewing, pronunciation function, and appearance [4]. With the continuous development of dental implant technology, implant restoration has become an effective treatment for dentition loss. Is method is a repair method in which 4 implants are placed into the jaw bone, and restoration can be fixed on the same day. It has been widely used at home and abroad. E All-on-4 immediate loading implant technology has been carried out in our hospital for many years.
