Immediate implantation and soft-tissue preservation with PMMA temporary abutment combined with the extracted tooth

Background: Nowadays, there is an increased demand for aesthetic restorations with healthy peri-implant soft tissue. Immediate implantation and temporization could facilitate the preservation of the original soft tissue architecture. A possible scenario could be the application of PMMA (poli metil-metacrilate) temporary abutments with proper contour of the peri-implant mucosal surface. Description: A 30-year-old female patient visited the dental office. The level of the mucosa and the papilla next to the broken tooth harmonized with the adjacent teeth and soft tissues. The treatment plan aimed to preserve the current soft tissue conditions. A bone level implant (Bone Level Tapered SLActive, Straumann) was placed immediately after the extraction with xenograft bone substitute material (Botiss, Cerabone) to promote the preservation of the bone architecture. Screw-retained temporary crown in infraocclusion was immediately placed on the implant. The temporary crown was fabricated by bonding the extracted tooth to a modified PMMA temporary abutment. After the maturation of the peri-implant mucosa and complete integration of the implant, an open tray A-silicon impression was taken by a customized impression coping. The emergence profile of the tem- porary crown was replicated by pattern resin-modified impression coping. The final restoration was a cementable e.max crown seated on a customized zirconia dioxide abutment. The zirconia dioxide abutment was cemented to its titanium variobase and it resembled the shape of the temporary abutment and seated perfectly into the emergence profile.
