“…Many studies evaluated several factors that can influence the failure rate of both these techniques. Among them, age, sex, etiology and size of the defect seem to modify the failure rate, with female patients, older patients and those affected by degenerative or larger lesions, complex cases, and patients undergoing salvage treatment being more at risk of failures [13,24,25,49,50]. Such profiling of patient characteristics which may influence the outcome were not possible in this series due to the low number of patients, although interesting findings could be underlined for the most suitable treatment indication based on the lesion size.…”
