Abstract

PURPOSE
In cases when implant supported overdenture is made by using standard size implant, additional procedure such as bone surgery and bone grafting can be required. And it gives burden to doctor and patient in terms of cost. Therefore, it is necessary to find the implant therapy for the edentulous patients in making denture with accordable cost and simple procedure.
MATERIALS AND METHODS
Edentulous patients with upper and lower dentures participated in this study. Before the operation, survey about patient's satisfaction to the existing dentures was carried out. Surgical procedures included four small diameter implants installation anterior area and immediate loading. One and three month after the procedure, the same survey about patient's satisfaction was carried out, and radiography was taken.
RESULTS
We are doing research to the nine patients. Survival rate is 97.2 percent. The comparison of patient's satisfaction before and after surgery is performed based on oral health impact profile 49. We analyze mainly with masticatory discomfort, retention, aesthetics, social problem, psychological discomfort problems. As a result, satisfaction level is increased at all factors. Retention is the most increased satisfactory factor followed by mastication difficulty, pronunciation, psychological discomfort, social discomfort, aesthetics in order. Marginal bone loss is 0.21 mm at 12 weeks after implant placement.
CONCLUSION
This research reveals that the denture supported by mini dental implant increases patient's satisfaction. This study will be continued with more patients for a long time and we are scheduled for taking additional radiography to check whether peri-implant bone resorption occurs or not.

  • Fig. 2. Drilling with pilot drill and implant placement. Implant was placed by using finger driver and thumb wrench after treated for drilling 1/3 of 1/2 length of implant by pilot drill which is 1.1 mm in diameter. Implant placement was completed by using torque wrench for tightening implant in the force of 35 N/cm.

Auto-polymerization acrylic resin was filled in the area of relief and MH-2 was attached to denture by using bite records acquired before surgery.
