Flapless Cone Beam Computed Tomography-Guided Implant Surgery with Contextual Transcrestal Sinus Lift Augmentation Using New Bone Compactor Tools

Abstract

In the present paper, the authors present a case report of premolar edentulism in the upper jaw treated through a guided flapless oral implant surgery with contextual crestal sinus lift, performed with a system of manual screw-tapered bone expanders (B&B Dental, San Benedetto, BO, Italy). The surgery was planned by means of dedicated software, through which the data obtained from the CBCT and from intraoral scanner impression were matched, with consequent production of a surgical template. The proposed surgical procedure is minimally invasive, very simple, and fast and ensures good comfort for the patient by avoiding the elevation of mucoperiosteal flaps and uncomfortable malleting maneuvers. In addition, the presented method shows a good degree of correspondence between the ideal position of the implant in the planning phase and the actual one detectable after the surgery.

Counterclockwise Drilling with Different Tapered Drills Condenses the Implant Bed—An Optical Coherence Tomography In Vitro Study

“…Conservative implant bed preparation techniques with minimal bone removal or no-bone removal (instead of cutting bone, displacing bone laterally and apically) can be applied to improve poor BQL [ 14 , 15 , 16 ]. These techniques include osteotomes [ 17 , 18 ], bone compactors [ 19 , 20 , 21 ], and the osseodensification technique [ 22 , 23 , 24 ]. Bone condensation and compaction are achieved, provided the bone tissue’s viscoelastic properties that allow some degree of bone deformation (due to the collagen content), bone compaction, and some degree of bone fractures, which result in the increased bone density of the walls of the treated area [ 17 , 18 , 19 , 20 ].…”

The osseodensification technique also displaces and condenses the bone laterally and apically; the displaced bone particles can act as an autograft; and, primary, implant stability can be increased [ 22 , 23 , 24 ].…”
