Low Speed Drilling Versus Conventional Drilling Technique on Crestal Bone Level in Maxilla.(Group A ) A Randomized Controlled Clinical Trial

Not Applicable

• Conditions: Bone Resorption
• Interventions: Procedure: Drilling at low speed; Procedure: Conventional drilling at high speed

• Registration Number: NCT03220815
• Lead Sponsor: Cairo University

Brief Summary

20 patients were selected requiring implant placement and divided randomly into two groups (10 in each group)

* for the study group, starter drill is used to locate the point of insertion as planned then pilot drill is also used to the full desired working length after that all other sequential drills are used at a low speed (50-70 rpm) without irrigation .

* In the study group: implant will be inserted in the low speed osteotomy site. • In the control group: implants will be inserted in the conventional prepared osteotomy site.

* For both groups there is no surgical guide used.

* The flap will then be copiously irrigated with saline in preparation for closure.

* The flap will then be closed using interrupted 4/0 resorbable sutures.
