Objective: To compare the imaging differences of immediate implant healing between type 2 diabetes mellitus and control group. Methods: Ten patients with diabetes mellitus and ten patients without diabetes mellitus were selected as controls. Under the condition of controlling blood sugar in normal range during perioperative period, single tooth was implanted immediately. CBCT was used to observe the difference of bone mineral density (BMD) in the neck, middle and apex of implant and the width of transmission area around implant in diabetic group and control group immediately and three months after operation. Results: There was no significant difference in bone mineral density between diabetes mellitus group and control group(F=1.37, P=0.24>0.05). The results of variance analysis of transmissive zone width around implants showed that there was statistical significance(F=21.86, P<0.01). The mean width of the transmission zone in the neck of the diabetic group(1.27+1.34mm) was higher than that of the non-diabetic control group(0.51+0.47mm). Conclusion: The bone mineral density around immediate implants in type 2 diabetes mellitus patients was similar to that in control group when blood sugar was controlled in normal range during perioperative period. However, the formation of new bone in neck of implants in type 2 diabetes mellitus patients was slow, and the long-term effect needed to be further observed.

Objective: To explore choices of implants and restoration for patients with single tooth loss and root level horizontal bone deficiency due to different reasons. Methods: Employ one-stage conical implant or combined small-diameter implants which match root level horizontal bone deficiency, and adopt flapless microinvasive implantation techniques to perform operations. Then polish abutment and finish immediate restoration for one-stage conical implant, or perform temporary restoration to anterior teeth using aesthetic denture(no restoration to posterior teeth) and permanent restoration 3~5 months after the combined small-diameter planting operation. Results: The immediate restoration using one-stage conical implant brings aesthetics, comfort and confidence to patients. From the aesthetic aspect, the permanent restoration gets the appearance, color and texture of crown closer to natural teeth and make patients more satisfied. Conclusion: Choose conical or small-diameter implants to match patients who suffer root level horizontal bone deficiency due to missing teeth or alveolar bone deficiency, and perform microinvasive operation and aesthetics restoration. This method can simplify the operation process, relieve much of the pain and achieve the aesthetic restoration effect, such that it is greatly recommendable.

Objective: To study the clinical effect of immediate and delayed implantation on patients with periodontal disease after tooth extraction. Methods: Six databases including PubMed, Cochrane Library, and CNKI were searched up to December 2019. The two authors independently performed literature screening, data extraction, and bias risk assessment. Data were extracted and statistically analyzed using RevMan5.2 software. Results: A total of 8 studies were included. The meta-analysis showed that the red aesthetic score at 3, 6 and 12 months after implantation was higher in the immediate implant group than the delayed implant group. The amount of bone resorption in the neck of the immediate implantation group was lower than that of the delayed implantation group, and the difference was statistically significant; there was no statistical difference in the depth of exploration and the success rate of implantation between the two groups. Conclusion: The similar long-term treatment effect can be obtained with immediate and delayed implanting. Immediate implanting in the short term has better results than delayed implanting. Randomized controlled experiments requiring larger samples and longer observation times for more reliable results.

Objective: To analyze and evaluate the effects of two different extraction site preservation methods on the aesthetic effect of alveolar bone and alveolar bone resorption in the sockets with three-wall bone defects. Methods: 18 cases of minimally invasive extraction were selected. They were divided into 2 groups: GBR site preservation with flap (group A), site preservation with flapless (group B). Observe the soft tissue healing after surgery, the aesthetic effect of alveolar surgery at 5 months after surgery and alveolar bone resorption. Results: (1)The soft tissue in group A healed well after surgery, but the soft tissue in group B was not completely closed in the early stage. (2)The alveolar aesthetic effect of group A was better than that of group B(p<; 0.05). (3)The increased height of alveolar bone in group A was 7.33±; 0.21mm, in group B was 4.02±; 0.31mm. There were significant differences between the two groups(p<; 0.05). The reduced width of alveolar bone in group A was 0.47±; 0.14mm, in group B was 2.25±; 0.62mm. There were significant differences between the two groups(p<; 0.05). Conclusion: When the extraction sockets were three-wall bone defects in the anterior area and maxillary premolars area, the clinical effect of GBR site preservation with flaps was better than site preservation with flapless.

Objective: To analyze the application value of minimally invasive non-flap technique in oral implantation. Methods: In this study, 100 cases of oral implantation-treated patients in our hospital from January 2019 to January 2020 were taken as the research objects, and divided into two groups by random number method, with 50 cases in each group. The control group received traditional valvular technique treatment, while the experimental group received minimally invasive valvular technique treatment, and the clinical efficacy was compared. Results: Implantation time(0.45±0.46) h, postoperative hormone use time (29.13±8.06) h, postoperative antibiotic use time (35.05±7.25) h, postoperative swelling duration(4.10±1.3) h, and postoperative pain duration(29.48±5.82) h in the experimental group were all lower than those in the control group (P<0.05). The alveolar bone absorption (0.13±0.01) mm in the experimental group was lower than that in the control group, while PES score(14.32±1.19) and WES score (9.42±1.20) were higher in the experimental group(P<0.05). There was no significant difference between the planting success rate of 96.00% in the experimental group and 94.00% in the control group(P> 0.05). There was no significant difference in the incidence of adverse reactions between the experimental group(4.00%) and the control group(8.00%)(P>0.05). Conclusion: Minimally invasive non-flap technique has a significant effect on oral implant patients, which can shorten the implantation time, improve the aesthetics, and reduce the amount of alveolar ridge bone absorption. It is worthy of popularization and application.
