Sealing Socket Abutments (SSAs) in Molar Immediate Implants with a Digitalized CAD/CAM Protocol: Soft Tissue Contour Changes and Radiographic Outcomes After 2 Years.

Immediate implant placement in molar sites has the potential to improve the patient experience by reducing the number of appointments and the overall treatment time. However, primary closure remains a technical challenge. The present prospective case series evaluated the soft tissue contours and the radiographic bone levels of 17 patients who received immediate implants in molar sites and a digitally customized CAD/CAM sealing socket abutment. At the 2-year follow-up, the mean buccal tissue contours at the most coronal portion were reduced horizontally by an average of 1 mm at 1, 2, 3, and 4 mm below the gingival margin. A mean 0.53-mm apical migration of the gingival margin was seen, and the mean interproximal bone level at the 2-year follow-up was 0.89 mm. The use of CAD/CAM-generated customized healing abutments in immediate molar sites yielded minimal hard and soft tissue changes at the 2-year follow-up.

Immediate implant in the posterior region combined with alveolar ridge preservation and sealing socket abutment: A retrospective 3D radiographic analysis.

BACKGROUND: Customized sealing socket abutment (SSA) has been claimed to optimize the peri-implant hard and soft tissues in type 1 implant placement. However, the evidence to claim the benefits of this technique over the use a conventional healing abutment remains weak. PURPOSE: The aim of this retrospective study was to provide a 3D-radiographic evaluation of hard tissues changes following immediate implant placement in molar sites combined to ARP technique and installation of SSA. MATERIALS AND METHODS: Baseline and follow-up (FU) CBCTs (from 1 to 5 years) of 26 patients were collected and included in the study. Baseline and FU CBCTs were superimposed and horizontal and vertical bone changes were assessed. RESULTS: A total of 26 patients and 27 implants were included. Horizontal bone remodeling was not significant in any of the measured areas except in the most cervical level, where a mean bone remodeling of 0.73 mm was found. Proximal and buccal vertical bone changes were not significant. CONCLUSIONS: Within the limits of a retrospective study, dimensional alveolar ridge changes 1 to 5 years after immediate implant placement in molar sites with simultaneous ARP technique and installation of SSA seem to be very limited.

Digitalized CAD/CAM protocol for the fabrication of customized sealing socket healing abutments in immediate implants in molar sites.

Immediate implant placement in molar sites has the potential to improve patient treatment experience by reducing overall treatment time and the number of appointments. However, primary closure remains a technical challenge. AIM: The objective of this case series was to assess the final clinical outcome at the 2-year follow-up of immediate implant therapy in molar sites using a digitally fabricated sealing socket abutment (SSA) at the time of extraction. MATERIALS AND METHODS: This case series included 29 patients who received immediate implant placement in molar sites. A digital impression was taken at the time of placement, and a chairside CAD/CAM healing abutment was fabricated and delivered in situ to close the alveolar socket. Clinical assessments were reported with a minimum of 2 years of follow-up. RESULTS: All patients reported uneventful postoperative recovery after 1 week of healing. No implant failures were observed. The assessment by an experienced clinician showed healthy and stable periimplant tissue. CONCLUSION: Based on the results of this study, the combination of an immediate implant placement protocol and a customized SSA seems to be a viable treatment alternative, although this needs to be confirmed by future prospective randomized studies.
