Purpose: Recently, dental implant systems have been widely used for the treatment of the extraction site, but we have been confronted with many limitations in esthetics, phonetics and function. Transitional implants(TI) were developed as a method of providing fixed provisional restorations during conventional implant healing. Until now, little data have been provided on korean transitional implants. The purpose of this study is to evaluate the implant placement site histologically after 4 weeks and 8 weeks.
Materials and Methods : Test group( IntermetzzoTM MEGAGEN, KOREA) and control group(Mini Drive Lock, Intra Rock, U.S.A.) were immediately placed in interseptal or interproximal bone of beagle dog after mandibular premolars extraction, and had a healing period with non-submerged state but without loading, Both TI surfaces were composed of rough surfaces.
Results: In the test group, the average percentage of BIC were respectively 39.40%(SD7.35) after 4 weeks and 44.05%(16.76) after 8 weeks, and In the control group were 50.75%(1.48) and 59.40%(0.00). Discussion: We evaluated the initial ability of the osseointegration of TI through this study. Because TI is placed with a conventional implant simultaneously and loaded immediately, the ability of osseointegration is a very important factor for the success of TI during the initial healing phase.
Conclusion: The results of the histological evaluation of these two groups were similar to those mentioned in other studies for osseointegration of implant.
