Vertical vs. Conventional Tooth Extraction Reduces Need for Flap Surgery
Objectives: Minimally invasive vertical extraction techniques have evolved in light of the limitations of conventional extraction techniques and flap surgery in preserving the alveolar bone. The aims of the present study were to (i) provide robust data on the performance of the Benex® device, (ii) compare the need for flap surgery using the Benex® vertical extraction system versus conventional extraction techniques for the extraction of non-molar teeth not suitable for forceps extraction.
Methods: We conducted a prospective observational clinical study of Benex versus conventional tooth extraction techniques using an interrupted time series in line with IDEAL framework stage 3 of surgical innovation.
Results: In the Benex® cohort, 276 of 323 (85.4%) non-molar teeth not suitable for forceps extraction were successfully extracted using the Benex vertical extraction system in 240 patients. Of the remaining 47 teeth, 18 required flap surgery, resulting in an overall incidence of flap surgery of 5.6% (95% CI 3.2-8.7%). During the routine care period, out of 94 non-molar teeth in 78 patients that were not suitable for forceps extraction, 21 teeth required flap surgery for extraction, resulting in an incidence of flap surgery of 22% (95% CI: 14-32%).
Conclusions: The results suggest that the Benex® system may be used with a high success rate for extraction of severely destroyed teeth and its use may lead to a marked reduction in the need for flap surgery.
