Conditions
Interventions
Group 1: Long-term observation of all operated teeth over 120 ± 12 months after intervention with regard to the change in attachment levels (gains or losses) between T0 (before surgical intervention)

Inclusion criteria
Inclusion criteria: (1) Implementation of regenerative procedures for the therapy of intraalveolar bone defects at the department for periodontology at the center of dentistry and oral health (Carolinum) of the Johann Wolfgang Goethe University Frankfurt since 2004 (2) written informed consent
Exclusion criteria
Exclusion criteria: (1) missing written informed consent (2) Underlying disease or condition (e.g. heart valve replacement) that require antibiotic prophylaxis for measures that trigger transient bacteraemia (e.g. assessment of pocket probing depths and attachment levels)
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in the vertical attachment level between T1 and T2 measured as the distance to the nearest 0.5 mm between the bottom of the defect and the cemento-enamel-junction at the intraoperatively most severely affected measuring point (highest attachment loss). | — |
Secondary
| Measure | Time frame |
|---|---|
| (1) Change in the vertical bone level between T0 and T2 measured in 0.5 mm with forced sounding ("bonesounding") as the distance between the noticeable defect floor and the cemento-enamel-junction (2) Change in pocket probing depth measured to the nearest 0.5 mm as the distance between the gingival margin and the bottom of the defect between T0 and T2 or T1 and T2 (3) Changes in the plaque and gingival index (five codes, 0-4 each) between T0 and T2 or T1 and T2 as detectable plaque or bleeding at the gingival margin with a blunt periodontal probe or percentage change in the plaque control record and gingival bleeding index between T0 and T2 or T1 and T2 (4) X-ray bone defect filling assessed based on the overlay of standardized bitewing radiographs for T0 and T2 (if available) (5) Smoking habits (active smokers, former smokers, non-smokers) on request and by testing the CO2-content of the exhaled air (6) Adherence to supportive periodontal therapy (regular SPT: never exceed the recommended SPT interval = 100%, i.e. with a recommended SPT interval of 6 months, a 12-month interval still fulfills regular SPT, a 13-month interval corresponds more irregularly SPT) and if so, in what rhythm or how many SPT sessions you have completed in total | — |
