CLINICAL AND RADIOGRAPHIC EVALUATION OF THE EFFECT OF HYALURONICACID SURFACE TREATMENT VERSUS SANDBLASTED ACID ETCHED SURFACE TREATMENT ON STABILITY OF DELAYED DENTAL IMPLANT IN POSTERIOR MAXILLA (COMPARATIVE RANDOMIZED CLINICAL TRIAL)

Abstract

This randomized clinical trial evaluated the stability of delayed dental implants in the posterior maxilla, comparing hyaluronic acid surface treatment to sandblasted acid-etched surface treatment. Twenty patients, aged 18-60, were divided into two groups: Group A (hyaluronic acid) and Group B (acid-etched sandblast). Implant stability was measured at baseline and three months postoperatively using AnyCheck devise implant stability. Additionally, soft tissue healing and bone density were assessed through clinical examination and CBCT scans, respectively. Results indicated no significant difference in AnyCheck scores between the two groups at baseline and three months. However, within-group analysis showed a significant increase in AnyCheck scores for the acid-etched sandblast group after three months, while the hyaluronic acid group did not exhibit significant changes. Bone density measurements revealed no significant differences between the groups at any time point, though the acid-etched sandblast group showed significant improvement over time. Implant success rates were 70% for the hyaluronic acid group and 100% for the acid-etched sandblast group, with no statistically significant difference between the groups. In conclusion, while both treatments are effective, sandblasted acid-etched implants demonstrated superior stability and bone density improvement over time compared to hyaluronic acid-treated implants.
