Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the present study is to test whether there is a difference in the marginal bone level change between implants with and without cantilevers.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* male and female patients 18 years to 80 years of age
* no general medical condition which represents a contraindication to implant treatment
* two adjacent missing teeth in the maxilla or mandible in positions of premolars and molars
* at least one tooth present adjacent to the edentulous space
* indication for implant treatment is given
* at least 8 mm of vertical bone height in the mandible allowing for the placement of a 6 mm implant (2 mm safety distance to inferior alveolar nerve)
* at least 4 mm of vertical bone height in the maxilla
* signed informed consent after being informed

Exclusion Criteria

* smoking of more than 15 cigarettes a day (clinical studies show an increased failure rate of implants in heavy smokers)
* poor oral hygiene after hygienic phase (Plaque Index over 30 %)
* active periodontal disease
* pregnancy or breastfeeding at date of inclusion
