Healthy soft tissue response, marginal bone gain, and great esthetics in the 'one-abutment one-time' treatment
Introduction
Stable adherence of soft tissue onto the abutment and restoration surfaces is a key determinant of long-term success of implant treatment. It can be influenced by abutment surface modifications and abutment dis- and re-connection during the prosthetic phase. While gradually anodized TiUltra implant surface was developed to promote early osseointegration and support stable marginal bone, the Xeal surface at the tissue-level abutment base was designed to facilitate undisturbed mucointegration.
This study aimed to assess the clinical performance of these new implant and abutment surfaces with respect to the marginal bone levels and soft tissue response.
KEY RESULTS
-Robust papilla regeneration and marginal bone gain were reported even among the disadvantaged patient population (>50% smokers, 13% those with parafunctional tendencies, and nearly 10% with a history of periodontitis).
-Increased keratinized mucosa height was observed from prosthetic delivery to 6 months, it remained stable at 2 years with all implants surrounded by it.
-Bleeding index improved considerably from prosthetic delivery to 1 year remaining stable at 2 years, and Gingival index improved from 6 months with 98.1% of implant sites showing no inflammation at 2 years.
