임프란트 표면 처리에 따른 초기 골유착 평가 = In Vivo Evaluation of Osseointegration on the Modified Dental Implants Surfaces

다국어 초록 (Multilingual Abstract)

The surface treatment to improve osseointegration and bio-compatibility is the core technique in dental implant. Various coating techniques has been developed and sandblasting and acid etching are most frequently used currently. These two techniques are advantages in inducing fast adhesion of cells by making the rough titanium surface to increase surface area thereby, to facilitate the early fixation of implant by mechanical occlusion. However, the remains of alumina particles and acid; the main materials used for surface treatment can lead to the implant failure.
This experiment has been performed to evaluate the osseointegration of implants with anodizing and anodizing and nano Ca-P coated surface, which are recent and most popular surface treatment techniques (fourth generation) in the world. For comparison with the control group, anodizing and anodizing and nano Ca-P coated implants were made thin and short.
Sixty implants treated by previous surface-treatment techniques, 15 anodinizied implants, and 15 nano Ca-P coated implants were implanted in 15 dog''s mandiblar premolar area. Animals were sacrified at 1, 2, 4, 8,and 12weeks after implantation and observed.
Anodizing and nano Ca-P coated surface showed higher BIC(Bone to Implant Contact, p= 0.001) and BA(Bone Area, p =0.0006).
Our results suggest that anodizing and nano Ca-P coated surfaces seem to be an excellent surface treatment method and useful clinically.
