Purpose: This study intends to retrospectively analyze and compare short-term survival rate in RBM surface and acid-etched surface implants being frequently used clinically.
Patients and Methods: The subjects are 140 patients who received an RBM surface implant or acid-etched surface implant among the patients that visited hospital to rehabilitate the tooth lost between January of 2005 and March of 2007. Total implants conducted were 304, and 152 were RBM surface implants while another 152 were acid-etched surface implants. 55 patients received 152 RBM surface implants, and 85 had 154 acid-etched surface implants. The survey was conducted and recorded before and after the implants operated according to the evaluation items prepared in advance, and the patients did tracing observation for more than 12 months at least. After a year passed from the completion of all patients’ prosthetic treatment, this study compared survival rate in the implants based on their medical records and radiographs with reference to Albreksson’s criteria for successful implants and Buchs et al.’s criteria and analyzed the type and reason of failure.
Results: 152 RBM surface implants were operated to 55 patents, and one implant failed clinically and radiographically; thus, the survival rate was 99.34%. Meanwhile, 152 acid-etched surface implants were conducted to 85 parents, and seven of them failed; the survival rate was 95.39%. In regard of areas where implants failed, one failed RBM surface implant was on the posterior molar area of mandible, and the bone quality was type Ⅱ. Five failed acid-etched surface implants were conducted on the posterior area of maxilla, and two were on the posterior area of mandible. The bone quality was mainly type Ⅲ and IV.
Conclusion: According to the result above, the RBM surface implant indicated a little higher survival rate than the acid-etched surface one.
