Abstract
The purpose of this article is to confirm the longterm biocompatibility of national Avana implant and international ITI implant in dogs. At the fourth month after extraction of the mandibular third and fourth premolar in three dog, both implants were inserted using careful atraumatic technique and prosthetic abutments were applied onto the implants in three months. After that, the implants were examined by naked eye and radiographic image every three months during 1 year, for detection of the complications, such as, mobility, bone resorption and wound infection.
At 1 year after application of prosthetic abutment, the dogs were sacrificed for the histopathologic analysis by light microscope. The results obtained were as follows;
1. All implants had the ralatively good prognosis without mobility, wound infection and moderate bone resorption, in clinical and radiological evaluation during one year.
2. The all histopathologic specimens at one year after application of prosthetic abutment onto the implants showed the distinct osseointegration between implant system and bone, with projection of new bone apposition onto the peri-implant tissue. But Avana implants had the less osseointegration than ITI implants in the cancellous and marrow layer of jaw bone.
3. The all histopathologic specimens at one year after application of prosthetic device showed the firm junction by dense connective tissue pattern between the implant and the gingival portion. But Avana implants had the less firmer junction than ITI implants.
4. The authors confirmed that Avana implant and ITI implant have more higher tissue biocompatibility in dental implantation, but ITI implant has the more osseointegration than the Avana implant.
