| Abstract: | Objective To study domestic metal preformed crowns for restoration of large dentin defect of primary molars and to evaluate the clinical effect.Methods One hundred and nine normal clinical crown models of primary dentition were measured and related data were collected depending on anatomical characteristics of primary molars. Metal preformed crowns with nickel chromium alloy were made by punching method to restore fifty-nine teeth of fifty-five children. Clinical follow-up were performed at 2, 4, 12, 24, 48,72,96 weeks after restoration.Results There were 41 teeth in excellent, 15 teeth in good and 3 teeth in failure according to evaluation criteria. The clinical success rate was 94.92%.Conclusion Domestic metal preformed crowns can be used for restoration of dentin defect of primary molars. |
