Inclusion criteria
Inclusion criteria: Patients with at least one tooth that has to be extracted in the upper jaw. Reasons for extraction can be periodontal destruction or destruction due to caries or trauma, which precludes tooth preservation. Planned treatmant has to be implant insertion. Precondition for patients in both groups is a tooth or an existing implant as direct neighbor to the tooth to be extracted.
Exclusion criteria
Exclusion criteria: • Persons under the age of 18 and accordingly persons who are not legally competent • Visibel primary need for bone augmentation • Implant insertion through the implant template impossible (insufficient mouth opening) • Heavy smokers (more than 10 cigarettes/day) • Intake of bisphosphonate medication • Pregnant women • Alcohol or drug addicts • Patients with infectious diseases such as hepatitis or HIV/AIDS • Patients with an ill balanced severe diabetes mellitus. The long-term value for blood sugar HbA1c has to be below 6,7 %
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary outcome is the metrically assessed bone preservation after 8 weeks at the time of the implant position planning. For this purpose the digitized impression data of the extraction wound will be aligned to the 3D x-ray (cone-beam computer tomography) and the difference in volume will be calculated using CAD-software. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcomes are patient satisfaction (measured with a visual analogue scale, VAS) at the time of suture removal and examination 7 days after tooth extraction, the qualitative histological analysis of the newly grown bone (11 weeks after tooth extraction, immediately before implatation) and the added value in relation to costs (at the end of the treatment, seating of the restoration). | — |
