The effect of tent-pole technique on crestal bone stability of dental implants: a one-year prospective randomized controlled clinical trial

Description :

This study consists of a surgical procedure to place 30 Nuvo™ ConicalFIT™ implants divided in two groups of 15 each. In the first group (test group), implants will be placed at equicrestal level and healing abutments (2 mm height) will be connected and submerged (tent-pole technique), while the second group (control group) implant position will be adapted to the site-specific soft tissue thickness (placed subcrestally if needed to allow at least 3 mm for biological width re-establishment) and will have their healing abutments (4 mm height) exposed to the oral cavity. Clinicians will make sure to attain “safe” insertion torque (IT) (IT> 30Ncm) for healing abutment connection. A follow-up for one-year after loading will be done to evaluate crestal bone stability and soft tissue remodeling. To assess buccal bone stability, three CBCTs will be taken, the first before implant placement, a second immediately after the surgery and a third at 1 year after loading. On the other hand, periapical radiographs will further be taken to evaluate distal and mesial bone using the parallel technique with customized registration bite at implant placement and one-year post-loading.
