| Popis: | To prospectively evaluate the success and survival rates of band and loop (BL) compared to crown and loop (CL) space maintainers.Thirty-six children were divided into two groups (18 BLs and 18 CLs) matched for gender, age and the extracted tooth. For the study group, all clinical procedures were performed by the same paediatric dentist. Regular follow-up appointments were scheduled at 4-6 months. Comparisons in survival time and variables which might have affected the mean survival time were tested using Log rank and Chi-square tests.A total of 16 girls and 20 boys (3.4-6.3 years old) were included. The overall failure rate was 53 %. For BLs, the failure rate was 83 % compared to 22 % for CLs. The main reason for failure of BLs was decementation (87 %), while for CLs, it was solder breakage (75 %). The mean survival time for BLs was 18.8 months, and for CL, it was 40.4 months (p0.001).The failure rate and mean survival time for CLs were clinically and statistically significantly better than those for BLs. Depending on the clinical presentation of the abutment tooth and the intended life expectancy of the space maintainer among other factors, it is recommended that, where a space maintainer is indicated in the primary dentition, preference is given to CL over BL space maintainers. |
