Details for the study

Brief Title

Alveolar Management Following Teeth Extraction

Official Title

A Method for Measuring Volume Changes of the Alveolar Ridge During Dental Implantation Using 3D Scanning

Brief Summary

Investigation of the volume stability of the alveolar ridge, the bone structure and soft<br /> tissue appearance at a delayed dental implantation using two bone substitute materials (1.<br /> Human-Spongiosa, gefriergetrocknet, CHB; 2. collacone®)

Treatments and/or Procedures

Collacone

after tooth extraction, the dental alveolus is filled with the bone substitute material (collacone®) and covered with a membrane (mucoderm®)

Human Spongiosa

after tooth extraction, the dental alveolus is filled with the bone substitute material (Human-Spongiosa) and covered with a membrane (mucoderm®)

Outcome Measures

Outcome measures are the tests that investigators perform to prove whether or not a treatment being tested in a clinical trial is having any effect.

Primary

Extent of bone resorption

The main objective is to measure the extent of resorption of the alveolar ridge bone following teeth extraction and alveolar management (socket preservation) and to compare the two authorized bone substitute materials: Human Spongiosa, gefriergetrocknet, CHB + mucoderm® and collacone® + mucoderm® through 3D surface scan. Definition of time points: T-1 = baseline T2 = 1 month after extraction T3 = 4.5 months after extraction = time point of implantation T5 = 1 month after implantation T6 = 3 months after implantation T7 = 6 months after implantation T8 = 9 months after implantation

According to E9 guideline, the assumptions of the sample size calculation and the statistical analysis plan, which was approved by PEI we include "all relevant time points", respective: T-1 (baseline), T2, T3, T5, T6, T7, T8 (see definition above)

Secondary

Histologic bone investigation

A bone biopsy will be taken before insertion of the implant. The bone biopsy will be investigated for structure changes

4.5 months after teeth extraction and socket preservation (T3)

Secondary

Implants stability

The implant stability will be measured 2 times throughout this clinical trial

4.5 months after teeth extraction and socket preservation (T3) and 3 months after implantation (T6)

Secondary

Pink Esthetic Score

Repeated measurement of the soft tissues changes throughout the clinical trial at eight times

T-1 (baseline before teeth extraction), T1 (7-10 days after extraction), T2 (1 month after extraction), T3 (time of implantation; 4.5 months after extraction), T5, T6, T7 and T8 (respective 1, 3, 6 and 9 months after implantation)
