Abstract
We clincally studied the method of the application of hydroxyapatite granules (HAP) for improving the maxillary alveolar ridge with flabby tissue.We already reported the way of thinking, procedures and results concerning HAP application in three patients.
For the initial fixation of the ridge with HAP, we anchored the splint to the zygomatic process, but this method had some problems.
The purpose of the present study was to evaluate a new method for improving the initial fixation to lessen the patient's pain.
This time we tried to fix the ridge with HAP by using Druckfender' in a patient, which presses the upper and lower dentures against the respective ridges.
The effect of this method on the initial fixation of the operated area was evaluated radiographically, morphologically, phisiologically, etc.
The new method had the following advantages in comparison with the old method.
1. The operation without general anesthesia.
2. The fixation without infection caused by surgical treatment.
3. The treatment with less pain.
4. Easier observation and treatment at the time of follow-up examination.
For the results of observation and comparison, it was suggested that the method for connecting the splint with the lower denture by using Druckfender' could be useful for the initial fixation of the operating area in edentulous patients.
