Abstract
PurposeThe purpose of this study is to discuss the effect of computer-aided design or computer-aided manufacturing (CAD/CAM) guide plate combined with socket-shield technique (SST) in immediate implantation of anterior teeth aesthetic area and its influence on aesthetics.MethodsA total of 102 patients with immediate implantation in our hospital from March 2017 to March 2020 were selected. According to different repair methods, patients were divided into conventional group (n = 51) and observation group (n = 51). Traditional immediate implantation was performed in conventional group. The observation group underwent immediate implantation with CAD/CAM guides combined with SST. Immediately after operation and 12 months after operation, the success rate, implant deviation, periodontal index, absorption of labial bone plate, complications, aesthetic effects, and satisfaction of the two groups were observed.ResultsThere was no significant difference in the success rate between the two groups (p > 0.05). The implant deviation values in the observation group were all lower than those in the conventional group (p < 0.05). PD, PLI, and SBI in the observation group were all lower than those in the conventional group (p < 0.05). The absorption value of labial bone plate in the observation group were all lower than those in the conventional group (p < 0.05). The total incidence of complications in the observation group (5.88%) was lower than that in the conventional group (19.61%) (p < 0.05). The PES and WES in the observation group were higher than those in the conventional group (p < 0.05). The total satisfaction in the observation group (92.16%) was higher than that in the conventional group (76.47%) (p < 0.05).Conclusion: The application of CAD/CAM guide plate combined with SST in immediate implantation of anterior teeth aesthetic area has a good effect, which can improve the accuracy of implantation, improve the periodontal environment, reduce bone resorption, reduce complications, improve aesthetics, and have high patient's satisfaction.
Highlights
The aesthetic area of anterior teeth refers to any tooth-alveolar part that can be seen when laughing
Determining the three-dimensional position of the implant and maintaining the thickness of the labial bone wall play a vital role in the restoration of the aesthetic area of the anterior teeth, which has become an urgent problem to be solved in the current implant field
We found that the absorption value of labial bone plate and the total incidence of complications in the observation group were lower than those in the conventional group
Summary
The aesthetic area of anterior teeth refers to any tooth-alveolar part that can be seen when laughing. Immediate implantation is an oral repair technique that implants are implanted into the bone immediately after tooth extraction It has the advantages of less trauma, short period, and fewer operations and can reduce the pain of patients and the social and economic burden of patients. The aesthetic area of anterior teeth, as an important position in oral cavity, has a special anatomical structure, and patients often have higher aesthetic requirements for this area. It is undoubtedly a great challenge for most doctors to immediate implantation of aesthetic area of anterior teeth. The traditional implant operation mainly relies on the personal experience of doctors, which leads to the deviation between the implant position and the preoperative design position
