Evaluation of Crestal Bone Height Post-Implant Placement: A Comparative In-Vivo Analysis Between Calcium Phosphate Coating and Alumina Oxide Blasting: An Original Research Study

Abstract

Background: To radiographically evaluate crystal bone height changes around the calcium phosphate coated and alumino oxide blasted implants immediately, one month and three months after placement using a software in radionuclide Ventriculogram (RVG).

Methodology: This experimental randomized controlled clinical trial was conducted for a period 2 year. 30 patients with single posterior edentulous region were selected. These patients were divided into two equal groups with 15 sample size each. 15 patients were rehabilitated using alumino oxide blasted implants & 15 patients with calcium phosphate coated implants. Radiographic evaluation was done immediate after implant placement and follow up evaluation was done at one- and three-month time interval.

Results: Repeated Measure of ANOVA test &Boneferroni Post Hoc analysis were used in the study. The results of the study showed statistically significant difference in the crestal bone loss which was more in alumino oxide blasted implant as compared to calcium phosphate coated implants when measured in mm. It was 3.67±0.51 and 3.05±0.50 immediately after insertion, 3.26±0.50 & 2.77±0.56 at 1 month after placement and 3.08±0.45& 2.68±0.58 at 3-month interval after placement for alumino oxide blasted and calcium phosphate coated implants respectively.

Conclusion: Calcium phosphate coated implants were superior to alumino oxide blasted implants as measured and compared radiographically upto 3 months.
