Due to the patients previous periodontal history, it was de- cided to use Straumann Stand- ard plus implant in this case. The design of this implant in- corporates a 1.8mm polished collar above the active surface of the implant. This results in the implant-to-abutment junc- tion being located 1.8mm su- periorly to the bone crest. Surgical Procedure The patient was given 400mg Ibuprofen and a Chlorhex- idine mouth rinse before the surgery began. The pro- cedure was carried out under intra-venous sedation using Midazolam. The lower incisors were removed using periotomes and forceps. The sockets were curetted and thoroughly ir- rigated. A crestal incision with distal relieving incisions were made. Due to the CBCT and surgical stent only a small lingual reflection was necessary. Implant placement was carried out using standard ITI protocols. Two Straumann SLA-Active standard plus implants of 4.1 x 10mm were placed. The implants exhib- ited excellent primary stabil- ity with an insertion torque of greater than 35Ncm. The patients’ bone quality was estimated to be type D1-2 (Le- kholm & Zarb 1985). Due to the high primary stability and good bone quality it was decid- ed to adopt a single stage sur- gical protocol, thereby plac- ing healing abutments over the implants. The site was closed using 5,0 PGA sutures and a tooth sup- ported denture replacing the lower incisors was fitted. Care- ful examination of the denture was carried out to ensure there was no contact, or transfer of occlusal load onto the implants from the denture. The patient was seen seven days after sur- gery for suture removal and review. The patient healed without incident and due to the favourable lingual un- dercuts of the lower teeth was able to comfortably wear the denture during the healing process. Due to fi- nancial reasons the planned implant placement for the UR4 site was deferred until a later date. After eight weeks of heal- ing, fixture level open tray impressions were taken in Impregum (3M ESPE), and 4-unit screw retained bridge was fabricated. The tooth set of the denture was duplicated on the final bridge as the patient ‘The aim was to provide the patient with a screw retained bridge with access holes ’ Laboratory made screw retained por- celain bridge on Straumann Sync Octa abutments Appearance at fit
