Evaluation on the efficacy and safety of calcium metaphosphate coated fixture.

Cho IH, Lee JH, Song YG, Kim YM, Jeon SY - J Adv Prosthodont (2013)

Bottom Line: This study targeted 50 implants from 44 patients who visited Dankook University Dental Hospital.Calcium metaphosphate has a quicker biodegradation process through hydrolysis compared to other phosphate calcium groups.For the first year of the implantation, the resorption volume of marginal bone analyzed via radiography and perio-test value were measured, under the check plan.

ABSTRACT

Purpose: The purpose of this study was to assess the difference in efficacy between calcium metaphosphate (CMP)-coated implant fixtures and conventional resorbable blasted media (RBM) processed implant fixtures.

Materials and methods: This study targeted 50 implants from 44 patients who visited Dankook University Dental Hospital. Implantations were done separately for RBM treated and CMP-coated implants, although their design was the same. Calcium metaphosphate has a quicker biodegradation process through hydrolysis compared to other phosphate calcium groups. For the first year of the implantation, the resorption volume of marginal bone analyzed via radiography and perio-test value were measured, under the check plan. Their analyses were composed of a non-inferiority trials test. A 95% level of reliability was used.

Results: In the comparative analysis of the resorption volume of marginal bone and the perio-test value, no statistically significant difference was found between the CMP-coated implants and RBM implants.

Conclusion: One year after the implant placement, CMP-coated implants were found not to be inferior to the conventional RBM implants.

Figure 1: Measurement of periotest value with periotest.

Mentions: One year after the placement of fixtures, Periotest (Siemens AG, Bensheim, Germany) was used. The Periotest value (PTV) was measured at the prosthetic level (Fig. 1). To reduce the measurement error, measurement was repeated 3 times until the same value was measured. For the radiographic scan, Kodak insight film (Kodak Co, California, USA) placed perpendicularly from the implant fixtures was used (Fig. 2). Afterward, using an Epson expression 1600 pro scanner (Seiko Epson Co., Nagano, Japan), scanning was done at 1,200 dpi resolution. A 1,024 × 765-pixel Syncmaster 155MP monitor (Samsung Electronics, Suwon, Korea) was used for all measurements by one person. The measurements for bone absorption were based on the first screw helix of implant fixtures and were revised with the pitch of the fixtures as referenced.
