Download brochure in PDF

In this case we were treating a 40-year-old female patient, without background health issues, who previously underwent a failed root canal treatment and apicoectomy, followed by persistent cyst and pain. The patient was referred to Dr Carmy for treatment from the previous surgeon. Using the Root Shield technique, 16mm DSI implant was used (immediate 1-stage placement) , along with a xenograft and membrane on the buccal side. A 3mm gingival height restoration was placed, based on the DSI ti-base within four months of treatment. This appointment marks a 12-month recall, post-ops are included.
