Abstract

Aim: This study aimed to evaluate the effect of hydroxyethyl cellulose adhesive strip in soft tissue
preservation over immediately-placed dental implants in the mandibular molar area. Materials and Methods: Sixteen patients with non-restorable mandibular molars were equally randomized into two groups (n = 8). Following atraumatic extraction and immediate implant placement, group I received only figure-eight sutures, while group II received hydroxyethyl cellulose (HEC) adhesive strips covering the socket before suturing. Clinical evaluations included Landry soft tissue healing index and implant stability. Radiographic evaluation using CBCT was used to assess relative bone density and marginal bone loss. Results: All implants exhibited a 100% survival rate with no complications during the observation period. Both groups showed significant improvement in soft tissue healing over time (p < 0.001) with no intergroup differences. Implant stability, bone density, and marginal bone loss revealed comparable outcomes between groups (p >0.05). Conclusion: HEC adhesive strips demonstrated no significant superiority over conventional suturing in preserving soft tissue health or increasing bone density around immediately-placed implants in mandibular molar area.
