| Objective: By collecting and sorting out the cases of maxillary discontinuous anterior teeth loss repaired with immediate and delayed implant technology,this paper evaluates the health degree of soft and hard tissue,aesthetic effect,patients’ satisfaction,implant success rate and aesthetic complications after implant restoration at two different implant opportunities,summarizes the experience,improves the deficiencies and provides some references for related clinical implant restoration.Methods: From September 2016 to September 2017,38 patients(43 in total)who came to the implant center of Dalian stomatological hospital for implant restoration of maxillary anterior teeth were selected.The experimental group included 22 patients(25 in total)in the immediate implant group,with 7 screws retained.In the control group,there were 16 patients in the delayed implantation group,with 18 screws and 8screws retained.Record the clinical evaluation indexes on the day of the final repair,1month later,3 months later,6 months later,12 months later and 15 months later of the two groups.Such as soft tissue condition around implants(modified plaque index(m PLI),modified sulcus bleeding index(m SBI),periodontal depth(PD),pink esthetic score(PES),white esthetic score(WES),implant stability quotient(ISQ)of screw-retained implants and marginal bone loss(MBL)of the two groups which are observed by X-ray apical radiography on the same day,3 months,6 months,12 months and 15 months after implantation.Patients’ final satisfaction(VAS),retention rate,and aesthetic complications(gingival recession,gingival papilla loss,implant platform exposure,chronic gingival inflammation around the implant,shape and color of the prosthesis)during the 15-month follow-up period.SPSS23.0 was used to analyze the data of the two planting periods.P < 0.05 indicated that there were statistical differences,and the conclusion of this topic was drawn.Results: In this study,the clinical effects of immediate implantation of 25 implants and delayed implantation of 18 implants for 15 months were observed.Clinical evaluation indicators:1.There was no significant difference in the survival rate and subjective satisfaction.2.There was a statistical difference between the modified sulcus bleeding index(m SBI)and pink esthetic score(PES)(P <0.05)in the first month of follow-up,but there was no statistical difference in the later review(P>0.05).There was no significant difference(P>0.05)in the statistical results of modified sulcus bleeding index(m SBI)and periodontal depth(PD)during the review period.3.There were significant differences(P <0.05)in marginal bone loss(MBL),implant stability quotient(ISQ)in the first three months of follow-up,absorption of implant thickness in cervical and middle labial plates within one year.4.During the follow-up period,2 gingival recession and 1 gingival chronic inflammation in the immediate implant group had no obvious complications such as loss of gingival papilla,exposure of implant plateau and bad shape and color of prosthesis.In the delayed implant group,2 gingival papillae were missing in a small range,1 gingival margin receded,1 gingivae were chronic inflammation,and there was no obvious exposure of implant plateau,bad shape and color of prosthesis.Conclusion: In this paper,according to the strict and exclusion criteria,through randomized controlled statistical analysis of data collected by this research conclusion:because of the immediate planting can shorten the treatment time,the early effect of hard and soft tissue is better than the delay,the curative effect of late can obtain similar to postpone planting,so in the maxillary anterior teeth,as long as the physician in the immediate growing indications strictly controls the premise,guarantee the implant in your breath,near and far in vertical bone inside the space position of the right of the immediate planting as the preferred solution. |
