Comparative Soft and Hard Tissue Responses to Titanium and Polymer Healing Abutments

Abstract

Limited information exists regarding soft tissue and hard tissue responses to abutments with different material composition. The aim of this study is to evaluate soft and hard tissue responses to titanium and polymer healing abutments over a 3-month period. Sixteen patients were included in this prospective trial. Implants were provisionalized with either titanium or polymer healing abutments. Changes of marginal bone level and soft tissue dimensions were recorded at implant installation and at 3 months.
