30 I I user report _ bone augmentation implants1_2010 The bone loss area was also measured (with im- agingsoftwareImageProPlus4.0).Theseresultsare presented in Table 1. _Immediate implantation in alveolus— Re-opening The sites were re-opened three months after implant installation to install the healing abut- ments. Measurement of the buccal bone level was measuredagainwiththeperiodontalprobe(Figs.5 &11). _Immediate implantation in alveolus— Restorations After gingival conditioning, impressions were taken and the prosthetic restorations were made according to manufacturer’s (Straumann) instruc- tions.Thetwocaseswerefollowedupafteroneyear andtheestheticresultcanbeseenonFigures6and 12. The results show that there was neither loss of tissue nor gingival retraction in the grafted areas. Therefore, the anatomy obtained after implanta- tionwasmaintainedoneyearafterrestoration,en- suring a stable esthetic result. _Sinus lift with simultaneous implantation—Cases presentation Case1wasa47-yearoldnon-smokingmalepa- tient in good general health with a missing maxil- lary right second premolar and sinus pneumatiza- tion. Case2wasa48-yearoldnon-smokingmalepa- tient in good general health with a missing maxil- lary left first premolar and sinus pneumatization. In both cases, the sinus pneumatization was an indication for sinus grafting. Since the remaining boneheightwaslargerthan3mmitwasdecidedto perform a sinus lifting with simultaneous implant installation. The treatment options were presented to the patients and they signed an informed con- sent form. _Sinus lift with simultaneous implantation—Surgical protocol After local administration of anesthetics (Scan- dicaine 2%, Septodont) an intrasulcular incision was performed around the root and a lateral inci- sion was made on the buccal side to gain access to thelateralwallofthemaxillarysinus.Aftercreation of the lateral window, the sinus membrane was carefully lifted and the site was prepared for im- plant installation. Then, the cement was injected against the inner (nasal) sinus cavity up to half of its width, and the implant Straumann RN SP (4.1mmdiameter,12mmlength)wastheninstalled (Fig. 13). Once the implant installed, the rest of the sinus cavity was filled with the cement (Figs. 14 & 16). The suture was made with 5-0 nylon simple Fig. 9 Fig. 10 Fig. 13 Fig. 11 Fig. 15Fig. 14 Fig. 12
