Pressing always takes place within the ideal temperature range for pressing lit- hium disilicate. Thus hardly any reaction layer is created on the surface. This is enhanced by an extermely short press time. The result is a smooth surface and an enormous time savings!

On periapical view a resorbed root was found with a limited radiolucency (figure10) with an unfavorable prognosis. A conservative extraction was planed followed by immediate implant placement. A (Nobel Biocare AB: Gote- berg. Sweden) speedy implant of 3.5x11.5 mm (figure11), was placed in anterior maxilla and restored within 24 hours period with a temporary crown (figure 12). The insertion torque was of 35 N/cm with an implant stabili- ty quotient (ISQ) of 72. The mar- ginal void about 2mm wide was grafted with bovine xenograft bone. Selection of the abutment was done after evaluating the bony level and gingival thick- ness (Figure 13). After 4 months the final ceramic retained crown was placed and designed to re- ceive an occlusal masticatory load (Figure 14, 15, 16). A 4 years follow up showed a very stable satisfying results (Figure17). Discussion The extended treatment period and the need for a provisional prosthesis during healing phase may seem inconvenient to cer- tain patients. Guidelines recommend 3 months of alveolar bone remod- eling following teeth extrac- tion.11 Still the original approach was modified to include imme- diate implant placement and im- mediate provisionalization.12, 13 Immediate provisional crowns should only be proposed with early loading if an appropriate initial insertion torque has been applied.1 On the other hand some re- searches on animal and human have shown that immediate im- plant placement into extraction sockets failed to prevent socket dimensional changes follow- ing tooth extraction. A minimal width of 1-2mm of buccal bone was found to be essential in or- der to maintain a vertical dimen- sion of the alveolar crest14 . The previous implants had to meet Albrektsson et Zarb suc- cess criteria to be regarded as successful.21 The RFA measure- ments were performed using Ostell instrument(Integration Diagnostics AB, Goteberg, Swe- Figure 10: Radiograph showing the resorbed root of the upper left lateral incisor with a limited radiolucency.
