[Abstract]:Objective: to study the application of Cerec AC immediate porcelain restoration system to the restoration of posterior tooth defect after root canal therapy, and to observe and analyze its clinical effect.Methods: in this study, 106 cases of posterior tooth defect were repaired with Sirona Cerec AC immediate porcelain restoration system.All the selected cases were treated with perfect root canal therapy by our doctor. After tooth preparation, Cerec AC chair immediate all ceramic restoration system was used for oral scanning, design, grinding and making of feldspathic ceramic pieces.After adjusting, make an immediate bonding.All the patients were followed up for 2 years. According to the modified USPHS standard, two physicians examined and evaluated the intramedullary retention inlay, and the patients filled in the satisfaction questionnaire, 69 of 106 cases were myelohyperinlay and 37 were medullary hyperinlay.All 106 prostheses were measured by the Cerec AC design software. The minimum thickness of each inlay was measured and divided into groups smaller than 1 mm ~ 1.5 mm in 1mm group and larger than that in 1.5mm group.The minimal thickness of residual teeth was measured in 69 cases of pulp hyperinlay with partial preservation of the tooth wall, and was divided into two groups: 1mm larger than 1.5 mm m ~ (-2) mm in 1.5mm group, larger than 2mm group, followed up and counted the number of failure cases in each group.SPSS 24 software was used to make statistical analysis.Results: the two-year success rate of 106 all-ceramic retention inlays was 92. 5%.The two-year success rate of all-ceramic pulp hyperinlay was 92. 8%, and that of all porcelain pulp superinlay was 91.9%.Of the 8 cases, 3 cases were lost, 4 cases were broken, and 1 case was broken of abutment teeth.The thickness of restoration was less than that of 1mm group in 3 cases, 1mm-1.5mm group in 1 case, the thickness of restoration was greater than that in 1.5mm group, and in abutment tooth fracture group, the thickness of residual tooth wall was greater than that of 1mm group, and 1 case in group 1. 5 mm ~ 2 mm in 1mm group, and 1 case in group 1 in 1mm-1.5mm group, and 1 case in group 1 in which the thickness of residual tooth wall was greater than that in 1mm group.No tooth fracture occurred in 2mm group.According to the modified USPHS criteria, 105 prostheses were evaluated after 2 years follow-up in this study.The margin fitness of medullary hyperinlay was up to 97B standard, the integrity of restoration reached A standard and the ratio of restoration integrity to A standard was 3. The proportion of gingival health to A standard was 96, and that to B standard was 4 percent. Edge staining was to A standard.The percentage of 97 percent is 97, and that of the B standard is three.92B standard for marginal fitness of medullary hyperinlay, 8 for restoration integrity and 92b standard for A, 92 for gingival health and 8 for B standard, and 8 for edge staining and A standard for gingival health, and 8 for A standard for gingival health and 8 for A standard for marginal staining.The proportion of B's is 97, and the proportion of B's is three.The survey of patients' satisfaction with the restoration showed that 94% of the patients were satisfied with the prosthesis in general, and 73% of the patients were very satisfied with the prosthesis, in terms of shape, color, comfort and cost of the restoration,Patients had the highest satisfaction with comfort, with 90% feeling very satisfied.Conclusion the pulp cavity retention inlay designed by Cerec AC system is effective and satisfactory in the treatment of posterior tooth defect.The decent thickness of feldspar ceramic restoration should be more than 1.5 mm, and the thickness of residual tooth wall of abutment had no effect on the success rate.
