Abstract

INTRODUCTION

Impacted maxillary canines are common problem, which orthodontists often deal with. Definition of its position is not always easy and unequivocal. The aim of this study was evaluation of incidence of uni- and bilateral impacted maxillary canines and their position in dental arch depending on gender and age.

MATERIAL AND METHODS

The records of 134 patients' documentation and panoramic views with impacted maxillary canine (IMC) were studied. Study group consisted of 96 women and 38 men in age ranging from 10 to 60 years. First group consisted of 73 patients with unilateral IMC in age ranging from 10 to 60 years. Second group consisted of 61 patients with bilateral IMC in age ranging from 10 to 25 years. Palatal-vestibular position of IMC and their syntopie was defined basing on clinical and radiological study depending on gender and age.

RESULTS

The results were presented in tables. In the first group (patients with unilateral impacted maxillary canine) 44 (60.3%) canines were localized in palatal position, 15 (20.6%) in vestibular position and 14 (19.2%) in axis position. In this group mesial syntopie was found in 33 (45.2%) patients, distal syntopie in 4 (5.5%) patients and vertical position was found in 36 (49.3%) patients. In the second group (patients with bilateral impacted maxillary canines) palatal position of impacted canines was found the most frequently. It constituted above half of patients of the second group. Vestibular position of canines was found in 11.66%, and axis position of canines in 13% of patients. Position's compatibility of canines with mesial syntopie was found in almost half of patients in this group.

CONCLUSIONS

The evaluation of position of maxillary impacted canine allows to precise clinical study and thorough analysis of panoramic view. Impacted maxillary canine is more often localized in palatal position and was more often found in women than men. Left canine was more often impacted than the right one in unilateral impacted maxillary canine group.

摘要

引言

上颌埋伏尖牙是正畸医生常需处理的常见问题。其位置的界定并非总是简单明确。本研究旨在评估单侧和双侧上颌埋伏尖牙的发生率及其在牙弓中的位置与性别和年龄的关系。

材料与方法

研究了134例上颌埋伏尖牙患者的病历记录和全景片。研究组包括96名女性和38名男性，年龄在10至60岁之间。第一组由73例年龄在10至60岁之间的单侧上颌埋伏尖牙患者组成。第二组由61例年龄在10至25岁之间的双侧上颌埋伏尖牙患者组成。根据性别和年龄，基于临床和影像学研究确定上颌埋伏尖牙的腭侧 - 前庭位置及其邻接关系。

结果

结果以表格形式呈现。在第一组（单侧上颌埋伏尖牙患者）中，44颗（60.3%）尖牙位于腭侧位置，15颗（20.6%）位于前庭位置，14颗（19.2%）位于轴位。在该组中，33例（45.2%）患者发现近中邻接关系，4例（5.5%）患者发现远中邻接关系，36例（49.（此处原文似有误，应为49.3%））患者发现垂直位置。在第二组（双侧上颌埋伏尖牙患者）中，埋伏尖牙的腭侧位置最为常见。占第二组患者的一半以上。11.66%的患者发现尖牙的前庭位置，13%的患者发现尖牙的轴位。该组近一半患者发现尖牙与近中邻接关系的位置相符。
