Abstract
Objective : This research compared stabilities between two types of dental implant (SLATM, Institut Straumann AG, Waldenburg, Switzerland and SSⅡTM, Osstem co, Busan, Korea) using Osstell Mentor (Integration Diagnostics AB, Goteborg, Sweden) considering surgery methods, surgery area, diameter of implant, systemic disease, and smoking for obtaining prognosis information when installing fixture of dental implant.
Materials & Methods : 206 implants of 131 patients taken by resonance frequency analysis (RFA) were determined as a final sample. Dental implants were installed as protocol of supplier by a excellent dentist who had 10 years experience about dental implants. Before connecting abutments (3 months after installation of fixture), RFA were measured twice for buccal and lingual direction to obtain average value.
Results : Dental implants at mandible showed significantly higher stabilities significantly than at maxilla (p<0.001). Diameter 4.8 implants had also higher stabilities than diameter 4.1 in case of SLATM implants (p<0.001). SLATM implants showed more excellent stabilities than SSⅡTM implants, especially at posterior area of mandible (p=0.045) and premolar area of maxilla (p=0.032).
Conclusions : This research revealed higher stabilities of SLATM implants than SSⅡTM implant, especially at posterior area of mandible (p=0.045) and premolar area of maxilla (p=0.032).
