0.05). 2. At the total success rate, osteotome group was 92.4% and Hatch reamer group was 94.9%. There was no statistically significant difference between the two groups (P > 0.05). 3. On the discomfort during the operation by using numerical rating scale, osteotome group was 2.87 +/- 0.83 and Hatch reamer group was 1.12 +/- 0.64. There was statistically significant difference between the two groups (P < 0.05). The Hatch reamer group' clinical results was similar to osteotome group and we thought that Hatch reamer technique can overcome the faults of osteotome technique.
