Evaluation of Implant Site Preparation With Three Different Drilling Systems in Posterior Maxilla (Randomized Controlled Clinical Trial)

Summary

The rationale for conducting this study is to compare between three implant drilling systems (conventional sequential system, single drilling system and osseodensification surgical drills) for implant site preparation in the posterior maxillay region through measuring implant stability and bone density around dental implants. Therefore, the primary objective of this study is to evaluate the primary and secondary implant stability performed by the three types through measuring implant stability quotient (ISQ), whereas the secondary objective is to assess marginal bone loss, the operation time for the osteotomy preparation, and finally bone density through measuring grey values on CBCT around implants for all drilling methods at different evaluation intervals of the study.

Conditions

• Evaluation of Implant Site Preparation With Three Different Drilling Systems in Posterior Maxilla

Interventions

PROCEDURE

patients received dental implants using single drilling system in posterior maxilla

All patients will be operated under local anaesthesia Articaine hydrochloride 4% with Epinephrine (1:100,000). Crestal incision will performed and full thickness mucoperiosteal flap will be reflected to access the site. The implant will be prepared using the new specially designed drill. These drills are available with four drilling lengths (7, 9, 11, 13 mm) characterized by different color codes, and three different diameters (4, 4.5, 5 mm). They allow a single drilling procedure before implant placement in bone with all types. Drilling speed of 1500 RPM and profuse normal saline irrigation will be used throughout the drilling procedure. Tapered implants will be inserted in all patients with insertion torque 30-50Ncm. Suturing of the flap with interrupted sutures, using 5/0 polypropylene suturing material (According to the protocol provided by the manufacturer).

PROCEDURE

patients received dental implants using Densah burs in posterior maxilla

All patients will be operated under local anaesthesia Articaine hydrochloride 4% with Epinephrine (1:100,000). Crestal incision will be performed and full thickness mucoperiosteal flap will be reflected to access the site. Implant sites will be prepared using osseodensification burs (Densah, Versah) at 1200 rpm in the following sequence: (I) pilot (clockwise); (II) WT1828 (counterclockwise), and (III) WT2838 (counterclockwise). These burs have a cutting chisel edge, a tapered shank and non- cutting edges with four or more lands with a negative rake angle. Suturing of the flap with interrupted sutures, using 5/0 polypropylene suturing material (According to the protocol provided by the manufacturer).
