Bone Level Tapered Implants in the Maxillary Esthetic Zone: A 1-Year Prospective Case Series in Healed Sites

Int J Oral Maxillofac Implants. 2022 Jan-Feb;37(1):120-127. doi: 10.11607/jomi.9163.


Purpose: Bone level tapered implants have an advantage in terms of stability and less need for additional bone augmentation procedures in healed sites, which might be advantageous for the esthetic zone. The aim of this study was to assess the clinical, radiographic, and esthetic performance of bone level tapered implants placed in healed sites in the maxillary esthetic region during a 1-year evaluation period.

Materials and methods: Thirty participants (15 male, 15 female) with a single-tooth diastema that had healed without an alveolar ridge preservation procedure received a bone level tapered implant. Buccal bone augmentation procedures were performed at implant placement if the labial bone wall thickness was < 2 mm. A provisional crown was connected after a healing phase of 3 months. A definitive crown was placed 3 months after the provisional restoration. Implant stability, peri-implant soft and hard tissue health, esthetics, and patient-reported outcomes were recorded.

Results: All the placed implants demonstrated good stability. A labial bone augmentation technique was needed in 23 of the 30 cases. The median implant stability quotient value was 73 (68;76) at implant placement and had increased to 79 (76;81) when the definitive restoration was inserted (P < .005). All patients were present at the 1-year evaluation, and none had lost an implant. The mean loss of marginal bone was 0.07 ± 0.10 mm. The midbuccal mucosa-level recession was 0.14 ± 0.40 mm. There was an overall gain in papilla height: +0.05 ± 0.60 mm mesially and +0.06 ± 0.53 mm distally. Median values of the pink esthetic score and white esthetic score were 6 (4;7 interquartile range) and 8 (7;8.3 interquartile range), respectively. The participants' mean overall satisfaction was 90.1 ± 6.5 on a visual analog scale. No complications occurred.

Conclusion: It can be concluded from a 1-year followup that treatment with the bone level tapered implant system resulted in good implant stability, healthy peri-implant soft and hard tissues, satisfying esthetics, and good patient-reported outcomes.
