A dental implant is one of the procedures to restore missing teeth , to achieved the stability for implant success is the direct growth of bone to the implant surface, known as Osseointegration.As a result, bone stability around dental implants is determined by factors that the implantologist may or may not directly influence, such as local bone quality and bone metabolism, as well as systemic factors such as age, systematic chronic diseases and lifestyle (e.g., smoking habits).Treatment-related factors include augmentation material, implant design (macro and micro), surgical procedures, and loading protocols. Therefore , it may be needed for a surface treatment could alter the topography, chemical content, and roughness of the surface and result in various biological reactions. The surface treatment can also increase the area of contact between the implant and the supporting bone . The rationale is evaluate Increasing the implant stability around implants placed by using hyaluronic acid that act to improving the connection between implant and bone .Sandblasting and acid etching is the most commonly used basic method for modifying the surface of dental implants . the sandblasting procedure "roughs up" the outer layer of the implant,creating a surface that is easier for the bone to grip as the implant heals.While hyaluronic acid and its derivatives have a strong chance of osseointegration and mineralization and have been utilized extensively for bone repair.

Hyaluronic acid has a huge potential to speed up the healing process and increase implant stability by enhancing bone/implant interaction and new bone formation.

It is assessed by using Osstell To determine the stability after intervention scale from 60 to 70 ISQ 60 low stability 70 high stability .

It is assessed by using gingival index in Clinical examination scale from 0 Normal 1 Mild inflammation 2 Moderate inflammation 3 Severe inflammation .
