The Effect of Immediate Implant Placement and Immediate Loading on Interdental Papillae Heights in Single Implants and Adjacent Implants

This study purposed to evaluate papilla height changes after immediate implant placement and loading in single implants and adjacent implants. A total of 33 implants were placed immediately to the extraction sockets and all the implants were immediately loaded. While 16 of implants were single (SI), 17 of implants were adjacent to another (AI) with 2 different implant brands/types (Astra Tech and Biohorizons). Papilla height measurements were obtained by measuring the distance between implant shoulder and papilla tip for single implants and adjacent implants seperately. The measurements were recorded every 1. week, 1. month and 4. month. The Pink Esthetic Score (PES) was also used to evaluate the soft tissue appearence. Each parameter was assessed with a score of between 0-2, while a total score of 8 was acceptable 12 was the excellent. No statistically difference was found between 2 implant brands/types. (p>0.05) The comparison of papilla heights between single implants and adjacent implants were found statistically different. (p<0.01) It was found while the interdental papilla was increasing between tooth and implant; was decreasing between implants. For adjacent implants a mean PES of 8.57 was obtained, considered to be an acceptable esthetic score. For single implants a mean PES of 11.72 was obtained. Immediate implant treatment process is an effective approach to maintain the soft tissue esthetics, has similar survival rates when compared to conventional methods; however, the single implant scenario demonstrated better clinical esthetic results than those implants adjacent to another.
