Objective:To compare the effects of using cone beam CT (CBCT) and oral scanning registration on implant positional accuracy during robot-assisted implant surgery, and to provide a basis for selecting the appropriate registration for robot-assisted implant surgical options.Methods:One patient with dentition defect, specifically missing teeth at positions 21 and 26 and having natural teeth adjacent mesially and distally to the edentulous area, who visited the Department of Oral Implantology, School of Hospital of Stomatology Wuhan University in 2024 were selected. Based on reconstructed imaging data, 30 identical jaw models were printed. These models were divided into a CBCT registration group and an intra-oral scanning registration group (15 models per group). An associate chief physician with extensive experience in implant surgery performed preoperative registration using the implant robot and completed the implant surgeries. Postoperative CBCT scans were used to determine the three-dimensional position of the implants. The deviations between the planned implant position and the actual position were evaluated, including deviations at the implantation point, apical point, and angular deviation. The differences between the two groups were compared.Results:The implantation deviation was 0.675 (0.490) mm, apical deviation was (0.680±0.272) mm, and the angular deviation was 0.566°±0.147° in the CBCT registration group, and in the intra-oral scanning registration group, implantation deviation was 0.695 (0.313) mm, apical deviation was (0.667±0.217) mm, and the angular deviation was 0.523°±0.168°. There was no statistically significant error in implant precision between the two groups ( P>0.05). Conclusions:This in vitro experiment found that the use of intra-oral scanning registration in robot-assisted implant surgery can achieve similar implant placement accuracy as CBCT registration.

Objective To investigate the therapeutic effect of gabapentin combined with hemoperfusion on skin pruritus in the patients on maintenance hemodialysis(MHD).Methods A total of 72 patients with MHD complicating moderate to severe skin itching treated in Lianyungang Municipal Oriental Hospital from January 2023 to March 2024 were selected as the study subjects and divided into the observation group and control group by the random number table method,36 cases in each group.On the basis of symptomatic treat-ment,the control group was given hemodialysis 3 times a week and hemoperfusion twice a month;on the basis of the control group,the observation group orally took 1 gabapentin capsule every night,and the patients in the two groups continued to be treated for 12 weeks.The visual analogue scale(VAS)score,Pittsburgh Sleep Quality Index(PSQI)score,molecular toxin level and calcium and phosphorus metabolism were evaluated be-fore treatment,in 4,12 weeks after treatment respectively,and the occurrence of adverse reactions during treatment in the two groups was observed.Results After 4 weeks and 12 weeks of treatment,the VAS and PSQI scores of the observation group were decreased compared with those before treatment,moreover the scores of the observation group were lower than those of the control group in the same period,and the differ-ences were statistically significant(P<0.05);the VAS and PSQI scores after 4 weeks of treatment in the control group were decreased compared with those before treatment,but the difference was not statistically significant(P>0.05);and the VAS and PSQI scores after 12 weeks of treatment in the control group were decreased compared with before treatment,and the difference was statistically significant(P<0.05).After 4 weeks of treatment,the levels of Scr,BUN and β2-MG in the two groups were decreased compared with those before treatment,but the differences were not statistically significant(P>0.05);after 12 weeks of treatment,the levels of Scr,BUN and β2-MG in the two groups were decreased compared with those before treatment and after 4 weeks of treatment,and the differences were statistically significant(P<0.05),but there was no sta-tistically significant difference between the two groups(P>0.05).After 4 weeks of treatment,there was no statistically significant difference in the levels of blood Ca,P and iPTH between the two groups compared with before treatment(P>0.05);after 12 weeks of treatment,except for blood Ca,the levels of blood P and iPTH in the two groups were decreased compared with those before treatment and in 4 weeks of treatment(P<0.05),and the differences were statistically significant(P<0.05),but there was no statistical difference be-tween the two groups(P>0.05).There were no adverse reactions in the control group,and there were 3 cases of drowsiness,1 case of fatigue and 1 case of dizziness at the beginning of treatment in the observation group.The symptoms were mild without treatment and spontaneously relieved in about 1 week.Conclusion Gabap-entin combined with hemoperfusion could quickly and effectively alleviate the itchy symptoms of skin,improve the sleep quality,reduce the uremic toxin levels,and improve the calcium and phosphorus metabolism in MHD patients,with few adverse reactions,and the patients are easy to tolerate.

Objective:To evaluate the clinical application effects of a domestic bone-level implant system for restoring single tooth loss, and provide clinical evidence for the promotion and application of domestic implants.Methods:A prospective, multicenter clinical trial was conducted from April 2018 to January 2020 in three institutions: Department of Oral Implantology, School & Hospital of Stomatology, Wuhan University, Department of Stomatology, The First Affiliated Hospital of Zhejiang University School of Medicine, and Department of Stomatology, The Third Hospital of Hebei Medical University. The trial planned to include 100 patients for single tooth implantation and restoration, followed up for 1 year, to evaluate the implantation success rate and other related outcomes.Results:This study screened a total of 142 patients and ultimately included 100, comprising 43 males and 57 females with age of (47.0±12.2) years. Ninety-eight out of 100 patients completed a one-year follow-up (98.0%), while 2 patients terminated the trial early due to implant loosening (2.0%). After a one-year follow-up, the implants of the 98 patients were all functioning successfully, with a success rate of 98.0% (98/100). The patients were satisfied with the overall restoration effect.Conclusions:This study indicates that the domestic bone-level implant system has achieved favorable short-term clinical outcomes for single-tooth implantation and restoration.

Objective To observe and explore the effect of aripiprazole(Ari)and olanzapine(Ola)on body weight and lipid metabolism in schizophrenia(SP)patients.Methods 96 patients with SP were randomly divided into two groups,48 cases in the observation group and the control group.The control group was treated with Ola,while the observation group was treated with Ari.Before and 6 weeks after treatment,the height,body weight,blood glucose (FBG),insulin(INS),low -density lipoprotein(LDL),triglycerides(TG),total cholesterol(TC)levels in the two groups were detected,insulin resistance index(IRI)and BMI were calculated.Results The differences of body weight,BMI,FBG,INS,IRI,LDL,TG,TC before treatment between the two groups were not statistically significant (t =0.161,0.564,0.277,0.078,0.092,0.124,0.421,0.245,all P >0.05).After 6 weeks treatment,FBG,INS, IRI in the observation group were (4.71 ±0.58)mmol/L,(21.85 ±12.36)μU /mL and (4.62 ±2.14),the differ-ences were not statistically significant compared with before treatment(t =0.800,0.571,0.276,all P >0.05).Those in the control group were (5.14 ±0.56)mmol/L,(28.54 ±11.25)μU /mL and (6.23 ±3.82),which were signifi-cantly higher than those before treatment(t =4.898,3.361,2.628,all P <0.05),and were also significantly higher than those in the observation group(t =3.695,2.773,2.547,all P <0.05 ).After 6 weeks treatment,the body weight,BMI,LDL,TG,TC in the observation group were not statistically significant compared with before treatment (t =0.262,0.638,0.124,0.421,0.245,all P >0.05 ),those in the control group were significantly higher than before treatment(t =2.601,3.834,5.773,5.838,4.375,all P <0.05),and were also significantly higher than those in the observation group(t =3.052,3.265,5.264,5.496,4.188,all P <0.05).Conclusion Ari treatment for SP has no significant effect on glucose and lipid metabolism and body weight in patients,and the effect of Ola treatment on patients'body weight and lipid metabolism is more significant.
