Studies excluded after quality assessment and reasons for exclusion.

Authors	Study design	Reasons for exclusion
Grunder et al. [7]	Case series	The inclusion and exclusion criteria were not clearly described; it is unclear whether patients were consecutively treated; outcome was possibly assessed by an investigator involved in the treatment; methods used to assess the outcome were unclear; no actual data on the outcome were available.
Fagan et al. [32]	Case series	Patients characteristics were incomplete (teeth not described); site characteristics were incomplete (age not described); patients were not treated according to same intervention (delayed or immediate implant placement); outcome was possibly assessed by an investigator involved in the treatment; methods used to assess the outcome were unclear; no reproducibility data were reported; no actual data on the outcome were available.
Reinhardt [33]	Case series	Patients characteristics were incomplete (conditions around teeth not described); site characteristics were incomplete (age not described); it is unclear whether patients were consecutively treated; outcome was possibly assessed by an investigator involved in the treatment; no actual data on the outcome were available.
