Clinical Case Reports Of Implant Restoration In Aesthetic Zone

Objective:The loss of teeth in the aesthetic area for any reason will pose a great threat to the beauty of the face,seriously affecting people’s social and psychological.The alveolar bone absorption and soft tissue defects caused by the loss of teeth in the aesthetic area also pose challenges for late planting and repair.Efficient,simple,and aesthetic planting restoration is gradually being paid attention to patients and doctors.The purpose of this paper is to explore the clinica operation of dental implant to repair the missing teeth in oral aesthetic area.Materials and Methods:Totally 6 patients who received the treatment of implant in the aesthetic area in Stomatological Hospital affiliated to Zhejiang University from October 2016 to October 2018 were enrolled in this study,including 2 males and 4 females,aged between 20-30 years old,with implants 8 implanted.The pieces are located in the oral aesthetic area.One of the implants is planted immediately,the four implants are planted early,and the three implants are postponed.The oral cavity was first examined before surgery,and then the panoramic film and CBCT were taken in the hospital to measure the available bone in the implanted area,and to evaluate the bone density of the operation area,and use CBCT’s own measurement software or Third-party assistive software NNT quantitative analysis of CBCT data can be used to develop a detailed planting plan using the bone mass of the alveolar bone and pinpointing the position of the implant to determine the optimal implant placement in the procedure.The patient completed the imaging examination and the routine oral examination before the operation,and explained the implantation plan and the costs involved,the treatment cycle and other issues to the patient in detail,and signed the informed consent form of the implanted surgery after the patient knew it.Before the inplantation,minimally invasive extraction,site preservation,gingival induction and other techniques to preserve soft and hard tissue,select immediate or early,delayed implantation,combined with bone growth techniques such as GBR.In this group of cases,8 implants were implanted in the aesthetic area,6 Nobel bone implants were implanted in the maxillary aesthetic area,and 2 Nobel bone implants were implanted in the mandibular aesthetic area.Immediately or early postoperatively,fixed dentures were temporarily implanted,and temporary dentures were used for gingival induction.patients review on a regular basis.In order to ensure the aesthetic effect,the shape of the tenporary restoration was continuously adjusted.After the shape and height of the nipple are stabilized,the application of personalized porcelain base platforms,ASC angle screw channel base platforms and other repairing technologies to complete permanent denture prosthetics.Results:After 6-12 months of clinical efficacy observation,none of the 6 patients had any shedding,no loosening,and the retention rate reached 100%.All 6 patients completed permanent denture prosthetics.In the 6-12 months of review,the results of the repair evaluation were evaluated using the Pink Esthetic Score(PES)and White Esthetic Score(WES)scoring system standards proposed by Belser et al.The lowest PES in this group,the value is 8 points,the highest is 9 points,the average is 8.5 points.The lowest value of WES is 8 points,the highest is 9 points,and the average is 8.67 points.After 6 months to 1 year,the roots of PES and the soft tissue color and color are found.The score of the texture is the lowest,and the score of the edge of curvature is the highest;the scores of transparency/personalization are the lowest among the five variables of WES,and there is no significant difference between the other variables.Overall,its white aesthetics and red aesthetics are better.The ideal clinical aesthetic repair effect,soft tissue aesthetics has also been significantly improved,and the patients are satisfied with that.Due to strict preoperative indications,the correct surgical technique was used during the operation and the correct repair method was adopted after sxurgery to ensure stable integration of the implant and alveolar bone,and the soft tissue morphology was harmonious and beautiful,although the sample of this group of cases,the amount is not large,the tracking time is not long,but they have also achieved satisfactory aesthetic restoration effects.Conclusion:Whether it is immediate planting,early planting or postponed planting,by strictly grasping the surgical indications,intraoperative minimally invasive operation to protect soft and hard tissues,and in addition to insufficient bone mass,GBR and other bone increment techniques are used to ensure softness around the implant.The quality of the hard tissue,and the application of gingival induction molding,personalized base table,and ASC base table are applied after implantation can effectively preserve the morphology of the alveolar bone and soft tissue around the implant in the aesthetic area,and obtain the ideal aesthetic effect and patient satisfaction in the aesthetic area.After the restoration was completed,PES and WES scoring system standards were used to evaluate the restoration effects,and the red aesthetics and white aesthetics of the cases were objectively and comprehensively evaluated to facilitate the guidance of later clinical practice.The follow-up time of this group of cases is short,there are many shortcomings,some cases still have aesthetic defects,still need to be followed up.
