The influence of tissue biotype in natural dentition is already well demonstrated in the literature, with numerous articles showing that thicker tissue is a preferred biotype for optimal surgical and prosthetic outcomes. In this same line of thought, current studies are directed to explore whether mucosal thickness would have similar implications around dental implants. The purpose of this review was to investigate the effects of soft tissue biotype in relation to success of implant therapy. The influence of tissue biotype was divided into 3 main categories: its relationship with periimplant mucosa and the underlying bone, immediate implant placement, and restorative outcomes. Soft tissue biotype is an important parameter to consider in achieving esthetic implant restoration, improving immediate implant success, and preventing future mucosal recession.
