Abstract

STATEMENT OF PROBLEM

Zirconia has established its role as a reliable ceramic material for fixed prostheses.

PURPOSE

The purpose of this retrospective study was to evaluate the outcome of zirconia single crowns made by predoctoral students after 2 to 6 years of clinical service.

MATERIAL AND METHODS

A cohort of 88 patients treated with zirconia single crowns (mean 3 crowns per patient, range 1 to 12 crowns) from 2007 to 2010 by predoctoral dental students was identified. The patients were invited to attend a clinical examination.

RESULTS

Sixty-six participants (75%) took part in the clinical follow-up (30 women and 36 men; mean age 60.4 years, range 19 to 81 years). Altogether, 190 teeth with single crowns were examined, and the mean follow-up time was 3.88 years (1.85 to 6.04 years). The most common complications were chipping of veneering porcelain (4%) and loss of cementation (4%). The success rate of the zirconia single crowns after 2 to 6 years was 80% and the survival rate 89%.

CONCLUSIONS

Zirconia crowns can be successfully used in predoctoral dental education. The success rate of zirconia single crowns after 2 to 6 years was 80% and the survival rate was 89%, in accordance with previous studies.

摘要

问题陈述

氧化锆已确立其作为固定修复体可靠陶瓷材料的地位。

目的

本回顾性研究的目的是评估博士前学生制作的氧化锆单冠在临床使用2至6年后的效果。

材料与方法

确定了一组在2007年至2010年期间由博士前牙科学生用氧化锆单冠治疗的88例患者(平均每位患者3颗冠,范围为1至12颗冠)。邀请这些患者参加临床检查。

结果

66名参与者(75%)参加了临床随访(30名女性和36名男性;平均年龄60.4岁,范围为19至81岁)。总共检查了190颗有单冠的牙齿,平均随访时间为3.88年(1.85至6.04年)。最常见的并发症是饰面瓷崩裂(4%)和粘结剂脱落(4%)。氧化锆单冠在2至6年后的成功率为80%,生存率为89%。

结论

氧化锆冠可成功用于博士前牙科教育。氧化锆单冠在2至6年后的成功率为80%,生存率为89%,与先前的研究一致。
