Abstract
Some changes take place in the abutment teeth and the denture supporting mucosa due to the insertion of a removable partial denture. The blood flow volume in the oral tissue was observed by examining the difference of both the impression pressure and the retainer with the laser doppler flowmeter at the time of passing.
The results were as follows:
1. The blood flow volume on the abutment teeth attached to gingiva tend to change in the case of high impression pressure.
2. The blood flow volume in the residual ridge mucous tend to change in the case of high impression pressure.
3. The conical telescopic denture wearer's blood flow volume on the abutment teeth attached to the gingiva decreased on day 3 and returned to the insertion-day level by day 14.
4. The conical telescopic denture wearer's blood flow volume in the residual ridge mucous increased on day 3 and returned to the insertion-day level by day 28.
5. The clasp denture wearer's blood flow volume on the abutment teeth attached to the gingiva increased after insertion and returned to the insertion-day level by day 28.
6. The clasp denture wearer's blood flow volume in the residual ridge mucous increased after insertion and returned to the insertion-day level by day 28.
