To report the frequency of common complications and their levels in metal-ceramic fixed dental prostheses (MC-FDPs).
A Descriptive Cross-sectional study was conducted at the Prosthodontics Department, Khyber College of Dentistry Peshawar from January 2011 to October 2012. Using a structured proforma, data from 139 subjects fulfilling the inclusion and exclusion criteria for the study and reporting complications in their MC- FDPs were collected using the method of interview, clinical & radiographic examination.
Of 139 subjects (Mean age = 34+ 6.4 Years), 81 (58.3%) were males and 58 (41.7%) were females with a male to female ratio of 1.4:1. De-cementation was the most common complication (41.7%). Least common complication was secondary caries (6.5%). Level-1 complications were more prevalent (77.7%) than level-2 complications (22.3%). In 91.4% cases, complications occurred before the FDP completed their fifth-years' service life with 25.2% of these occurring within the first years' service life.
Irrespective of the type of complications, level-1 complications were more common with de-cementation being the most common complication. One-quarter of all the complications occurred within the first-year service life of the FDPs highlighting concern over the quality of the provided MC-FDPs. .
报告金属烤瓷固定义齿(MC-FDP)常见并发症及其程度的发生频率。
本研究为描述性的横断研究,于 2011 年 1 月至 2012 年 10 月在白沙瓦牙科医学院修复科进行。使用结构化的表格,通过访谈、临床和影像学检查,收集了符合研究纳入和排除标准并报告 MC-FDP 并发症的 139 名受试者的数据。
在 139 名受试者中(平均年龄为 34+6.4 岁),81 名(58.3%)为男性,58 名(41.7%)为女性,男女比例为 1.4:1。离位是最常见的并发症(41.7%)。最不常见的并发症是继发龋(6.5%)。一级并发症比二级并发症更常见(77.7%比 22.3%)。在 91.4%的病例中,并发症发生在 FDP 完成其五年使用寿命之前,其中 25.2%发生在第一个使用寿命年内。
无论并发症类型如何,一级并发症更为常见,其中离位是最常见的并发症。四分之一的所有并发症发生在 FDP 的第一年服务寿命内,这突显了对提供的 MC-FDP 质量的关注。
