The aim of this study was to investigate the effect of immediately loaded mini dental implants (MDIs) used to support mandibular overdentures on the peri-implant bone level as well as patients' related levels of satisfaction and quality of life.
Four MDIs were placed in the interforaminal region of 10 completely edentulous patients, and the implants were loaded immediately (same day) with an overdenture. Radiographic assessment of the bone loss during a period of 18 months was performed by measuring the bone level changes at the mesial and distal aspects of each implant on panoramic radiographs. At the end of this period, patients' satisfaction level on the visual analog scale (VAS) and oral health-related quality of life was assessed by means of questionnaires.
A mean bone loss of 1.04 mm on the mesial and distal sides was recorded during the 18-month period after loading of the implants. The score for general satisfaction level was 95.67 ± 5.68. Similarly high VAS scores were given by the patients in all other specific items on patient satisfaction. The total score for the Oral Health Impact Profile-20 (OHIP-20) was 34.07 ± 13.90, which was comparable to that recorded in other studies.
The short-term radiographic peri-implant bone level changes of MDIs immediately loaded with overdentures in the edentulous mandible were within the physiologic limits. The patients expressed a high level of satisfaction and oral health-related quality of life with this treatment modality.
本研究旨在调查即刻负载的微型牙种植体（MDIs）用于支持下颌覆盖义齿对种植体周围骨水平以及患者相关的满意度和生活质量的影响。
在10例全口无牙患者的孔间区域植入4枚MDIs，并即刻（同一天）用覆盖义齿进行负载。通过在全景X线片上测量每个种植体近中和远中面的骨水平变化，对18个月期间的骨丢失进行影像学评估。在这一阶段结束时，通过问卷调查评估患者在视觉模拟量表（VAS）上的满意度以及与口腔健康相关的生活质量。
种植体负载后的18个月期间，近中和远中侧的平均骨丢失为1.04 mm。总体满意度评分为95.67±5.68。患者在患者满意度的所有其他具体项目上也给出了同样高的VAS评分。口腔健康影响量表-20（OHIP-20）的总分是34.07±13.90，与其他研究记录的结果相当。
在下颌无牙颌中即刻用覆盖义齿负载的MDIs的短期种植体周围骨水平影像学变化在生理限度内。患者对这种治疗方式表达了高度的满意度以及与口腔健康相关的生活质量。
