Two‐Piece Zirconia Implants in the Posterior Area: Case Series With at Least 12 Months of Clinical and Radiographic Follow‐Up

ABSTRACT Objective This case series aimed to describe the clinical and radiographic performance of a new two‐piece ceramic implant system in single‐tooth posterior sites, with at least 12‐month follow‐up. Materials and Methods Twenty‐two two‐piece zirconia implants placed in posterior sites of the upper and lower jaws of eighteen patients were included (6 males and 12 females; mean age 55.11 ± 14.14). Cone beam computed tomography (CBCT) was used in all cases for surgical planning, and periapical radiographs were used in the immediate postoperative period and implant follow‐up consultations. Implants were installed in healed sites or fresh sockets, with or without immediate provisionalisation. When necessary, a bone substitute was used to fill gaps in immediate implant sockets. Three months after surgery, the temporary prostheses were removed and seven lithium disilicate crowns were created by impression with addition silicone. All patients were surveyed on their satisfaction with the aesthetic results of the treatment using a Visual Analogue Scale (VAS). Results The patients were followed‐up for at least 12 months (mean 15.2 months [±0.429]), during which time clinical and radiographic success was observed in terms of osseointegration, stability at the marginal bone level (mean marginal bone loss 0.09 mm [±0.146]) and peri‐implant health in all cases. On the VAS, 17 patients reported being ‘very satisfied’ and one was ‘satisfied’. No mechanical or biological complications were observed during this period. Conclusion The two‐piece zirconia implant system used in this report is a safe and reliable potential alternative in oral rehabilitation involving posterior teeth, with success observed over 12 months of follow‐up.
