Izvi zvinodaro nekuti chishandiso chemuchina (chete chepamusoro-simba laser yekucheka michina) hachishandise kuputika uye kuchera kuita maburi madiki, asi pulse drilling (soft puncture), iyo inoita kuti laser simba riwedzere munzvimbo diki.
Nzvimbo isina kugadziriswa ichapiswawo, zvichiita kuti gomba deformation uye kukanganisa kunaka kwemaitiro.
Panguva ino, isu tinofanirwa kushandura nzira yekubaya tsinga (yakapfava puncture) kune iyo flat puncture nzira (yakajairika puncture) mukugadzirisa dambudziko rekugadzirisa dambudziko.
Kune rimwe divi, kune yakaderera simba laser yekucheka michina, pulse drilling inoshandiswa kugadzira maburi madiki kuvandudza kupera kwepamusoro.
