Summary

* Background Replacement of two missing adjacent teeth is considered a difficult treatment in implant dentistry and even more challenging if located in the anterior region due to aesthetic demands. As well peri-implant bone contour as soft tissue volume is compromised at start of the treatment and difficult to restore. The question is if this reconstruction will be stable in the longterm. Full-scale evaluation of adjacent implant placement with crown rehabilitation in the aesthetic region with a follow-up of at least 10 years is underreported in this field of implant dentistry.
* Main research question The aim of this observational study was to analyze peri-implant bone changes, mucosa levels, aesthetic ratings and patient-reported satisfaction with the maxillary aesthetic region following implant placement with crown restoration after a 10-years follow-up period.
* Design (including population, confounders/outcomes) The study design is an observational study of a group of patients with two missing adjacent teeth in the maxillary aesthetic region which was treated 10 years ago with dental implant placement and an implant-supported restorations.

Outcomes: primary outcome is the change in marginal peri-implant bone level 10 years after placing the definitive restoration. Secondary outcome measures will be implant and restoration survival and changes in interproximal peri-implant mucosa, midfacial peri-implant mucosal level , aesthetic outcome assessed by means of an objective index and patients' satisfaction using a questionnaire.

• Expected results Stable peri-implant bone levels, stable peri-implant soft tissue levels, high implant and restoration survival rate and satisfied patients.

Conditions

  • Missing Teeth

Interventions

DEVICE

Two endosseous dental implants (NobelReplace Groovy®) were placed 10 years ago

All patients were 10 years ago referred to the Department of Oral and Maxillofacial Surgery (University of Groningen, University Medical Hospital) because of having two failing teeth in the maxillary aesthetic region and were treated with dental implant placement and implant-supported restorations. Patients will have a regular routine control visit (as part of regular follow-up of these patients)
