편측성 Pterygoid Extension Subperiosteal Implant의 1 日 (4 시간) 장착의 새로운 시도 증례

A CASE OF EXTENSION ONE STAGE THE MAXILLARY UNILATERAL PTERYGOID SUBPERIOSTEAL IMPLANT PERFORMED WITH OPERATION

The authors have performed the maxillary pterygoid extension subperiosteal implant on the upper right partial edentulous free end case in a 52 year old woman by using one stage opera tion instead of two stage. The placement of the implant frame could be finished within 4 hours after taking the impression surgically. We suggest that one stage operation has advantages to prevent the reexposure of alveolar bone which will be happened in two stage operation, and so, to be able to reduce the resorption of alveolar bone and to decrease the patient’s emotional strains . Now, after one year, she is satisfied functionally, esthetically and mentally.
