Abstract

OBJECTIVE

The aim of this study was to compare the efficiency of two protocols for maxillary molar intrusion with two or three mini-implants.

METHODS

Twenty five maxillary first molars extruded for loss of their antagonists in adult subjects were selected. The sample was divided into two groups, according to the intrusion protocol with two or three mini-implants. Group 1 consisted of 15 molars that were intruded by two mini-implants. Group 2 consisted of 10 molars intruded by three mini-implants. Changes with treatment were analyzed in lateral cephalograms at the beginning and at the end of intrusion of maxillary molars.

RESULTS

Results showed that there was no difference in efficiency for the two intrusion protocols. It was concluded that extruded maxillary molars can be intruded with two or three mini-implants with similar efficiency.

摘要

目的

本研究的目的是比较使用两颗或三颗微型种植体的两种上颌磨牙压低方案的效率。

方法

选择25颗因成人对颌牙缺失而伸长的上颌第一磨牙。根据使用两颗或三颗微型种植体的压低方案将样本分为两组。第1组由15颗通过两颗微型种植体压低的磨牙组成。第2组由10颗通过三颗微型种植体压低的磨牙组成。在上颌磨牙压低开始时和结束时，通过头颅侧位片分析治疗中的变化。

结果

结果表明，两种压低方案的效率没有差异。得出的结论是，伸长的上颌磨牙可以通过两颗或三颗微型种植体进行压低，效率相似。
