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

Clinical Evaluation of the Effect of Low Speed Drilling Versus Conventional Drilling Technique on Crestal Bone Level in Maxilla. A Randomized Controlled Clinical Trial

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.

Inclusion Criteria:

• Patients restoring missing maxillary teeth with implant placement.
• Both sexes.
• Age: 25-45
• Mesio-distal dimensions: Not less than 6 mm
• Bone Height: Not less than 12 mm
• Bucco-lingual dimensions: Not less than 8mm
• All measures will be assessed using CBCT.

Exclusion Criteria:

• Sites needing bone grafting or augmentation.
• Heavy smokers more than 20 cigarettes per day.
• Patients with systemic disease that may affect normal healing.
