Success rates of two techniques of orthodontic microimplants placement : a prospective study

الملخص EN

maxillary and/or mandibular bone with self-drilling (sd) and pre-drilling (pd) techniques and to study whether the success rate of these techniques is affected by patients gender or not.

Methods : forty young patients equally divided into 2 groups of males and females were randomly selected among orthodontic patients at orthodontic department, Jordanian royal rehabilitation centre.

a total of 120 omis were used on a split-mouth basis.

all subjects received different microimplant insertion technique on either side of his/her maxilla and/or mandible.

being loaded immediately with an average force of 50 grams, stability of the omis was observed for a period of 12 weeks after the insertion.

fracture or loosening of the microimplant during this period was considered as failure.

the number of the succeeded and failed microimplant was then analysed statistically for the needed objectives at p<.05.

results : there were no statistical differences between the overall success rates of each insertion technique.

also, there were no statistical differences between the 2 techniques in each jaw and that no one technique showed superiority in the success rates as performed in any of the jaws.

whether performed for a male or a female, there were no significant differences in the success rates for each insertion techniques.

conclusion : neither the technique of microimplant insertion, nor the patient’s gender or the area of insertion of either maxillary or mandibular jaws showed any differences in the success rates of the microimplant at the end.
